First-timer, instructions could be clearer
"I followed the clamp instructions carefully on my first try, and the gasoline engine started right up. Instructions could be a little clearer for first-timers."
— Carlos (4/5)
Fits in my motorcycle's seat compartment
"After my motorcycle battery died before a ride, this fit right in the seat compartment and started it up."
— ROBERT (5/5)
Jumped three family cars, one charge
"I've used this on three different compact cars in my family without it ever needing a recharge between uses."
— Andrew (5/5)
Even jumped a riding mower battery
"I jumped my neighbor's riding mower battery of all things, proving it really does work on more than just cars."
— Timothy (5/5)
Skips the trunk, lives up front instead
"This lives in my glovebox instead of taking up trunk space. Jumped my car and a stranger's in the same parking lot. Cable is a touch stiff at first."
— CHAD (4/5)
Boost jump started the old truck
"Old pickup with a tired battery. Boost 400A started it reliably all winter."
— Isaac (5/5)
Still had juice for a second jump
"There was NEVER a doubt it had enough charge to jump a second vehicle that same afternoon."
— Martin (5/5)
Never expected it to jump a boat
"My boat's battery died at the dock and this jumped it, something my old car-only jump box could never have done."
— Argam (5/5)
Twelve jumps in, spec says twenty
"The spec says 20 jump starts per charge. I'm at a dozen uses since my last charge and it hasn't slowed down."
