Broad Surface Compatibility

This 65W AC adapter model MDSF65 delivers 20V output at 11.8A for Microsoft Surface Pro models 3 through 11, including Pro X and 7+. It also supports Surface Laptop 1 through 7, Laptop Go 1 through 3, Book 1 through 3, Go 1 through 3, Studio 1 i5, and 13.8-inch and 15-inch Laptop variants. The magnetic connector and blue LED indicator simplify alignment and show charging status at a glance.

Replaces Lower-Wattage Chargers

The 65W output fully charges a Surface Pro 8 in 1.5 hours, outperforming lower-wattage alternatives that extend charge times. Built-in protections guard against overcharging, overheating, and short-circuiting to preserve battery health. The 10-foot corded electric cable adds reach for desk, sofa, or travel setups where the original shorter lead falls short.

Simple Magnetic Installation

Snap the magnetic tip onto the device charging port; the LED confirms connection instantly. No drivers or configuration are required. The only common issue is debris on the magnetic contacts preventing a firm seat — wipe both sides clean if the LED fails to light. The adapter weighs 6.34 ounces and measures 14.33in W x 12.83in H x 9.06in D.
