Power Supply for Surface Dock 2

This 199W AC adapter delivers 15.35V at 12.96A to power a Microsoft Surface Docking Station 2, model 1931 or 1917. It accepts a worldwide 100-240V input at 50/60Hz and 3.5A, making it suitable for office desks or travel bags. The package includes the adapter and a US power cord.

Replacement for Lost or Failed Dock Chargers

It replaces the original supply that shipped with the Surface Dock 2 when that unit is lost, damaged or no longer holds voltage. The jump is worth it when the dock fails to negotiate full power with connected laptops or peripherals, restoring the rated 199W throughput. Buyers who need a higher wattage brick for other devices cannot use this fixed-voltage adapter.

Sustained Output Under Continuous Load

The adapter maintains its 15.35V rail during extended sessions driving multiple displays, Ethernet and USB accessories from the dock. Thermal design keeps output stable without throttling when the dock draws near the 199W limit for hours. No fan noise is generated because the unit relies on passive convection cooling.

Questions about this item

What power input range does the 199W adapter require?

The adapter accepts 100-240V at 3.5A, 50/60Hz, so it works on mains supplies worldwide without a voltage converter.

Which connector does the 1931 model use to attach to the Surface Dock 2?

It uses the proprietary Surface Connect plug that mates directly with the dock's power input; align the magnetic connector and press until it seats.

When should the US power cord supplied with the 199W unit be replaced?

Replace the cord if the plug pins are bent, the insulation is cracked, or the cord becomes warm during normal 199W operation.
