How to use

Confirm that your device accepts a 20V input and uses a 4.0×1.7 mm barrel connector before connecting the adapter. Plug the adapter into a suitable AC mains outlet, then insert the barrel connector into the device power inlet until it seats securely. Ensure the device is powered off when making the initial connection if recommended by the device manufacturer. After use, disconnect the adapter from the mains and the device by first unplugging from the mains to avoid arcing at the connector.

Usage recommendations

Use the adapter only with devices specified for 20V DC input and the matching connector size. Avoid exposing the adapter to moisture, extreme temperatures, or heavy physical impact. Inspect the connector and cable periodically for wear or damage, and replace the adapter if any defects are found. For optimal performance, allow adequate ventilation around the adapter during operation and store it in a dry place when not in use.
