Hello Dan and thank you for your question.
The GE Residential Electric Vehicle (EV) Level 2 WattStation (Model # EVWSWBC-CP01) has a NEMA-60 plug that is cord-connected to 40 amps. The station is hung onto the wall for regular use and can be moved to another location (for example when you move). This would be considered “portable” as compared to the hard-wired Level 2 WattStation.
Best wishes with your project.
