Customer Review

Reviewed in the United States on October 17, 2017
Amazing - jumped a dual battery Humvee H1 with completely dead batteries that has been sitting for 2 months. I connected it and by the time I walked around to get in and start - it was turning over fully. It took 20 turns (fuel related) then fired up. When I brought this genius boost it home to charge it - it was still at 75%.
