White rectangular 65W power brick with USB port and detachable 3.3 ft AC cord

GCROWN

GCROWN 1706 65W AC adapter with USB port laptop battery

SKU CH-K0PF-GD6FT MPN 1706

65 W charger for Surface Pro 3, 4, 5, 6, 7, 8, 9, X and Surface Book with an extra USB port for simultaneous phone charging

  • Battery TypeLithium-Ion
  • Charges Surface Pro 3 to 9 and X at 65 W
  • Extra USB port powers a phone at 5 W simultaneously
  • Built-in thermal, overload and short-circuit protection
  • Works worldwide on 100–240 V mains
  • Includes 3.3 ft AC cord for flexible placement

Target Device & Use

This 65 W AC adapter is built for Microsoft Surface Pro 3, Surface Pro 4 and Surface Book model 1706. It also supports 24 W, 36 W and 44 W variants, so one charger covers several generations of those devices. A built-in 5 V 1 A USB port lets you top up a phone or accessory while the laptop charges.

Decisive Specification

The unit delivers 15 V at 4 A for 65 W total output, matching the original power requirement for the listed Surface models. Input accepts 100–240 V at 50/60 Hz, making it suitable for worldwide mains voltages without a separate converter.

Sustained-Load Behaviour

Automatic thermal, overload and short-circuit protection shut the adapter down before components overheat during continuous operation. The 3.3 ft AC cord and 6.6 ft DC cable give enough reach to keep the brick on a cool surface rather than trapped behind furniture.

Questions about this item

What does the 65 W output mean when I plug this into my Surface?

The adapter delivers 15 V at 4 A for a total of 65 W, powering compatible Surface Book and Surface Pro models while also running the extra USB port.

How does the USB port’s 5 V 1 A limit affect what I can charge?

The port supplies up to 5 W at 5 V and 1 A, so it can charge a phone or small accessory but not a tablet or another laptop.

What length is the AC cord and will it reach a desk outlet?

The included US LISM AC cord is 3.3 ft long; the supplier title also mentions a 6.6 ft cord option for longer reach.
