2. Safety Information
- Voltage Selection: Always verify the correct voltage requirement of your device before connecting the adapter. Setting an incorrect voltage can cause irreversible damage to your electronic device. Refer to your device's manual or specifications for its required input voltage.
- Polarity: Ensure the correct polarity is selected if your device requires it. This adapter typically uses center positive polarity (inner: positive, outer: negative) for its DC tips. Confirm your device's polarity before use.
- Current (Amperage): The adapter provides a maximum of 2000mA (2A). Do not use it with devices that require more than 2A, as this can damage both the adapter and your device.
- Indoor Use Only: This adapter is designed for indoor use. Do not expose it to rain, moisture, or extreme temperatures.
- Ventilation: Ensure adequate ventilation around the adapter during operation. Do not cover it or place it in enclosed spaces.
- Not for Laptops: This adapter is generally not suitable for powering laptops due to their higher power requirements.

5. Setup
- Determine Device Voltage and Amperage: Before connecting, identify the exact voltage (V) and amperage (A or mA) required by your electronic device. This information is usually found on the device itself, its original power adapter, or in its user manual.
- Select the Correct DC Plug Tip: Choose one of the 8 interchangeable DC plug tips that physically fits your device's power input port. Refer to the DC plug dimension and polarity diagram below.
- Set the Output Voltage: Using the included voltage adjustment key, rotate the red dial on the adapter to match the required voltage of your device (3V, 4.5V, 5V, 6V, 7.5V, 9V, or 12V). Ensure this step is performed accurately to prevent damage.
- Connect the DC Plug Tip: Firmly attach the selected DC plug tip to the adapter's output cable.
- Connect to Device: Insert the DC plug tip into your device's power input port.
- Plug into Power Outlet: Finally, plug the AC adapter into a standard wall power outlet (100-240V).

7. Maintenance
- Cleaning: Disconnect the adapter from the power outlet and your device before cleaning. Use a soft, dry cloth to wipe the surface. Do not use liquid cleaners or solvents.
- Storage: When not in use, store the adapter and its accessories in a cool, dry place, away from direct sunlight and moisture.
- Cable Care: Avoid bending or crimping the power cord excessively. Do not place heavy objects on the cord.
8. Troubleshooting
- No Power Output:
- Ensure the adapter is securely plugged into a working wall outlet.
- Verify that the voltage selection dial is set to the correct voltage for your device.
- Check that the DC plug tip is firmly connected to both the adapter cable and your device.
- Confirm that your device is compatible with the adapter's amperage (max 2A).
- Device Not Charging/Powering On:
- Double-check the voltage setting. An incorrect voltage can prevent operation or damage the device.
- Ensure the DC plug tip is the correct size and that its polarity matches your device's requirements.
- Test the adapter with another compatible device if possible to isolate the issue.
- Adapter Feels Warm During Use:
It is normal for the adapter to feel warm during operation, especially under load. If it becomes excessively hot or emits a burning smell, immediately unplug it from the wall outlet and discontinue use. Ensure proper ventilation around the adapter.
