Q: How can I check whether my device supports PD protocol?

You can verify PD support by checking:

Device specifications-

Look for terms such as USB-C PD, Power Delivery, or PD 3.0/2.0 in the product description or manual.

Charger label-

If your original charger lists multiple voltage outputs (e.g., 5V/9V/15V/20V), it means the device supports PD negotiation.

Cable markings-

Certified PD cables often display “PD” or “E-Marker” labels and are rated for 60W or 100W.

Using PD-certified devices and cables ensures stable voltage regulation, heat protection, and optimal charging performance.
