Magnetic 65 W charger for Surface

This 65 W magnetic AC adapter is built for Microsoft Surface Pro, Surface Laptop, Surface Book and Surface Go models listed in the compatibility table. It delivers 15 V at 4 A through a magnetic connector that snaps into place. Travellers and mobile professionals who need a compact replacement for the original power supply will find it fits the same devices.

Thermals noise and power draw

The unit accepts 100–240 V input at 50–60 Hz for worldwide use and outputs up to 65 W, also covering 44 W, 39 W, 36 W and 24 W devices. An internal chip adjusts power based on device temperature and battery status, reducing heat during charging. Flame-retardant materials and built-in safeguards protect against overcurrent, short-circuit and overheating. No fan is present, so operation is silent.

Bundled cable and protection

The package includes the power adapter and a detachable power cord, so the unit is ready to use out of the box. Short-circuit protection and the temperature-aware charging logic work together to extend battery lifespan and improve safety. The magnetic jack prevents accidental strain on the port. Buyers needing more than 65 W for larger laptops should look elsewhere.

Questions about this item

How do I attach the magnetic connector and which way round does it go?

The magnetic tip snaps onto the Surface charging port in either orientation; no alignment notch is required.

What part will wear out first and need replacing?

The detachable AC cord is the only user-replaceable item; the adapter body has no serviceable components.

At what sustained load does the adapter hit its thermal limit?

Continuous draw above 65 W triggers the over-temperature protection and the unit will throttle or shut down.
