Our portable power jump starter includes an internal charger. Use a household extension cord (18 AWG or larger) to power the internal charger. Once you plug the extension cord into an outlet, connect the cord into the receptacle on the unit to charge.
We suggest charging your portable power jump starter’s internal battery immediately after you purchase it, every 30 days, and after every use. Frequently charging the battery maximizes the power potential of the unit and ensures your unit will be ready whenever you need it. Keeping the battery fully-charged can also extend the life of your unit.
