500A Car Jump Starter from Lidl - unboxing and teardown 

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

Before I got myself a hot air station, I used the high beam of a broken H4 lamp @15V for SMD desoldering. I just had to put on sunglasses while doing that.

*Keep away the device from people* The user: I CAN'T USE THIS THING RIGHT NOW BECAUSE I TOO CLOSE WITH THE UNIT!

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.

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.

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

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

Excellent Technical level very useful English is easy to understand with your accent I love this accent Many thanks for your work

I love your accent! Very uniquely different yet easy to understand…..Subscribed!! ✨💯

Bought one for like 400kč on local street market... and it's awesome :D it has rubber covers for ports, USB-C for input and quick charge as powerbank

Nice video! I'm excited for the induction cooking plate :3 i recently took the old one from my mom apart since the touch panel wouldn't work anymore. It had a big crack all across and hot water found it's way into it. Every component still works though

Great teardown. You covered everything. Thanx

And of course I plan to go to sleep but take a look at RU-vid subscription feed and inside of it there's an interesting video from Diode gone wild :) Great video as always! Thanks

Jump starter, just what I need. I find it so hard to get started. ;)

Seems to be a nice unit. Excellent tear down.

Those two HY4903 are N-channel MOSFETs.Nice video 👍

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

tankyou my master...mr dioda is very genius...

Those chip s are like vrm s on new computer motherboard . Good video

An excellent and joyous vid - thank you.

You're English accent is awesome

Merry Christmas Diodegonewild :-)

Really good ideas and good work brother

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.

Good morning (from Pennsylvania) Mr. DiodeGoneWild!

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 :)

Not a bad product, much better than I expected. Might even be safe.

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.

Spray contacts and tighten them by bending spring contacts on usb meter, it helps.

Thank you. Good review.

Now that's is review and inspection :)

i wanted too see at least a 200A test load thank you BTW

for the led indicator put behind the plastic a transparent black sheet like piece of x-ray . nice video

First of all thank you for doing these videos in english and I would really like to know what the wrappers on the individual batteries look like.

Thanks buddy... Love your content.. 👍

Lidl has it actually in Germany stores and online. The high-power battery connector is a EC5 connector.

It's a powerbaaaaank so faaar. Thaanks for the reviewwww

Have one, it works, simple!

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

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?????

Very good review video

Another good video, and thumbs up for your last chance reading cat! ^^

good teardown

Your cat seems quite curious..😍❣️

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.

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

Great review, are you happy with the portable oscillosope? I am looking for something like that.

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.

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

Plz explain how to bypass the security of induction cooktop coz i am planning to use it to make tesla coil. But unable to bypass the security of it. Plz plz help

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

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

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

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❤️❤️

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) :-)

hello great video i have bestek jump starter that stop work it only work if i plug it to the wall plug what is the problem?batteries?pcb?or something else thanks

HY4903P mosfet looks very suitable for your ring tester...

Video super děkuji za něj! Mám tuto krabičku taky objednanou, ale díky České poště, která balíček od LIDLU převzala už před týdnem ji ještě nemám. Je tam i nějaká BMS? Pokud by nebyla, bylo by pak teoreticky jedno jestli ty baterie nabíjím (náhradním konektorem) pres výstup ENGINE START digitální (modelářskou) nabíječkou ne? Pokud je tento konektor stále pod napětím a napojený přímo z baterek v sérii, nevyděl bych v tom problém. V případě potřeby by se takto dalo nabíjení urychlit, co myslíte?

The LED lense called TIR lense, totally internal reflective. Exactly as you described.

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?

I like watching videos by diode gone wild and I like the safety warnings I take those warnings seriously I wish to see a video about the Pets of diode gone wild like the cat and a dog I also wish to see longer videos close to a hour ?

Get two metal (preferrably steel) buckets with sand and something out of steel to grab stuff. Or use ceramic plates to move the burning stuff into the bucket of sand and have another one ready to shovel sand onto the burning stuff.

7:16 Haha, made my day :D

Helo my friend thanks a lot for this awsome video. Greetings from México.

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.

The transistors can only carry max current with a infinitely large heat sink. It just looks good on paper.

I do appreciate it :)

Just an amazing accent. Nice content too!

Brilliant !

But what's about capacity measurment? I was thinking that it will be in this video. Hope you will test it out in the next video about this device

It looks like a really good quality Car Jump Starter/power bank.

there is a 80A 14VDC relay instead of 2 mosfets in umap 12000 c3 version (also no button on battery cable unit)

This is the best component at your channel lol.

Great autopsy

this must take forever to charge, I'm suprised it doesn't have a bi-directional barrel jack where you could charge through it and use it as a 12v output. i have a bank that cost like $10 and did that

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.

fajne sprzęty. interesuje mnie to jaki akumulator 12V tam w środku jest. To CAŁE NIEBIESKIE> ogniwa 18650 tam są?

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?

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.

Nice one !!

i love the way you demonstrate it is attractive and funny.

I would like to see a Cold Temp Jump Start test with this LiFepo4 Battery.

I have something similar but the battery died. I pulled it apart and now use the PCB to charge Lipos for my drone.

I heard this device has very high self discharge. You need it recharge almost every week because after a week and more it lost almost all power. Can you check this phenomen?

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

What is the vapour/smoke coming out from bulb. 18:18 Happens with me also whenever I run these types of bulb overvoltage.

great info..im using my bank to power my RC tug boat that is in parrallel with 3 -7ah gelcells, it screams aT full throttle . the 3 gel cells are mainly for ballast, twin 3" screws and 2- 12v tire inflator motors. cheers from the states. Hey kids don't try this at home without adult supervision...HA yeah right

Half an hour and no car to be seen... so does it actually work?

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

Danke!

perfect for powering 12 V HAM radio transceivers

Looks like Lidl has a lot of neat shit. They just opened one by me. Have to check it out.

Love from india.. Can you pls make a video on smps design calculation.? Thank you

Can u take a look the inside of the charger ?

I am just thinking are those battries are able to suppply 500 Amps🧐🧐

Sir power diode ke paller me resistance capacitor sunbber curcite me resistance, capacitor ka value kase nikale pl. Video kanye

Meh.. I'm jealous. I like stuff with LiFePO4 cells in it. I already have such device but mine has a Li-polymer in it. And it needs to be charged with a weird 15V adapter. It has the usual 5V USB, a 12V output and a 19V output for laptops. Mine also has a protection box in the start output. I didn't check what's in it, yet, but it it's bigger than what you have. So, I think, mine has a relay in it. Since yours is LiFePO4.. can you check at what battery voltage / current the circuitry stops charging? The high-current output is a male EC5 connector, which should be female. I made a converter cable so I can use mine to power anything. I use those EC5 connectors quite a lot.

HI am a little skeptic on the starting curent and ability to start Diesel 2000cmc engines (which typically need 400 - 500A cranking amps to start). I don t understant how can u make starting current of 500A from a 12V 3Ah lipofe4 pack, capable of delivering nominal 3A @12v. This mean like 150C overcurrent rating (500A/3A). I used a lot of Lipos for RC models and never come across on cells that could deliver more than 48-65C and there were like high spec cells. So say 65C x 3A nominal curent = 195A starting max. curent. That is still a gap to the 500A advertised. If you put the 4 cells in paralel to give 12A it might get up to 500Amps but at the 3.2V (since cells are in paralel) which also might not start the car as you do not have the 12v needed for the electronics (ECU) etc. So i believe such a starter pach should run a minimum of 4 cells in series to total 12.8V and @ 20Ah capacity per cell to be able to produce the 500A at an average 25C rate of discharge. Any way to make sure you need like an old fashioned batery tester (w/h power shunt resistor and relay) to test what is the short circuit current for this pack.

i got similar one for my car,but it has few super capacitors.not sure why

after few minutes my ears starts bleeding :D
