Operating Instructions
Once the adapter is connected to both the device and a power outlet, it will begin to supply power or charge the device's battery. The adapter provides a stable 5V DC output.

- Charging Time: Charging time will vary depending on the battery's current charge level and capacity.
- Battery Life: Rechargeable batteries have a finite lifespan, typically 1 to 3 years. An old or degraded battery may not accept a charge, which is not an indication of a faulty charger.

- Keep Dry: Avoid exposing the adapter to water or excessive moisture.

- Cable Care: Do not bend, twist, or pull the power cord excessively. Avoid placing heavy objects on the cord.
The adapter is equipped with safety features including:
- OVP (Over Voltage Output Protection): Protects against excessive output voltage.
- OCP (Over Current Output Protection): Protects against excessive output current.
- SCP (Short Circuit Output Protection): Protects against short circuits.
Troubleshooting
If you encounter issues with your adapter, consider the following:
- No Power/Charging:
- Ensure the adapter is securely plugged into both the wall outlet and the device.
- Verify that the wall outlet is functional by testing it with another device.
- Check the adapter cable for any visible damage.
