1) On a regular basis using any device like yours in an area which would definitely benefit from GFCI protection at either the two receptacles used (e.g. a concrete floored basement garage that is prone to becoming damp when it rains)?
2) On a regular basis using any plug-in EVSE on a single non-GFCI protected receptacle in a similarly hazardous area?
Well, you can't use this device on GFI outlets. I would advise against removing GFI protection from outlets so that you can use this device.
I don't believe they sell GFI equipped 220 outlets. They do make GFI equipped ganged circuit breakers. You could use that to add GFI protection to this device. Remember that the GFI only protects in the downstream direction. It won't offer any proaction from malfunctions upstream. That's why building codes call for GFI outlets in bathrooms, kitchens and garages, where damp conditions are expected. The concern is plugging and unplugging the 120 cables of the "quick220" device itself when you're standing on a damp floor. There can be no GFI protection for that operation, because the device is incompatible with GFI outlets.
EVSEs are required by the J1772 specification to include their own GFI circuitry. So EVSEs are safe to use in all weather, HOWEVER, the GFI typically only protects from the J1772 cable to the car. You must follow the manufacturer's/builder's recommendation as to how to treat the chassis of the device and its electrical connection, as those are outside the scope of GFI protection. That said, standing on a wet floor and manipulating a 240 volt plug is not a great idea. If you had to do so you would be well advised to shut off the breaker and/or unplug the "quick220" device first.
