Replacement charger for Surface devices

This 44W AC adapter replaces the Microsoft Model 1800 supply for Surface Pro 3 through 7, Surface Pro X, Surface Book, Surface Go and Surface Laptop 1 to 3. It delivers 15V at 2.58A from a 100 to 240V input and includes a 5V 1A USB port for charging a phone at the same time. The unit is new and built as a direct replacement when the original adapter fails.

Magnetic connector and 6ft cable

The magnetic tip snaps into the device for quick attachment and releases under strain to protect the port. A 6ft power cord gives flexibility in outlet placement without needing an extension lead. Output is limited to 44W, so devices that draw more power will not charge at full speed while under heavy load.

Safety protections and daily use

Automatic thermal, overload and short-circuit cut-offs interrupt power if the adapter overheats or a fault occurs. The extra USB port adds convenience for a second device but shares the same brick, so total draw remains within the 44W rating. Buyers who need higher wattage for larger Surface models or simultaneous fast charging of two power-hungry devices should look for a higher-rated supply.
