If your J1772 charger's cable falls short of your EV's port, this 21 ft extension cord adds the reach you need without having to reposition the car. It works on both 120V and 240V circuits, so the same cord handles a standard home outlet for Level 1 charging or a dedicated Level 2 station, good for daily charging or trips away from home. Rated for up to 48 amps, it is built with heavy-gauge copper conductors inside a fire-resistant, IP66 waterproof jacket that keeps working from -22 to 122 degrees Fahrenheit, rain or shine, summer or winter. The PC and ABS housing with a copper TPE core is engineered for repeated plugging and unplugging, and an ergonomic grip makes handling easier in tight spots. The kit includes a carrying bag for storage, a cleaning cloth to keep the connector dust-free, and a cable tie to keep the cord organized.
