Versatile! Compact!  These lightweight portable Jump-N-Carry units are extremely versatile, easy to use, and capable of providing a stranded motorist with ample power to start a vehicle with a low or dead battery. Industrial duty clamps penetrate corrosion on battery terminals, making jumps easier and safer.   Powered by a 18 AMP Hour sealed maintenance-free internal lead acid battery, the Jump Starters supply high cranking amperage voltage to start your vehicle.  Internal chargers replenish the power once the unit has fulfilled its task.  Carry one of these in your trunk and it will never leave you stranded.
