15 V 6 A 90 W AC Adapter for Surface Dock

This 90 W power supply delivers 15 V at 6 A for Microsoft Surface Dock model 1749 and the Surface Pro 4 docking station. It also supports Surface Book 2, Surface Pro (2017) and Surface Pro 3 devices. The unit ships with a charger cord and instruction book.

Check dock model and input voltage

Verify that your docking station is the Surface Dock model 1749 or the Surface Pro 4 dock, because the adapter is not compatible with the Surface Pro 3 dock station. Ensure your mains supply falls within the 100-240 V 50/60 Hz range before connecting.

Replaces lost or faulty 90 W dock chargers

This adapter replaces the original 90 W supply that shipped with the Surface Dock 1749 or Surface Pro 4 dock. The upgrade is worth it when the original charger is lost, damaged or no longer holds a stable 15 V output. Buyers needing a higher wattage unit or a USB-C power delivery adapter will not be served by this model.
