Power adapter for Surface devices

The GCROWN 1706 is a 65W AC adapter built for Microsoft Surface laptops and tablets including the Surface Pro 3 through Pro 8, Pro X, Surface Book, Surface Book 2, Surface Laptop, Surface Laptop 2, Surface Laptop 3, Surface Laptop Go and Surface Go models. It accepts a 100-240V 50/60Hz input and delivers up to 15V 4A for 65W output. A built-in USB port allows simultaneous charging of a phone or other USB device while the laptop is powered.

Buyers needing multi-voltage output

This unit suits owners who want a single charger that covers 65W, 44W, 36W and 24W Surface models and adds a USB-A port for a phone. It is not for users whose device requires a higher wattage than 65W or a different connector type. Buyers who need a pure USB-C Power Delivery brick without the proprietary Surface connector should look elsewhere.

Sustained output with thermal protection

The adapter maintains its rated 65W output through a built-in heat-dissipation system and an IC chip that guards against overload, short-circuit and overheat conditions. Charging efficiency reaches 96 percent, allowing most compatible laptops to reach full charge in roughly two hours. The protection circuitry remains active during continuous high-load operation to keep temperatures stable.

Questions about this item

Which Surface models will the 15V 4A 65W output charge?

The adapter supports Surface Pro 3 through Pro 8, Pro X, Surface Laptop 1 to 3, Surface Go and Go 2, Surface Book and Book 2, and Surface Laptop Go.

Can I keep using my older 44W or 36W Surface power supply cables with this unit?

Yes, the charger negotiates 15V 2.58A 44W, 12V 2.58A 36W and 15V 1.6A 24W automatically, so legacy cables work without change.

How do I confirm the built-in USB port is delivering power while the laptop charges?

The USB port supplies 5V power simultaneously; plug a phone in and its charging indicator will light while the Surface draws 65W from the main tip.
