How to use

Recommendations

Use this adapter with devices that support USB‑C power delivery and are compatible with a 45 W supply. Avoid using extension cords or adapters that may degrade performance, and keep the adapter ventilated during extended charging sessions. If the device draws less than 45 W, normal operation is expected; if the device requires more than 45 W, charging may be slower or device performance may be limited when under heavy load.
