Works well and has the ability to set the maximum charge amperage to 13,16, or 32 amps. To set hold the minus “-“ button until the amperage changes color then push plus or minus button until the amperage you’d like appears, then hold the minus button again. It also tells how many KW were put into the car as well as the charge time. Also shows the current amperage output while it’s charging. I used a Velcro strap hanger to hang it on the wall for use in my garage. I then wrap the chord around a hook off to the right while it’s not attached to the car.
