What it is and who it's for

The 2-Power MU65W-A1706 is a 65W AC adapter built for Microsoft Surface Pro, Laptop, Go, Studio and Book models from 2017 onward. It delivers 15V at 4A through the proprietary magnetic connector and includes a USB-A port rated at 5V 1A for charging a phone simultaneously. The package supplies the DC cable, an AC cord, a mini wall plug and a travel case. Buyers who need a higher-wattage brick for power-hungry workstations or a USB-C Power Delivery output will not find those features here.

Behaviour under sustained load

The adapter is UL certified and specifies protections against over-current, short-circuit, over-voltage and over-temperature. Output can also step down to 44W, 36W or 24W depending on the connected device, allowing the unit to run within its thermal limits during extended charging sessions. Input voltage ranges from 100 to 240V at 50 or 60Hz, so it operates on mains supplies worldwide without a separate converter. No efficiency or temperature-rise figures are provided for continuous maximum-load operation.

Installation and common issues

Connection is magnetic: the tip snaps into place right-side-up or upside-down without precise alignment, and the 4.92ft DC cable plus 4.92ft AC cord give flexible desk routing. The mini wall plug swaps onto the AC cord for compact travel use. The cord jacket is tested to roughly 20000 bend cycles to resist wear. The only notable constraint is the proprietary connector, which prevents use with non-Surface devices that lack the matching port.

Questions about this item

How warm does the 65W adapter get when it runs at 15V 4A all day?

The UL-certified design includes temperature controls, current protection and short-circuit protection to keep the unit within safe limits during continuous 65W output.

Which AC cord or wall plug must I already have to use the charger?

The package includes a 4.92 ft AC cord and a mini wall plug, so no separate mains cable is required.

Will the magnetic tip connect reliably to my Surface Pro 3 and Surface Book 2?

Yes, the magnetic connector supports automatic adsorption on both devices and works right-side up or upside down without aiming.
