Compatible Surface power adapter

This 127W AC adapter replaces the original charger for Surface Book 3, Book 2, Laptop Studio, Laptop 3, Pro 8, Pro X, Pro 7, Pro 6, Pro 5, Pro 4, Pro 3, Go 3, Go 2 and Go 1. It accepts AC 100-240V input and delivers 15V 8A output. A built-in USB 2.0 port supplies 5V 1A for charging a phone or accessory at the same time.

Plug-in replacement with travel cord

The unit connects to the Surface proprietary connector and the wall outlet using the included 6.2 ft extra-long power cord. No drivers or configuration are required. The adapter intelligently regulates current to match 36W, 44W, 65W or 102W device requirements. Ensure the connector seats fully; a loose fit can interrupt charging.

Fixed 15V output and USB 2.0 limit

The barrel output is fixed at 15V 8A, so it cannot supply other voltages required by non-Surface devices. The USB port is limited to USB 2.0 at 5V 1A, which is slower than modern phone fast-charging standards. Buyers needing higher USB power or multi-voltage output should consider a separate USB-C PD charger.

Questions about this item

How can I confirm the 127W charger is delivering 15V 8A after setup?

The intelligent current regulation automatically matches 15V 8A for your Surface device; the connector LED lights when the correct voltage is present.

What comes in the box and what must I buy separately?

You receive the 127W power supply, an extra-long 6.2 ft power cord, a travel case and a manual; no extra cable is needed for the built-in USB 2.0 port.

Which output version should I choose for a Surface Pro 8 versus a Surface Go?

The single 15V 8A 127W output intelligently regulates down to 36W, 44W, 65W or 102W, so one unit covers both the Pro 8 and the Go models.
