65W Surface Charger with USB Port

The 2-Power MU65W-A1706 is a 65W AC adapter built for Microsoft Surface Pro 3 through 12, Surface Laptop 1 through 7, Surface Book 1 and 2, Surface Go 1 through 4, Surface Laptop Go and Surface Laptop Studio. It delivers 15V at 4A through the magnetic connector and adds a 5V 1A USB port for charging a phone or tablet at the same time. The unit is new and carries ETL certification.

Replaces 44W 39W 36W and 24W Adapters

This charger replaces the 44W 15V 2.58A, 39W 15V 2.6A, 36W 12V 2.58A and 24W 15V 1.6A models listed under part numbers 1625, 1631, 1703, 1706, 1724, 1735, 1736, 1769, 1782, 1796, 1800, 1866, 1867 and 1873. The jump is worth it when your device supports 65W input because it charges a Surface Pro 8 in about one hour instead of the slower rate of the lower-wattage bricks. It is not for owners who need a 100W or higher supply for newer USB-C-only Surface hardware.

Magnetic Plug Snaps In Place

Installation is straightforward: align the magnetic tip with the charging port and let it snap into position; the indicator light confirms power flow. The corded design reaches the outlet without strain. The most common issue is debris on the magnetic contacts preventing a solid connection, so wipe both sides before plugging in. Another point to check is that the wall outlet supplies 100V to 240V at 50 or 60Hz, which matches the adapter’s input range.

Questions about this item

Does the 2-Power MU65W-A1706 charger use the magnetic connector that snaps onto Surface Pro 8 and Surface Laptop 5?

Yes, it has the high-sensitive magnetic connector used by Surface Pro 3 through Pro 12 and Surface Laptop 1 through 7, so it snaps into place on those models.

What is the first step when installing this charger, and what mistake should I avoid?

Plug the AC cord into a 100-240V 50/60Hz outlet, then attach the magnetic tip to the device; do not force the connector — it aligns magnetically and seats with a click.

When will the detachable AC power cord need replacing?

Replace the cord if the insulation frays, the plug pins bend, or the charger becomes intermittent; the brick itself is solid-state and has no user-serviceable parts.
