36 W AC adapter for Surface Pro 3 and 4

This 36 W power supply replaces the original charger for Microsoft Surface Pro 3 and Surface Pro 4 i5 or i7 tablets. It delivers 12 V at 2.58 A through a 4.5 × 3.0 mm connector. The unit accepts 100–240 V worldwide input and includes a 6.2 ft AC cord plus a 5 ft DC cord for flexible placement.

Capacity and headroom

At 36 W the adapter runs the tablet and charges the battery under normal workloads such as office apps, web browsing and video playback. Heavier sustained loads that draw more current than 2.58 A will exceed the brick’s rating and may cause the connector to limit power or shut down. The built-in IC chip protects against over-current, overheating and overcharging during regular use.

USB charging port

A 5 V 1 A USB port is integrated into the adapter body so you can charge a phone or small accessory from the same outlet. The extra port shares the same 48 W total budget, so simultaneous high-draw charging on both outputs will reduce available power for the Surface. Buyers who need more than 1 A on the USB side should look elsewhere.
