AVAPOW 10000A Battery Jump Starter, 40000mAh Car Battery Jump Starter for All Gas or Diesel Engine, 12V Jump Box Battery Jumper with LED Display & LED Light

At 100% capacity this jump starter is Suitable for multiple car battery jumps-boosting. Mine was also used to maintain battery power for a 1 minute drive to safe location when car alternator had stopped functioning.

This unit is a little powerhouse. I own two other battery jump packs that usually get the job done but this thing really kicks out the amps. I recently had a situation where I had to use both jump packs on the same vehicle just to get it started. I use this jump pack on the same vehicle by itself and started at four times and used less than 15% capacity. very happy with the purchase well worth the money I would highly recommend it.

It looks OK I haven't had a chance to use it yet. My battery is still running in my car so I haven't got a chance to use it so I guess it's OK. It seems like it'll be a good battery jumper starter, but I guess sometime in the near future or next winter, I'll get a chance to use it.

Delivery was super fast. Then I tried it to jump start my Mercedes Benz Diesel Van which has been sitting dead for over one year and it came back to life. The van is a one start after then.

With a whopping 40000mAh capacity, this jump starter breathed life into my dead battery within seconds. It's a powerhouse that every vehicle owner needs.

excellent jump pack. lots of power. highly recommended.

I hooked it up, almost blew myself up. They put the black with the red should be in the red or the black should be.

cables could be thicker, maybe 0guage, but i did start my semi truck with it. however if the batteries are extremely dead, or bad. the wores get too jot and will melt. my unit started melting the wires, and now incant get the adapter clamps off. so i just leave it connected.

I use my jump box daily, so far this one seems to be great. Have to wait and see how long it lasts. But love it and recommend it so far !!

Unit showed 63% charge when unpacked. Followed directions to charge for min. 3 hours prior to use. Charged overnight. Couldn't even get flashlight to function .Panel showing zero (O)% charge. Is it possible that is a reason this item was so drastically reduced in price???
