- Press the main power button on the top of the unit to ensure it is in the "ON" position. The blue indicator light should be illuminated.
- Check your home's circuit breaker panel to ensure the wall outlet circuit has not tripped.
- If the power bar was overloaded, its internal circuit breaker might have tripped. Unplug some devices, then press the power button to reset.
- USB Ports Not Charging Devices:
- Verify that the USB cables are properly connected to both the power bar and your device.
- Try using a different USB cable or a different USB port on the power bar.
- Ensure your device is compatible with the USB charging specifications (5V/3.0A Max for USB-C, 5V/2.4A Max for USB-A, 17W Total). Some devices may require higher power delivery.
- Surge Protection Indicator Light is Off:
