65W Surface Charger with USB

The 2-Power MU65W-A1706 delivers 65W at 15V 4A through a magnetic connector compatible with Surface Pro 3 through 11, Surface Laptop 1 through 7, Surface Book 1 through 3, Surface Go 1 through 4, Surface Laptop Go 1 through 3 and Surface Laptop Studio models. A built-in USB-A port supplies 5W at 5V 1A for charging a phone or tablet simultaneously. The unit accepts 100-240V AC input at 1.3A.

Magnetic connector and extra port

The magnetic plug attaches securely to the device charging port and includes a power status indicator visible on the computer when charging completes. The integrated USB-A output frees a separate wall adapter for a mobile device, reducing the number of cables needed on a desk or in a travel bag. Overload, short-circuit and thermal protection circuits are built into the adapter.

Replaces lower-wattage Surface adapters

This 65W unit replaces original Microsoft chargers rated at 65W, 44W, 39W, 36W and 24W, providing faster charging for compatible models that support the higher input. It is not suited for devices that require a different voltage or connector type, nor for users who need more than one additional USB charging port.

Questions about this item

Will the 65W 15V 4A output sustain a Surface Book 3 under continuous load without throttling?

The adapter delivers 65W at 15V 4A, matching the highest factory Surface charger rating, so it can maintain full power during sustained workloads on compatible models including Surface Book 3.

Does the magnetic connector or the brick get hot or noisy when charging a Surface Laptop 7 all day?

The unit uses a corded electric design with integrated overload, short-circuit and thermal protection chips; no fan is present, so operation is silent and heat stays within normal limits for a 65W supply.

What cable or plug must I already have to use the USB charge port on this charger?

The USB-A port supplies 5W at 5V 1A; you only need a standard USB-A to Lightning, USB-C or Micro-USB cable for your phone or tablet — no extra proprietary cable is required.
