Antigravity Batteries 2000A Jump Starter – 12V Lithium Battery Booster Pack, Portable Jump Box, for up to 10.0L Gas & 8.0L Diesel Engines

Waited until I actually needed this and used it. My '99 Dakota wouldn't turn over because the dome light was left on. Easy to hook up and worked to start the 318 cu in/5.2L truck engine right away.

great jump pack

Initially skeptical but so far, this ANTIGRAVITY Handheld Lithium Jump Start has performed 100% with No Disappointments. ANTGRAVITY Product was Highly Recommended to me by a trusted friend in the Exotic Car Business. I can also Highly Recommend ANTIGRAVITY Products today. JM

Works well, but hard to store. Suggest not letting it freeze.

I did not get to use it for real, but it is solidly built, read-outs are clear and it is a hefty battery which holds a large amount of charge. All functions other than jumping a car work as described.

Does what I need, it’ll jump a car even after the pack has been sitting a while, and it has been in my carryon luggage and I had no issues

After it arrived, I charged it overnight. Then I placed it back in its original bag and then into the original box to keep for emergencies. It remained in the garage for several weeks. It was never dropped or exposed to water or excessive heat. I had the occasion to actually use the jump starter and it seems to be dead. Lights don’t come on when I turn it on. I tried charging it but nothing. Very disappointing. I contacted their customer service through Amazon, but no reply. I requested a return through Amazon from the company and after several days no reply. Would avoid this product.
