Purpose and audience

This 65W Surface charger replaces the original power supply for Microsoft Surface Laptop 1 through 6, Surface Pro 3 through 11 and X, Surface Book 1 through 3, Surface Go 1 through 3, and Surface Laptop Studio. It includes a USB Type A port that delivers 5V at 1A for charging a phone or accessory while the laptop is powered.

Thermals noise and power

The adapter accepts 100-240V at 50-60Hz and supplies 15V at 4A for the main output, plus 5W from the USB port. It is built with overvoltage and short-circuit protection and has been tested for stable operation under normal load. No active cooling is used, so the unit runs silently.

Deciding specification

The connector is a USB Type A plug that mates with the proprietary Surface charging port; it will not fit devices that require USB-C Power Delivery or the newer 127W Surface connector. Buyers whose Surface model uses a different connector cannot use this adapter.

Questions about this item

How do I connect the AC cord and the Surface connector without reversing the polarity?

Plug the AC cord into the brick until it clicks, then insert the magnetic Surface connector straight into the device port — the magnets only engage one way, preventing reverse insertion.

Which part of the YBRUZRUB SK90150400 will wear out first and need replacing?

The detachable AC cord and the magnetic tip on the Surface connector are the only moving parts; the cord can be swapped separately if the strain relief frays.

What stops the charger from delivering full 65 watts during a long session?

The built-in over-voltage and short-circuit protection will throttle output if the brick overheats, so sustained 65 W requires adequate airflow around the 3.54 x 1.97 x 0.98 in enclosure.
