How to use

Connect the USB‑C cable from the adapter to the USB‑C power input on the laptop or device. Ensure the device supports USB Power Delivery and that its power requirement does not exceed 90W. Plug the adapter into an AC mains outlet and check the device’s charging indicator to confirm power delivery. If the laptop requires a specific power negotiation, allow a few seconds for the device and adapter to establish the correct delivery profile before intensive use.

Recommendations

Use the adapter with compatible Dell and other USB‑C devices that accept power delivery. Avoid using the adapter in wet or excessively dusty environments, and store the adapter in a cool, dry place when not in use. If charging performance appears reduced, inspect cables and connectors for damage and ensure the laptop firmware supports USB‑C power negotiation.
