The level 1 NEMA 5-15 EV charger is the standard EV charger provided by most car manufacturers when you buy your car. It is a standard 3 pin connector used in the home (i-phone, toaster, laptop etc). For safety reasons we provide a 12 AMP charge for level 1 NEMA 5-15 EV charges so as not to overload the circuit and trip the breaker. Other companies provide 16 AMP chargers which results in frustration with the breaker tripping since you should only pull 80% of the breaker rating. This level 1 NEMA 5-15 EV charger is for Level 1 charging, allowing you the convenience and flexibility of moving from one location to another wherever you are in the U.S. The level 1 NEMA 5-15 EV chargers come in two different lengths 25ft and 32ft.
