Microsoft Surface 102W Charger — Superior 15V Surface

The Microsoft Surface 102W Charger is a high-output Surface Connect power adapter built around Microsoft Power Supply Model 1798. Microsoft specifies Model 1798 at 15V and 6.33A, providing approximately 95W directly to compatible Surface devices. It is designed for higher-powered Surface Book and Surface Laptop Studio configurations that need considerably more power than standard 44W or 65W Surface adapters.

Which Surface Devices Need Model 1798?

Microsoft specifically assigns Model 1798 to several higher-performance Surface configurations. Surface Book 2 models with discrete NVIDIA graphics are among the main systems associated with this charger, including the 15-inch Surface Book 2 and 13.5-inch version with NVIDIA GPU.

Verified configurations include:

• Surface Book 2 15-inch
• Surface Book 2 13.5-inch with NVIDIA GPU
• Surface Book with Performance Base
• Surface Book 3 13.5-inch with NVIDIA discrete GPU
• Surface Laptop Studio with NVIDIA discrete GPU
• Surface Laptop Studio 2 configurations requiring 95W

Why Is a 102W Charger Listed as 95W by Microsoft?

The Surface Connect output itself supplies approximately 95W, calculated from the documented 15V × 6.33A output. Model 1798 also includes a separate USB-A charging output rated at 5V / 1.5A, giving additional power for another device and producing the charger's commonly used 102W total rating.

That gives the adapter the following power profile:

• 15V DC Surface output
• 6.33A Surface output current
• Approximately 95W to the Surface device
• 5V / 1.5A auxiliary USB-A output
• 102W combined power class

Higher Wattage Matters on Performance Surface Models

Performance-focused Surface Book configurations combine a processor, high-resolution display and discrete graphics hardware. Microsoft therefore specifies a 95W minimum power requirement for Surface Book 2 systems with NVIDIA graphics rather than the lower 39W or 60W adapters used by less demanding configurations.

Using the correctly rated charger gives the system the power profile Microsoft specifies for charging and operation under heavier workloads.

Check Model 1798 Before You Order

Surface Connect plugs can appear identical across several Microsoft charger wattages. For this adapter, the strongest identifiers are Model 1798, 15V and 6.33A. Matching these details with the label on your existing charger helps prevent confusion with 44W, 65W or 120W Surface power supplies.
