Power supply for Surface Pro 1, 2 and RT

This 48W AC adapter replaces the original charger for Microsoft Surface Pro 1, Pro 2 and Surface RT models. It delivers 12V at 3.6A from a 100-240V 50/60Hz input. A built-in USB 2.0 port supplies 5V 1A so a phone or other small device can charge at the same time. The unit ships with a 6ft mains cord and a storage pouch.

Installation is a simple plug-in

Connect the barrel tip to the Surface charging port and the IEC lead to a wall socket; no drivers or configuration are required. The only common issue is polarity or tip fit — verify the connector matches the device before forcing it. The USB port is standard 5V 1A output and will not fast-charge modern phones that expect higher current.

Steady output under continuous load

The adapter is rated for 48W continuous DC output, so it maintains 12V 3.6A while the laptop runs and charges the battery simultaneously. The additional USB 2.0 port draws up to 1A from the same 5V rail without reducing the main 12V supply. Thermal protection shuts the unit down if internal temperature exceeds safe limits during prolonged use.
