14-50 plug. This is the smallest 32 amp portable EVSE on the market. Charge at up to 5 times a standard 110 charger or over 7 kilowatt! Will charge any electric vehicle or PHEV with a J1772 receptacle. There is a button on the front to select between 16 and 32 amp charging. Smart LCD Screen Displays: K/W, Amperage, Voltage and, Time Charged. The length is 22+ feet. This is my personal favorite of all the evse I've tried and is what I currently use to charge my electric vehicle at its full potential.
