Utrai 2500A Car Jump Starter - unboxing and teardown 

A compass and wireless charging? These things keep getting more and more functions. Maybe the next one can fix my broken heart

"4 skrjus" 😂😂😂🤣🤣🤣, I love his accent in english 😁😁

13:20 AON7544 N-FET. You can see the 3 source pins connected together next to the gate.

Another video from a lovely engineer with all the important points and wonderful descriptions and complete schematics.I learned a lot thing during the few years I was joined this channel and thanks for everything 🙏⚡

Thank you for displaying the chips which are used! I'm working on a DC to DC power supply with isolated output and this is very helpful for me...

I love your videos, Diode, I'm a long time fan of your channel, since you made that first video of you putting "Even more saaaaaaalt!" On that glass with water and the dodgy water heater

Wow, it opened up and that was wayyyy more electronics than expected.

"Of course if you're interested in just the unboxing you're watching the wrong channel"... No, I think I'm exactly in the right place :D Seriously I love your videos, they've taught me lots over the years, and that it doesn't matter what way you do things, so long as they work. I've never seen someone solder like you, but it certainly gets the job done! Love the channel

Thank you DGW. Stay safe and God bless you! 🙏😊

thank you sir, always love teardown video

Seems surprisingly well designed and built!

I don’t know what to say, this guy knows his trade but even then his very funny, I’m not sure if his doing this on purpose or that’s how he is but either way god bless this guy, his straight to the point, no messing around wasting people’s time etc!!!! Bless you brother ❤️👍!!!!!!

Very well explained

I'm fed up with so many test consisting to take 12 minutes to plug a jump stater and say "it work ! So I recommend it". I'm very happy find a serious test like yours. The part about different cells configuration was very intersting.

We can see everything in action at 50FPS I am really happy you now know USB-C

The perfect czech experience - watching DiodeGoneWild with Zatecky Hus ""fire extinguisher" :) Bloody hell :)

I would like to have such a device thanks for the review!

I bought one of the 2000A version, itdoes really work Very well. Able to start 4liter diesel engines as If It was a small motorcycle. Then I bought another one to my father.

Nice review video

Waiting for next video 😊😊

My truck battery went bad last week and I’ve always wanted one of these jump starters but never bought one. I had to use my two cordless 12v drill batteries and put them in series, tape them together, and jump my truck off of that. Just wasn’t enough power without putting them in series, the Hitachi drill batteries weren’t happy about it but they survived.

Nice unit.

nicely balanced, you rarely see batteries identically charged.

I'm not here for the unboxing, I am here for substructions and diminishions!

You are the best electrical engineer I have ever seen! Keep going!

Very Nice...

AHH .... waiting for your video from long time

I am always amazed that tiny cells like those manage to start any car, but they do :-D The weak point is the battery clips, very crappy and minimal surface contact. A frend had a similar unit with those clips, the plastic melted on one side because the other side was not actually connected to anything!! :-( I fixed the melted side and added a thick copper loop cable so both sides did something. (on both clips). Sorry but your cat is loverly :-D

The usb output voltage is surprisingly stable

Nice ❤️👍🏻

yesterday I watched a video by photonicinduction from 2015 about one of these things, I think it was when they were somewhat new and it made me realize how powerful these things are. Like, drawing 600 amps (peak of course) from a box not much larger than a phone is really amazing.

2:50 They misspelled Charging as "Charing" XD

Nice review - would love to see if that battery pack is still rated at 88Wh, or whether it can actually pull 88Wh from the battery... ;)

Looks like a pretty nice device. That company Thieye make action cameras, so possibly it's made by one of the bigger Chinese companies that actually have to care a little bit more about quality.

I hoped you do a 2500 A test :-) These connectors will never ever handle a current of 2500 A! Maybe for 1 ms if at all. Cables and connectors will melt in secs!

At 2:43 it says the dual USB & type-C outputs are for charing. I think they meant charring, so maybe there will be a fire later on!

What's inside the jumper cable assembly? Just a bunch of capacitors or anything else? Would be interesting!

Where was this jumpstarter sold? I went looking for it on eBay but I couldn't find it! This one seems to have a lot of the components that I need for another project...

i hope you make a video about explanation and schematics for 50 A 12 VOLTS PSU

Maybe I missed it @DiodeGoneWild, but in what sport do you compete? I know you have many medals and travel frequently.

I need to borrow your warning message for my channel....haha I'm still waiting for a video in which you dont use the word "probably".....i love your videos....

The component at 13:17 is an AON7544 MOSFET from Alpha & Omega Semiconductor.

Almost forgot about the emergency hammer on the end of the pack because if you hammer anything other than glass you will have an emergency on your hands.

Please do a video on "Old VCD RF" module with schematics. I would be glad if you do so.

Pretty nice charger but is there any battery protection? Can the car jump connection pull the batteries below safe voltage?

This GA8Z6A is a transistor and not an IC, the identification labels on the board help to identify which type of component goes in place, this PCB identifies ICs as U and transistors as Q. Probably due to the connections it makes, it should be used to disconnect the USB buck regulators in case of an overload or simply to turn them on when pressing the button.

Niiiiceeeeeee!

The unknown chip, 7544 GA8Z6A appears to be a dual channel mosfet, the gate should be 1 pin, and the collector drain should be doubled up (as 2 mosfets in parallel)

Many features, but will it start a car?

Very good beauty!.

The wireless charger coil is assembled in the opposite direction. Should be coil up and ferrite back layer down.

thadits nyyyyycee

I wonder how much it would cost if I wanted to ship you some thing? I have a lot of excess test equipment, I’ve accumulated mountains of the stuff. when I got started the only way I could afford professional quality high end gear was to buy broken or untested equipment and repair it myself. As I got better and build a fully stocked lab… (with Mostly NIST traceable calibrated equipment)… I didn’t have to look for gear any longer. But It started finding me. Because After a few years of looking.... everyone knew that I wanted the stuff so they would tell me about sales and auctions and things. I’v bought entire pallets of hp and tektronix equipment and stuff like that for pennies on the dollar. A lot of it is nice good calibrated equipment… mostly from government auctions in my local area. I live in an area with huge government industry and a big history of government involvement. Nuclear and otherwise. Home of the atom bomb.... So there are storage units and warehouses full of test gear all over our tri-state area. So I’m always looking at auctions just for fun. But most of it just not worth selling on eBay because of the shipping cost. It’s not worth selling a $400 scope if it’s going to cost $200 to ship it and there’s a good chance it will get broke. Then you have 12% eBay fees on top. So I would be interested in sending you some pieces. Especially if there are things in particular you would like to have or upgrade some of the things you already use. Just not sure how much shipping would cost and the cheapest way I could get it there. Another one of my buddies owns an industrial scrap yard, they’re always bringing beautiful industrial electronics, motor controllers, and every type of industrial electronics toy you can imagine in that place. A lot of medical stuff to like x-ray machines, even scored a few surgical lasers. If you want some stuff for teardown I could ship you a bucket load of the stuff if I knew a cheap way to get it there safe and in a timely manner. I salvage what I can but they’re not open to the public, and I’m only allowed in there because he’s my buddy. BUT I CANT KEEP EVERYTHING … I tried that for a few years and it almost ruined my life. It’s hard to watch a $2500 industrial motor drive get crushed… But I can only do so much. I can’t keep everything so I have to watch him crush thousands of pounds of beautiful like new industrial electronics every month.

Do you advice this battery. Does it worth its costs?

Gdzie przechowywac taki powerbank w domu / piwnicy ? Czy nieuzywany moze kiedys mu odbic i sie zapalic / wybuchnąć ?

hey diodegonewild... please get displate as a sponsor just so you can make the ad spot!!!

Hello, I found an electeonic load on your website, i make that circuit properly, when i connect a battery, the circuit is working perfectly, but when i connect a 12 volt 15 amp chinese SMPS, then the mosfet keep blowing or shorted... i dont know why, i used IRFZ44N mosfet, 7.5 volt zener, 100k potertiometer, 1k 1 watt resistor.... can you please reply or suggest anything? and sorry for my bad english....

Was this the donation from Lithuania?

how do these give 2500A at 12V what's the core circuit for that 2500A.

You should do the jstar5 that dam thing is a struggle to actually charge wonder why it does that

still not popular but very fun to watch

I would be a bit reluctant to poke a metal conductive screwdriver into a PCB connected to a massive 4S Li-pol battery capable of delivering hundreds of amps. :)

17:10 exactly :P

My experience with these jump starters: You need one when you don't have it. When you have it, you'll never have any use for it. When you do have and need it, the charge isn't high enough for the jump start😂 All the ones I've tried had only three battery packs, this one should have enough juice... Hopefully.

i have similar model, it charges very fast to 100% but charger is disconnected devices indicates 56%. Is the problem battery cells? What is the model name of the battery? Thanks

Какая реальная ёмкость аккумулятора jump starter?

From what ive seen of these lipo based jump starters they tend to explode under a extreme engine start attempt.

I have an idea. I want to ban all lead-acid batteries from my vehicles. Is it possible to permanently replace a lead battery with a Jumpstarter?

But what about the scemaatiic?

Battery Lifepo included.

Here is the manueeeeeelllll

Those output cable inside look awfully thin to carry 2000 amps. Think how thick your jumper cables are. Of course the whole lead length is much shorter so maybe OK? When I have dead battery I get a good battery hook it up with jumper cables . NO electronics required. All the electronics in the unit just to regulate the charging and the accessory outputs.

The cat is very angry !

I need one of these so badly, my car is older than me 😩

So we're looking at...4 × 32650 cells? They're selling on ebay for $35.00 per piece.

New "trend" to shovel in wireless chargers (a.k.a BIG Energy Waste) to everywhere just sickening. Ugh..

۲۵۰۰ amps? Isn't it too much?

How can it produce 2.5kA? How thick do wires need to be to carry such a high current? Are you going to test it on a car?

Please give me a welding inweter cerkit diagram

13:25 it's just a n-channel mosfet. AON7544

Здравствуйте. Я не понимаю по английски поэтому скажите, стоит его покупать или нет?

3:52 why I think that car is a tesla model s?

You didn't check the PD output

so, now start some car in some next video with it

if you ever need the compass, you're f'ked 🤣

How long? Bloody Long

adam bizim keçecililer gibi konuşuyor

What would happen to a battery like this if it's left in the glove compartment or the trunk at -20ºC?

It doesn't say wireless charging, it says wireless CHARING. Does this mean we can grill with it too!?!

it looks like gooloo

7:00 it is bit too high voltages for car electronics. Some dodgy car electronics can start smoking by these voltages 10:50 no way these can deliver 2500A, these not super caps... Even 25A is way too much to ask. I used super caps and 10xAA batteries to start the car. 5 series 2 parallel

Is this an Italian or Russian accent? Who can tell us what country's accent this is?

Senseless crap options. Why would anyone use this for power pack. Keep it for emergency car jumping ONLY. Marketing wank. Crap just to boost sales. Most folks are lazy and not diligent enough to keep it fully charged for car jumping. Great video analysis.

3:52 Car diagram shows a Tesla Model S Why would you want to jump start an EV? The battery packs would not be at the same voltages and would most likely destroy the jump starter as a typical EV battery pack sits at 300-600V DC

it has charing not charging

Sad kitty

where you get this accent ?😁😁😁😏😁😁

You talk funny.

It's Charing instead of Charging !
