127W Surface adapter with magnetic plug
The 2-Power MDSF127 delivers up to 127W to Microsoft Surface Book, Laptop Studio, Pro, Laptop and Go models. It negotiates 102W, 65W, 44W, 39W, 36W or 24W automatically, so one brick replaces several original chargers. A 10-foot cable and strong magnetic tip let you connect without hunting for the port. The adapter also supplies a USB port for charging a phone or tablet at the same time.
Sustained multi-device charging behaviour
Under continuous load the unit maintains the negotiated power level without throttling, keeping a Surface battery rising even during gaming or video editing. The 85W continuous rating supports demanding laptops while the USB output stays active for a second device. Internal temperature monitoring protects both the adapter and the connected hardware during long sessions.
Simple magnetic connection and cable care
The magnetic connector snaps on without alignment effort and releases safely if the cable is pulled. The 10-foot length uses thicker copper conductors rated for over 20000 bends, reducing wear at the strain points. A blue LED confirms power delivery at a glance. Buyers who need a barrel-style tip or a higher single-port wattage will not be served by this design.

Questions about this item
How much heat or noise does the MDSF127 produce when charging a Surface Book 3 at full load all day?
The 127W charger uses passive cooling with no fan, so it runs silently; under continuous maximum output the brick becomes warm but stays within normal operating temperature for a compact AC adapter.
What must I already own to use the USB charging port on this adapter?
You need a USB cable that matches your phone or tablet — USB-C to USB-C, USB-C to Lightning, or USB-A to whatever port your device uses — because the adapter only supplies the USB-A port itself.
Will the 127W MDSF127 work with my original 65W Surface Pro 4 charger brick and magnetic tip?
Yes, the magnetic connector fits the same Surface Connect port used on the Pro 4, and the adapter automatically negotiates 65W, 44W, 39W, 36W or 24W to match the older device’s requirement.
