6. Installation (Setup)
Before you begin: Ensure the power to the circuit is OFF at the circuit breaker or fuse box. Use a voltage tester to confirm no power is present.
- Turn Off Power: Locate the circuit breaker controlling the outlet you wish to replace and switch it to the OFF position.
- Remove Old Outlet: Unscrew and carefully pull the existing outlet from the wall box. Disconnect the wires from the old outlet, noting which wire was connected to which terminal (hot, neutral, ground).
- Prepare Wires: If necessary, strip approximately 1/2 inch of insulation from the ends of the wires.
- Connect Wires:
- Green or Bare Copper Wire (Ground): Connect to the green ground screw on the TOPGREENER outlet.
- White Wire (Neutral): Connect to the silver screw terminal.
- Black or Red Wire (Hot): Connect to the brass screw terminal.
This outlet supports both back-wiring (inserting wire into hole and tightening screw) and side-wiring (wrapping wire around screw and tightening). Note that USB outlets are typically deeper than standard outlets; ensure your electrical box has sufficient depth.
- Mount Outlet: Carefully push the wired outlet back into the wall box. Secure it with the provided mounting screws.
- Install Wall Plate: Attach the included wall plate over the outlet.
- Restore Power: Turn the power back ON at the circuit breaker.

7. Operation
The TOPGREENER USB Wall Outlet is designed for straightforward use.
- Using AC Outlets: Insert any standard 2-prong or 3-prong electrical plug into the tamper-resistant receptacles. A firm push may be required due to the safety shutters.
- Using USB Charging Ports: Connect your USB-A or USB-C compatible device directly to the corresponding USB port using a charging cable. The IntelliChip technology will automatically detect your device and deliver optimal charging current up to 2.4A per port, with a total shared output of 3.6A.
- You can charge up to two USB devices and power two AC devices simultaneously, provided the total load does not exceed the outlet's rating.

8. Maintenance
The TOPGREENER USB Wall Outlet requires minimal maintenance.
- Cleaning: Disconnect all devices and wipe the surface with a soft, dry cloth. Do not use liquid cleaners or sprays directly on the outlet.
- Regular Checks: Periodically inspect the outlet for any signs of damage, loose connections, or discoloration. If any issues are observed, turn off power at the breaker and consult a qualified electrician.
9. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No power from AC outlets or USB ports. | Circuit breaker tripped; loose wiring connection; faulty outlet. | Check and reset the circuit breaker. Ensure all wire connections are secure. If problem persists, consult an electrician. |
| USB device not charging or charging slowly. | Faulty USB cable; device not compatible; total USB load exceeds 3.6A; device requires fast charging (not supported). | Try a different USB cable. Ensure device is compatible with 5VDC charging. Reduce the number of devices charging simultaneously. Note that this outlet does not support fast charging technologies. |
| Difficulty inserting plugs into AC receptacles. | Tamper-resistant (TR) shutters require firm, even pressure. | Apply firm, even pressure to both prongs of the plug simultaneously. The shutters are a safety feature and require deliberate insertion. |
