Lost a120V AC power cord for recharging a (jump Start) power unit.?

Question

The JUMP START Power unit, 900 peak Amperes/400 amperes starting power, solid-state, automatic operation and circuit protection. The built-in 120V AC recharging circuitry has an automatic cut-off to prevent overcharging. Original power cord lost, want to know what other type cords can be used. I have several cords that may work but I do not know how to tell. The cords have a plug to go over or into the unit on one end and have a big black square box plug on the other end to plug into 120V AC wall socket.

Answer 1

Pilgrim:  Your description does not make sense.  What do you mean by, "The cords have a plug to go over or into ..."  Are you talking about the cords you have or the cord you need?  Please edit and clarify.
