I used it to get the car to the shop to have it fixed. The jump box did just that with a dead battery. There was an incipient drain due to a program issue( Ford issue that reared its ugly head). The car left me at the post office with no way home.

Haven't had it that long, jump started 4 cars, motorcycle, still at 100. Works great. Just don't tell anyone you have it, I've been getting calls asking for jumps lol

This jump box has yet to fail me. It is quite heavy but that’s okay with me. If you’re buying a jump box this is the one to get. I had one from HF that is totally junk and caused me a ton of trouble.

This jumper is a strong little beast. I was able to jump my brushhog and my gas generator easily. This will come in handy when the power goes out and I am in need to start my home generator. The unit is easy to use and to recharge. Highly recommended.

I bought this JNC 5 years ago for the reason I don't remember but I haven't used it ever since. But this morning, my vehicle didn't start even after repeated trials. So I brought out JNC-660 from storage and started charging it. To my surprise, 1-hour charging was enough to start the engine in my car. I didn't expect this product would last this long.
