I used mine, a half-charged, small-capacity unit, and successfully jumped my Dad's 3.3 V6 minivan. Having never used one or have seen anyone else use one, I had my doubts but color me impressed. These things work and are VERY handy.

I have a similar one and it does work great. The one thing I hate about it is the small clamps.

I'm surprised they don't have over current protection and would blew the battery inside. I'm not keeping that thing around in my car.

Amazing, same batteries that power my RC airplanes. Would have never thought they could jump a car. We have a 1000a one at the shop, no name from amazon, just as our own test, and it has no problem with V8 BMWs or their 6s.

I've been happy with mine. I keep it charged in the van and have used it a few times.

I top of the charge on mine every 3 months. It lives in the trunk of my car. Never used it but it's nice to have. Can also serve as a flashlight, warning light, and USB charger.

very few of these things are good for more than a slight assist.
the one in the video is very common being rebadged for dozens of brands.
a neighbor bought one to keep in his v8 chevy pickup.
he asked me how to test it to be sure it will work when it is needed.
disconnect the battery and substitute the jump pack.
it gave about 2 very slow turns then popped open and smoked.
repeated the test with my jump pack which has heavy copper cables and clamps and a 17ah high rate ups battery from enersys.
truck started like it does on its nearly new battery.
if the jump pack cannot start the vehicle you got it for without a battery expect to be stranded if your battery has failed rather than been discharged!

Although lithium ion batteries have great energy density, they also degrade the fastest when left fully charged. I would suspect that this pack loses a lot of its potency after just a few years unless the user knows to store it at 40-60% charge. Which is kind of inconvenient for this application.

I just bought the GB70 model to give my '06 TDI the extra it needs to start at -30 to -40C. It will turn over the completely cold engine with enough speed to get it to start after a few attempts have built up enough heat in the cylinders to get it to run on its own (probably a good 30 or 40 seconds of cranking over a minute or two). The stock lead acid will only do it if it's been on a proper battery charger overnight (not the NOCO maintenance charger I got to keep the snowmobile battery happy which doesn't seem to give as full a charge).

So far so good but it's only been a week so how long it lasts is a big question.

Yeah being a cheap Chinese one that I have you are right. With other better branded stuff they will actually oversize the battery and then purposely undercharge it to extend its life for this reason.
