SMUGDESK USB C to DC 1215V PD 65W Charging Cable for Surface Pro 3 4 5 6 Book

Charging cable for Surface Pro and Book

This USB‑C to DC cable converts Power Delivery input into a stable 1215V DC output for Microsoft Surface Pro 3, Pro 4, Pro 5, Pro 6 and Surface Book. It supports up to 65W charging so you can power the tablet or laptop from a compatible USB‑C PD adapter without the original charger. No drivers are required; the cable works immediately when connected. It is designed as a compact travel and backup charging solution.

Check your USB‑C power source before ordering

The cable only functions when paired with a USB‑C charger that supplies Power Delivery at the required voltage and wattage. Verify that your adapter explicitly lists PD 65W output; a standard USB‑C port without PD will not deliver power. Confirm the DC connector matches the proprietary port on your specific Surface model. This cable cannot charge devices that use a different voltage or connector type.

Thermals noise and power draw

The cable itself contains no active cooling, fans or semiconductors, so it generates no audible noise during operation. Power draw is determined entirely by the attached PD charger and the Surface device’s charging circuit, with the cable passing up to 65W. In normal use the cable remains at ambient temperature and adds no measurable heat to the setup. It is a passive conduit that does not alter the thermal profile of the charger or the Surface.
