Magnetic 65W adapter for Surface devices

This 65W magnetic AC adapter supplies 15V at 4A to compatible Microsoft Surface Pro, Laptop, Go and Book models. It accepts a worldwide 100-240V input so it works across regions without a voltage converter. The unit includes a USB 2.0 port rated at 5V 1A for charging a phone or accessory at the same time. It is a new replacement power supply built to UL, FCC and RoHS safety standards.

Magnetic connector with integrated USB port

The magnetic tip seats firmly and resists accidental disconnection during daily use. A built‑in USB 2.0 port lets you top up a second device without carrying an extra charger. Over‑charge, short‑circuit, overload and over‑heat protection circuits guard both the adapter and the connected hardware. The package supplies the power brick and a detachable AC cord for immediate setup.

Limits of the 15V 4A output

The fixed 15V 4A output only suits devices designed for that exact voltage and current profile. The single USB 2.0 port delivers just 5W, so it cannot fast‑charge modern phones or power hungry peripherals. Proprietary magnetic connectors prevent use with laptops that require USB‑C Power Delivery or barrel jacks. Buyers needing higher wattage, adjustable voltage or multiple high‑speed ports will need a different solution.
