A portable EV charger works by safely converting AC power from the grid into a controlled current for your vehicle’s battery. The internal control box manages power flow, monitors temperature, and prevents overcurrent or short circuits. Simply plug one end into a power source and the other into your EV’s charging port. With amperage settings from 8A to 32A and output options from 2.8 kW to 22 kW, Voldt® chargers ensure secure, efficient charging on single-phase or three-phase connections.
