65W Surface Magnetic Charger

This 65W AC adapter delivers 15V at 4A through a magnetic Surface connector and includes a USB Type-A port rated at 5V 1A. It replaces Microsoft chargers rated at 24W, 36W, 44W and 65W for Surface Pro 3 through 11, Pro X, Surface Laptop 1 through 6, Surface Book 1 through 3 and Surface Go 1 through 3.

Upgrade From Lower-Wattage Adapters

The adapter supplies 65W output, reducing charge time for compatible devices such as the Surface Pro 8 to roughly 90 minutes from empty compared with 24W, 36W or 44W units. It is not suitable for devices that require more than 65W or a different voltage profile.

Plug-In Magnetic Connection

Installation is limited to aligning the magnetic tip with the device charging port and plugging the IEC C7 mains lead into a 100-240V outlet. The fixed cable and non-detachable connector mean cable damage requires full unit replacement; no internal configuration or driver setup is involved.

Questions about this item

What connector does the 1735 65W adapter use to attach to a Surface device?

It uses the magnetic Surface Connector that snaps onto the charging port of compatible Pro, Laptop, Go and Book models.

What is the correct order for connecting the 1735 charger so the magnetic tip seats properly?

Plug the AC cord into the adapter brick first, then into the wall outlet, and finally attach the magnetic tip to the Surface — reversing the order can leave the tip loose.

Which user-replaceable part of the 1735 kit is most likely to wear out first?

The detachable AC power cord is the only user-replaceable component; the brick and magnetic tip are sealed and not serviceable.
