85W Surface Magnetic Charger

The 2-Power SK90150400 delivers up to 85W through a magnetic connector that fits Surface Pro models 3 through 11, Surface Laptop 1 through 7, Surface Book 1 through 3, Surface Go 1 through 3 and Surface Laptop Studio 13.8 and 15 inch devices. It also supplies 15V at 4A via a built-in USB-A port for charging phones or accessories. The unit is new and intended for owners who need a single adapter for multiple Surface devices.

Magnetic connector practical limits

The magnetic tip adsorbs automatically when brought near the device port and works right-side-up or upside-down without precise alignment. Output scales to 65W, 44W, 39W, 36W or 24W depending on the connected model, so maximum power is only reached with compatible devices that request it. The AC cable measures 6.2Ft and the DC cable 5Ft, limiting placement distance from the wall outlet.

Installation and common issues

Plug the AC cord into mains power, then bring the magnetic tip close to the Surface charging port; it snaps into place without force. No drivers or configuration are required. The most frequent issue is using the charger with a device that draws more current than the adapter’s negotiated profile, which results in slower charging or no charge at all. Cable strain near the connector can develop after thousands of connect-disconnect cycles.

Questions about this item

Should I pick the 65 W or 85 W version for my Surface Pro 9?

The adapter delivers up to 85 W at 20 V and 3.42 A, and will automatically negotiate 65 W, 44 W, 36 W or 24 W for each compatible model.

What does the 85 W rating actually give me on a Surface Laptop 5?

It provides the full 65 W the laptop requests while leaving headroom for the extra USB port, so charging stays at maximum speed even with a phone plugged in.

How does the magnetic connector limit charging speed?

The magnetic Surface connector handles the negotiated voltage up to 20 V and 3.42 A, so the 85 W ceiling is set by the adapter, not the plug.
