Airkoul 99800mAh Portable 800A Peak Current, Car Jump Starter, Black and Red

I had to jumpstart a dead car and it worked, but I have to recharge the jumpstarter. For never using one of these before, it was easy and convenient, great buy, great investment.

Can you just as described except?I thought it had a built-in airpump.I picked the wrong one but this one works just fine

my boyfriend loves this he is useing it far alot of different projects.

I like it very nice for the money

This jumper was purchased in Dec.2024 and has not been used. It is exactly the same as a jumper I purchased in Nov. 2024 that started 2 small engines instantly the same day with their batteries at 5 volts and the jumper volts remained a 16. When I went to buy more of the Nov. item in Dec. for presents, The price had been raised and it did not take. This review item saved me about $8 and it has a additional adapters so I purchased it and more. The compasses do not work well or at all on most but I don't care. Using the light is tricky but the different modes do work. The manual needs improvement. Follow the simple directions on the box and you will be safe with no sparks when making connections. The important thing is that they come charged at 16 volts and at least on one trial stayed at 16 volts after being used twice. T

Doesn't hold a charge as long as I'd like.

Bought this for my lawnmower-instead of buying a new battery every year. The power bank it the most complete and useful set of cords plugs and adapters that you'll ever need. I left my car sitting too long over the winter, the battery was completely dead, couldn't even get a dash light. With a 3.0L V6 I never expected it to work, but thought I'd give it a try. It cranked slower than normal, but started the car in approx 4 seconds. To me, this is a 5 star item - 1 star for the 99800mAh title lie.

The unit is seriously under powered. This size is more suited to a 4 cyl or riding mower. These may work on a V6 but not if battery is drained even 1/2. One may get a couple tries with this b4 it drains too much. Fortunately, once, it started after 3 tries. But not after that. AND YES, I had it fully charged b4 trying.
