1. Introduction
The TESSAN Power Strip Tower (Model TPS04-JP) is a compact and versatile power solution designed for various environments. It features 8 AC outlets, 1 USB-C port, and 2 USB-A ports, allowing simultaneous charging of multiple devices. The wide spacing between AC outlets accommodates large adapters without blocking adjacent ports. Its 1-meter extension cord and 45-degree thin plug facilitate easy cable management in tight spaces, preventing electrical fire hazards with an insulated plug base. Equipped with a master switch for convenient power control and overload protection, it automatically shuts off power in case of overload or overcurrent. Integrated 1700J surge protection safeguards connected electronics from lightning damage, indicated by a red lamp when active. Its low center of gravity and non-slip feet ensure stability.

4. Maintenance
To ensure optimal performance and longevity of your TESSAN Power Strip Tower, follow these maintenance guidelines:
- Cleaning: Disconnect the power strip from the wall outlet before cleaning. Use a dry, soft cloth to wipe the exterior. Do not use liquid cleaners or abrasive materials.
- Storage: When not in use for extended periods, store the power strip in a cool, dry place away from direct sunlight and moisture.
- Inspection: Periodically check the power cord and plug for any signs of damage, such as fraying or exposed wires. If damage is found, discontinue use immediately and contact customer support.
5. Troubleshooting
5.1 No Power to Devices
- Check Master Switch: Ensure the master switch on the power strip is in the ON position (green indicator light should be illuminated).
- Check Wall Outlet: Verify that the wall outlet is functioning correctly by plugging in another device.
- Overload Protection: If the power strip automatically turned off, it might be due to an overload. Disconnect some devices, then press the master switch to reset the power strip.
5.2 Surge Protection Indicator (Red Lamp)
- Red Lamp On: A red lamp indicates that the surge protection feature is active and functioning normally. This means the power strip is protecting your devices from voltage spikes.
- Red Lamp Off: If the red lamp is off, it may indicate that the surge protection component has been compromised or has reached its end of life after absorbing a significant surge. While the power strip may still function as a multi-outlet, its surge protection capability might be reduced or non-existent. Consider replacing the unit for continued surge protection.
