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.
