The Fusion Energi has a standard socket for charging the battery. Included with the Energi is a charger that fits into a standard 110v outlet. There are 220v chargers available for purchase, and this standard socket allows connection to chargers located throughout the country allowing you to stay charged. The beauty of the Fusion Energi is that you are not limited to finding chargers, when the battery runs out, you can continue on hybrid power and charge when you get back home. The range with fuel is over 600 miles!
