All plug-In JuiceBox units are equipped with a 240-volt NEMA 14-50 input cable, which connects a JuiceBox charger to the wall outlet, and a 25-foot output cable with an SAE J1772 standard plug, which connects the JuiceBox charger to a vehicle. Our heavy-duty 20-foot J1772 extension cable will nearly double the reach of your charging output cable—a perfect solution for a garage with multiple EVs, or an electrical panel far from parked cars.
