110V "EVSE" (electric vehicle supply equipment) supplied by Nissan. This box is close to the outlet (the plug is just outside the frame, to the right). The SAE J1772 plug is about 8 metres to the left. Current draw is limited to 12 amps, so any 15 amp circuit will do, as long as you don't have anything else on the circuit. Charging is slow at 110V, but generally speaking there's still more than enough time to charge back up to 80% overnight. 80% is recommended for longest battery life.
(Why "EVSE" rather than charger? The "charger" is in the car, all the EVSE does is protect against faults and signal to the car how much current it is allowed to draw. It is a glorified extension cord, but one which works in all weather and is supposedly crushproof... shall we say, crush-resistant.)
