Compatible Surface power adapter

This 102W adapter replaces the original charger for Microsoft Surface Book 2 13-inch and 15-inch models. It also supports Surface Book 3, Surface Laptop 1 through 5, Surface Pro 3 through 9 and X, Surface Go 1 through 4, Surface Laptop Go and Surface Laptop Studio. The magnetic connector plugs in without precise alignment and a blue LED confirms charging status.

Upgrades from lower-wattage units

Swapping a 65W or 96W supply for this 102W unit removes the power ceiling that can throttle sustained loads or slow charging while the laptop runs demanding workloads. The jump is worth it when the original adapter cannot keep the battery full during video editing, compile jobs or long meetings. A 15V 6.33A output matches the highest factory specification across the compatible range.

Build integration and extras

The brick accepts 100-240V AC input at 50-60Hz for worldwide use without a voltage converter. A built-in USB 2.0 port delivers 5V 1.5A so a phone or tablet charges alongside the laptop, reducing the number of wall outlets needed. Protection circuits cover over-current, short-circuit, over-voltage, over-temperature, fire and grounding faults. The package includes only the adapter and detachable AC cable.

Questions about this item

What connector does the 1703 adapter use to attach to the Surface device?

It uses a magnetic plug that snaps onto the Surface charging port; the blue LED on the plug lights to confirm the connection.

How do you set up the charger for the first time, and what step is often missed?

Plug the AC cord into a 100–240 V outlet, then attach the magnetic tip to the Surface; the often-missed step is waiting for the blue LED to glow before assuming charging has started.

Which parts of this 102 W adapter may need replacement after extended use?

The detachable AC cord and the magnetic DC cable are the items most likely to wear out; the USB 2.0 port (5 V 1.5 A) remains usable for phone charging.
