Should I buy a hardwired or plug-in (NEMA 14-50) home EV charger?

Plug-in units are easier to install, relocate, and replace, and they can be moved with you. Hardwired units are generally required for continuous 48A/11.5kW operation and tend to be favored for permanent outdoor installs. Several candidates here come in both versions (for example EVIQO offers a 48A hardwired and a 40A plug-in), so match the choice to your panel capacity and whether you want portability.
