George: I appreciate your concern and trust me, the other pilots and I do not take the forming of Voltron, or it's powers, lightly. That said, we have gotten pretty good with our control and our collateral damage statistics are way down as of late. You have nothing to fear. Thank you for watching citizen.
This panel can put out close to 100 watts ua-cam.com/users/postUgkxOqI2yqX0XVrhR2BMJciTWrHJpG8FhJyg when positioned in the appropriate southernly direction, tilted to the optimal angle for your latitude/date, and connected to a higher capacity device than a 500. The built in kickstand angle is a fixed at 50 degrees. Up to 20% more power can be output by selecting the actual date and latitude optimal angle.The 500 will only input 3.5A maximum at 18 volts for 63 watts. Some of the excess power from the panel can be fed into a USB battery bank, charged directly from the panel while also charging a 500. This will allow you to harvest as much as 63 + 15 = 78 watts.If this panel is used to charge a larger device, such as the power station, then its full output potential can be realized.
It has four 1.5W solar cells, so in total a 6W solar panel, which means in reality it gets about 5W under optimal conditions. The battery is 96 Wh, so it should take around 20 hrs of direct sunlight to charge fully. In the US on average you get about 5 sun hours per day, so it should take 4 days to charge, but being overcast/sub-optimal conditions might push that to 5-6 days which is in line with your findings. But that's to fully charge the battery. To get ~13 Wh which is the average cell phone battery size should be doable in one day or at least get 80% if it's overcast, and that's not too shabby for how big the thing is. Also, putting a solar panel behind a (clean) window reduces efficiency by 50%, even worse if it's double pane or a tinted windshield. It also reduces how much direct sunlight can reach it throughout the day, especially if you're not putting it right up against the window, so that's why you hardly got anything with that approach. I think this is a very cool product, but in reality you wouldn't use the solar 99% of the time when you're near civilization, yet it adds 30% more thickness and some weight. If you go camping or expect to be away from outlets, then you can buy a separate portable panel like the 21W Anker or 28W Big Blue which will give you a lot more power. So it makes more sense to get a regular power bank and just bring those portable panels with you when you think you might need them.
Thanks for sharing that information and your thoughts. Your idea about using separate portable panels is sound but they can be a bit more expensive (BigBlue for example is going for $63 on Amazon) and they don't have the added functionality of the power bank for stored charge. What's nice about this product is you can leave the power bank behind to charge while taking your phone with you. Don't get me wrong, I love the idea of using separate solar panels as well. I just think both products are better suited for certain situations. Thanks for watching!
Great post. Re: separate portal panels, since this is the same price as a similar sized power bank, I would just get this AND hook up the other panels for extra juice. Win-win right there I think.
So I can buy a separate tunnel to hook up to the battery charger how does it connect through a USB C any recommendations would help what's your recommendation for the best solar charger that also has a plug for plugging in things like appliances I can be a little more expensive like under 200 I think I was looking at something called the lion cub go but seems like there plug-in had some problems I don't know if they fixed it or not
@@unbroken1010 usually the small fold up panels have their own connectors on the side of the power bank. For the larger panels you plug them into the input usb-c or micro-usb on the bottom of the power bank. I suspect most banks will allow simultaneous charging from the 2 input sources.
People seem to forget that it's not only phones that can be charged off of these things in a bug out scenario you can charge weapon lights or regular flashlights radios all sorts of other equipment I even have a USB chargeable lighter that is excellent for starting fires. It's basically just a coil with induction heating but it's a renewable resource that I can continue charging up off of one of these things and not rely on lighter fluid or bow drills or anything else. You can't expect wall power off of a couple tiny solar panels so I think a lot of negative reviews come from people who aren't realistic in their expectations. If you have a lot of your equipment that runs off the same 18650 batteries or other rechargable batteries and you have a USB charger, you can continue using that equipment long after the power grid goes down and generators run out of fuel. Most of the stuff that plugs into your wall is just a box with a step down transformer that usually bumps it down to 12 or less or 5 or less volts and basically anything that is going to be running in the 5 or less volts can be USB chargeable.
Nate: I think you hit the nail on the head about expectations, and if the grid ever did go down it's a heck of a lot better to have something like this than nothing at all. And while the technology is far from perfect it's not really that expensive. I am definitely willing to pay a couple of extra dollars for the added functionality. Thanks for your thoughts and thanks for watching!
I've owned at least half a dozen power banks and I was always interested in the solar. I bought one that had 5 total panels and here's my $.02. They will NOT charge under indoor lighting so don't try. Also don't try and charge them indoors next to a window like this guy did. They need full direct sunlight and a lot of it. They are a doomsday device only and not intended for everyday use. I bought one for my daughter's bug out bag.Great for camping and such but not for the power hogs.
Wing: I agree with most of your points. Outdoor charging is definitely the way to go if you are trying to make use of the solar panels, but don't forget if you are a power hog you can always just charge it with a cord. Thank you for sharing your thoughts and thanks for watching.
No Go only worship music. But the government won’t be tracking me down. Vaccines/mark of the beast have quantum dot tattoo, that will track you and track who has been vaccinated. They will use your phones too. They are already building camps just like the Holocaust. Go look up fema camps. We are in the end times, going to be a time when you leave everything and go into the woods or follow Jesus Christ
@@letsprayandfasttogether9618 well they do track you by your phone location, buuut that was possible a long time ago. also quantum dot? i know you are pretending to be delirious but uhh... no.
Because solar panels generates electricity from UV (not necessarily sun light) when you tried to charge the power bank from indoor, behind the window, most of UV where blocked by the double glazed window... that's why it did not charge!
Thank you, Rando, for this video. Really well done and I was able to understand all. It seems this type of device is just made for my aim: long-distance cycle touring when sometimes I can stay at some organized camping ground and some time at wild camping sites. So it permits to maintain the power bank at least partially recharged while traveling between two AC provided sites.
Thanks Dmitry. I'm glad you found the video useful. I feel like your use case is really what these type of products are designed for. Take care and happy cycling!
I have the same one in your video and it works well if it's in full sun and is maximized. Something to keep in mind is that most glass has UV protection and will stop or reduce charging of any solar device.
I believe I have this same model, but it is only one part of my portable / backup power solution. I almost never use its attached panels (maybe good for 5W); instead I connect it through an adapter to the same much larger solar panel (100W-200W) that charges a portable power station. This device can charge my phone, UV-5R, razor, and other USB devices, plus charge NiMH and Li-ion batteries; the portable power station can run a compressor-cooler, charge tool batteries, and run other larger lights and appliances.
Good no-nonsense video. I have the AddAcc version, (7.5W) coupled with an Anker 21W panel that connects into it via the microUSB. As most powerbank batteries are 18W I’m pretty sure it’s not getting the full 28.5W I could potentially be capturing, but between its own 5 cells and the large Anker cells I can charge the whole thing from flat to full in about 9hrs. I’m lucky to get a full day of direct sun as I face south and am on the south coast of the UK so have slightly less cloud than the rest of the country. Today I’ve just used the Anker panel on its own to charge a separate 21500mA power bank from 0 to 75% in 5.5hrs. With the power I collect in the AddAcc solar bank and the separate Ravpower bank I charge my phone, iPad Pro, Apple Watch and air pods overnight where necessary and have essentially removed all of the devices I use all day for work from the ‘grid’. They’re all super-low power devices I know, but it’s a start. Any power left in the AddAcc gets used to top up the Ravpower bank and then it goes back outside first thing in the morning. I carry the Anker panel with me too so I can charge power banks in the car (laid across the dashboard), at work (works well in a window, unlike the AddAcc unit, we also have a roof terrace I can use) or even on the beach. If Anker can produce a battery unit that fits in their large 21.5W panel and has a digital readout displaying charge percentage and power input/output then I’d be absolutely all-in.
Ben: Wow. I admire your commitment to this. I have flirted with getting some panels. I think if I'm going to get serious about solar that will be my next step. Thank you for sharing and for watching!
Hi, did you do the recommended first charge for 5-6 hours using regular electricity? That's what some of them say to do. It might have affected your results. Thanks for the video. It's always good to know how different settings affect a product.
Never put these in direct sunlight over 85 degrees. I've had 4 of these with different options. I made the mistake with my first one. The unit swelled and was on the verge of exploding. I believe many of the manufacturers recommend indirect light for charging.
Allen: Wow. That's crazy. I have charged my power Banks in heat well over 85° many times and I have never had something like that happen. I guess I'm lucky. Thank you so much for sharing your experience with us and thanks for watching!
@@RandoTechInfo yeah I've replace three batteries now in my power banks. Then my cell phone battery just recently swelled from direct sun. Split the phone in half. I had to rebuild it. You have definitely been lucky. Hope that luck keeps up for you.
I picked up a single panel solar power bank. My purpose is a little different. People in our group each picked up a single panel one so we can go an entire day without having to use another power bank. The solar keeps the power bank topped up with trickle charge solar the entire day. It lasted me and my friend the entire day. We were doing pokemon go the entire day in the summer for an in game event
YES!!! You Sir, won a subscriber. I was searching for a detailed video and this is the best I have found. After a strong snowstorm and NO power for several days, I really appreciate this very well explained video. Thank you.
I have the single panel version an got to say it let me down big time, I spent 8 nights out in a heat wave. Took it out fully charged it worked for 1 an a half days. An that was it it was literally in direct 20 odd degrees of beaming sunshine an maybe got 2% out of it. It doesn't look broke or there are no lights to signal that its broke.
No banks that I currently know of can charge fast enough to keep up with steady use. For that you would need larger panels. The technology is certainly still far from perfect. Hopefully in the next few years solar panel efficiency will improve. Time will tell. Thanks for sharing.
No you have to have a proper external solar panel with more wattage then Total wattage capacity of the battery inorder to charge said battery efficiently. Solar power is important but dose not and can not replace the grid. You are better off to wait for hydrogen generators which will be very expensive but more realistic then replacement for fossil fuels.
It's best to have the panels at an angle to face the sun rather than having it lay flat on a windowsill or table, this enables the panels to collect more sun.
I've used one of those for the last two years of full time boondocking. It's come in handy as a backup to my solar system but it doesn't really charge up all that fast, maybe one full phone's worth when angled toward the sun on the longest day of the year in the desert. Recently the battery started to fail such that it would take forever to charge and then it would discharge far to quickly. Over all they're gimmicks and not meant for regular use.
Not Friend Eater: I think it's a little bit harsh to call it a gimmick but I agree you would not want to use the solar panels for consistent, fast charging. I also agree it would probably work best in the desert. Perhaps I will take a drive and do another review. 😆 Thanks for watching!
I'm sorry, I'm really confused. You laid it out each midday giving you three hours of light in the summer + guessed 8 days would make it an accumulated 24 hours total to charge? :S also I didn't see if you tests whether the quoted mah was correct? I tried watching it a few times :s thanks for sharing
I have a regular Power bank which works very well with any phone. However, i would'nt recommend a solar power bank as this device could take your phone a couple of days to charge while a Regular power bank only takes a day to fully Charge your device. Just a thought.
Wagema: I would agree except you can use a solar power bank the same way as a traditional power bank. It will change with a cord. The solar panels just give it some versatility (at the cost of a little extra bulk.) Thanks for watching!
This solar powerbank is like the Poweradd power bank with 4 panels. It weighs a pound. I left it by the window in direct sunlight here in California, so you can imagine how much sun that is. I planned to leave it for a week to see if it will fully charge since the instructions says 50 hrs of sunlight to fully charge it. Before this, I charged this a few times using a wall charger and used it. It worked as it should. It still had 2 bars in it when I tried to solar charging. The indicator showed it charging when the sunlight hit the panels. Then I totally forgot about it. Over 3 weeks later, I remembered to check it and the charge went up to 3 bars. 3 weeks to up the charge to 3 bars from 2. Blah.
I'm actually surprised you got that much charge out of it. I have never been able to get any charge when trying to charge inside through a window. Thanks for sharing.
@@RandoTechInfo Thanks for making that comment re charging through a window. I have an older solar charger (POWER NEWS 300000 mAh capacity that I purchased several years ago and then never used really. I have had it sitting in my window for a couple of years and every now and then I see if it will charge my phone - it never does. I thought I had a bad unit, but your comments make me think like it may work but really needs to be in the direct sun (for solar charging). Thank you.
Hi Randy. I purchased this exact device last week. It is June and we have had some very sunny days. I left the solar charger opened in the direct sunlight for three days. The charger started at two lights and by the end of the three days, it was still at two lights. The device appears to work in every other way apart from charging up in the sun. The device was flashing indicating it was charging. Do you think it is faulty or was 20 hours of direct sun not enough to raise the indicator by one light? I suppose it could have gone from 50% up to 74% and the light not change up to three lights. If these devices had a better way of showing how charged up they were then you would know how much charge is accumulated in the time that you left it rather than thinking the thing is broken. Any feedback would be welcome.
Charles: I totally agree with you about the light situation. The lack of a numeric readout is an issue. On my unit the lights flash sequentially while it is solar charging. Is yours doing the same thing? If it's not, I would say you have a defective unit, if the lights are flashing sequentially then maybe give it another day or two. That's my advice for what it's worth. Please update me on your situation if you figure anything out. Thanks.
I had gotten a 21w big blue solar charger and it almost fully charges my phone in 30 min. I have an iPhone 8 plus and it can charge a power can't alongside with the phone. Much better than the feob solar power bank which is similar to the one your testing.
I charge my 15000mah battery bank with an xdragon 20w solar panel in 4-6 hours depending on the sun. This is in Denmark, where the sun dont shine all that much compared to some placed in America. I'm pretty happy with that amount of free power. Keeps my phones and stuff charged up.
i was planning on getting something like this because im going to camping in the woods for 2 weeks straight (army/military service) but then again its most likely gonna be cloudy all the time, its cold like -10 to -20 celcius and in the woods probably wont really charge the powerbank at all. So i think it just means no phone after my other powerbanks go empty with ultra power saving mode maybe in a week.
Mr Tordse: Those temps are gonna kill any and all batteries and power banks. In the scenario you will be in, I'm not sure how helpful the solar functionality will be. If you are out there for two weeks you might get a LITTLE extra juice from the solar but I certainly would not count on it. Thank you for your service and good luck out there.
Seems like one would only fully charge this once. If hoping to use when power is out it's extra panels are really of no use after the first time because it would be being used daily not once every 8 days to let it charge to full again.
tahaji: What you are saying is not wrong, but I also think the scenario you present is not the product's intended use. You would not want to use this as an only source of power for an extended period of time. (You are correct that would clearly not work.) It is simply a way to get some additional/free power when away from home or an outlet for a few days. To use your example, if you lost power, and were able to get some solar charge, you might get an extra couple of days out of it, as opposed to a battery that had no panels. Solar energy is not in place yet to replace a lot of major power needs, but I do think the supplemental power it provides can be useful in the right circumstances. Thanks for taking the time to share your thoughts and thanks for watching.
Not only will a NON-USBC connection take longer to charge, it will fail in 9 months to a year with normal use!! I'm living proof with 2 Doss bluetooth speakers which are effectively Earth-polluting bricks, smh.
mAh in batteries are not equivalent ratings. You have to convert to Wh first to make them a direct comparison. On top that you won’t achieve 100% efficiency of transfer. 4000mAh in battery will not fully charge a 4000mAh device even if same voltage. You will lose power to heat and electrical resistance. I’d like you to charge your phone fully and watch that battery go down 30-40% and make a new video explaining that portable charger would take multiple days to generate the energy to charge a phone. You would need several of them to make regular use of the device if only using solar power.
USB 2.1 Amp is slow and outdated. It will not be good enough to charge my note 20 ultra. My phone requires 3.1 Amp to charge it. I opted for the 40000 mili Amp power bank
What i have found is, the solar in my Power bank is for emergency charging. It will give enough charge for the flashlight to work for a bit. My bigger one, might get my phone charged enough for a call? . My hand cracked solar charger only works the radio and flashlight. You have to precharge the (10k mah battery) to charge a phone. . Bigger the solar panel, the better the charge 🫵
I bought the 43800mAh solar power bank and it only charges to around 4000mAh. Just get a well recognized brand power bank and not those chinese solar ones from Amazon.
When the hurricane is over & you have no electricity, for days- Im thinking something (if charged) is much better than having- nothing, so if you have an emergency call to make, they seem fine.
I honestly think the test should happen a different way like the solar panels are meant to charge the phone tablet etc during the day and battery operated during downtime from the sun like cloud coverage maybe for a few seconds then at night when you have no sun I think why it charges the actual device slowly is because two things one if you’re not using the solar panels to charge a device then the power goes into the batteries two you have lithium ion batteries in direct sunlight and when batteries is being charged it warms up also the sun’s rays heat up the batteries honestly I just think it’s a design thing as a safety feature for the device and to conserve battery life for when you don’t have sunlight just my thoughts
I think it’s good to have as a back up. May take days to charge but 4 days is not bad as if your only using to say charge your cell phone it will do the job. Good just to have you never know get it why it’s cheap before china stops trades lol 😂
It’s crazy that these things take weeks and sometimes months just to get a bar of charge from these things. Sometimes they don’t charge at all. I don’t even know why they call it solar power chargers Lol. My outside Solar lamps charge faster than these things. And they have to nerve to charge $20-$100s for them
I'm actually putting the finishing touches on a video where I test 28 watt solar panels. (The solar panels on the power bank from this video total 6 watts.) I think you might find it to be a better solution. Thank you for watching!
Keeping them in a window is a good way to ruin the device completely. It will never take a charge and only stress the batteries out and eventually they will start to expand and not hold charge at all
I will be getting a few of these. I am also interested in a Bluetti battery bank but they are very expensive.. i will also doing reviews on the solar chargers
I just got my "winlove" branded solar power bank. It looks identical to yours, except the red trim bits. I'm looking forward to playing with it. If a person is relying on the solar to keep their devices running, a minimum use strategy on the devices will help extend battery life and these small solar panels may be more viable. Just a thought.
"Do Solar Power Banks Really Work?" Mine doesn't! My Li-polymer 18000mAH 5v power bank should be equally chargeable from its built-in solar panel or from USB. It charges OK from USB, but sunshine causes it to discharge instead of charge. Blue LEDs correctly indicate presence of sunshine on its solar panel, but this sunshine causes battery to go down instead of up. I can only suspect internal wiring between solar and battery must have reversed polarity somewhere. I seek guidance on how to correct this
Thanks for taking the time to perform the test and sharing it. I guess the answer is no. If it takes days to charge a bank, that's terrible and completely not practical for any sort of usage. It seems like it would make more sense to charge the phone or devices directly through a solar panel vs taking 6 days to charge a bank and then another hour to charge the phone/device.
I can’t find one that actually uses sun . The solar panels are fake on the one I bought abd every other one I research . Is there a single one on the market that actually uses the sun to recharge or is it all just bullshxt? Edit: So this one does, just slowly?
Juan: I have never run into and "fake" solar chargers. Where are you buying from so I make sure I don't shop there. In any case yes, the panels on the bank in the video do indeed work. Thanks for watching!
Seems like all the 4 panel charges take a week in optimal conditions with full day charging. Single panel chargers take a minimum of 2 weeks. You would be done with your camping trip, hike, or rescued by time these things charge. smh Great video, ty, but I think I'll pass on these devices. I wanted one for the SHTF scenario. If SHTF you're probably always on the go, so this may not be a good purchase. Originally I was thinking just velcro it to a backpack with the panel facing upward and let it charge. I don't think it's gonna work. Then again my Bday is coming up, so maybe I should post on FB a link and Bday coming soon msg, and hopefully get lucky. lol
It's funny, we used to have to figure out ways to drop hints to people to get what we wanted for our birthdays now we can just post them online. 😁 I did do a review a couple of months ago on some 28 watt solar panels that might suit your needs a little batter. Thanks for watching!
Rokas: I wouldn't try to charge a car battery with it but it should be able to charge any type of portable device, like a tablet or headphones, just fine.
Great Video! Thanks! I took cheap solar bank 1 panel replaced original battery because it got puffy with some old 3.7 phone batteries 2 of them run in parallel. And works well for what it is. And found the cell phone batteriez do better in heat! Thanks and good Luck!
I wish I had seen this before I bought one from "my Patriot Supply". Not only did it cost WAY MORE but its detective and they won't pay my return postage. Please stay honest so people like me will still trust. By the way, it recently got marked down to half. Wonder why?
Cheryl: Not familiar with "my Patriot Supply" so I'm glad to get some info. The charger is no longer sold on Amazon either. The one from the video still works but I have a LOT of power banks so no particular one gets too much use anymore. Thank you for taking the time to share with us and thanks for watching.
6 days to charge 75%. 8 days to charge fully. It's definitely not going to break any speed records but remember this is a huge battery. A smaller battery would obviously charge to capacity much faster. You can also just charge via the wall when available. Thanks for your thoughts and thanks for watching!
if you consider that in greece we have your kind of sunshine at least 50 times more it would be logical to assume the powerbank would charge in a days time !?
I don't think so. Even with MAX sun, I'm guessing it would take multiple days to charge. If you do pick one up though, come back and let us know how long it takes to fill up. I'm curious.
@@RandoTechInfo well I tested the mah capacity with a usb tester and it said 17,003 mah, although it will likely go up over the next few charge cycles. Not sure exactly what to expect there but I'll let you know if you'd like.
Lol, I bought this just to keep from using power adapters, and saving energy. With a fully charged 25,000 mAH battery, I'll be able to charge my iPhone XS up 9 times, which literally means 8-12 days of use without a power outlet! Not bad, and it would definitely come in handy if a bad storm or tornado came threw and knocked out the power for a couple of days (like it did last year during Easter). Worst case scenario, if I forgot to charge the power bank up, I can just open the panels up and put it on my car's roof and charge my phone that way.
Thanks for the useful info. Has anyone ever told you that you look a little like the comedian Jim Breuer? You've got those slightly "stoner eyes" too, lol. That's a good thing, btw. ;-)
Forget that! Buy a regular powerbank and get a 10-20 watt solar panel that is usb compatible. I just charged my nitecore 14000mah power bank in about 2 days. ...but then again I'm in Texas lol.
Hey john. I'm actually going to be putting out a video here soon where I test some 28W panels. Hopefully we get some promising results. Thanks for sharing your thoughts.
Can someone help me out. I have a feob solar charger with 3 external panels. When I put this device in the sun. When I don’t have the external panels attached it indicates it’s charging but when I connect the external panels the light turns off and it won’t indicate it’s charging. How do i fix this?
Well the instructions do say not to depend on the solar system for "phone ;) " charging but that it's there in case of in a emergency when you have no way to charge your device. So one would not or should not have to wait many days for a full charge but to get just enough power to be make a short call vs not being able to make any calls at all with a dead phone.
Forgot to mention in black outs the led lights last a hell of a long time also the usb can power a 12v usb fan when the AirCon or outlet fans have no power to cool you off. You would be good with light and a breeze to spare :) People may be like oh I'll just use the led light on my phone, but it's dead with all the social media stuff and calls one did all day long. So in a situation like that we pull out the "brick"
Puchi: All good points. I see it the solar charging capabilities as a back up or an additional way to charge, not something to use on the daily. Thanks for sharing your thoughts and thanks for watching!
I wonder how many phone charged it would take to recoup the initial cost of the device itself. I like the idea of solar to save money but not sure if this would save me money. Hmmm
I do not feel like it is necessarily a money saver. The solar charging just isn't quite fast enough for that. I just feel like the solar panels add some nice utility for not a lot of EXTRA money, if that makes sense.
I bought one of these but it will not charge by the solar panels. I discharged it by charging my tablet 3 times and my phone twice. Then I put it out in the sun for 7 hours 3 days in a row, and there was only 1 blue LED lit. Piece of crap.
@@RandoTechInfo -- It's the same item. It charges great from an AC to DC adapter, but not from the solar panels. The 3 removable panels attach via a magnet and are eletrically connected to the battery pack via 2 pin connectors. I wrote it off to the fact that the Chinese having no Quality Control. I may take some of my federal stimulus money and buy another unit. I waited too long to return it. I really want a solar--charged battery pack in case I lose electricity to my house for an extended period of time.
Cool video. In your opinion what is the best top 5 solar banks on the market? Is there a practical option between 200 to 700 dollars or will I be getting junk? I'm new to this type of device but looking for a good device for emergencies? Thanks buddy.
Pops: Not sure about a top 5, I can give you a top 2 though. I do really like the power bank I used for this video. It still works like new and the fact that the "extra" three panels are detachable is a really nice feature. (And something I didn't mention in the video.) Here is the Amazon link: www.amazon.com/gp/product/B07V2CQVV3/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 A less expensive, but still really good choice, is the Tranmix Solar Power Bank. It's missing a USB-C charge port and the extra panels are not removable but for under $30 it's a nice value option. I did a full review of this one if you want to check it out. Here is the Amazon link: www.amazon.com/Charger-25000mAh-Tranmix-Waterproof-External/dp/B07W54NM91/ref=sr_1_4?dchild=1&keywords=tranmix+solar+power+bank&qid=1611416606&s=electronics&sr=1-4 Hope that helps. Thanks for watching!
Your maths is wrong with the lights i think. 4 lights is not 100% it is i above about 80% that is why the fourth light doesn't turn off the moment you plug a device in to charge and the battery bank drops to 99%. So 6 days in full sun probably charged it to somewhere closer to 80%
Hey I’m in the market for one of these solar power banks but I’m sketched by all the fake ones on Amazon, do you recommend any with a legitimate high capacity mIlliamp hour rating?
Power bank I used in the video is no longer available and I'm not really sure what's all available out there right now. I know a lot of people like Blavor. Perhaps start there.
In short, I believe they do work. No they dont charge your phone as fast as a regular charger but they have good battery and a led light. Plus some of them are even waterproof and drop proof. I have a 4patriots one and I love it.
You're actually better off getting a single cell power bank and a separate 30 watt 12x8 solar panel charger. On a sunny day you can charge this in a few hours.
Yikes this video was a mess. But hey least you showed everything including the flaws in the video. Like not knowing the product by not knowing how to turn the light on. Then testing it indoors from a window. We all make mistakes and learn from them
The heat from direct sunlight would destroy and degrade the battery significantly. Solar powerbanks are extremely slow because of the small surface area of the panels and is inefficient.
No. Indoor lighting will not charge it. The cable is for attaching the bank to whatever device you want to charge. Let me know if you have any other questions.

I'm very glad you did not have to form voltron because frankly I'm not sure you would know just how to control it's path of destruction.
George: I appreciate your concern and trust me, the other pilots and I do not take the forming of Voltron, or it's powers, lightly. That said, we have gotten pretty good with our control and our collateral damage statistics are way down as of late. You have nothing to fear. Thank you for watching citizen.
Lol
Same here. This dudes awesome.
@@RandoTechInfo what’s the link for the power bank?
What's Form volton?
This panel can put out close to 100 watts ua-cam.com/users/postUgkxOqI2yqX0XVrhR2BMJciTWrHJpG8FhJyg when positioned in the appropriate southernly direction, tilted to the optimal angle for your latitude/date, and connected to a higher capacity device than a 500. The built in kickstand angle is a fixed at 50 degrees. Up to 20% more power can be output by selecting the actual date and latitude optimal angle.The 500 will only input 3.5A maximum at 18 volts for 63 watts. Some of the excess power from the panel can be fed into a USB battery bank, charged directly from the panel while also charging a 500. This will allow you to harvest as much as 63 + 15 = 78 watts.If this panel is used to charge a larger device, such as the power station, then its full output potential can be realized.
I hope you like it.
And on the seventh day the power bank rested... and it was good.
😆👍
For some reason your picture makes that funnier lol
Lmao 🤣 😂
So it rested like God 🤔?! 😂😂😂
This is, like, the only helpful video on all of UA-cam that I could find regarding solar power banks. Thanks!
GG: Happy to help. Thanks for watching!
it takes 8 hours to charge, Not worth
It has four 1.5W solar cells, so in total a 6W solar panel, which means in reality it gets about 5W under optimal conditions. The battery is 96 Wh, so it should take around 20 hrs of direct sunlight to charge fully. In the US on average you get about 5 sun hours per day, so it should take 4 days to charge, but being overcast/sub-optimal conditions might push that to 5-6 days which is in line with your findings.
But that's to fully charge the battery. To get ~13 Wh which is the average cell phone battery size should be doable in one day or at least get 80% if it's overcast, and that's not too shabby for how big the thing is. Also, putting a solar panel behind a (clean) window reduces efficiency by 50%, even worse if it's double pane or a tinted windshield. It also reduces how much direct sunlight can reach it throughout the day, especially if you're not putting it right up against the window, so that's why you hardly got anything with that approach.
I think this is a very cool product, but in reality you wouldn't use the solar 99% of the time when you're near civilization, yet it adds 30% more thickness and some weight. If you go camping or expect to be away from outlets, then you can buy a separate portable panel like the 21W Anker or 28W Big Blue which will give you a lot more power. So it makes more sense to get a regular power bank and just bring those portable panels with you when you think you might need them.
Thanks for sharing that information and your thoughts.
Your idea about using separate portable panels is sound but they can be a bit more expensive (BigBlue for example is going for $63 on Amazon) and they don't have the added functionality of the power bank for stored charge. What's nice about this product is you can leave the power bank behind to charge while taking your phone with you.
Don't get me wrong, I love the idea of using separate solar panels as well. I just think both products are better suited for certain situations.
Thanks for watching!
Great post. Re: separate portal panels, since this is the same price as a similar sized power bank, I would just get this AND hook up the other panels for extra juice. Win-win right there I think.
@@drzoidberg1 but how would you connect the panels to the power bank do they make panels that attach through USB C can you make any recommendations
So I can buy a separate tunnel to hook up to the battery charger how does it connect through a USB C any recommendations would help what's your recommendation for the best solar charger that also has a plug for plugging in things like appliances I can be a little more expensive like under 200 I think I was looking at something called the lion cub go but seems like there plug-in had some problems I don't know if they fixed it or not
@@unbroken1010 usually the small fold up panels have their own connectors on the side of the power bank. For the larger panels you plug them into the input usb-c or micro-usb on the bottom of the power bank. I suspect most banks will allow simultaneous charging from the 2 input sources.
People seem to forget that it's not only phones that can be charged off of these things in a bug out scenario you can charge weapon lights or regular flashlights radios all sorts of other equipment I even have a USB chargeable lighter that is excellent for starting fires. It's basically just a coil with induction heating but it's a renewable resource that I can continue charging up off of one of these things and not rely on lighter fluid or bow drills or anything else. You can't expect wall power off of a couple tiny solar panels so I think a lot of negative reviews come from people who aren't realistic in their expectations. If you have a lot of your equipment that runs off the same 18650 batteries or other rechargable batteries and you have a USB charger, you can continue using that equipment long after the power grid goes down and generators run out of fuel. Most of the stuff that plugs into your wall is just a box with a step down transformer that usually bumps it down to 12 or less or 5 or less volts and basically anything that is going to be running in the 5 or less volts can be USB chargeable.
Nate: I think you hit the nail on the head about expectations, and if the grid ever did go down it's a heck of a lot better to have something like this than nothing at all. And while the technology is far from perfect it's not really that expensive. I am definitely willing to pay a couple of extra dollars for the added functionality. Thanks for your thoughts and thanks for watching!
Thank you Randy for a rare, totally unbiased evaluation. Well done.
Thank YOU for watching!
I've owned at least half a dozen power banks and I was always interested in the solar. I bought one that had 5 total panels and here's my $.02. They will NOT charge under indoor lighting so don't try. Also don't try and charge them indoors next to a window like this guy did. They need full direct sunlight and a lot of it. They are a doomsday device only and not intended for everyday use. I bought one for my daughter's bug out bag.Great for camping and such but not for the power hogs.
Wing: I agree with most of your points. Outdoor charging is definitely the way to go if you are trying to make use of the solar panels, but don't forget if you are a power hog you can always just charge it with a cord. Thank you for sharing your thoughts and thanks for watching.
The first thing you do when you bug out is get rid of the phones 📱

i know you are pretending to be delirious but uhh... no.
Because solar panels generates electricity from UV (not necessarily sun light) when you tried to charge the power bank from indoor, behind the window, most of UV where blocked by the double glazed window... that's why it did not charge!
Correct. I have addressed this in videos I have done since this one. Most of the photons get reflected. Thanks for watching!
That's it, charge it up on your mains, top it off with sunlight when out and about.
Thank you, Rando, for this video. Really well done and I was able to understand all. It seems this type of device is just made for my aim: long-distance cycle touring when sometimes I can stay at some organized camping ground and some time at wild camping sites. So it permits to maintain the power bank at least partially recharged while traveling between two AC provided sites.
Thanks Dmitry. I'm glad you found the video useful.
I feel like your use case is really what these type of products are designed for. Take care and happy cycling!
I have the same one in your video and it works well if it's in full sun and is maximized. Something to keep in mind is that most glass has UV protection and will stop or reduce charging of any solar device.
So... trying to charge one on the dash of the car wouldn't work?
I believe I have this same model, but it is only one part of my portable / backup power solution. I almost never use its attached panels (maybe good for 5W); instead I connect it through an adapter to the same much larger solar panel (100W-200W) that charges a portable power station. This device can charge my phone, UV-5R, razor, and other USB devices, plus charge NiMH and Li-ion batteries; the portable power station can run a compressor-cooler, charge tool batteries, and run other larger lights and appliances.
Good no-nonsense video.
I have the AddAcc version, (7.5W) coupled with an Anker 21W panel that connects into it via the microUSB. As most powerbank batteries are 18W I’m pretty sure it’s not getting the full 28.5W I could potentially be capturing, but between its own 5 cells and the large Anker cells I can charge the whole thing from flat to full in about 9hrs.
I’m lucky to get a full day of direct sun as I face south and am on the south coast of the UK so have slightly less cloud than the rest of the country. Today I’ve just used the Anker panel on its own to charge a separate 21500mA power bank from 0 to 75% in 5.5hrs.
With the power I collect in the AddAcc solar bank and the separate Ravpower bank I charge my phone, iPad Pro, Apple Watch and air pods overnight where necessary and have essentially removed all of the devices I use all day for work from the ‘grid’. They’re all super-low power devices I know, but it’s a start. Any power left in the AddAcc gets used to top up the Ravpower bank and then it goes back outside first thing in the morning.
I carry the Anker panel with me too so I can charge power banks in the car (laid across the dashboard), at work (works well in a window, unlike the AddAcc unit, we also have a roof terrace I can use) or even on the beach.
If Anker can produce a battery unit that fits in their large 21.5W panel and has a digital readout displaying charge percentage and power input/output then I’d be absolutely all-in.
Ben: Wow. I admire your commitment to this. I have flirted with getting some panels. I think if I'm going to get serious about solar that will be my next step.
Thank you for sharing and for watching!
Hi, did you do the recommended first charge for 5-6 hours using regular electricity? That's what some of them say to do. It might have affected your results. Thanks for the video. It's always good to know how different settings affect a product.

FYI, it's STILL not a phone.
Never put these in direct sunlight over 85 degrees. I've had 4 of these with different options. I made the mistake with my first one. The unit swelled and was on the verge of exploding. I believe many of the manufacturers recommend indirect light for charging.
Allen: Wow. That's crazy. I have charged my power Banks in heat well over 85° many times and I have never had something like that happen. I guess I'm lucky. Thank you so much for sharing your experience with us and thanks for watching!
@@RandoTechInfo yeah I've replace three batteries now in my power banks. Then my cell phone battery just recently swelled from direct sun. Split the phone in half. I had to rebuild it. You have definitely been lucky. Hope that luck keeps up for you.
Though aren't they ineffective when exposed to indoor sunlight?
@@rimabdallah7050 You are correct. You get basically no charge indoors.
@@rimabdallah7050 they can work on indirect light through windows on hot days. They don't charge as fast but less likely to swell from extreme heat.
I picked up a single panel solar power bank. My purpose is a little different. People in our group each picked up a single panel one so we can go an entire day without having to use another power bank. The solar keeps the power bank topped up with trickle charge solar the entire day. It lasted me and my friend the entire day. We were doing pokemon go the entire day in the summer for an in game event
Wolf: Good idea. Glad it worked out! Thanks for watching.
it took me 1 year to charge cos i live in england
😂
YES!!! You Sir, won a subscriber. I was searching for a detailed video and this is the best I have found. After a strong snowstorm and NO power for several days, I really appreciate this very well explained video. Thank you.
MiMi: Thank YOU for watching and for the sub! Glad you found it useful. Stay safe out there.
I can’t seem to figure out why anyone would look to a pocket sized solar bank to help them during a friggin snowstorm where there is no sun.
I have the single panel version an got to say it let me down big time, I spent 8 nights out in a heat wave. Took it out fully charged it worked for 1 an a half days. An that was it it was literally in direct 20 odd degrees of beaming sunshine an maybe got 2% out of it. It doesn't look broke or there are no lights to signal that its broke.
No banks that I currently know of can charge fast enough to keep up with steady use. For that you would need larger panels.
The technology is certainly still far from perfect. Hopefully in the next few years solar panel efficiency will improve. Time will tell.
Thanks for sharing.
There is also the excellent SUNSLICE, here the review: ua-cam.com/video/OhDhfTRBPmI/v-deo.html
No you have to have a proper external solar panel with more wattage then Total wattage capacity of the battery inorder to charge said battery efficiently. Solar power is important but dose not and can not replace the grid. You are better off to wait for hydrogen generators which will be very expensive but more realistic then replacement for fossil fuels.
It's best to have the panels at an angle to face the sun rather than having it lay flat on a windowsill or table, this enables the panels to collect more sun.
Exactly.
I've used one of those for the last two years of full time boondocking. It's come in handy as a backup to my solar system but it doesn't really charge up all that fast, maybe one full phone's worth when angled toward the sun on the longest day of the year in the desert. Recently the battery started to fail such that it would take forever to charge and then it would discharge far to quickly. Over all they're gimmicks and not meant for regular use.
Not Friend Eater: I think it's a little bit harsh to call it a gimmick but I agree you would not want to use the solar panels for consistent, fast charging. I also agree it would probably work best in the desert. Perhaps I will take a drive and do another review. 😆
Thanks for watching!
Those solar charger system do not have a long life. Not for regular use. Emergency or a trip..
Thanks for the info. So probably best to go with a stand alone solar charger with a stand alone power bank for long term consistent use
I'm sorry, I'm really confused. You laid it out each midday giving you three hours of light in the summer + guessed 8 days would make it an accumulated 24 hours total to charge? :S also I didn't see if you tests whether the quoted mah was correct? I tried watching it a few times :s thanks for sharing
I have a regular Power bank which works very well with any phone. However, i would'nt recommend a solar power bank as this device could take your phone a couple of days to charge while a Regular power bank only takes a day to fully Charge your device. Just a thought.
Wagema: I would agree except you can use a solar power bank the same way as a traditional power bank. It will change with a cord. The solar panels just give it some versatility (at the cost of a little extra bulk.)
Thanks for watching!
This solar powerbank is like the Poweradd power bank with 4 panels. It weighs a pound. I left it by the window in direct sunlight here in California, so you can imagine how much sun that is. I planned to leave it for a week to see if it will fully charge since the instructions says 50 hrs of sunlight to fully charge it. Before this, I charged this a few times using a wall charger and used it. It worked as it should. It still had 2 bars in it when I tried to solar charging. The indicator showed it charging when the sunlight hit the panels. Then I totally forgot about it. Over 3 weeks later, I remembered to check it and the charge went up to 3 bars. 3 weeks to up the charge to 3 bars from 2. Blah.
I'm actually surprised you got that much charge out of it. I have never been able to get any charge when trying to charge inside through a window. Thanks for sharing.
@@RandoTechInfo Thanks for making that comment re charging through a window. I have an older solar charger (POWER NEWS 300000 mAh capacity that I purchased several years ago and then never used really. I have had it sitting in my window for a couple of years and every now and then I see if it will charge my phone - it never does. I thought I had a bad unit, but your comments make me think like it may work but really needs to be in the direct sun (for solar charging). Thank you.
@@markmayotte301 Happy to help.
The idea is good to have a power bank that charges with solar light, but so far none of these compact ones does charge in a reasonable time
They aren't very fast, that's for sure,but it can be better than nothing. Thanks for watching.
Hi Randy. I purchased this exact device last week. It is June and we have had some very sunny days. I left the solar charger opened in the direct sunlight for three days. The charger started at two lights and by the end of the three days, it was still at two lights. The device appears to work in every other way apart from charging up in the sun. The device was flashing indicating it was charging. Do you think it is faulty or was 20 hours of direct sun not enough to raise the indicator by one light? I suppose it could have gone from 50% up to 74% and the light not change up to three lights. If these devices had a better way of showing how charged up they were then you would know how much charge is accumulated in the time that you left it rather than thinking the thing is broken. Any feedback would be welcome.
Charles: I totally agree with you about the light situation. The lack of a numeric readout is an issue.
On my unit the lights flash sequentially while it is solar charging. Is yours doing the same thing? If it's not, I would say you have a defective unit, if the lights are flashing sequentially then maybe give it another day or two.
That's my advice for what it's worth. Please update me on your situation if you figure anything out. Thanks.
Hi Charles do u have an update on your unit?

I recently made another video with 65 watt solar panels and I was pretty impressed with their output. Thanks for watching!
goód enough
i was planning on getting something like this because im going to camping in the woods for 2 weeks straight (army/military service) but then again its most likely gonna be cloudy all the time, its cold like -10 to -20 celcius and in the woods probably wont really charge the powerbank at all. So i think it just means no phone after my other powerbanks go empty with ultra power saving mode maybe in a week.
Mr Tordse: Those temps are gonna kill any and all batteries and power banks. In the scenario you will be in, I'm not sure how helpful the solar functionality will be. If you are out there for two weeks you might get a LITTLE extra juice from the solar but I certainly would not count on it.
Thank you for your service and good luck out there.
Damn just tell me if it work! Just kidding, thank you sir
x2: Thank you for watching!
Seems like one would only fully charge this once. If hoping to use when power is out it's extra panels are really of no use after the first time because it would be being used daily not once every 8 days to let it charge to full again.
tahaji: What you are saying is not wrong, but I also think the scenario you present is not the product's intended use. You would not want to use this as an only source of power for an extended period of time. (You are correct that would clearly not work.) It is simply a way to get some additional/free power when away from home or an outlet for a few days.
To use your example, if you lost power, and were able to get some solar charge, you might get an extra couple of days out of it, as opposed to a battery that had no panels.
Solar energy is not in place yet to replace a lot of major power needs, but I do think the supplemental power it provides can be useful in the right circumstances.
Thanks for taking the time to share your thoughts and thanks for watching.
Not only will a NON-USBC connection take longer to charge, it will fail in 9 months to a year with normal use!! I'm living proof with 2 Doss bluetooth speakers which are effectively Earth-polluting bricks, smh.
mAh in batteries are not equivalent ratings. You have to convert to Wh first to make them a direct comparison. On top that you won’t achieve 100% efficiency of transfer. 4000mAh in battery will not fully charge a 4000mAh device even if same voltage. You will lose power to heat and electrical resistance. I’d like you to charge your phone fully and watch that battery go down 30-40% and make a new video explaining that portable charger would take multiple days to generate the energy to charge a phone. You would need several of them to make regular use of the device if only using solar power.
Remember with solar panels, area doesn't lie. Allow 3 W max per 12x12 cm square or per sunpower cell.
USB 2.1 Amp is slow and outdated. It will not be good enough to charge my note 20 ultra. My phone requires 3.1 Amp to charge it. I opted for the 40000 mili Amp power bank
What i have found is, the solar in my Power bank is for emergency charging. It will give enough charge for the flashlight to work for a bit. My bigger one, might get my phone charged enough for a call?
.
My hand cracked solar charger only works the radio and flashlight. You have to precharge the (10k mah battery) to charge a phone.

Absolutely. Anything you gain with portability you will also lose with charging speeds. Thanks for sharing!
@@RandoTechInfo There you go.
I bought the 43800mAh solar power bank and it only charges to around 4000mAh. Just get a well recognized brand power bank and not those chinese solar ones from Amazon.
When the hurricane is over & you have no electricity, for days- Im thinking something (if charged) is much better than having- nothing, so if you have an emergency call to make, they seem fine.
I honestly think the test should happen a different way like the solar panels are meant to charge the phone tablet etc during the day and battery operated during downtime from the sun like cloud coverage maybe for a few seconds then at night when you have no sun I think why it charges the actual device slowly is because two things one if you’re not using the solar panels to charge a device then the power goes into the batteries two you have lithium ion batteries in direct sunlight and when batteries is being charged it warms up also the sun’s rays heat up the batteries honestly I just think it’s a design thing as a safety feature for the device and to conserve battery life for when you don’t have sunlight just my thoughts
I think it’s good to have as a back up. May take days to charge but 4 days is not bad as if your only using to say charge your cell phone it will do the job. Good just to have you never know get it why it’s cheap before china stops trades lol 😂
It’s crazy that these things take weeks and sometimes months just to get a bar of charge from these things. Sometimes they don’t charge at all. I don’t even know why they call it solar power chargers Lol. My outside Solar lamps charge faster than these things. And they have to nerve to charge $20-$100s for them
I'm actually putting the finishing touches on a video where I test 28 watt solar panels. (The solar panels on the power bank from this video total 6 watts.)
I think you might find it to be a better solution.
Thank you for watching!
I don't know if power banks operate at 100% efficiently
I think its closer to 90%
Keeping them in a window is a good way to ruin the device completely. It will never take a charge and only stress the batteries out and eventually they will start to expand and not hold charge at all
I will be getting a few of these. I am also interested in a Bluetti battery bank but they are very expensive.. i will also doing reviews on the solar chargers
Knives: Good luck with your reviews. My power bank reviews haven't had a lot of traction, just the videos about how they work. 🤷 Thanks for watching!
I just got my "winlove" branded solar power bank. It looks identical to yours, except the red trim bits. I'm looking forward to playing with it.
If a person is relying on the solar to keep their devices running, a minimum use strategy on the devices will help extend battery life and these small solar panels may be more viable. Just a thought.
Agreed.
they fully charge with 48 hrs FULL sun exposure....meaning not just 2 days
"Do Solar Power Banks Really Work?" Mine doesn't! My Li-polymer 18000mAH 5v power bank should be equally chargeable from its built-in solar panel or from USB. It charges OK from USB, but sunshine causes it to discharge instead of charge. Blue LEDs correctly indicate presence of sunshine on its solar panel, but this sunshine causes battery to go down instead of up. I can only suspect internal wiring between solar and battery must have reversed polarity somewhere. I seek guidance on how to correct this
Wrong solar never solsrcdusached
I think it's good enough for an emergency phone call or for camping .like how it can be carried discreetly like a phone
Thanks for taking the time to perform the test and sharing it. I guess the answer is no. If it takes days to charge a bank, that's terrible and completely not practical for any sort of usage. It seems like it would make more sense to charge the phone or devices directly through a solar panel vs taking 6 days to charge a bank and then another hour to charge the phone/device.
I tested that as well if you're interested.
ua-cam.com/video/DNNIdc8C19o/v-deo.html
I can’t find one that actually uses sun . The solar panels are fake on the one I bought abd every other one I research . Is there a single one on the market that actually uses the sun to recharge or is it all just bullshxt? Edit: So this one does, just slowly?
Juan: I have never run into and "fake" solar chargers. Where are you buying from so I make sure I don't shop there.
In any case yes, the panels on the bank in the video do indeed work.
Thanks for watching!
Seems like all the 4 panel charges take a week in optimal conditions with full day charging. Single panel chargers take a minimum of 2 weeks. You would be done with your camping trip, hike, or rescued by time these things charge. smh Great video, ty, but I think I'll pass on these devices. I wanted one for the SHTF scenario. If SHTF you're probably always on the go, so this may not be a good purchase. Originally I was thinking just velcro it to a backpack with the panel facing upward and let it charge. I don't think it's gonna work. Then again my Bday is coming up, so maybe I should post on FB a link and Bday coming soon msg, and hopefully get lucky. lol
It's funny, we used to have to figure out ways to drop hints to people to get what we wanted for our birthdays now we can just post them online. 😁

I wish I had seen this before I bought one from "my Patriot Supply". Not only did it cost WAY MORE but its detective and they won't pay my return postage. Please stay honest so people like me will still trust. By the way, it recently got marked down to half. Wonder why?
Cheryl: Not familiar with "my Patriot Supply" so I'm glad to get some info. The charger is no longer sold on Amazon either. The one from the video still works but I have a LOT of power banks so no particular one gets too much use anymore.
Thank you for taking the time to share with us and thanks for watching.
8 days to charge 75% ? Man thats kinda slow
6 days to charge 75%. 8 days to charge fully.
It's definitely not going to break any speed records but remember this is a huge battery. A smaller battery would obviously charge to capacity much faster. You can also just charge via the wall when available.
Thanks for your thoughts and thanks for watching!
@@RandoTechInfo I see, thank you for your reviews!
8 days 100percent 12 ays bad weather
if you consider that in greece we have your kind of sunshine at least 50 times more it would be logical to assume the powerbank would charge in a days time !?
I don't think so. Even with MAX sun, I'm guessing it would take multiple days to charge.
If you do pick one up though, come back and let us know how long it takes to fill up. I'm curious.
I ordered one today off ebay, $20 with free shipping from the U.S.
Frank: Come back and let us know what you think.
@@RandoTechInfo well I tested the mah capacity with a usb tester and it said 17,003 mah, although it will likely go up over the next few charge cycles. Not sure exactly what to expect there but I'll let you know if you'd like.
@@franksmith7271 That would be great. Thank you!
. 2nd charge brought it up to 17,604mah charging it again now.
@@franksmith7271 Good to know. Thanks for coming back with the info.
Lol, I bought this just to keep from using power adapters, and saving energy. With a fully charged 25,000 mAH battery, I'll be able to charge my iPhone XS up 9 times, which literally means 8-12 days of use without a power outlet! Not bad, and it would definitely come in handy if a bad storm or tornado came threw and knocked out the power for a couple of days (like it did last year during Easter). Worst case scenario, if I forgot to charge the power bank up, I can just open the panels up and put it on my car's roof and charge my phone that way.
Joshua: They can be very useful, especially in a pinch. Thanks for taking the time to share your thoughts and thanks for watching!
You're welcome!
Bro I have a question does it affect battery health?? I’m also an apple user iPhone X. Was it???
Thanks for the useful info.
Has anyone ever told you that you look a little like the comedian Jim Breuer? You've got those slightly "stoner eyes" too, lol. That's a good thing, btw. ;-)
Rob: Goat Boy Tech Info 😂
Forget that! Buy a regular powerbank and get a 10-20 watt solar panel that is usb compatible.
I just charged my nitecore 14000mah power bank in about 2 days.
...but then again I'm in Texas lol.
Hey john. I'm actually going to be putting out a video here soon where I test some 28W panels. Hopefully we get some promising results. Thanks for sharing your thoughts.

Can someone help me out. I have a feob solar charger with 3 external panels. When I put this device in the sun. When I don’t have the external panels attached it indicates it’s charging but when I connect the external panels the light turns off and it won’t indicate it’s charging. How do i fix this?
Josh: Unfortunately I am not going to be of use to you on this. Hopefully somebody helpful will see this and get back to you. Thanks for watching.
Well the instructions do say not to depend on the solar system for "phone ;) " charging but that it's there in case of in a emergency when you have no way to charge your device. So one would not or should not have to wait many days for a full charge but to get just enough power to be make a short call vs not being able to make any calls at all with a dead phone.
Forgot to mention in black outs the led lights last a hell of a long time also the usb can power a 12v usb fan when the AirCon or outlet fans have no power to cool you off. You would be good with light and a breeze to spare :) People may be like oh I'll just use the led light on my phone, but it's dead with all the social media stuff and calls one did all day long. So in a situation like that we pull out the "brick"
Puchi: All good points. I see it the solar charging capabilities as a back up or an additional way to charge, not something to use on the daily.
Thanks for sharing your thoughts and thanks for watching!
The discription sais that it will not be charged behind a window. ( in my discription )
kru: Good. I'm glad they are being honest. Thanks for watching!
THERE ARE NOOOOooooo MORE!!??OF those power banks left on AMAZON in the video😭
Martin: Crap, really? I did make it a while back. Hopefully they will restock. Thanks for sharing.
I wonder how many phone charged it would take to recoup the initial cost of the device itself. I like the idea of solar to save money but not sure if this would save me money. Hmmm
I do not feel like it is necessarily a money saver. The solar charging just isn't quite fast enough for that. I just feel like the solar panels add some nice utility for not a lot of EXTRA money, if that makes sense.
I don’t know nothing about nothing but six days to charge it is ridiculous.
2-3 Days with a usb-c cable, assuming constantly plugged in the is 48-72 hours, that is a crap charging rate
Wrong it's fast solar Haring we Ned ore Sar El some 6 panel 9 panels 9 solar panel charg f as yer
Buy 2 of them... keep one charging and use the other one and just rotate so one is always fully charged
Genius
I bought one of these but it will not charge by the solar panels. I discharged it by charging my tablet 3 times and my phone twice. Then I put it out in the sun for 7 hours 3 days in a row, and there was only 1 blue LED lit. Piece of crap.
Dwight: I'm sorry you haven't had better luck with it. Are you using the exact model from the video?
@@RandoTechInfo -- It's the same item. It charges great from an AC to DC adapter, but not from the solar panels. The 3 removable panels attach via a magnet and are eletrically connected to the battery pack via 2 pin connectors. I wrote it off to the fact that the Chinese having no Quality Control. I may take some of my federal stimulus money and buy another unit. I waited too long to return it. I really want a solar--charged battery pack in case I lose electricity to my house for an extended period of time.
Wring mot crap need faster dlaroiwrr sink chargers
I believe that glass blocks some light, so it would reduce the effectiveness of the solar panels
Phillip: Big time!
Cool video. In your opinion what is the best top 5 solar banks on the market? Is there a practical option between 200 to 700 dollars or will I be getting junk? I'm new to this type of device but looking for a good device for emergencies? Thanks buddy.
Pops: Not sure about a top 5, I can give you a top 2 though.
I do really like the power bank I used for this video. It still works like new and the fact that the "extra" three panels are detachable is a really nice feature. (And something I didn't mention in the video.)
Here is the Amazon link: www.amazon.com/gp/product/B07V2CQVV3/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
A less expensive, but still really good choice, is the Tranmix Solar Power Bank. It's missing a USB-C charge port and the extra panels are not removable but for under $30 it's a nice value option. I did a full review of this one if you want to check it out.
Here is the Amazon link:

Hope that helps. Thanks for watching!

Your maths is wrong with the lights i think.
4 lights is not 100% it is i above about 80% that is why the fourth light doesn't turn off the moment you plug a device in to charge and the battery bank drops to 99%.
So 6 days in full sun probably charged it to somewhere closer to 80%
Dude: Hmmm. I will consider your words. Thanks for watching.

All of the Amazon reviews of these type of products say they carry extra power, but get no power from the sun.
Apple: I don't think it's fair to say they get "no power" but it's not the fastest way to charge to be sure.
Hey I’m in the market for one of these solar power banks but I’m sketched by all the fake ones on Amazon, do you recommend any with a legitimate high capacity mIlliamp hour rating?
Power bank I used in the video is no longer available and I'm not really sure what's all available out there right now. I know a lot of people like Blavor. Perhaps start there.
yes chef know real capty fr8mmanazon nit fake one ship wiht chief
In short, I believe they do work. No they dont charge your phone as fast as a regular charger but they have good battery and a led light. Plus some of them are even waterproof and drop proof. I have a 4patriots one and I love it.
kendal: Thanks for sharing and for watching!
You're actually better off getting a single cell power bank and a separate 30 watt 12x8 solar panel charger. On a sunny day you can charge this in a few hours.
I did a whole other video about that. I don't disagree.
It's the setup I use and it rocks for glamping. Keeps my battery bank and portable devices topped off easily.
Yikes this video was a mess. But hey least you showed everything including the flaws in the video. Like not knowing the product by not knowing how to turn the light on. Then testing it indoors from a window. We all make mistakes and learn from them
My testing since then has become a bit more polished. 👍
@RandoTechInfo haha same when I started. Now I'm a addict to all the solar stuff
Note to self need sun to charge! 😂
yes the do very slow char rat 1 or nuot ohibe charge prr day
I charge my phone using solar panel only during the day and night time use power bank to charge my phone. I’m Saving battery life on power bank.

The heat from direct sunlight would destroy and degrade the battery significantly. Solar powerbanks are extremely slow because of the small surface area of the panels and is inefficient.
A solar charger through glass works at only 9% of its capacity.
Depends on the glass. That's probably close though.
If i get 30 % a day in winter for phone ill be amazed and my no escape dog harness omg
Depends where you live.
Can it power up using inside lights in house ?
Also what’s the cable for ?
No. Indoor lighting will not charge it. The cable is for attaching the bank to whatever device you want to charge. Let me know if you have any other questions.
You got a good one, my don’t charge in the sun I got rid of my Amazon £48,00 UK 👍🇬🇧👋🙏🇺🇸
Psv: Yeah, I have heard this from others. Sorry you got a dud. Thank you for letting us know!
