65W AC adapter for Microsoft Surface

The 2-Power 1706 is a 65 watt AC adapter built for Microsoft Surface devices including Surface Pro 3 through 11, Surface Laptop 1 through 7, Surface Book 1 through 3 and Surface Go 1 through 3. It delivers 15 volts at 4 amps through a magnetic Surface connector and adds a USB 2.0 port rated at 5 watts for charging a phone or accessory. The unit accepts universal 110 to 240 volt input at 50 or 60 hertz.

Check connector and power needs

Verify that your Surface model uses the magnetic Surface charging tip listed in the compatible part numbers such as 1706, 1736, 1769, 1796, 1800, 1824, 1866, 1867, 1873, 1943, 1625, 1631, 1703, 1724, 1735 or 1782. Confirm the device requires 15 volt input at up to 4 amps; the adapter also supports 44 watt and 39 watt profiles but will not suit units needing 20 volt or higher current delivery. Ensure you have a standard IEC C7 or C5 mains lead for the AC inlet.

Replaces lost or worn Surface chargers

This adapter replaces an original Microsoft 65 watt, 44 watt or 39 watt supply when the original is lost, damaged or the cable has frayed. The jump is worthwhile if you need the extra USB 2.0 port for simultaneous charging or if the magnetic tip on your old unit no longer holds securely. It is not for devices that require 20 volt 3.42 amp 85 watt input or proprietary non-magnetic connectors.

Questions about this item

What comes in the box and do I need to buy a mains lead separately?

The adapter ships with a fixed mains cable and a magnetic Surface connector, plus a built-in USB 2.0 port for charging a phone; no extra cord is required.

Should I choose the 65 W version or the 44 W version for my Surface Book 3?

The 65 W unit (15 V 4 A) covers every model listed including Surface Book 3, while the 44 W (15 V 2.58 A) only suits lower-power devices.

What does the 65 W rating actually deliver when the laptop is under load?

It supplies a steady 15 V at up to 4 A to the Surface, and the extra USB 2.0 port can simultaneously provide 5 W for a phone or accessory.
