  1. 5 out of 5

    All I can say is “Wow!!!” I own the JumpBox 400 and the JumpBox 1000. Both of them are incredible products. Period. This little thing is remarkable. The JumpBox V6 Pro 400 is one of the coolest “must-haves” I seen. It redefines the term “two-for” device.

    This little monster will jump up to a V6 engine (I ended up jumping off four different vehicles this past winter)… AND it’s small enough to fit in my pocket (about the size of a wallet) to charge my iPhone multiple times. It comes in great carry case, complete with detachable Smart jumper cables, USB charging cable with multiple device inputs (USB, Micro USB, Lightening/ iPhone 6 and up, old iPhone 5 and down/ iPad, etc.), a wall charger for the unit and a 12v/ cigarette outlet charger for the unit.

    I literally use this several times a week to charge a myriad for devices… and it will jump most midsize vehicles. What’s not to like? I’m an avid cycler, mountain biker and backpacker. It’s utility and light weight have caused me to make this a part of my gear list for every outing. What’s not to like?

    Do yourself, or a loved one, a favor. Pick one of these up, because the safety (ability to jump a dead vehicle battery) and utility (charge a gamut of devices and small enough to comfortably fit in a pocket or purse) are unmatched.
