Roger, I've had no problems charging outside in the rain and sleet and snow for over 4 years now. Careful installation matters as much as having a weatherproof EVSE. One local EVSE failed recently because condensation inside the wiring conduit flowed down through the long run into the EVSE, gradually filling it up with water, though corrosion was what finally caused the failure. Make sure that liquid cannot flow through conduit into your EVSE box by routing the conduit from below, or from the side plus a junction box with weep holes, etc. etc..
