My Jackery 1000 generator and two smaller units are for emergency home use only. I have the Bestek inverter with the cigarette lighter plug as well as the alligator clips to charge directly off my alternator with my little Scion at idle. It's an extra precaution to bypass the cigarette lighter and thus avoid the potential of damaging my vehicles electronics. I have to smile when I remember the old days of having to pump up the old white gas Coleman lantern and stove to make them work on our camping trips. Those were fun days.
I have been charging like this for a while. I think you touched on this in the video, but it's important to remember that a lot of vehicle cig lighter circuits are fused at only 10 amps. A higher wattage charger will blow them. I do not recommend a larger fuse because some of the wiring is only 14-16 gauge. I ran a fused, 8 gauge circuit directly from my battery (not the alternator) through the firewall to the rear seats. Works great and no fire danger. I also use the circuit for a DC to DC converter that charges my 12v Battle Born at 20 amps while I drive.
Is a 10 gauge wire okay with this for charging a bluetti eb150 the white and blue power generator hobo has on the video? Or does it have to be 8 gauge when running straight to battery?
I’ve been using that bestech inverter for at least 4 years and aside from having a noisy fan that kicks on constantly, It is an amazing pure sine inverter and I’ve never had one issue from it. Definitely recommend it for small devices.
You should address using cigarette type 12v port. This test connects directly to your battery which isn't the same thing. My 2003 Toyota 4Runner will only supply 120W through the DC ports in the car and a bluetti EB150 won't charge as it pulls 220W. It seems completely dependent on your cars wiring and fuses.
They are fused to prevent a fire. If you want a higher wattage into the cabin, you need to run a new wire thick enough to support the amount of power you need.
I ran a fused 10awg connector (SAE to rings) to the Bestek (500A pure sine wave unit) from an SAE plug installed on my ‘house’ 100aH camping battery (which I can charge at either 20A or 40A while driving). Since the rings were on the Bestek instead of the battery, I needed to use the SAE polarity reverse adapter, and it got warm after only a few minutes charging my EcoFlow River 2 Pro. I switched the SAE connectors to 45A Anderson Powerpoles, so the heat should not longer generate at the connectors. I don’t want to over stress either my alternator (2012 6-cylinder Sienna) or the battery, so is it OK during steady driving to charge the battery at 40A and the River 2 Pro set at 300 watts max. input ?
I run a twin USB fan on a low setting (out of 3) that draws about 1 amp (fan blades about 4" in diameter). When I go to bed my Jackory 300 is at 100%, in the morning maybe 99%. It throws out enough air for the inside of van, for me anyways. No worries about draining the battery with these little fans.
This is a good piece of kit for ANYONE who owns a vehicle....Whether you do solar or not, whether you live in a van, RV, etc or not.....Go on a road trip with the Family and this will keep their devices charged and running LONGER. It is pretty good if you also forget to charge a device before leaving on a trip. Thank You HOBOTECH!
A big "Thank You" for this video! I have a Honda CRV and a Jackery 1000. When charging the Jackery 1000 from my vehicles 12 volt outlet I was averaging at around 70 watts or so, which is OK, but I was looking for a way to improve on the charging rate. My 12 v outlets are only rated at 10 amps, so they aren't up to the task of charging at a higher rate. I just bought the exact same Bestek 300 watt inverter that you are using and I connected it directly to my vehicles battery for testing purposes. I plugged my Jackery wall charger into the inverter and my Jackery started charging at around 145 watts. This is exactly the same as if I was charging it from a wall outlet at home. I'm really happy to see such an improvement and I will now install a separate battery connected 12 volt outlet to be used by the inverter. I'll make sure that it is properly fused and I will use a battery isolator so that I don't accidently discharge my car battery. I really appreciate all of your time and effort in creating this video.
Bought it 2 years ago when Javier Camacho from Puerto Rico was asking for donations making power banks for victims of Hurricane Maria. He would build 500W Lithium Ion battery banks using 100W solar and this Pure Sine wave inverter. People cried getting this item in their homes!
See now I was just saying in another video that I'm not so into the portable battery units but like knowing whats out there and you have something I can use.. We have a 2001 Winnebago Class A. we have solar and an inverter but most of our RV is running on 12 volts so we only use the inverter then we can to power laptops, TV's Microwave and so on. The coach came with a 300w inverter from the factory that powers both the TV's but problem is the inverter is 20 years old and not a pure sign wave so we getting little buzzing out of the speakers that drives me nuts.. This unit is a perfect replacement AND the best part is I went to your amazon site to buy and and got 20% off. Amazon is offering a 10% discount AND your 10% is cost me $37.99 with tax and free prime shipping.. Thanks Tom.. you rock!!
I have had one of those for almost two years now and it has worked well to charge my ebike battery hundreds of times while my solar keeps up with it on my RV.
Are you running it through your van cigarette lighter? If so, do you know what kind of efficiency loss there is or what size fuse you have in it? I want to draw 144 watts to charge my ebike battery from a trailer house battery. But it is fused at 15 amps which means I can only draw about 180 watts from the house battery. If the inverter needs more than 180 to get me my 144 it obviously will blow the fuse. Thanks.
@@JohnC88lvb I haven’t actually measured the draw but I know my ebike charger starts drawing about 140 watts but within 15 minutes or so it is down under 100 watts and that inverter ran the charger just fine and I think my cigarette socket is also fused at 15 amps
The little BESTEK 300W came in the other day. Does it's thing most well. Ran this one for over two hours pulling approx 220W with Zero Issues. Happy Camper. Was able to get 100W out of the thing NO BATTERY connected to two 100W Panels direct.
Thank you for reviewing the BESTEK 300w Inverter. I had been considering getting a small inverter for the car and also for charging some small devices off of my very small scale solar setup. It is just the ticket for charging the small devices, phone, tablet and laptop. It also opens the door to having another way of charging a future solar generator, to be purchased later on. Have a great day!
I have a everstart 120w inverter and I've been using for sort of the same hack with my 200w MaxOak power station. It charges faster off the inverter while driving then the 12v plug. I also use it to top of my house batteries by combining it with a battery charger/maintainer when the sun is weak/sky cloudy. I might grab one of these at this price as I've been looking for a larger, but not too large cig plug inverter between 300w-500w.
I mean depending on how long they last im sure there are heatsinking inside and the fan but id like so see the outside also but i guess for what $30 or $40 what are you going to do
I just got mine today. I tested it with my battery charger and my 5000 pound winch. It runs my battery chargers just fine and I can also power so many different devices. I will be charging my Jackery 160 and my Jackery 500 with this inverter. Thank you for the review👌
Thanks for the info. Recently used my jackery to power a iceco fridge off grid. Had some trouble keeping the battery charged. This definitely would have helped during the drive in order to arrive at the destination with a topped off battery! I just ordered one!
Very interesting that it can charge large generators like the Blue Yeti. Would this also be compatible and the case for charging the Ecoflo Delta as well ?
Just a FYI to users. Good luck trying to pull 300W from a cigarette lighter in your car. It's not going to work and you'll blow fuses. This thing needs a proper dedicated connection to the alternator/battery with a ~35-40A fuse.
I don't suggest pulling over 250w with this. Keep it under 20 amps as that's the limit for most vehicle wiring. Some older models may only have a 10 amp fuse, but most are 15 or 20. I also believe the standard in the U.S. is 115vac +/- 5v. So some call it 120 some call it 110.
The Bestek does recommend that you only use 150W or less through cigarette lighter. Just wanted to make sure people were clear about that! But I bought the Bestek due to this review (just the one that is aluminum, so I could screw it down)
Right now 12-06-19 Amazon has a coupon for 20% off and it will still let you use your code so your getting 30% off. Great test. Thanks for useful information videos. 👍
I use these inverters to build battery backup units for CPAP machines for friends and the needy. They work great and are very reliable.I just ordered 6 more with your promo code.
The wattage a 12VDC output will charge the power station at depends almost entirely on the actual output voltage of that 12VDC output. If it's something reasonable, like 13.6V, then you'll get about 100W. A lot of "12V" outputs (from vehicles and varying brands of power stations), however, are sub-standard and only output e.g. 12.8V or even lower. The voltage drop prevents power stations from charging at 100W from such outputs. Unfortunately, there are a lot of problems trying to charge a power stations or anything else from a vehicle's 12V battery or 12V system at more than around 100W. Not just fusing on the 12V "power socket", but even if you tap off the battery directly the alternator might get unhappy. IMHO It just isn't worth potentially breaking your vehicle. And when charging from an AC source, the power station might try to pull more than you can reasonably supply. If you are trying to charge an Oukitel P2001 for example, its AC input runs 1100W and there is no way to lower it. At least with the DC/solar input, you can control the current a bit better. And the way to do that is with a DC-to-DC converter. So if you want to charge at 100W or so, use the 12V output directly. If you want to charge at 200W (assuming the vehicle can handle it), use a 12V-to-24V DC-to-DC converter. To be completely honest, I find using a 12V-to-24V converter to be the best all-around solution.... nearly all power stations will charge at roughly 200W - 250W which is still low enough not to melt the vehicle's alternator. -Matt
Was excited to try this with my newly purchased Jackery 1000 and it blew the fuse to both cigarette outlets that I tried. Prof. you might want to update this video because people dont always look in the comments before taking your advice.
Cigarette outlet on my car is only rated to 180 watts. To get the most of the inverter and get higher wattage, you need to hook it to directly to the battery just like he said at 6:30 in the video
John Sevilla Yes, this is kind of a point easily missed. My car has a 15A fuse, so 180 watts. The Bluetti comes with a 200 watt AC adapter, so it will blow my fuse too. I’m glad I did not buy this inverter.
Thanks Mr Hobotech! Just pulled the trigger on the Bestek 300, from your link. Mostly for charging devices or power tool batteries when plugged into a 100ah LiFePO4.
great test. just curious if I am using a cargo van or an SUV would doing this put extra wear and tear on my battery/alternator? someone was telling me recently that if you have a battery bank built into your vehicle it is bad to try and charge off the alternator without getting a new alternator that is designed to handle the extra load.
Thanks for answering my question. I thought it would work but did not know which inverter to purchase. It's too smoky to get decent solar here in California now, so AC from home power plug in wall and DC from my car are my only options for now. I just ordered my BESTEK 300. It will get here at approx. the same time my BLUETTI arrives. I want to be prepared in the event we loose AC.
Hallelujah!! this is what I needed! Sold me. Just ordered one. This is more efficient than the solar panel on a cloudy day; Don't have to be a rocket scientist to figure this out. I could plug my Jackery 200 into the explorer and then into the bestek and charge both while driving I would think
I have a 3000 watt inverter on my truck that i use to charge my pecron 2000 on works great. The inverter is a pure sine wave inverter made by road pro. My truck is a 3500 dodge with a 6.7 diesel engine and two batteries.
Well you are quite the salesman, I did order this morning one of the inverters from your site and promo code. I really want to get a 240 w. Jackery solar charger but I believe they will be coming out with a newer one that will charge faster and all I am looking for is the regulated 12v feature on the device. Everything in my van runs off 12V. But I did get the 300w inverter to charge the Jackery just in case I cannot wait for the new model if there is going to be a newer model. As always I enjoy your reviews.
Unfortunately as others have mentioned with the newer EB150/240 wall chargers from Bluetti this won't work through the cigarette lighter because they are around 250Watt (older chargers were ~180 Watt). Bluetti has come out with the DC Charging Enhancer D050S which allows you to charge from the cigarette lighter. I bought one and it charges at about 100Watts.
Love your passion! I asked Amazon this question about the Bluetti...still have not got an answer. Yes you covered this intelligent yet inexperienced beOtch's fear of sucking the life from my Grand Caravan battery and popping fuses and frying wires! I even wanted to know if I could just dual-ize my battery...personally it is too much bother.. My van is pretty generic and does not have that inverter option. What I have is 160 W 13amp...with two options direct or while running. I am looking into a guaranteed tweek to fuse up...Yes! You have satisfied my needs Professor Hobo! Thank you! (and I am an 80's blow dryer addict. If I can't use my 1500W hair dryer...even when camping...it is a bad hair day. So serious about that!) I imagine grooming that wonderful Professor Goatee requires some hot air and shaping to get it just right?
Thx so much for this video! Been trying to figure out why my '17 4Runner DC port connected to a Marxon G1500 solar generator kept cutting out. I suspected voltage drop below 11v from the car battery tripped the battery management on the G1500, but wasn't sure of a good way around this except for putting a 2nd battery in the Runner. Looks like this inverter will be just what I need to keep the battery charged and keeping my fridge running for days. Very helpful info!
I bought a 12/24v 15A step up converter on Amazon for $15. Wired it to my battery with 10awg wire and a 20amp fuse. I can charge my EB70s at 190watts while I drive.
Just for fun I hooked up my Victron pure sinewave 375 watt inverter to my Toyota Sienna's cig lighter and charged a raw LIFP04 pack off it with the vehicle running, and measured peak wattage output from the cig lighter at 150 watts, more than the rated/suggested 120 watts. Voltage on the cig lighter output was 14.6, so the inverter was drawing around 10 amps with the LIF04 charger I was using hooked up to it to charge the house battery. Kind of on the edge with the ratings for that circuit. I think this would be quite feasible with direct wiring from the car battery to the inverter. I didn't blow the fuse but probably close. Now to figure out how to get through the firewalll. Maybe do it this way rather than the usual DCDC type solution,as I already have the inverter and my power needs are not immense...just a bunch of 5V USB appliances and a single Dometic fridge which I usually run off the LiFPO4 house battery. This setup is probably no more than 75% efficient as the LIFP04 charger is rated at 8 amp/12V - around 100 watts. So much of that 150 is going to the inverter I guess. Nonetheless a good concept.
I’m not sure I would want it work at 11 volts. That just means it could possibly drain my battery so the car won’t start plus put unnecessary wear and tear on the battery. Not sure if pure sine wave is of benefit for a simple charger but nice to see a lower wattage inverter that has that and it seems to be a reasonable price. I wish there was a way to regulate the charging speed on my ac200p a 700 watt charger that you can adjust from 200-700 watts via software would be pretty sweet. Thanks for sharing! And yes jackeerys generally are slow to charge. . Probably good for battery life but not for real world use.
This is actually my current method of charging. I'm using an EverStart 400W and a DBPower 505wh solar generator. Using the charger that came with it lets me charge at 120 watts. No PD charging and a maximum charging rate of 150watts according to the manufacturer means I'm pretty close to maximum! A word of warning don't use the cigarette lighter if you can help it and wire this straight to your battery. Not only does this avoid blowing a tiny fuse but I actually had my cig lighter plug itself burn out.. still need to fix that. Either way great video, also curious it looks like just a DC-DC buck/boost converter might do the trick? My solar generator's charger charges it at 24v so matching that with 140watt output from the DC source directly seems like it would also be more efficient on my poor 80A alternator hah.
I won one of these about 3 years ago so it's been out for a while and mine still works great I never thought about charging my solar generators with it though and thanks for testing to see if it was pure sine I always wondered it seemed like too good of a deal
I tried charging a Bluetti EB150 with a Bestek 300w inverter. It will not work if a 15 amp fuse is connected to the cigarette lighter or power port. It will blow the fuse as soon as the inverter is plugged into the Bluetti. Notice at 10:00 in the video that the inverter is connected directly to the battery.
This is good to know. I tried plugging a 12v car battery into my Pecron e3000, and it was weak sauce... only charged at 85-90W. My supplied charger is 600w, so I will have to find a 24v 300W charger to pair with the little Bestek.
I’ve got the Bestek 400w. I’ve been charging my Schumaker all in one battery charger for years off it. Using the dc cigarette lighter input. The Bestek will run a portable fan on it aswell as a charger. Thanks for sharing
It came out to like 32 bucks with tax....there's a 20 off coupon on site plus the P3K code, that's a decent deal for a sine wave inverter for laptops and more sensitive electronics than just a modified sine wave.
Mark, thx for saying something as so many are just one or the other. I just ordered it & got both discounts, too: the 20% coupon off was $9.20, the P3KDY9Z8 code was $4.60 which dropped the total from $45.99 down to $32.19 (plus sales tax). 😎
I’d like to see this work in an actual vehicle where the alternator and battery are at play versus this lab. I’m doubtful it will work since I’ve tried this multiple times in different vehicles with no luck. Maxoak informed me personally that they’ve never actually tested this themselves which makes their EB150 crap since you can’t charge while driving (what better time to recharge than while driving hours to next destination?). I challenge HOBOTECH to post a video of this working in a vehicle while driving.
Your on track with this charging info posting . I look forward to looking at your other gadgets . The adjustable output with the cooling fan will certainly be enough to get me in all kinds of trouble . . . Lol . Thanks Hobo Tech
My River 2 literally melted the original 12v cord and Ecoflow replaced it with a newer one that has a thermal fuse thats totally useless. I bought a USB C charger and can get 29w input but the charger still gets warm and has shutdown a time or two. I'm typically trying to recover 34-40% and the USB-C can do that in a few hours. Will i see the same 12v overheating issue with this unit?
I have the EcoFlow River Pro. It charges at 650 watts from a house outlet. The Kilowatt shows it is pulling 750 watts from the house outlet. I’m getting a 1200 watt Bestek inverter (hooked directly to the car battery with thick wire) so I can charge the EcoFlow in less than 2 hours 😊 The solar input is only 200watts. I have a 24 v 10a China power supply that puts 200 watts into the solar input. It works off a small inverter too. But that takes 6 to 8 hours. I want to charge the River Pro in less than two hours while I drive. The 1200 Watt inverter should do that easily.
I got a 300w inverter long before I watched your video and it's a "modified" sine wave. I'm wondering what that would look like on your readout. Guess I could research that. Not that it matters much because it still works to charge laptops, run power tools, incandescent lights, etc. without interuption. I've used inverters in the past that were really bad. It was easy to tell by hooking up a Dremel tool, turn it on and you could hear - and feel - it miss a beat about every other second :-)
The Bestek has a decent sine wave almost to full output. Drawbacks...it consumes 7-9 watts just by being plugged in with the inverter switched off. The USB ports are always powered up. The output voltage is 110 volts and never higher. I have several and they are reliable.
So don’t know what I’m doing wrong, but I have an energizer power source pro solar generator and after watching your video I purchased the Bestek 300. I plugged the 300 amp into my jeep and all my power bank does is click there’s no input wattage?
Hi. This is the closest video to answering my question. Can a 12v 100 AH lithium battery be used to extend the capacity of these power stations instead of buying the much more expensive expansion packs?
Just for everyone currently trying to use this work around for the Bluetti, the stock AC adapter outputs 210-220w. If your 12v outlets are wired with 15A fuses, you’ll only get 180w. So unfortunately, unless you can get an older AC adapter from Bluetti that outputs 170w, this will no longer work.
Thank you! I blew 2 fuses today and needed this confirmation. What did you end up doing? Are you able to buy/find an older AC adapter or just scraped this idea altogether?
@@espesp9603 I contacted Bluetti about obtaining an older AC adapter and I don’t think they understood what I was asking. There’s a bit of a language barrier with them. I’m probably just going to have a local car audio shop install a 400w pure sine inverter. They quoted around $300. I’ll wait a bit longer though in case Bluetti starts selling an appropriate car charger.
@@coreybohborey Thanks for the info and response. Yeah I’m going to wait to see if they come out with a car charger too. I am really bummed out it didn’t work. I don’t really want to do the solar panel on the roof. Plan B for me is to buy the Dokio 300 foldable solar panels for $300. I also like your idea of having a 400watt inverter installed... thanks!
Why is everyone so dead set on using the outlets in their car???? Be a man, wire up your own high amp 12V line through the firewall and position it where it is best used. All this takes is some 8 or 6 gauge wire, an inline fuse and your choice of connection to the inverter (just hardwire it)
I bought that max oak eb240 with the idea that i would be able to charge it while driving.. I had every reson to believe it would work. Unfortunately its either over or under volting the eb240 causing it to momentary trip on and off... I wish i had a solution for this
That's a great inverter, thanks for review! Let's say you had a 100Ahr flooded lead acid (LA) 12V battery, used, outside of the vehicle in a tent for a week, and you didn't want to start the car or move the car for an entire week so you're not dealing with your vehicle. You had a different charge controller and solar panel that would quickly charge up the 100Ahr lLA battery. Your 1500 Bluetti is running a lot with a 12V DC fridge 55W all day in hot weather but internally it cycles on 50% of the time. When the 100Ah battery is fully charged from it's solar panels, could you use the 100Ah LA battery to charge your 1500 Bluetti in a DC to DC charger? that is, NOT using an inverter to convert it to AC? I alrady asked RichCell chat and they said no. Why isn't there something like a 12vDC to 12V DC charger, to go from LA to Lithium battery? We jump start vehicles, why can't we do this? Thanks much,
Higher power inverters like this Bestek 300w, with a cigarette lighter plug, are a blown fuse waiting to happen. Most powerports/cigarette lighter sockets in most cars are rated at 10 amps or 120 watts. This will blow the fuse at less than half the rated capacity of this inverter. Personally, I would not use this connected to a power port unless you know for a fact that the port is rated for at least 300 watts. Also, this will put additional load on your alternator so make sure it can handle it. Charging high power items off your vehicle can be tricky. Make sure you do your homework before you start hooking stuff up.
Sorry, but I MUST question this. My 2013 Ram cargo van has a 160 A alternator & 730 A battery. Granted, the cigarette lighter socket may not handle all that, but I don't see why they would put a low amp socket out on a 160 A alternator. This Bestek 300W has an on-off and a failure light---fail-safe, fuse not needed. The AC charger that comes with the EB240 Bluetti, is now rated: In- 120 volts AC at 2.5 A (300 Watts - a match) Out- 42 Volts DC at 5 A (210 Watts- Well within the 68 Volt, 10A max in to charge the Bluetti) (but faster than the lower wattage charger that the EB240 originally came with)
BTW, you need this setup to charge from the car because the 12 volts from the car is UNREGULATED and can vary from 11 Volts to 13.9 volts. The Bestek Pure Sine Wave inverter takes care of that flaky voltage.
Professor, I am contemplating this idea and ask for your scrutiny: I like to have a 1800 watt power station but no solar panels and I will fast charge with the AC output of a large pure sine wave inverter while I am driving (will have breaker and a battery isolator). The mini-van alternator can max out at 150 amps (higher if I need to put on a larger/180 or 200 alternator). The power station is the EF ECOFLOW Portable Power Station DELTA, UPS Power Supply 1260Wh Battery Pack with 1800W (3300W Surge) AC Outlets. It has a fast charing capability when plugged into 110 V AC and the manufacturer advise that that will take about 3-4 hr. BUT the inverter output must be 1500 watts or higher like 1800 or 2000 watts. I think I can find a inverter of that spec. The idea is that I will drive 3 or 4 hours a day and can survive most of the days with this scheme.
Thank you, Tom. Just got it for $28! A 20% discount from Amazon AND your discount code. Also had $5 credit in my acct - worked great! Will be handy to charge my J500 when can’t use my solar. I truly appreciate your reviews and especially the full explanations. Thanks
Hi HOBO, I tried the same thing to charge the EB240. When I plugged the Bestek inverter into the cigarette lighter while the engine was running, the EB240 charged at ~210W. After 2 minutes the cigarette lighter fuse blew and stopped working. The cigarette lighter fuse is 20 amp. If I connect the inverter directly to the engine battery to draw >210W of power; will it work? Is it safe to permanently hookup the wires to the battery terminals and use the inverter to charge while driving? Will this damage my engine batteries in the long run? Can you provide some recommendations on how to safely draw more than 200W from the battery? And what is the max Wattage that can be drawn from the battery continuously as long as the engine is running?
Chuckle I travelled with my big Tom ..solo in a caravan cats really adapt well don’t they ...thanks for the power vids I’ve built my own power box and the inverter is the last leg for it. I’m using a ver old ring power can but could do with a slightly more able one to run a old notebook that I’ve swapped to Linux. That move alone dropped my consumption as it seems to leave windows well in the rear mirror strain wise on the battery. Love the approach. You need a igor assistant
Can I do this with a delta ecoflow 1300? It claims you can go from 0-80% in 1!hr as opposed so 5 hr using the 12 volt charger so this would be fantastic. Also would I need to put a larger fuse in my car charger and could this be harmful to it?
I have the same issue, I am thinking about getting a older laptop charger and putting on a XT60 female plug, this way I can use a smaller 800 watt inverter generator to charge it. Just make sure that the output voltage is correct and you have the polarity correct, Negative to negative and positive to positive. You would only be able to charge at about 100 to 120 watts depending on the charger you find, Goodwill usually has some of them for just a few dollars each. This would then plug into the DC input on the delta flow
Great Solution, I have a Blueetti/PowrOak PS10 -2400 wh. It charges at 210 Watt. If i would put the inverter between the car battery and the powerbank and let it charges whilst driving, would this not drain the battery of the car aswell ? I have no idea how much Watt the alternator charges the car-battery.
in short...car cigarette sockes are fused at 10 or sometimes 15A at 12V, (=120-180W) but some power stations limit theirr 12V DC input even lower to only 8A (=96W). So yes, if you are lucky to have a car lighter socket which is fused at 15A then you can nearly double your charge rate with a device like this to a still fairly low max 180W. But if you have the car socket fused at 10A then you have only minor gains. Also dont try to swap fuses as that is super risky for overloaded wirings burning down your car. Plus, you are basically inverting/converting twice, once from DC car to AC inverter and again inside your powerstatoin back to DC to charge the battery. There are more efficient/faster ways like using a DC DC converter hooked up to the car alternator together with a cutoff relais, which can basically charge powerstations through their solar input theoretically to their max possible W (example ecoflow delta 2 at max 500W)
@HOBOTECH Perhaps charging a solar generator is a good use of the old Modified Sine Wave (MSW) generator many of us have kicking around. In fact, you could create a Pure Sine Wave (PSW) inverter by connecting 12V -> MSW Inverter -> PSW Solar Generator -> Load
I bought this for my Bluetti EB150 to charge in my 4Runner while driving but no luck. The AC wall charger kept toggling on and off. Eventually the 15 amp fuse popped. I can charge in the 4Runner with engine running using the onboard 110 but that turns off once the transmission is in drive. I can't believe the Bluetti cannot be charged in the car while driving. This is a major con and I now regret buying one. I love this channel though!
I ordered the Bestek 300 watt to charge my Jackery 1000 from my 2015 Prius Hybrid. I tried the aux outlet and it worked great for 3 days. ( With engine running. ) Then the fuse blew. I replaced the fuse and it ran awhile and blew again. I didn't have any more fuses so I tried it in the cigarette lighter. That blew the fuse too. The Toyota uses 15 amp micro short fuses. I ordered 2 packages from Amazon and replaced both fuses and now neither my cigarette outlet or auxiliary outlet will work! I thought maybe the fuses might be bad, but I tried several different new fuses and nothing! I am afraid I must have fried something. I was only pulling about 165 watts while charging the Jackery. I don't see that the fuses are blown and I don't see anything burnt in the outlets.
All my vehicles have an inverter. The inverter transmit 120 volt power through 14 gauge extension cord and to my camping trailer. Then I have a standard dc battery charger charging my camper batteries. I can charge upto max power of inverters. I do not need any fancing welding cable to charge my camper battery. The batteries are always properly charged to correct voltage . Bonus they last 10 years plus. As I only discharge to 50%.
Wow..The inventors are really coming out with cool gadgets in the electro world..Now if they can get the cost down on a ;lot of them,that will be great.. enjoy your day..err night
I tried using this with the ecoflow delta using the cigarette lighter in my Suburban but no dice. It powered up but the delta just clicked a few times and went into overload. Any suggestions?
How do we determine if this is too much for our car's alternator, I have a 2014 Honda Odyssey? Also I see there's a 500-watt version of this is this too much for the van?

Greetings, I have a bluetti AC 200Max, does the inverter that is recommended work for me?
I have a questions can I use my power bank to this 300w inverter and also charge my items without using the car cord there or no???
Does this work with an Ecoflow delta 2? There seems to be some additional hurdles with that unit.
My Jackery 1000 generator and two smaller units are for emergency home use only. I have the Bestek inverter with the cigarette lighter plug as well as the alligator clips to charge directly off my alternator with my little Scion at idle. It's an extra precaution to bypass the cigarette lighter and thus avoid the potential of damaging my vehicles electronics. I have to smile when I remember the old days of having to pump up the old white gas Coleman lantern and stove to make them work on our camping trips. Those were fun days.
I have been charging like this for a while. I think you touched on this in the video, but it's important to remember that a lot of vehicle cig lighter circuits are fused at only 10 amps. A higher wattage charger will blow them. I do not recommend a larger fuse because some of the wiring is only 14-16 gauge. I ran a fused, 8 gauge circuit directly from my battery (not the alternator) through the firewall to the rear seats. Works great and no fire danger. I also use the circuit for a DC to DC converter that charges my 12v Battle Born at 20 amps while I drive.
I have a Stanley 140 what can that charge the portable batteries?
I blew my fuse today trying this. Thanks for the info on how to bypass the 10amp fused line.
I’ve done the same with a 400 watt inverter direct and fused to the battery for a Bluetti E150 (1500wh) and get 200 watts. 10 ga wire. 20 amp fuse.
Is a 10 gauge wire okay with this for charging a bluetti eb150 the white and blue power generator hobo has on the video? Or does it have to be 8 gauge when running straight to battery?
If your unit supports multiple charge methods ie 12 volts and 110 why not charge from both in the auto so you can charge at 120 watts
I’ve been using that bestech inverter for at least 4 years and aside from having a noisy fan that kicks on constantly, It is an amazing pure sine inverter and I’ve never had one issue from it. Definitely recommend it for small devices.
You should address using cigarette type 12v port. This test connects directly to your battery which isn't the same thing. My 2003 Toyota 4Runner will only supply 120W through the DC ports in the car and a bluetti EB150 won't charge as it pulls 220W. It seems completely dependent on your cars wiring and fuses.
The exact thing I’m looking for
@Westcoastrocksduhno bro, that has nothing to do with voltage. All that does is create a fire hazard.
12 volt cigarette outlets only support 10 or 12 amps for a max of 140 watts
They are fused to prevent a fire. If you want a higher wattage into the cabin, you need to run a new wire thick enough to support the amount of power you need.
I ran a fused 10awg connector (SAE to rings) to the Bestek (500A pure sine wave unit) from an SAE plug installed on my ‘house’ 100aH camping battery (which I can charge at either 20A or 40A while driving). Since the rings were on the Bestek instead of the battery, I needed to use the SAE polarity reverse adapter, and it got warm after only a few minutes charging my EcoFlow River 2 Pro.
I switched the SAE connectors to 45A Anderson Powerpoles, so the heat should not longer generate at the connectors. I don’t want to over stress either my alternator (2012 6-cylinder Sienna) or the battery, so is it OK during steady driving to charge the battery at 40A and the River 2 Pro set at 300 watts max. input ?
Game changer. Was able to double my charging speed thanks. This is going to help me keep my fan on at night.
I run a twin USB fan on a low setting (out of 3) that draws about 1 amp (fan blades about 4" in diameter). When I go to bed my Jackory 300 is at 100%, in the morning maybe 99%. It throws out enough air for the inside of van, for me anyways. No worries about draining the battery with these little fans.
This is a good piece of kit for ANYONE who owns a vehicle....Whether you do solar or not, whether you live in a van, RV, etc or not.....Go on a road trip with the Family and this will keep their devices charged and running LONGER. It is pretty good if you also forget to charge a device before leaving on a trip.
Thank You HOBOTECH!
A big "Thank You" for this video! I have a Honda CRV and a Jackery 1000. When charging the Jackery 1000 from my vehicles 12 volt outlet I was averaging at around 70 watts or so, which is OK, but I was looking for a way to improve on the charging rate. My 12 v outlets are only rated at 10 amps, so they aren't up to the task of charging at a higher rate. I just bought the exact same Bestek 300 watt inverter that you are using and I connected it directly to my vehicles battery for testing purposes. I plugged my Jackery wall charger into the inverter and my Jackery started charging at around 145 watts. This is exactly the same as if I was charging it from a wall outlet at home. I'm really happy to see such an improvement and I will now install a separate battery connected 12 volt outlet to be used by the inverter. I'll make sure that it is properly fused and I will use a battery isolator so that I don't accidently discharge my car battery. I really appreciate all of your time and effort in creating this video.
Did it blow your cigarette lighter fuse? Mixed comments here
Bought it 2 years ago when Javier Camacho from Puerto Rico was asking for donations making power banks for victims of Hurricane Maria. He would build 500W Lithium Ion battery banks using 100W solar and this Pure Sine wave inverter.
People cried getting this item in their homes!
👍 🌹 bless you
please tell us more about that or do you have a link?
Thanks for your kindness!
Yeah, Javier is awesome. Great, creative vids too ❤
The PR government stole and wasted or resold millions of dollars in supplies.
See now I was just saying in another video that I'm not so into the portable battery units but like knowing whats out there and you have something I can use.. We have a 2001 Winnebago Class A. we have solar and an inverter but most of our RV is running on 12 volts so we only use the inverter then we can to power laptops, TV's Microwave and so on. The coach came with a 300w inverter from the factory that powers both the TV's but problem is the inverter is 20 years old and not a pure sign wave so we getting little buzzing out of the speakers that drives me nuts.. This unit is a perfect replacement AND the best part is I went to your amazon site to buy and and got 20% off. Amazon is offering a 10% discount AND your 10% is cost me $37.99 with tax and free prime shipping.. Thanks Tom.. you rock!!
I have had one of those for almost two years now and it has worked well to charge my ebike battery hundreds of times while my solar keeps up with it on my RV.
great to know ...i was wondering if that would do the trick
Are you running it through your van cigarette lighter? If so, do you know what kind of efficiency loss there is or what size fuse you have in it? I want to draw 144 watts to charge my ebike battery from a trailer house battery. But it is fused at 15 amps which means I can only draw about 180 watts from the house battery. If the inverter needs more than 180 to get me my 144 it obviously will blow the fuse. Thanks.
@@JohnC88lvb I haven’t actually measured the draw but I know my ebike charger starts drawing about 140 watts but within 15 minutes or so it is down under 100 watts and that inverter ran the charger just fine and I think my cigarette socket is also fused at 15 amps
@@jingeman Thanks. That’s helpful.
I bought one last week and tried to charge my Ecoflow Delta with and it did nothing. I think I heard a clicking sound so I unplugged it.
Got to say it on this item.....SOLD....... thanks Hobo for showing us this item and the time it took you to review it so well🎩
instaBlaster
The little BESTEK 300W came in the other day. Does it's thing most well. Ran this one for over two hours pulling approx 220W with Zero Issues. Happy Camper. Was able to get 100W out of the thing NO BATTERY connected to two 100W Panels direct.
Thank you for reviewing the BESTEK 300w Inverter. I had been considering getting a small inverter for the car and also for charging some small devices off of my very small scale solar setup. It is just the ticket for charging the small devices, phone, tablet and laptop. It also opens the door to having another way of charging a future solar generator, to be purchased later on. Have a great day!
So 300w power invert cant charge a car battery? What is a good watts power invert to charge a car battery.
Hobotech, you twisted my arm with your sales job. I bought that pure sine wave inverter and used your discount code
I bought this and it is exactly as advertised. I love it
I have a everstart 120w inverter and I've been using for sort of the same hack with my 200w MaxOak power station. It charges faster off the inverter while driving then the 12v plug. I also use it to top of my house batteries by combining it with a battery charger/maintainer when the sun is weak/sky cloudy. I might grab one of these at this price as I've been looking for a larger, but not too large cig plug inverter between 300w-500w.
I've been eyeing the Bestek for awhile. I'm impressed!!!
I mean depending on how long they last im sure there are heatsinking inside and the fan but id like so see the outside also but i guess for what $30 or $40 what are you going to do
For 40 bucks..you can't beat this deal..Thanks for sharing Professor Hobo 😀 👍
i'll second that
I just got mine today. I tested it with my battery charger and my 5000 pound winch. It runs my battery chargers just fine and I can also power so many different devices. I will be charging my Jackery 160 and my Jackery 500 with this inverter. Thank you for the review👌
OH Yah Baby.... This is what I need... Thanks HoboTech !!!
I was looking everywhere for this info,so your right I heard it here first and I subscribed to your channel
Thanks for the info. Recently used my jackery to power a iceco fridge off grid. Had some trouble keeping the battery charged. This definitely would have helped during the drive in order to arrive at the destination with a topped off battery! I just ordered one!
Very interesting that it can charge large generators like the Blue Yeti. Would this also be compatible and the case for charging the Ecoflo Delta as well ?
Just a FYI to users.
Good luck trying to pull 300W from a cigarette lighter in your car. It's not going to work and you'll blow fuses.
This thing needs a proper dedicated connection to the alternator/battery with a ~35-40A fuse.
That's 300 watts @110 volts, 2.72 amps @12 volts.
You are wrong
To generate 300W at 110V you will need to feed in at least 300W at 12v. So, 300/12 = 25A.
Energy can't just magically appear.
@@christianholmstedt8770 Pardon me, but what is with 110vac..?? 110vac hasn't been used in this country for more than 60 years!
I don't suggest pulling over 250w with this. Keep it under 20 amps as that's the limit for most vehicle wiring. Some older models may only have a 10 amp fuse, but most are 15 or 20. I also believe the standard in the U.S. is 115vac +/- 5v. So some call it 120 some call it 110.
@pjf
The output of this one is 110VAC. So what are you asking again?
The Bestek does recommend that you only use 150W or less through cigarette lighter. Just wanted to make sure people were clear about that! But I bought the Bestek due to this review (just the one that is aluminum, so I could screw it down)
Right now 12-06-19 Amazon has a coupon for 20% off and it will still let you use your code so your getting 30% off. Great test. Thanks for useful information videos. 👍
Best $40 spent ever...thanks ! Hobo is the best reviews channel for tech..love it..and Ode is best cat in UA-cam...:)
I use these inverters to build battery backup units for CPAP machines for friends and the needy. They work great and are very reliable.I just ordered 6 more with your promo code.
Do u have a video, that’s what I need the battery for
The wattage a 12VDC output will charge the power station at depends almost entirely on the actual output voltage of that 12VDC output. If it's something reasonable, like 13.6V, then you'll get about 100W. A lot of "12V" outputs (from vehicles and varying brands of power stations), however, are sub-standard and only output e.g. 12.8V or even lower. The voltage drop prevents power stations from charging at 100W from such outputs.
Unfortunately, there are a lot of problems trying to charge a power stations or anything else from a vehicle's 12V battery or 12V system at more than around 100W. Not just fusing on the 12V "power socket", but even if you tap off the battery directly the alternator might get unhappy. IMHO It just isn't worth potentially breaking your vehicle.
And when charging from an AC source, the power station might try to pull more than you can reasonably supply. If you are trying to charge an Oukitel P2001 for example, its AC input runs 1100W and there is no way to lower it. At least with the DC/solar input, you can control the current a bit better.
And the way to do that is with a DC-to-DC converter. So if you want to charge at 100W or so, use the 12V output directly. If you want to charge at 200W (assuming the vehicle can handle it), use a 12V-to-24V DC-to-DC converter. To be completely honest, I find using a 12V-to-24V converter to be the best all-around solution.... nearly all power stations will charge at roughly 200W - 250W which is still low enough not to melt the vehicle's alternator.
-Matt
Way more efficient too since there is no DC-AC and then AC-DC conversion losses with the inverter.
Was excited to try this with my newly purchased Jackery 1000 and it blew the fuse to both cigarette outlets that I tried. Prof. you might want to update this video because people dont always look in the comments before taking your advice.
Why did it blow the fuse if he said it is fine to use in cars ?🤔
It won't work for me either...hmmm
Cigarette outlet on my car is only rated to 180 watts. To get the most of the inverter and get higher wattage, you need to hook it to directly to the battery just like he said at 6:30 in the video
John Sevilla Yes, this is kind of a point easily missed. My car has a 15A fuse, so 180 watts. The Bluetti comes with a 200 watt AC adapter, so it will blow my fuse too. I’m glad I did not buy this inverter.
Thanks Mr Hobotech! Just pulled the trigger on the Bestek 300, from your link. Mostly for charging devices or power tool batteries when plugged into a 100ah LiFePO4.
great test. just curious if I am using a cargo van or an SUV would doing this put extra wear and tear on my battery/alternator? someone was telling me recently that if you have a battery bank built into your vehicle it is bad to try and charge off the alternator without getting a new alternator that is designed to handle the extra load.
Thanks for answering my question. I thought it would work but did not know which inverter to purchase. It's too smoky to get decent solar here in California now, so AC from home power plug in wall and DC from my car are my only options for now. I just ordered my BESTEK 300. It will get here at approx. the same time my BLUETTI arrives. I want to be prepared in the event we loose AC.
Hallelujah!! this is what I needed! Sold me. Just ordered one. This is more efficient than the solar panel on a cloudy day; Don't have to be a rocket scientist to figure this out. I could plug my Jackery 200 into the explorer and then into the bestek and charge both while driving I would think
I have a 3000 watt inverter on my truck that i use to charge my pecron 2000 on works great. The inverter is a pure sine wave inverter made by road pro. My truck is a 3500 dodge with a 6.7 diesel engine and two batteries.
thanks for this review!! just found it and going to get this pure sine inverter and charge my ecoflow delta 2!!
Let us know how you set it up to work in your vehicle
Did it work with delta 2, some commenters says it did nothing?
Well you are quite the salesman, I did order this morning one of the inverters from your site and promo code. I really want to get a 240 w. Jackery solar charger but I believe they will be coming out with a newer one that will charge faster and all I am looking for is the regulated 12v feature on the device. Everything in my van runs off 12V. But I did get the 300w inverter to charge the Jackery just in case I cannot wait for the new model if there is going to be a newer model. As always I enjoy your reviews.
Unfortunately as others have mentioned with the newer EB150/240 wall chargers from Bluetti this won't work through the cigarette lighter because they are around 250Watt (older chargers were ~180 Watt). Bluetti has come out with the DC Charging Enhancer D050S which allows you to charge from the cigarette lighter. I bought one and it charges at about 100Watts.
...and the end music is??? Good stuff! I just bought the BESTEK 300w Pure Sine Inverter. Thank you!
Love your passion! I asked Amazon this question about the Bluetti...still have not got an answer. Yes you covered this intelligent yet inexperienced beOtch's fear of sucking the life from my Grand Caravan battery and popping fuses and frying wires! I even wanted to know if I could just dual-ize my battery...personally it is too much bother.. My van is pretty generic and does not have that inverter option. What I have is 160
W 13amp...with two options direct or while running. I am looking into a guaranteed tweek to fuse up...Yes! You have satisfied my needs Professor Hobo! Thank you! (and I am an 80's blow dryer addict. If I can't use my 1500W hair dryer...even when camping...it is a bad hair day. So serious about that!) I imagine grooming that wonderful Professor Goatee requires some hot air and shaping to get it just right?
Thx so much for this video! Been trying to figure out why my '17 4Runner DC port connected to a Marxon G1500 solar generator kept cutting out. I suspected voltage drop below 11v from the car battery tripped the battery management on the G1500, but wasn't sure of a good way around this except for putting a 2nd battery in the Runner. Looks like this inverter will be just what I need to keep the battery charged and keeping my fridge running for days. Very helpful info!
You always find innovative workarounds...thanks PS - having worked in R&D for many years, I must say you're doing a great job at Branding yourself...
I bought a 12/24v 15A step up converter on Amazon for $15. Wired it to my battery with 10awg wire and a 20amp fuse. I can charge my EB70s at 190watts while I drive.
wow this is almost same price as a DC to 8mm charger for a Goal Zero , bonus you have an inverter for other things as well.
Just for fun I hooked up my Victron pure sinewave 375 watt inverter to my Toyota Sienna's cig lighter and charged a raw LIFP04 pack off it with the vehicle running, and measured peak wattage output from the cig lighter at 150 watts, more than the rated/suggested 120 watts. Voltage on the cig lighter output was 14.6, so the inverter was drawing around 10 amps with the LIF04 charger I was using hooked up to it to charge the house battery. Kind of on the edge with the ratings for that circuit. I think this would be quite feasible with direct wiring from the car battery to the inverter. I didn't blow the fuse but probably close. Now to figure out how to get through the firewalll. Maybe do it this way rather than the usual DCDC type solution,as I already have the inverter and my power needs are not immense...just a bunch of 5V USB appliances and a single Dometic fridge which I usually run off the LiFPO4 house battery. This setup is probably no more than 75% efficient as the LIFP04 charger is rated at 8 amp/12V - around 100 watts. So much of that 150 is going to the inverter I guess. Nonetheless a good concept.
EXCELLENT info. Will order one today. Appears to be the answer to charging my laptop while boondocking
I’m not sure I would want it work at 11 volts. That just means it could possibly drain my battery so the car won’t start plus put unnecessary wear and tear on the battery. Not sure if pure sine wave is of benefit for a simple charger but nice to see a lower wattage inverter that has that and it seems to be a reasonable price. I wish there was a way to regulate the charging speed on my ac200p a 700 watt charger that you can adjust from 200-700 watts via software would be pretty sweet. Thanks for sharing! And yes jackeerys generally are slow to charge. . Probably good for battery life but not for real world use.
This is actually my current method of charging. I'm using an EverStart 400W and a DBPower 505wh solar generator. Using the charger that came with it lets me charge at 120 watts. No PD charging and a maximum charging rate of 150watts according to the manufacturer means I'm pretty close to maximum!
A word of warning don't use the cigarette lighter if you can help it and wire this straight to your battery. Not only does this avoid blowing a tiny fuse but I actually had my cig lighter plug itself burn out.. still need to fix that.
Either way great video, also curious it looks like just a DC-DC buck/boost converter might do the trick? My solar generator's charger charges it at 24v so matching that with 140watt output from the DC source directly seems like it would also be more efficient on my poor 80A alternator hah.
Mixed bag of comments, but thanks for mentioning not to use the cigarette lighter
I won one of these about 3 years ago so it's been out for a while and mine still works great I never thought about charging my solar generators with it though and thanks for testing to see if it was pure sine I always wondered it seemed like too good of a deal
Bought it. Thanks for the code. I was impressed.
I tried charging a Bluetti EB150 with a Bestek 300w inverter. It will not work if a 15 amp fuse is connected to the cigarette lighter or power port. It will blow the fuse as soon as the inverter is plugged into the Bluetti. Notice at 10:00 in the video that the inverter is connected directly to the battery.
What is the solution?
How did I miss this video but glad I finally found it.
This is good to know. I tried plugging a 12v car battery into my Pecron e3000, and it was weak sauce... only charged at 85-90W. My supplied charger is 600w, so I will have to find a 24v 300W charger to pair with the little Bestek.
I’ve got the Bestek 400w. I’ve been charging my Schumaker all in one battery charger for years off it. Using the dc cigarette lighter input. The Bestek will run a portable fan on it aswell as a charger.
Thanks for sharing
Can’t believe this was 4 years ago. We have come a long way.
Great video. You are right it did not charge my Jackery 240 but I'm gonna try it with my Suaoki 500. 91 watts!! yes! Thanks Tom
It came out to like 32 bucks with tax....there's a 20 off coupon on site plus the P3K code, that's a decent deal for a sine wave inverter for laptops and more sensitive electronics than just a modified sine wave.
Mark, thx for saying something as so many are just one or the other. I just ordered it & got both discounts, too: the 20% coupon off was $9.20, the P3KDY9Z8 code was $4.60 which dropped the total from $45.99 down to $32.19 (plus sales tax). 😎
Karin Hart Ditto. Sweet deal.
I’d like to see this work in an actual vehicle where the alternator and battery are at play versus this lab. I’m doubtful it will work since I’ve tried this multiple times in different vehicles with no luck. Maxoak informed me personally that they’ve never actually tested this themselves which makes their EB150 crap since you can’t charge while driving (what better time to recharge than while driving hours to next destination?). I challenge HOBOTECH to post a video of this working in a vehicle while driving.
Works great with my PowerOak PS7(MaxOak AC100) in my 2012 Citroen Jumpy.
It doesn't work. After 2hrs of driving my bluetti lost power
Your on track with this charging info posting . I look forward to looking at your other gadgets . The adjustable output with the cooling fan will certainly be enough to get me in all kinds of trouble . . . Lol . Thanks Hobo Tech
My River 2 literally melted the original 12v cord and Ecoflow replaced it with a newer one that has a thermal fuse thats totally useless. I bought a USB C charger and can get 29w input but the charger still gets warm and has shutdown a time or two. I'm typically trying to recover 34-40% and the USB-C can do that in a few hours.
Will i see the same 12v overheating issue with this unit?
I have the EcoFlow River Pro. It charges at 650 watts from a house outlet. The Kilowatt shows it is pulling 750 watts from the house outlet. I’m getting a 1200 watt Bestek inverter (hooked directly to the car battery with thick wire) so I can charge the EcoFlow in less than 2 hours 😊
The solar input is only 200watts. I have a 24 v 10a China power supply that puts 200 watts into the solar input. It works off a small inverter too. But that takes 6 to 8 hours. I want to charge the River Pro in less than two hours while I drive. The 1200 Watt inverter should do that easily.
Wish I woulda read this before I bought the Bestek…it can’t handle charging my EcoFlow River pro
You talk me to buying one of these and I am very very happy thank you.
I got a 300w inverter long before I watched your video and it's a "modified" sine wave. I'm wondering what that would look like on your readout. Guess I could research that.
Not that it matters much because it still works to charge laptops, run power tools, incandescent lights, etc. without interuption.
I've used inverters in the past that were really bad. It was easy to tell by hooking up a Dremel tool, turn it on and you could hear - and feel - it miss a beat about every other second :-)
The Bestek has a decent sine wave almost to full output. Drawbacks...it consumes 7-9 watts just by being plugged in with the inverter switched off. The USB ports are always powered up. The output voltage is 110 volts and never higher. I have several and they are reliable.
Great video, much appreciated! For charging the Bluetti EB150, would it be better/faster to use the Bestek 500W Inverter?
So don’t know what I’m doing wrong, but I have an energizer power source pro solar generator and after watching your video I purchased the Bestek 300. I plugged the 300 amp into my jeep and all my power bank does is click there’s no input wattage?
Did you get the pure sine wave version of the Bestek?
Hi. This is the closest video to answering my question. Can a 12v 100 AH lithium battery be used to extend the capacity of these power stations instead of buying the much more expensive expansion packs?
Just for everyone currently trying to use this work around for the Bluetti, the stock AC adapter outputs 210-220w. If your 12v outlets are wired with 15A fuses, you’ll only get 180w. So unfortunately, unless you can get an older AC adapter from Bluetti that outputs 170w, this will no longer work.
Thank you! I blew 2 fuses today and needed this confirmation. What did you end up doing? Are you able to buy/find an older AC adapter or just scraped this idea altogether?
@@espesp9603 I contacted Bluetti about obtaining an older AC adapter and I don’t think they understood what I was asking. There’s a bit of a language barrier with them. I’m probably just going to have a local car audio shop install a 400w pure sine inverter. They quoted around $300. I’ll wait a bit longer though in case Bluetti starts selling an appropriate car charger.
@@coreybohborey Thanks for the info and response. Yeah I’m going to wait to see if they come out with a car charger too. I am really bummed out it didn’t work. I don’t really want to do the solar panel on the roof. Plan B for me is to buy the Dokio 300 foldable solar panels for $300. I also like your idea of having a 400watt inverter installed... thanks!
Why is everyone so dead set on using the outlets in their car????
Be a man, wire up your own high amp 12V line through the firewall and position it where it is best used. All this takes is some 8 or 6 gauge wire, an inline fuse and your choice of connection to the inverter (just hardwire it)
The lab tech coat and gloves is a great selling image.
I bought that max oak eb240 with the idea that i would be able to charge it while driving.. I had every reson to believe it would work. Unfortunately its either over or under volting the eb240 causing it to momentary trip on and off... I wish i had a solution for this
Great info, looking forward to buying this and making my vanlife easier
Next paycheck buying a Hobo tech t-shirt
thank you for this!! this and a few other videos of yours has been very helpful for me. keep up the good work!!
Thanks HOBO !!!! I will get one of these today ..
That's a great inverter, thanks for review! Let's say you had a 100Ahr flooded lead acid (LA) 12V battery, used, outside of the vehicle in a tent for a week, and you didn't want to start the car or move the car for an entire week so you're not dealing with your vehicle. You had a different charge controller and solar panel that would quickly charge up the 100Ahr lLA battery. Your 1500 Bluetti is running a lot with a 12V DC fridge 55W all day in hot weather but internally it cycles on 50% of the time. When the 100Ah battery is fully charged from it's solar panels, could you use the 100Ah LA battery to charge your 1500 Bluetti in a DC to DC charger? that is, NOT using an inverter to convert it to AC? I alrady asked RichCell chat and they said no. Why isn't there something like a 12vDC to 12V DC charger, to go from LA to Lithium battery? We jump start vehicles, why can't we do this? Thanks much,
I am driving a Sienna hybrid van. Would I do the same thing as with a regular car?
And what a difference a year makes!
No excuse for no 100-120w 12v charging.
Nice one Tom 👍
AWESOME! Ordered it! Thanks professor! Learning something with every post!
I’ve got 2 gauge five foot cables straight off the battery, connected to my 2000w inverter I only use it while running. Been running strong
wish you would have really close up showed exactieally how the connections were done to the battery dang it....that was what I needed to see
Same as jumper cables
Higher power inverters like this Bestek 300w, with a cigarette lighter plug, are a blown fuse waiting to happen. Most powerports/cigarette lighter sockets in most cars are rated at 10 amps or 120 watts. This will blow the fuse at less than half the rated capacity of this inverter. Personally, I would not use this connected to a power port unless you know for a fact that the port is rated for at least 300 watts. Also, this will put additional load on your alternator so make sure it can handle it. Charging high power items off your vehicle can be tricky. Make sure you do your homework before you start hooking stuff up.
Sorry, but I MUST question this. My 2013 Ram cargo van has a 160 A alternator & 730 A battery. Granted, the cigarette lighter socket may not handle all that, but I don't see why they would put a low amp socket out on a 160 A alternator.
This Bestek 300W has an on-off and a failure light---fail-safe, fuse not needed.
The AC charger that comes with the EB240 Bluetti, is now rated:
In- 120 volts AC at 2.5 A (300 Watts - a match)
Out- 42 Volts DC at 5 A
(210 Watts- Well within the 68 Volt, 10A max in to charge the Bluetti)
(but faster than the lower wattage charger that the EB240 originally came with)
BTW, you need this setup to charge from the car because the 12 volts from the car is UNREGULATED and can vary from 11 Volts to 13.9 volts.
The Bestek Pure Sine Wave inverter takes care of that flaky voltage.
I just plugged it into a new 2020 Ford Transit 12v plug and tried to charge my Bluetti and it blew the fuse.
@@bundokin9858 You bought a TRANSIT?
seriously, what size alt, battery, heavy duty solenoid?
Professor, I am contemplating this idea and ask for your scrutiny:
I like to have a 1800 watt power station but no solar panels and I will fast charge with the AC output of a large pure sine wave inverter while I am driving (will have breaker and a battery isolator).
The mini-van alternator can max out at 150 amps (higher if I need to put on a larger/180 or 200 alternator).
The power station is the EF ECOFLOW Portable Power Station DELTA, UPS Power Supply 1260Wh Battery Pack with 1800W (3300W Surge) AC Outlets. It has a fast charing capability when plugged into 110 V AC and the manufacturer advise that that will take about 3-4 hr. BUT the inverter output must be 1500 watts or higher like 1800 or 2000 watts. I think I can find a inverter of that spec.
The idea is that I will drive 3 or 4 hours a day and can survive most of the days with this scheme.
EXCELLENT presentation. Very clear and easy to understand. Thank you
Master Jedi hobo you are awesome the force is strong with you
Thank you, Tom. Just got it for $28! A 20% discount from Amazon AND your discount code. Also had $5 credit in my acct - worked great! Will be handy to charge my J500 when can’t use my solar. I truly appreciate your reviews and especially the full explanations. Thanks
Hi HOBO,
I tried the same thing to charge the EB240. When I plugged the Bestek inverter into the cigarette lighter while the engine was running, the EB240 charged at ~210W. After 2 minutes the cigarette lighter fuse blew and stopped working. The cigarette lighter fuse is 20 amp.
If I connect the inverter directly to the engine battery to draw >210W of power; will it work?
Is it safe to permanently hookup the wires to the battery terminals and use the inverter to charge while driving? Will this damage my engine batteries in the long run?
Can you provide some recommendations on how to safely draw more than 200W from the battery? And what is the max Wattage that can be drawn from the battery continuously as long as the engine is running?
Chuckle I travelled with my big Tom ..solo in a caravan cats really adapt well don’t they ...thanks for the power vids I’ve built my own power box and the inverter is the last leg for it. I’m using a ver old ring power can but could do with a slightly more able one to run a old notebook that I’ve swapped to Linux. That move alone dropped my consumption as it seems to leave windows well in the rear mirror strain wise on the battery. Love the approach. You need a igor assistant
Can I do this with a delta ecoflow 1300? It claims you can go from 0-80% in 1!hr as opposed so 5 hr using the 12 volt charger so this would be fantastic. Also would I need to put a larger fuse in my car charger and could this be harmful to it?
No. Only works up to about 250w. Even then I'd only push 200w through.
I have the same issue, I am thinking about getting a older laptop charger and putting on a XT60 female plug, this way I can use a smaller 800 watt inverter generator to charge it. Just make sure that the output voltage is correct and you have the polarity correct, Negative to negative and positive to positive. You would only be able to charge at about 100 to 120 watts depending on the charger you find, Goodwill usually has some of them for just a few dollars each. This would then plug into the DC input on the delta flow
I was educated, and I liked it. Thank you.
Great Solution, I have a Blueetti/PowrOak PS10 -2400 wh. It charges at 210 Watt.
If i would put the inverter between the car battery and the powerbank and let it charges whilst driving, would this not drain the battery of the car aswell ?
I have no idea how much Watt the alternator charges the car-battery.
in short...car cigarette sockes are fused at 10 or sometimes 15A at 12V, (=120-180W) but some power stations limit theirr 12V DC input even lower to only 8A (=96W). So yes, if you are lucky to have a car lighter socket which is fused at 15A then you can nearly double your charge rate with a device like this to a still fairly low max 180W. But if you have the car socket fused at 10A then you have only minor gains. Also dont try to swap fuses as that is super risky for overloaded wirings burning down your car. Plus, you are basically inverting/converting twice, once from DC car to AC inverter and again inside your powerstatoin back to DC to charge the battery. There are more efficient/faster ways like using a DC DC converter hooked up to the car alternator together with a cutoff relais, which can basically charge powerstations through their solar input theoretically to their max possible W (example ecoflow delta 2 at max 500W)
@HOBOTECH Perhaps charging a solar generator is a good use of the old Modified Sine Wave (MSW) generator many of us have kicking around. In fact, you could create a Pure Sine Wave (PSW) inverter by connecting 12V -> MSW Inverter -> PSW Solar Generator -> Load
The Titan has me interested waiting to find some in depth reviews mainly for the bigger inverter
Thank you, you are a great resource. Just ordered one for my new EB240.
Excellent information . Also you have great taste in eyeglass frames🤓
I bought this for my Bluetti EB150 to charge in my 4Runner while driving but no luck. The AC wall charger kept toggling on and off. Eventually the 15 amp fuse popped. I can charge in the 4Runner with engine running using the onboard 110 but that turns off once the transmission is in drive. I can't believe the Bluetti cannot be charged in the car while driving. This is a major con and I now regret buying one. I love this channel though!
I ordered the Bestek 300 watt to charge my Jackery 1000 from my 2015 Prius Hybrid. I tried the aux outlet and it worked great for 3 days. ( With engine running. ) Then the fuse blew. I replaced the fuse and it ran awhile and blew again. I didn't have any more fuses so I tried it in the cigarette lighter. That blew the fuse too. The Toyota uses 15 amp micro short fuses. I ordered 2 packages from Amazon and replaced both fuses and now neither my cigarette outlet or auxiliary outlet will work! I thought maybe the fuses might be bad, but I tried several different new fuses and nothing! I am afraid I must have fried something. I was only pulling about 165 watts while charging the Jackery. I don't see that the fuses are blown and I don't see anything burnt in the outlets.
All my vehicles have an inverter. The inverter transmit 120 volt power through 14 gauge extension cord and to my camping trailer. Then I have a standard dc battery charger charging my camper batteries. I can charge upto max power of inverters. I do not need any fancing welding cable to charge my camper battery. The batteries are always properly charged to correct voltage . Bonus they last 10 years plus. As I only discharge to 50%.
Wow..The inventors are really coming out with cool gadgets in the electro world..Now if they can get the cost down on a ;lot of them,that will be great.. enjoy your day..err night
I tried using this with the ecoflow delta using the cigarette lighter in my Suburban but no dice. It powered up but the delta just clicked a few times and went into overload.
Any suggestions?
same. any luck?
Same. Did you guys figure this out with your Delta yet?
Mine keeps cycling back to zero watts charging every 4 or 5 seconds. It charges better plugged directly in to lighter socket without the inverter.
How do we determine if this is too much for our car's alternator, I have a 2014 Honda Odyssey?
Also I see there's a 500-watt version of this is this too much for the van?
