Today, let's take a look at a 12V 500A car jumpstarter from Lidl supermarket. It's a 12 000 mAh (at 3.2 V) USB power bank with a jump starter that can start your car when its lead acid battery is dead. It contains a Lithium Iron Phosphate (LiFePO4) 4-cell battery (3000 mAh 12.8 V). Let's unbox it and see what's inside and how does it work.

I'm glad that we have DiodeGoneWild to test those deadly devices XD

[@rfmerrill]

It probably has some logic to detect that it is connected to a lead-acid battery, and the 'factory' button temporarily bypasses that logic so that the output can be tested on a more simple load, maybe just a power resistor and a meter for factory test.

[@OfficialHummerJumpStarter]

When your car battery is not there, no LOAD, it need to bypasses the protection I think.

[@BillAnt]

They forgot to built in an idiot tester too. xD

Looks like this one is for once a quite sensible and useful powerbank. :) Nice buy! Thank you!

[@antibrevity]

I was expecting this unit to be much worse, but it's surprisingly well-designed, for the most part. It will be interesting to see how well it starts an engine as that will mostly depend upon the quality of the cells. Any Chinese power bank that will supply over 3A to the USB port while maintaining 5V is already above-average. There do seem to be some components missing from the main PCB, but they don't seem to affect the advertised functionality.

[@AngDavies]

The two black wires and two red wires, could be a sensor/power ground kind of thing- while charging there is some voltage drop in the wires, so it's hard to get an accurate reading of the battery voltage through the cables used for charging. So they run two extra wires just for sensing the voltage (the balance wires have much lower current so don't matter so much) 4 wire measurement

[@jp040759]

Great teardown. You covered everything. Thanx

[@radekt.7843]

[@Jordan-qq9mg]

Great video! I loved you reading the manual and taking the time to find data sheets on several components. Not trying to downplay the quality of this product but one thing to note- the data sheet on the two MOSFETS inside of the black box on the jumper cables states that those numbers are for the components mounted on a large heatsink. You can bet those bad boys are gonna get toasty carrying 250 amps. Nobody come at me harsh, not an electrician by any means but I am interested in these types of things.

[@ac0rpbg]

that is the design. one of those chips most probably has over temp protection that triggers when they get too hot cutting the voltage. The idea of this boosters is to boost for like 3s and cut power. They are protecting the battery cells as they are not designed for 150c continues power, and that is what is drawn at 500A from 3000mah cell. But the reality is that this battery pack can't provide that so this booster will never ever provide 500A.

[@MuhammadDaudkhanTV100]

Really good ideas and good work brother

[@FerrybigGaming]

With those things, typically the mosfets are closed when it is plugged in, until it detects a battery. Once it detects a battery in the correct orientation (or the factory button is held), it turns on the mosfets

[@d.m.3259]

Funny when people say they have Cats. In fact Cats have servants.

[@RoaldKoger]

I've had this power bank / charging booster for a few years now and it actually did start my car when it had a flat battery. By bypassing the USB circuit you should be able to charge much quicker since lifepo4 can be safely charged at 0.5C.

[@KrotowX]

I'm thinking about purchase of similar device. Seems reasonable to do quick mod to charge internal LFP battery faster from my hobby charger in LFP mode.

[@TechGorilla1987]

Good morning (from Pennsylvania) Mr. DiodeGoneWild!

[@blubbspinat9363]

Wow, this looks like it's well worth every penny. LiFEPO4 cells obviously are more expensive that Li-Ion but are safer and putout insane amounts of current. They can also last much more cycles. It might also come in handy for a low power ham radio portable setup :)

[@KrotowX]

That is. Also I see whey they didn't used LiPo batteries. Those have even larger energy density and voltage. However are more expensive and prone to thermal runaway. Because of that LFP is obvious choice.

[@blubbspinat9363]

@@KrotowX also it is much closer to lead acid than regular li ion. With 3 cells you're too low and with 4 you are too high. 4 cell lfp is just perfect.

[@electronic7979]

Very good review video

[@stig44]

Now that's is review and inspection :)

[@ebinwaitee]

How these usually work is they sense the voltage from the battery and you need to have at least like 1V worth of charge in the battery for it to activate the jump start. The button labelled "Factory" is probably for QC testing of the product just before it's put in the package

[@mrchuck21521]

From what I found out you have to have certain voltage range. This prevents connecting overdischarged batteries, cause if you would charger would send full current and overdischarged batteries might crack when taking in too much amps.

[@keithking1985]

if it is using the same coil for boosting & bucking, can you used it to charge your phone while charging the pack it's self?????

[@thearchetype9829]

[@Mavi222]

I got this one, my car battery is dying slowly, so sometimes I can't start the car in the winter. This works really well! (yes I know I could buy a new battery for a little more but.. Good thing to have in the car even when you buy a new battery.

[@poptartmcjelly7054]

A 53Ah battery is only about 50€, i don't see why you wouldn't just buy a new battery.

[@AmitabhAnkur]

This is for emergency purpose. When battery voltage is low. There are some supercapacitor versions which charges from battery and provide high current if battery is old and it's internal resistance is high.

Nice video , i am amazed how the tiny legs of the transistor can Handel over 200A and don't act as a fuse . 11:50

[@grooveindia9989]

lol

[@grooveindia9989]

there is no fuse in a Chinese device because THE DEVICE IS THE FUSE

[@therealovy77]

They are used in every circuit with pulse current, not continuous, so the power dissipated is less... And, as he explained, the drain current is limited by the transistor's internal temperature, so if the current rises, the dissipated power rises, internal temperature rises (the heat radiator to dissipate the maximum power should be immense), and current will decrease, so no chance to die like a fuse....

[@royspeakman1157]

[@rolfsrolfs]

Could it charge each of the cells in a controlled paralell, so it would not need to boost the input power to 12v for the full serial of the battery?

[@lillydogpoo65]

[@superdau]

Thank you for the note about them all being Li-ion batteries. It is a pet peeve of mine when people call cylindrical cell "li-ion" and pouch cells "lipo" batteries. The form factor does not tell you what is inside. First as you said, they are ALL li-ion batteries. Cylindrical cells are just rolled up pouch cells. The form factor leads to different applications, and those different applications then favor one of the sub chemistries. Add to that, that real li-ion-polymer batteries (where the electrolyte is a polymer) haven't gotten out of the research phase. I guess some marketing guy heard that buzzword decades ago (some as it is happening with "graphene" batteries right now), and slapped it on a product's name just because it has a polymer (i.e. plastic) separator inside or plastic pouch around it.

I have a question sir! Battery is directly outputing 12v , if car battery backfired(i mean instantly backing voltage)to the battery,so it can damage the battery,so using diode is safer ithink❤️❤️

[@alanx4121]

better use some sort of breaker for polarity protection, than waste 150w. Which usb tester is good to buy? thanks for the educational vids.

[@teslacoiler]

At 12:03 the datasheet shows a reverse diode buried inside the MOSFET between the drain and the source, so there is any protection against reverse connection of the clips!!! ... this means that you can connect the jump starter to a good charged battery and follow the rule written in the manual (keep away from people and pets) :-)

[@eDoc2020]

That's what I was thinking (but btw this body diode is actually in all MOSFETS). Hook this up to a 24v truck and interesting things might happen.

[@waltercomunello121]

such a large current (100-200 or even 300A) needed for the starter engine coming out of a 12V 3000mAh "lithion" (my own naming) pack all of a sudden? aren't there caveats here? am I missing something?

[@JessicaFEREM]

man, if you were to follow all manuals to the tee, you'd be wearing a hazmat suit with 500 layers of bubble wrap all the time

[@arpir97]

This LED lens is actually kind of : Total Internal Reflection (TIR Optical Systems) is a phenomenon in optics, by which light experiences complete reflection at an interface between two media. Most optical fibers prism in binoculars use TIR as the guiding principle.

[@eDoc2020]

I wonder if the LiFePO4 battery has a built-in protection circuit. It would probably only protect the low-current output though. Maybe that's where the 8A limit comes from.

[@gabest4]

If the input 5v is boosted to 12v+ how does the balance changing work? Where are all those 3.3v are coming from on the colored wires?

[@DiodeGoneWild]

there is no balancing transformer, so it probably just charges all in series and bleeds some current from cells that have a higher voltage.

[@git-push]

Explosion hazard.. uhm..it starts to look intresting. 😂😂The best!

[@MorgothCreator]

Interesting, if I will see it in my country I will buy it, look pretty nice.

[@ChriFux]

I don't think the battery has temperature protection included near the cells. The many leads on the balancing connector are just because they used gnd and 12V twice to deliver the current of the 12V output

[@DiodeGoneWild]

Yes, I also came to this conclusion. 2 extra wires would make sense as a temperature sensor, but it just uses double wires for the overall positive and negative.

[@DynoRC]

It's DiodeGoneWild, the worst nightmare if every manual writer 😂✌️

[@rickhuntraslam2925]

You've never been to the K-MARK

[@tscherenkov9461]

They bottom balance the cells because the high current output can not be switched off based on individual cell voltages. The electronics in the high current wires can only determine the low voltage cutoff with the combined packs voltage. Bottom balancing the cells to the cutoff voltage is the workaround. As long as the cells stay bottom balanced no individual cell should be discharged to far based on pack voltage alone.
