4. Setup and Installation
- Identify a Standard Duplex Outlet: Ensure the chosen wall outlet is a standard grounded duplex receptacle. This plug extender is not compatible with GFCI sockets or 2-prong sockets.
- Remove Existing Wall Plate (Optional): For a more secure and flush installation, you may remove the existing wall plate from your duplex outlet.
- Plug In the Extender: Insert the prongs of the Lvetek Outlet Extender into the top receptacle of the duplex outlet.
- Secure with Screw (Recommended): Use a screwdriver to fasten the included screw through the center hole of the extender into the outlet's screw hole. This provides added stability and prevents the unit from falling off, especially when multiple devices are plugged in.
- Verify Protection: Once plugged in, the "Protected" indicator light will illuminate, confirming that the surge protection is active.

5. Operating Instructions
Once installed, the Lvetek Multi-Functional Wall Outlet Extender is ready for use. Simply plug your devices into the available AC outlets or USB ports.
- AC Outlets: Plug in your standard electronic devices, appliances, and chargers. The 3-sided design allows for larger adapters without blocking other outlets.
- USB Charging Ports: Connect your smartphones, tablets, smartwatches, and other USB-powered devices. The smart technology will automatically detect and deliver the optimal charging current.
- Surge Protection: The built-in 1680 Joules surge protector continuously monitors the power supply to safeguard your connected devices from voltage fluctuations and power surges. The "Protected" indicator light will remain illuminated as long as the surge protection is active.


6. Maintenance
To ensure optimal performance and longevity of your Lvetek Multi-Functional Wall Outlet Extender, follow these simple maintenance guidelines:
- Keep Clean: Regularly wipe the exterior with a soft, dry cloth to remove dust and debris. Do not use liquid cleaners or abrasive materials.
- Avoid Overloading: Do not exceed the total power rating of 1875W. Overloading can cause damage to the unit and pose fire hazards.
- Inspect Periodically: Check the unit and connected cords for any signs of damage, fraying, or overheating. Discontinue use if any damage is observed.
- Surge Protection Indicator: If the "Protected" indicator light turns off, it means the surge protection components have absorbed a significant surge and may no longer be providing protection. It is recommended to replace the unit in such cases.
7. Troubleshooting
- No Power from Outlets/USB Ports:
- Ensure the extender is securely plugged into a functioning wall outlet.
- Check if the wall outlet itself is receiving power (test with another device).
- Verify that the total power consumption of connected devices does not exceed the 1875W Max. Power Rating.
- Check the "Protected" indicator light. If it's off, the surge protection may be compromised, and the unit needs replacement.
- USB-C Port Not Charging:
- The USB-C port is not Quick Charger 3.0 compatible. It does not support devices that require 9~22V charging voltage. Ensure your device is compatible with 5V/3A charging.
- Extender Not Fitting into Outlet:
- This plug extender is not compatible with GFCI sockets or 2-prong sockets. Ensure you are using a standard grounded duplex wall receptacle.
