Simple Plug-In Power

The adapter connects directly to the device’s proprietary charging port with no extra cables or docks required. Its 100V-240V input handles international mains voltages automatically. A single brick replaces several older Microsoft charger models including the 1625, 1735, 1736, and 1800 series. The compact form factor keeps desk clutter low.

Questions about this item

Will the 12V 2580mA output sustain continuous load without voltage drop?

The adapter delivers a regulated 12V at up to 2.58A (36W) from a 100-240V 50/60Hz input, matching the original Surface Pro 3/4 power requirement.

How much heat or fan noise does the brick produce when left plugged in all day?

The unit is a sealed passive supply with no fan; it warms slightly under full 36W load but stays within normal operating temperature for a compact AC adapter.

Which Surface connector does the cable terminate in so I know it fits my device?

The cord ends in the proprietary Microsoft Surface magnetic connector used on Pro 3, Pro 4, Pro 5 (2017), Surface Book, Surface Book 2 and Surface Laptop (2017).
