Compatible dock power supply

This 90W 15V 6A AC adapter replaces the original charger for Microsoft Surface Pro 4 5 6 Docking Station models 1661 and 1749, plus Surface Book Docking Station units PD9-00003 PD9-00011 PF3-00012 PF3-00007. It delivers the exact voltage and current those docks require. Builders using non-Surface docks or laptops that need a different voltage cannot use this unit.

Build integration

The adapter accepts 110-240V input so it works worldwide without a separate transformer. A detachable mains cord is included in the package, leaving only the low-voltage cable to route behind the desk. No extra mounting hardware or proprietary connectors are needed beyond what the dock already provides. Buyers who need a second simultaneous power source for another device will need a separate adapter.

Sustained load behaviour

UL FCC and RoHS certifications cover the built-in overcharge short-circuit overload and over-heat protections that keep output stable during long charging sessions. The 12-month warranty period reflects the manufacturer’s confidence in continuous reliability. Users who run the dock at maximum peripheral load for extended periods should still ensure adequate ventilation around the adapter body.

Questions about this item

What is the maximum continuous power the BFKK 1661 can deliver to a Surface Dock?

How much heat or fan noise does the 90W charger produce during all-day use?

The unit has no fan and relies on passive cooling; it will become warm during continuous operation but runs silently.
