Toyota includes an adapter cable that plugs into any 110-volt outlet. The end of the cable that plugs into the car uses the standard J1772 electric car charging port. If you use a 110-volt outlet, the car will charge up in 3 hours. From a 220-volt outlet, the battery charges in just 1.5 hours. The Prius Plug-in can also be plugged into a level 2 charger, which should take only minutes to fill the battery pack.
