Who It's For

This jump starter suits drivers who want a high-capacity, multiuse portable power pack that handles larger engines and also charges mobile devices. Small fleet owners, boaters and RV users will appreciate the 3000A peak rating and the ability to power 12V devices.

Those who need a lighter, simpler booster for occasional use on small motorcycles or compact cars might prefer a smaller, less expensive unit. Also, if extreme long-term storage without topping up is required, users should plan periodic recharging to maintain peak performance.
