This 90W AC adapter is built as a direct replacement power supply for the Microsoft Surface Dock. It accepts 100-240V input for worldwide use and delivers 15V at 6.0A to the dock. A 5V 1A USB 2.0 port is included for charging a phone or small accessory simultaneously. The unit ships with a 6.2ft power cord and a storage pouch bag.

USB 2.0 Port Limit

The built-in USB port provides 5V at 1A, which is the standard USB 2.0 current limit. This output is suitable for topping up a smartphone or tablet while the dock is powered. It will not support higher-current charging protocols or fast-charge standards that require more than 1A. Plan on using the dock's own ports for any power-hungry peripherals.
