NOCO GENIUS-BOOST+-GB40 user manual

The Noco Boost Plus GB40 has four indicator lights:
1. Power: This light indicates the battery's voltage level and power status. It turns on when the Boost Plus is connected to the battery or a power source.
2. Error: If this light is solid red, it indicates a reverse polarity error. When blinking red, it denotes a battery error or low voltage.
3. GB40: This light shows the level of charge in the Boost Plus. It starts blinking when the unit is charging and turns solid green when it is fully charged.
4. USB: This light illuminates when the USB port is active and ready to charge devices.
These indicator lights provide information about the Boost Plus's status and alert you to any potential issues.

A blinking white light on your Noco boost could indicate a few different things, depending on the specific model you have. Here are a few possible reasons:
1. Charging in progress: Some Noco boost models have a blinking white light to indicate that the device is currently charging. This is a normal operation and suggests that the unit is receiving power.
2. Faulty connection: If the blinking white light persists even after ensuring a proper connection to the power source, it might indicate a faulty or loose connection. Double-check the connections between the boost and the power source, making sure they are secure and properly plugged in.
3. Error or warning code: Certain Noco boost models use different colored lights to indicate specific error or warning codes. Refer to the user manual for your specific model to determine if a blinking white light is an error or warning code. In this case, the user manual should provide information on what the code means and how to troubleshoot it.
If you are unable to determine the cause of the blinking white light or if the light continues to blink even after trying the suggested fixes, it is recommended to contact Noco customer support for further assistance.
