When using an adapter, the following precautions should be taken:

1. Voltage matching: Ensure that the input voltage of the adapter matches the local power grid voltage to prevent equipment damage or safety accidents caused by voltage mismatch.

2. Correct connection: Connect the adapter plug tightly to the power interface of the device and ensure that the other end is firmly inserted into the power socket to prevent loosening or detachment.

3. Avoid overload: Make sure that the power of the device does not exceed the rated power of the adapter to prevent overheating or damage to the device.

4. Avoid overvoltage and overcurrent: Regularly check the working status of the adapter to ensure that the voltage and current are within a reasonable range to ensure the normal operation of the equipment.

5. Moderate rest: Prolonged use of the adapter may cause overheating. It is recommended to rest appropriately and regularly unplug the adapter.

6. Usage environment: Avoid exposing the adapter to high temperature, humidity, or direct sunlight to avoid affecting its service life.

7. Waterproof and moisture-proof: As an electronic product, the adapter may cause corrosion or oxidation of internal electronic components due to water ingress or prolonged exposure to humid air, so it needs to be waterproof and moisture-proof.

8. Anti drop and shock-absorbing: The internal components of the adapter are fragile, so avoid falling, knocking, or vibration to prevent damage to the internal circuit board.

9. Cleaning and maintenance: Regularly clean the adapter, but be careful to use a damp or anti-static cloth and avoid using dry cloth to prevent static damage.

10. Safe storage: When not in use, promptly unplug the adapter from the socket and store it properly to avoid external pressure or damage.

Following the above precautions can ensure the safe and effective use of the adapter, and extend its service life.
