65 W charger with USB port

This 65 W AC adapter delivers 20 V at 11.8 A for compatible Microsoft Surface devices and includes an extra USB port for simultaneous charging of a second device. It is intended for owners of Surface Pro, Surface Laptop, Surface Book or Surface Go models who need a replacement or spare power supply. The unit automatically negotiates lower output levels of 44 W, 36 W, 24 W and others to match the connected device. It is not for users of Surface Laptop Studio i7 or Surface Laptop Studio 2.

Magnetic connector and power limits

The charger uses a magnetic DC plug that attaches only to the proprietary Surface charging port, so it cannot power laptops that rely on USB-C Power Delivery or barrel connectors. Maximum output is capped at 65 W, with additional fixed steps at 44 W, 39 W, 36 W and 24 W; it will not supply higher wattages demanded by larger workstations or gaming notebooks. The built-in USB port provides a 15 V, 4 A auxiliary output, but total combined draw cannot exceed the adapter’s 65 W ceiling.

Plug-in installation and common issues

Installation is plug-and-play: attach the magnetic tip to the device and connect the mains cable; an LED on the connector confirms the link. The unit includes automatic thermal, overload and short-circuit cut-offs that reset once the fault clears. The most frequent problem is attempting to charge an unsupported model such as Surface Laptop Studio i7 or Studio 2, which results in no power or an error message. Ensure the device appears in the listed compatibility series before use.

Questions about this item

Which 1706 charger version should I pick for my Surface Pro 9 and a phone?

The single 1706 model delivers 65 W through the magnetic plug and adds a USB port for a second device, so one unit covers both.

What does the 65 W rating actually give me on a Surface Laptop 7?

It powers the laptop at full speed while the extra USB port charges another gadget at the same time.

How does the magnetic DC connector limit what I can plug in?

The 20 V 11.8 A magnetic tip fits Surface Pro 3 through 11, Surface Laptop 1 through 7, Surface Book 1 through 3 and Surface Go 1 through 3, but not Surface Laptop Studio i7 models.
