Battery status indicators
The adapter features LEDs that indicate the battery's charge level for 3 seconds after insertion and continuously during operation. The battery itself may also have its own charge indicator LEDs.
Maintenance and troubleshooting
Keep the battery and adapter clean and dry. If the USB device does not charge, check the battery charge, ensure the device is compatible, remove and re-insert the battery, or try a different cable.
