Bests & Worsts Reviews from Amazon

Charged the Jumpit for 40 hours, like the instructions said. Tried to jump a Nissan Sentra 1.8l...It didn't work. Recharged Jumpit. Tried to jump 3 different 4cyl cars over a week long period. It wouldn't start ONE....not even CLOSE to being able to start any of them. Says it can jump V8's...I doubt it. I was able to start ALL of the vehicles with regular jumper cables and a Honda I4 and Nissan V6. Just a HORRIBLE product that doesn't do what it advertises. I have tried to get a refund, but they seem to run you circles.
