The Type1 to type2 EV Charging Cable Adapter. It is a versatile electric car charger connector designed to convert your type 1 home charger cable fitting, to fit your type2 car without having to change the type1 cable on your charger, meaning you can charge EV's with typ 1 or type2 quickly and easily, changing to suit. It is of a sturdy construction and a compact design. I have used this for several years with no issues.
