65W Surface power adapter

This 65W AC adapter replaces the original charger for Microsoft Surface devices from the Pro 3 through Pro 9, plus Surface Laptop, Book, Go and Studio lines. It accepts 100–240V input for worldwide use and delivers 65W over the proprietary Surface connector.

Output limited to Surface connector

The brick supplies 12V or 15V DC at up to 65W through the magnetic Surface plug only. A single USB-A port adds 5V 1A for phone charging, but there is no USB-C PD output, so newer laptops that require Type-C charging cannot be powered.

Replaces lost or damaged 36W 44W units

Buyers with a failed 36W or 44W adapter gain headroom for faster charging and simultaneous USB-A use. The step up is not worthwhile for users who only need the lower wattage or who require USB-C Power Delivery for non-Surface hardware.

Questions about this item

Which power rating matches my Surface model — 36W, 44W or 65W?

The 36W variant delivers 12V at 2.58A and fits Surface Pro 3, 4, i5/i7, Surface Laptop and Surface Go 1-3. The 44W variant delivers 15V at 2.58A for the same models. The 65W variant delivers up to 65W and also covers Surface Book 1-3, Surface Laptop 1-5, Surface Laptop Studio, Surface Laptop Go, Surface Pro 3-9, X, 7+ and Surface Go 1-3.

What does the 65W rating actually provide when the adapter is plugged into my laptop?

At 65W the adapter can supply 15V at up to 4A through the Surface Connect port while simultaneously offering 5V at 1A from the USB-A port, so the laptop charges at full speed and a phone or accessory can draw 5W at the same time.

What connector standard does this charger use and what does it limit in practice?

It uses Microsoft's proprietary Surface Connect interface, which carries both power and data; the 65W brick is limited to 15V 4A on that port and 5V 1A on the USB-A port, so it cannot exceed 65W total output.
