Power Supply for Surface Devices

The Microsoft 1798 adapter delivers 102W of power to recharge Surface Book and Surface Pro batteries while you continue working. A built-in USB port lets you charge a second device such as a phone at the same time. The unit is designed to match the look and feel of your Surface hardware. It suits professionals who need reliable mains power for long sessions.

Magnetic SurfaceConnect Installation

The magnetized SurfaceConnect head snaps into the device port automatically, guiding alignment without force. An LED on the connector lights up once the connection is secure. The magnetic attachment disconnects safely if the cable is pulled, reducing strain on the port. No tools or driver installation are required; simply plug the adapter into a wall outlet and attach the connector.

Compatibility Check Before Ordering

Verify that your Surface model uses a SurfaceConnect charging port and supports 102W input. Confirm the adapter’s black finish matches your preference. Ensure you have a standard mains socket available for the power brick. This unit is not for users whose devices charge solely via USB-C or proprietary non-SurfaceConnect connectors.
