How to use

Connect the adapter to a mains outlet using the supplied AC lead or an appropriate regional power cord, then plug the output connector into the laptop's power inlet designed for 20V charging. Ensure the adapter's connector fits the device and that the device is rated for 20V input before connecting. When connected, the adapter will provide power for operation and battery charging; disconnect from mains and device when not in use.

Recommendations

Use this adapter with devices that explicitly support 20V DC input and the compatible connector. Match voltage and connector type before use, keep the adapter in a ventilated area during operation to avoid overheating, and disconnect it during thunderstorms or prolonged storage. For prolonged or heavy-duty usage, verify that the device's power draw does not exceed the adapter's 45W rating to prevent thermal throttling or insufficient charging.
