The Dakota Lithium Powerbox+ is a waterproof and universal mobile power station, including the juice to jump-start a car or boat engine. The Powerbox+ 60 and Powerbox+ 135 offer over 1,000 cold cranking amps (CCA) of engine starting power! Or, use the Power Box Plus batteries on high amp missions to power 12V trolling motors. Each model also supplies the battery to power personal electronics through two AC wall plugs and 4 USB charging ports. LiFePO4 technology translates into batteries that are half the weight of a lead acid battery, with the amp hours to last longer and provide more power. The PowerBox 60 contains the DL+12V 60Ah dual-purpose battery has twice the power and lasts 4x longer than a lead acid battery; the PowerBox 135 holds a DL+ 12V 135 Ah battery with 5x the power and lasts five times longer than traditional batteries.
