Troubleshooting
If you encounter issues with your TESSAN power strip, please refer to the following common problems and solutions:
- No Power to Devices:
- Ensure the power strip's plug is fully inserted into the wall outlet.
- Check if the wall outlet itself is functioning by plugging in another device directly.
- Verify that the total power consumption of connected devices does not exceed 1250W. Overloading can trigger internal safety mechanisms.
- Slow USB Charging:
- Ensure your device's charging cable is not damaged and is compatible with the USB port (USB-C or USB-A).
- Some devices may charge slower if multiple high-power devices are connected simultaneously to the AC outlets or other USB ports.
- Check your device's charging requirements; the USB-C port provides up to 15W, and USB-A ports provide up to 12W.
- Surge Protection Indicator (if applicable): If the surge protection indicator light (if present) is off, it may indicate that the surge protection has been compromised after a significant power surge. In this case, the power strip may still function as an extension cord, but its surge protection capability is no longer active. Consider replacing the unit.
