4. Setup: Charging Your Smartwatch
4.1 Connecting the Charger
- Ensure your smartwatch is clean and dry around the charging contacts.
- Align the magnetic charging pins of the cable with the charging contacts on the back of your smartwatch. The magnets will automatically snap into place.
- Verify that the magnetic attraction is strong and the connection is secure. If the magnets repel, the device will not charge.

Once the charging cable is securely connected to your smartwatch, plug the USB-A end of the cable into a compatible power source:
- USB Wall Charger: Use a standard USB wall adapter (recommended 5V/1A output).
- Computer/Laptop USB Port: Connect to an available USB port on your computer or laptop.
- Power Bank: Use a portable power bank for on-the-go charging.


5. Operating
The Lamshaw Smart Watch Charger operates automatically once connected to a power source and your compatible smartwatch. The smartwatch display will typically indicate that it is charging (e.g., a battery icon with a lightning bolt or a charging percentage). Disconnect the charger once your smartwatch is fully charged.

6. Maintenance and Care
- Cleaning: Gently wipe the charging contacts on both the cable and your smartwatch with a dry, soft cloth to remove any dust or debris. Do not use liquid cleaners.
- Storage: When not in use, store the cable in a cool, dry place, away from direct sunlight and extreme temperatures. The flexible PVC cable is designed for easy rolling and convenient storage.
- Handling: Avoid bending the cable sharply or pulling it by the cord. Always grasp the plug when disconnecting from a power source or your smartwatch.
- Water Exposure: This charger is not waterproof. Avoid exposing it to water or other liquids.
