SKU CH-JT71-0SYTK MPN A1706.

A 65 W AC adapter with magnetic connector and extra USB port for Microsoft Surface devices

  • TypeAC Adapter
  • 65 W output powers compatible Surface devices
  • 15 V 4 A delivery matches original charger specs
  • Extra USB port charges phone at 5 V 1 A
  • Magnetic connector snaps on for quick attachment
  • 100–240 V input works worldwide at 50 / 60 Hz

Replacement AC Adapter for Surface Devices

This 65W adapter replaces the original Microsoft power supply for Surface Pro 3 through 9, Surface Pro X, Surface Laptop 1 through 3, Surface Book and Surface Go. It accepts 100-240V input at 50 or 60 Hz and delivers 15V at 4A. The unit is new and carries model number A1706.

Extra USB Charging Port

A built-in USB port supplies 5V at 1A so you can charge a phone or other accessory while the Surface is powered. This removes the need for a separate wall charger for that second device. The magnetic connector snaps onto the device for quick attachment.

Safety Protections and Cord Length

Automatic thermal, overload and short-circuit protection cut power when a fault is detected. A 6ft power cord gives flexibility in outlet placement. The adapter is intended for the listed Surface models only and is not suited for devices requiring a different voltage or connector type.

Questions about this item

How long before the magnetic connector or internal protection circuits need replacement?

The magnetic connector snaps securely for repeated attachment, and built-in automatic thermal, overload cut-off, and short-circuit protection are designed to operate continuously without scheduled replacement.

What limits continuous output when the adapter runs at full 65W load?

The unit delivers a fixed 15V 4A output; sustained operation at 65W is constrained by the thermal and overload cut-offs that activate if temperature or current exceed safe thresholds.

How much heat and fan noise does the charger produce during all-day use?

No fan is present; the adapter relies on passive cooling, so it runs silently while the automatic thermal protection manages heat during extended 65W operation.
