GCROWN 15V 4A 65W AC adapter with USB 2.0 port

SKU CH-WTW4-A7XN2

A 65W AC adapter for Microsoft Surface devices with a USB 2.0 port for simultaneous phone charging

  • Battery TypeLithium-Ion
  • Charge phone and laptop together via extra USB 2.0 port
  • Works with Surface Laptop 1, 2, 3 and Pro 3 through 7
  • Powers 65 W, 44 W, 36 W and 24 W models
  • Built-in IC chip guards against overcharge, short-circuit and overheat
  • Worldwide 100-240 V input lets you travel without a converter

Surface-compatible 65W adapter

This 15V 4A AC adapter powers Microsoft Surface Laptop 1, 2 and 3, Surface Pro 3 through 7 and X, Surface Go 1 and 2, Surface Book 1 and 2 and Surface Laptop Go. It replaces the original supply for any of those devices that require 65W, 44W, 36W or 24W at 15V or 12V. The unit ships new with a detachable mains cord.

Thermal and power behaviour

The adapter accepts 100-240V at 50/60Hz and delivers a steady 65W main output. A built-in IC provides over-charge, short-circuit, overload and over-heat protection, keeping the housing within safe limits during continuous operation. No active cooling is used, so the unit runs silently. An extra USB 2.0 port supplies 5V at 1.5A for charging a phone or accessory simultaneously.

Upgrade considerations

Owners of lost or damaged original Surface chargers can restore full charging speed with this unit. The additional USB port removes the need for a separate wall wart when travelling. Buyers whose devices demand more than 65W or a different voltage profile cannot use this adapter. Users needing USB-C Power Delivery or faster phone charging should look elsewhere.

Questions about this item

How do I connect the adapter and what is the common mistake with the USB port?

Plug the IEC C7 power cord into the adapter, connect the magnetic tip to the Surface device, then insert the mains plug. The USB port supplies only 5V 1.5A, so do not expect fast charging for phones.

Which parts will need replacement over time?

The detachable IEC C7 power cord and the magnetic DC cable can wear from repeated bending; the adapter body itself has no user-serviceable parts.

What limits sustained output before protection activates?

Continuous draw at 15V 4A (65W) plus the USB 5V 1.5A load triggers the built-in over-heat and overload safeguards, which shut the unit down until it cools.
