65W AC adapter for Microsoft Surface

This 65W power adapter is built for Microsoft Surface Pro, Laptop, Book, Go and Studio devices. It matches models 1706, 1724, 1735, 1796, 1800, 1866 and 1867, and supports Surface Pro 11, 10, 9, 8, 7+ and earlier. Buyers needing a charger for non-Surface laptops cannot use this unit.

Capacity and headroom

The 65W output fully charges a Surface Pro in 1.5 hours, which is faster than standard 44W, 39W, 36W and 24W chargers. It delivers enough headroom for simultaneous use and charging on supported devices. Systems that require more than 65W will not reach full performance with this adapter.

Thermals, noise and power draw

Built-in safeguards protect against overcharging, overheating and short-circuiting to maintain safe operating temperatures. The 7.8FT cable allows flexible placement without strain on the connector. The brick runs silently with no moving parts during normal operation.
