The United States uses mains electricity supplied at 120 volts at 60 Hz. Wall outlets use Type A and Type B plugs.

Plug types are listed because they are encountered in at least some installations. Presence may be partial, legacy, mixed, or situational. A travel adapter, also spelled travel adaptor, changes plug fit only; a voltage converter, sometimes searched as a voltage convertor, is needed only for devices that are not dual voltage. No plug type is excluded due to limited or declining use.
