The practical answer
Hardwired is often the more reliable long-term home setup because it removes the outlet and plug as heat/failure points and can support higher amperage. A NEMA 14-50 outlet is useful when portability or renting matters, but the outlet must be high quality and installed for continuous EV loads.
Decision path
- Choose hardwired for permanent outdoor or high-output installs.
- Use plug-in only with a high-quality receptacle installed for continuous EV charging.
- Do not treat a cheap dryer-style outlet as equivalent to EV charging hardware.
- Watch for GFCI nuisance trips where local code requires a GFCI breaker on a 240V outlet.
