Receptacles with USB combine standard electrical outlets with built-in USB ports, allowing users to power plug-in equipment while charging compatible devices from the same wall location. Dual USB ports support convenient charging without occupying the standard receptacle connections needed for lamps, appliances, and other equipment.

Receptacles with USB support side- or back-wire connections, and the listed 15-amp models accept up to two 14 AWG or 10 AWG wires per terminal. For dual-dimmable 20-amp models, use standard switched-receptacle wiring with two separate live or hot feeds, and follow the installation instructions because the top and bottom outlets may have specific connection and dimming requirements.

Tamper-resistant receptacles with USB combine standard power outlets with built-in USB ports for charging compatible devices without a separate adapter. They also use a spring-loaded slider that helps block insertion of single-pronged objects while still allowing electrical plugs to connect.

Some receptacles with USB can work with compatible dimming controls, including versions that allow both outlets to dim together or independently, while standard USB receptacles may be intended for coordination with compatible switches or dimmers rather than direct dimming. Before installation, verify the receptacle type, control compatibility, voltage and amperage, wiring configuration, need for separate hot feeds, and whether the receptacle accepts standard plugs.
