44 W AC adapter for Surface devices

A built-in USB 2.0 port adds 5 volt 1 amp charging for a phone or accessory at the same time. It ships with a six-foot AC cord and a compact wall plug for flexible placement.

15 V 2.58 A output specification

The adapter provides a fixed 15 volt 2.58 amp output rated at 44 watts, matching the original supply for the listed Surface families. Input accepts 100 to 240 volt AC for worldwide use. Built-in IC protection covers overload, short circuit and overheat conditions. UL certification is stated for the unit.

USB 2.0 port adds 5 V 1 A capacity

The extra port supplies up to 5 volts at 1 amp, enough for a smartphone or small accessory while the laptop charges. Total output remains limited to the 44 watt main rail, so heavy simultaneous loads may hit the protection limit. Users needing higher combined power or a different voltage rail should look elsewhere.
