3. Setup and Installation
The Addtam Surge Protector Outlet Extender is designed for simple plug-and-play installation into a standard duplex wall outlet. Follow these steps for proper setup:
- Identify a Suitable Outlet: Ensure the wall outlet is a standard 3-prong duplex outlet. The extender is compatible with standard and decor outlets. It is not recommended for USB receptacle or GFCI outlets unless the plastic post is removed (see Figure 3.3).
- Plug In: Align the prongs of the surge protector with the openings of the duplex wall outlet and push firmly until it is securely seated.
- Secure with Screw (Optional but Recommended): For enhanced stability, especially in high-traffic areas or with heavier plugs, use the provided screw to secure the extender to the center screw hole of the wall outlet plate. This prevents wobbling and accidental dislodgement.
- Verify Power: A small green indicator light on the front of the unit will illuminate, confirming that the surge protector is receiving power and the surge protection is active.

4. Operating Instructions
Once installed, the Addtam Surge Protector is ready for use:
- AC Outlets: Plug your electronic devices directly into any of the 6 AC outlets. Ensure that the total power draw of all connected devices does not exceed the maximum rating of the surge protector (1875W, 15A at 125V).
- USB Charging Ports: Connect your USB-powered devices (smartphones, tablets, smartwatches, etc.) to the USB-A or USB-C ports using appropriate charging cables. The smart charging technology will automatically detect your device and deliver the optimal charging current.
- Surge Protection Indicator: The green LED light indicates that the surge protection feature is active and functioning. If this light goes out, it means the surge protection has been compromised, and the unit should be replaced to ensure continued protection for your devices.
5. Safety Information
To ensure safe operation and prevent damage to your devices or the surge protector, please observe the following safety guidelines:
- Do not exceed the maximum electrical rating of 1875W (15A at 125V). Overloading can cause overheating and potential fire hazards.
- This device is for indoor use only. Do not expose to moisture or use in wet environments.
- Do not disassemble or modify the surge protector. Refer all servicing to qualified personnel.
- Keep children away from the surge protector and connected devices.
- Avoid plugging high-wattage appliances such as space heaters, microwaves, or hair dryers into the surge protector, as this may exceed its capacity.
- If the surge protection indicator light is off, the surge protection feature is no longer active. While the outlets may still provide power, your devices will not be protected from surges. Replace the unit immediately.
- Ensure the surge protector is firmly plugged into the wall outlet. A loose connection can generate heat and pose a fire risk.
6. Maintenance
The Addtam Surge Protector requires minimal maintenance:
- Cleaning: Disconnect the surge protector from the wall outlet before cleaning. Use a dry, soft cloth to wipe the exterior. Do not use liquid cleaners or aerosols.
- Inspection: Periodically inspect the unit for any signs of damage, such as cracks in the casing or discoloration. If damage is observed, discontinue use and replace the unit.
- Surge Protection Indicator: Regularly check the green LED indicator light. If it is off, the surge protection has been consumed, and the unit should be replaced.
