Video is very good. I bought a renhotecic power supply not long ago and tested it, and it feels that the effect is OK. It is recommended that friends in need can try to prepare a copy.
50800mAh at about 12V (which is a safe assumption for a voltage rating of a car starter) would be about 610 watt-hours. The highest capacity 18650 on the market has a capacity of about 13 watt-hours, so you'd need 46 of those high capacity (read: expensive) cells to make one of these. That would make for a very large and expensive device (ie. not this one).
i know this is an old video but just to warn you about keeping this unit inside your car. In the summer time when the temps are high the li-ion batteries don't like heat and so just be careful where you put it inside of the car and make sure the temps don't exceed 150F which is very easy in the summer time inside a vehicle
I don't think I heard ya mention, but if ya look towards the top, there is a knife looking area? That's to cut a seat belt, if someone were to get caught in an accident and couldn't reach the unbuckle button. And the Metal shiny diamond at the bottom of the unit is to bust a window open if a car was hit in the door and the door won't open in an emergency. I will say, like the other commenters , that 50k sounds a liiiittle high for the size and weight, but from what you have gathered, it's a pretty high capacity regardless! Thanks for the Review man! Good stuff!
To all the trolls on here commenting about no battery test. IT COMES WITH A STICKER THAT SAYS IT IS CERTIFIED! AND IT IS MADE IN TAIWAN SO IT IS QUALITY!
Elektronik 400g you haveing a laugh don't worry about Grams it's no way to get 50.000 mah in some think that big but it this way most car battery's are about 26.000 to 40.000 so in less this in from the future there no way
Nice! I think you might have forgotten to mention another difference the two units had... the yellow one had a metal protrusion at the opposite end from the lights. That is a safety feature to let you get through your windshield by breaking the glass. It also explains the choice of material in the black part. It is probably rubbery and provides a good grip when hitting the glass.
IF YOU OPEN UP THE RED CABLE BLADE, YOU WILL FIND 10 POWER TRANSISTORS IN THERE WHICH GIVE THE PEAK BURST OF POWER. I don't have this exact unit and bought mine in 2014, when they came on to the market.But it does start a 3.9L car in good condition. The charge socket however, keeps falling off as the plug is very thin, and it levers off the socket. I have sent it back twice now and it has happened again. It's a useful device, I am going to make my own charge cable with a bigger prong as this is its real weakness, when they send me another
I want to see you completely run down the battery on this to see if it really 50,000 mah please I want one but it just seems unreal thanks love the videos and keep up the good work hope you get better soon
Had one of these it was good for around 8 jump starts (worked well) now says it's 100% but wouldn't start a fight just now it's just a big fat torch, save your money.
the tm15 model has only 6000 mah. I confirmed this with the manufacturers. I tested the device from fully charged to zero to charge my fone (4000mah battery) and found that it can only charge the fone a max of one time
Easy and accurate way to test actual battery capacity against claimed capacity is to fully discharge the unit then use the 1000mAh wall charger to fully recharge it. If it actually is 50,800mAh it will take more than 50 hours to fully charge it. I would bet that it charges it overnight.
I did this test on a unit owned by a friend as I simply didn't believe the claimed capacity. The wall charger was rated at 15 volts putting out 1 amp, it only took about 5 hours to charge. That's about 75 watt hours of charge to fully recharge the battery. Based on charging time alone, that would make it the equivalent of a 5.8 amp hour battery at 12.8 volts or 20.2 amp hours at 3.7 volts. The labeling of 58800 mAh is quite obviously misleading otherwise it would take MUCH longer to charge. One thought I had is that it's 58800 mAh at only 1 volt. These units should quote the rating AND voltage or use watt hours. Having said that, this unit is cheap so might be OK if it could restart your car and charge your phones in an emergency. I was able to fully charge several phones and a camping lantern before flattening the battery.
Also note that the documentation with the unit was almost useless - it had no details about charging time etc. There weren't even any details of the internal battery used and what the capacity actually was. It was very cheap so I guess you get what you pay for.
The usual misrepresentation in capacity of mAH ratings in Chinese battery packs is to add the sum of individual cell ratings, even in a series-parallel circuit (eg, 11.1 VDC from 3 series sets, of 2 parallel sets, where real AH capacity is then 2x cell ratings, not 6x). Beyond that, there's a Chinese culture of fraud to flat out lie, that's also found in laptop packs, flashlight cells, etc. 50800 mAH from 6 cells would require 8500 mAH cells, using that 6x distortion, whereas high output 18650's tend to run 2000-2500 mAH (and most regular capacity cells unsafe for loads over 3 amps no more than 4000 mAH, with many labels higher than that frauds). That means a pack like this if it uses high output rated cells is more like 11.1 VDC 4500 mAH real capacity, and if those are 25 amp rated cells, 50 amps safe output current. That's why there are other reviews of similar packs, some that lie worse than this one with 1000 amp claims, that show fires, explosions, wiring meltdowns, etc.
I bought one of these on Amazon and kept it in the trunk of my car. Twice a year I would take it in the house and charge it. Last Thursday I was charging it in my home office and it blew up and caused a fire. Luckily we were home, and I had smoke detectors in the basement where my office is. When I went downstairs there was a fire 3 feet wide and 3 feet high. We had a fire extinguisher and I was able to put it out, but it caused lots of damage and the whole house smells like smoke now. It clogged my air conditioner and completely blocked the filter so it froze up and I had to call a service man. I wonder if anyone else had one of these blow up on them?
Can you overcharge or over discharge the lithium batteries or is there adequate protection on both ends? Can it stay connected to a battery to assist it charging if your car battery is weak?
yeh but still just a handy to have in specially in middle off forest in winter no lights and power here you have nice ski trip tent lite and entertenment laptop power source
It would be nice to test the MAH of this battery. I suspect it is overrated like most of these power banks. The MAH is usually rated at the batteries voltage not at the boosted output, so a 5,000 MAH battery at say 3.7 volts is more like 2,500 at 5 volts and so on. I load test all my power banks and all of them have the rating based on the battery. Something to keep in mind when purchasing one of these. If it can actually jump start a car I would say it has good power.
12.6V rating on the wall adaptor!? Does it have the entire lithium ion charging circuit in it? 12.6V is the nominal cutoff voltage after the charging current falls to 1/10C.
You can not go by weight. I bought a used battery pack at a yard sell for $2. They told me it would not hold a change long but I wanted it for parts so it did not matter. Any way when I took it apart I found several metal plates inside that did nothing but add weight. Well I got my $2 out of it.
I have one claiming to be 68800 mAh. I tested it with IPad Air 2. Drained its battery to zero, turned off, connected to power bank and let it get charged. After a bit more then 2 hours it did charge IPad draining itself down to 30%. Remaining power disappears in matter of 15 minutes when charging anything else is attempted. The numbers seem to be grossly exaggerated. IPad Air 2 has battery rated at 7430 mAh. Judging by the numbers one could expect that power bank should be able to charge IPad almost 9 times. Seller informed me that rated power is "virtual" not real and that virtual power is industry standard. Problem is I paid with real money, not virtual. I am unable to find references to claimed virtual power. Can I get some explanations? Seems like a lot of bulldust to me.
There are so many ac power banks out there from generic to big brand power banks, that I don't know which one to buy. Because most of them lie when it comes to the mah
Warning: DO NOT give this to a car guy or anyone that have decent knowledge about car. It will be consider as an insult! This thing is like a toy tool set that you gave to your children so they can pretend fixing stuff.
Its basically works like the other jump starters battery units out there rated at 300 to 600 amps. When those units themselves have a 12v 9ah to 12v 12ah battery. So it can only provide that 50,800 (50 amps) for a very short period. Like 5 to 15 seconds or less to help start a vehicle. So as long as it is a small vehicle. The 50,800 was not suppose to mean an actual capacity. It was only meant to be used as a deliver charge for the small time frame of 5 to 15 or less seconds it takes to crank and start a small vehicle.
It not that it has a capacity of 50,800mah which is a misnomer, should just say 50 amp booster. It can only help provide 50 amps to your 12v system to help start the engine. (1000 mah is 1 amp). It basically uses the same technology used in UPS and inverters systems of taking a lower power battery. For instance inside UPS is a 12v 9ah battery. The UPS can take that battery and provide 120v for about 5 to 10 minutes depending on the load. It can also have two of these batteries running in series and have more run time on the ups. And if you used an actually car battery in an UPS you might be able to get 48 hours run time if you are just using it to power a lower power lamp So in other words it is a boost converter. Using the max wattage the battery pack can provide and shoving it all in 30 seconds for starting power. Yet who the hell thinks it was a bright idea to use LiPo battery as the battery pack to do this. Those packs are not meant to be drained that fast.Yes the other comments about its actually battery capacity are right, it is much less than 50,800.
I work in a cumputer store, there is no power bank with a 50,000 mAh lie! 22,800mAh is the maximum that is in a power bank Amazon and Aliexpress Loser Sellers
You should have done a discharge test and a CCA test. 50 Ah capacity is not possible for something that small and a 100 ah lithium ion batt retails for $1000
I really like your product selection and everything about your channel! you are quite different you choose awesome products! and plus they are useful and affordable and accurate! keep up the good work! soon this channel will have many more subscribers more than u can imagine!😊
It's Chinese, of course it's not the rating it has been given. However, it's cheap and does what it is supposed to. You can start a car with a flat battery several times and power or charge loads of other things. For the size and money, you may as well have one. I have exactly this one but badged by Floureon and I've had it about a year and it works perfectly. The bullshit numbers mean nothing.
+tyray billick no. If something is dead, it can't be made to live again. A flat battery can be recharged, a dead battery can't. There is no point jump starting a car with a dead battery as it won't continue to run. They are called "flat" because the DC line on an oscilloscope is flat on 0v line.
Everything is made in China so the comment doesn’t make sense. When things were made in America 100 yrs ago and shit broke and the tech was about as advanced as a Rubik’s cube no most people didn’t say it’s American of course.
on these it uses a 4s 14.4 volt high drain lithium battery flat pack, like they use on remote control monster trucks, those are usually 2 to 5 ah (2000 to 5000 mah). So I'm also confuse how its got its 50000 mah (50 ah) rating. These will not power a laptop for very long maybe 2 hours at the most and thats for a small netbook. As an example a 4s powerpack using 2 amp 18650 laptop cells would require 100 cells to equal 50 ah (50000mah), it would not fit in your pocket. But these will definitely start your car, as long as it cranks over quickly, that is its primary use. But they advertise it as something much more. When people see 50000 mah, they think they can use it to power large things which it can but only for minutes.
Do you know of any battery packs that would be able to power a laptop for a long time? Ideally 8ish hours. I'm looking around online but I dont have a good understanding of the numbers that are thrown around
Thanks for the rundown, mayiandjay. I think I'll go for the yellow model, after other research I've carried out. I need for dual use - charging equipment plus I currently have a dicky car battery!
Case 1, Lithium poymer battery: each 1000mah weigh about 16g, then this 50800mah power charger should has a battery about 812g, not including the shells and other parts. Case 2, it use li-ion 18650 battery cells: Each cell about 45g, let's say each cell with capacity 3000mah, then 50800mah should at least 17 cells, that is 45*17=765g, not including the other parts. Don't ask me why I know, I am battery expert.
12.6v 1amp charger will not be fast at all I guessing there are 8x18650 batteries in there 4x2 in parallel each will be capable of at least 2amps each so 8000ma charge rate would be preferred over this led security light psu.

Send this to BigClive and ask how much capacity it has
how to contact BigClive?
I think GreatScoot would do it better.
Casey Urquhart yes big Clive would Anser this non sens
Casey Urquhart I vote for Clive too
I'd love to hear bigclive review this

......and the yellow one has a wire cutter neatly safely tucked there if you all noticed . awesome !
Already used this one..although capacity is not true but it can jump start my car and recently just help someone to start his car...
I want to see you completely run down the battery on this to see if it really 50,000 mah please I want one but it just seems unreal thanks love the videos and keep up the good work hope you get better soon
I think it have 5800Mah only. It's overclaim product but it's does the job jumping my car 5 times in 1 day, still have power on it, no bar dropped.
Congrats to 100K, Jay. Keep it up. ;)
You forgot to mention the seatbelt cutter and window breaker on the yellow 1, i have one like it.
I gotta bring an updated one
Your channel is Good 😎😎😎.I love that cop light
Has an unsigned, undated, unidentified quality certification sticker. Sounds legit.
If you can only charge it at 1 Amp, it is gonna take two and a half days or so to charge it!

lol Really really REALLY NEAT.....don't take much to impress you does it....So cool....are you reviewing it or selling it?
Let's go dancing. Hey, bring with your disco lights. Lol
nice might pick this when i get my first car next month
I need something like this but with a 220v plug. Power bank for literally everything.
Check out the Omnicharge Pro. I ordered one it has a wall socket.
I have one but rather expensive, with 220V plug too. maximum out put is 500W.
Note: You cannot bring this powerbank thru airport due to huge battery capacity.
This model I bought just exploded in this November after few usages

How much
Nice power bank sir
That yelloow one looks like it has a seatbelt cutter as well as a window breaker on it.
It would help if you just mention the company and model. Or something along those lines to type in and locate it.
Can you overcharge or over discharge the lithium batteries or is there adequate protection on both ends? Can it stay connected to a battery to assist it charging if your car battery is weak?
you forgot the seat belt cutter one the corner whit the black and yellow one great back up battery
TheSuperHybrid80 great without counting the fact of the fake capacity
yeh but still just a handy to have in specially in middle off forest in winter no lights and power here you have nice ski trip tent lite and entertenment laptop power source
is there a possibility to load this power bank with a solar panel? if yes, can you recommend me one? Thank you :)
with this, i can play pokemon go forever
Like you said Jay, Amazing and I'm very impressed to see that it has 50800mAh!!! Awesome video again :)

12.6V rating on the wall adaptor!? Does it have the entire lithium ion charging circuit in it? 12.6V is the nominal cutoff voltage after the charging current falls to 1/10C.
It is illegal in most states to have blinking red and blue lights, Especially when it flashes like a police car lights!
Exactly, does it come with a licence to use those lights. ;-)
You can not go by weight. I bought a used battery pack at a yard sell for $2. They told me it would not hold a change long but I wanted it for parts so it did not matter. Any way when I took it apart I found several metal plates inside that did nothing but add weight. Well I got my $2 out of it.
the metal front is for carglash craching, no charge full mobile (20-30%) & laptop (5-10%)
Basically these units are rubbish with specification that defy battery physics.
I have one claiming to be 68800 mAh. I tested it with IPad Air 2. Drained its battery to zero, turned off, connected to power bank and let it get charged. After a bit more then 2 hours it did charge IPad draining itself down to 30%. Remaining power disappears in matter of 15 minutes when charging anything else is attempted.

Not even close to 50000 total scam
Where do I get it
yeah i had one and i ripped it off 😂 battery is 4800mah ...mention on the battery itself
I'd like to see a test of the battery capacity. Don't care about the flash modes of the stupid lights.
awesome lights on it
There are so many ac power banks out there from generic to big brand power banks, that I don't know which one to buy. Because most of them lie when it comes to the mah
Never once hooked it up to a meter and tested power output.
These thing wont give a voltage out on the clips unless there is a battery hooked up to them. It's a safety thing.
Warning: DO NOT give this to a car guy or anyone that have decent knowledge about car. It will be consider as an insult! This thing is like a toy tool set that you gave to your children so they can pretend fixing stuff.
But they do start cars with flat batteries.
I'm a certified auto tech.
it actually works.
a friend of mine has one .....I thought he was joking.
but to my suprise
Its basically works like the other jump starters battery units out there rated at 300 to 600 amps. When those units themselves have a 12v 9ah to 12v 12ah battery. So it can only provide that 50,800 (50 amps) for a very short period. Like 5 to 15 seconds or less to help start a vehicle. So as long as it is a small vehicle. The 50,800 was not suppose to mean an actual capacity. It was only meant to be used as a deliver charge for the small time frame of 5 to 15 or less seconds it takes to crank and start a small vehicle.
from my understanding a car starter needs at least 150 peak amps to crank over, these are rated to supply 400 peak amps.
Even for very short periods, they won't start a car with a dead battery
It not that it has a capacity of 50,800mah which is a misnomer, should just say 50 amp booster. It can only help provide 50 amps to your 12v system to help start the engine. (1000 mah is 1 amp). It basically uses the same technology used in UPS and inverters systems of taking a lower power battery. For instance inside UPS is a 12v 9ah battery. The UPS can take that battery and provide 120v for about 5 to 10 minutes depending on the load. It can also have two of these batteries running in series and have more run time on the ups. And if you used an actually car battery in an UPS you might be able to get 48 hours run time if you are just using it to power a lower power lamp
So in other words it is a boost converter. Using the max wattage the battery pack can provide and shoving it all in 30 seconds for starting power. Yet who the hell thinks it was a bright idea to use LiPo battery as the battery pack to do this. Those packs are not meant to be drained that fast.Yes the other comments about its actually battery capacity are right, it is much less than 50,800.
I work in a cumputer store, there is no power bank with a 50,000 mAh lie! 22,800mAh is the maximum that is in a power bank

I like this GADGET. .can I sell them here in Belize? .they are not much here..please send me the info.
You should have done a discharge test and a CCA test.
50 Ah capacity is not possible for something that small and a 100 ah lithium ion batt
retails for $1000
this is some next level BS haha, this guy just wants to get paid for advertising

At last,, The voice of reason and common sense.
Thank you.. I can start breathing once more!
11.1v 100 ah li ion batt costs 1000$ so 3.7v 50Ah should cost 160$
There is nothing that said "hour"!!Maybe it gives that current,but just for a little while.Could be enough to jump start your car.

+tyray billick no. If something is dead, it can't be made to live again. A flat battery can be recharged, a dead battery can't. There is no point jump starting a car with a dead battery as it won't continue to run. They are called "flat" because the DC line on an oscilloscope is flat on 0v line.
I didn't know that thanks for the info
Everything is made in China so the comment doesn’t make sense. When things were made in America 100 yrs ago and shit broke and the tech was about as advanced as a Rubik’s cube no most people didn’t say it’s American of course.
you forgot to show the most important function of this thing "HOW TO JUMPSTART" and is it work??
awesome video
on these it uses a 4s 14.4 volt high drain lithium battery flat pack, like they use on remote control monster trucks, those are usually 2 to 5 ah (2000 to 5000 mah). So I'm also confuse how its got its 50000 mah (50 ah) rating. These will not power a laptop for very long maybe 2 hours at the most and thats for a small netbook. As an example a 4s powerpack using 2 amp 18650 laptop cells would require 100 cells to equal 50 ah (50000mah), it would not fit in your pocket.
But these will definitely start your car, as long as it cranks over quickly, that is its primary use. But they advertise it as something much more. When people see 50000 mah, they think they can use it to power large things which it can but only for minutes.
jony joe ,,,
Do you know of any battery packs that would be able to power a laptop for a long time? Ideally 8ish hours. I'm looking around online but I dont have a good understanding of the numbers that are thrown around
Thanks for the rundown, mayiandjay. I think I'll go for the yellow model, after other research I've carried out. I need for dual use - charging equipment plus I currently have a dicky car battery!
can u please share the purchase link and i want to buy this product from india
Please do some clone smartphone
unboxing after this
I am working on it, you might be impressed!
+mayiandjay Blow us all away Jay ;)
No way in 2019 to achieve 50.8 amps from such a small package
is it able to charge a hoverboard? if it is able, will the hoverboard or this charger have any defects after charging it?
More like true 50,800 mA ( milliamperes) instead of the silly typo label as mAh.
Nice talking and colorful lightshow, but can this "Jump Starter" jump start a car??
what is the brand name and where did you get it if you could put a link in a comment that would be great
Hello when you used it to start your vehicle, you didn't mention what type of the vehicle the starter is able to...
Case 1,
Lithium poymer battery: each 1000mah weigh about 16g, then this 50800mah power charger should has a battery about 812g, not including the shells and other parts.
Case 2, it use li-ion 18650 battery cells: Each cell about 45g, let's say each cell with capacity 3000mah, then 50800mah should at least 17 cells, that is 45*17=765g, not including the other parts.
Don't ask me why I know, I am battery expert.
Stephan Cheng i love china. Start loving china since my first Bluboo phone. I never been there. But i would like to go someday..
And since the jump-starter is 3S you have to multiply the weight by 3.
Uh-oh mayiandjay
, this didn't go well, Huh! 50800mAh, are you sure about that?
Tesla motors will start thinking to buy this battery for their cars to run continuously for 24 hours or 100,000 kilometers, which ever comes first.
Excellent!
perfect but not for lenovo laptop I really like it
Disappointed I don't see a direct link to the purchase page of this.
this wont explode will it?
No explotion on these!
can I charge this power bank with the car
It would take 50+ hours to load when drained with that adapter if it is really 50800ma/h
I was actually looking at this the other day.
When is the HDC note 5 5.7 is going to come out ?
congrats jay for ur 100k subs +mayiandjay
Good day Sir, do you think this jump starter can start a 2.8 diesel engine vehicle? thank you.
And the question is, how much minimum mah we should buy to really jump start a dead battery car??
you forgot to mention the glass breaker and seatbelt cutter
I want to buy one now but can it change a type c laptop????
12.6v 1amp charger will not be fast at all I guessing there are 8x18650 batteries in there 4x2 in parallel each will be capable of at least 2amps each so 8000ma charge rate would be preferred over this led security light psu.
1 amp charger on a 50ah battery... if it doesn't take 50 hours to charge, it's way below capacity
I'm going on a trip to Managua, Nicaragua on June 12th for an entire week do you think it will last that long?
You didn't test the claimed capacity and start current?
Hey man! Do you have giveaway of this jump starter with 50800mAh? Thanks.
Nice !
Is this for diesels or for petrol thanks
