myVolts 1625 44W 15V 2.58A laptop battery

SKU CH-TD2D-K8R31 MPN 1625

A 44W 15V power adapter with USB charging port for Microsoft Surface Pro and Laptop models

  • 44W output recharges Surface devices quickly
  • USB-A port charges a phone at the same time
  • 100-240V input works worldwide without a converter
  • 6ft DC cable plus 3.3ft AC cord give flexible placement
  • Thermal, overload and short-circuit protection keeps charging safe

Compatible Surface power adapter

This 44W adapter replaces Microsoft model 1625 and 1735 units and supports Surface Pro 3 through 7, Surface Book, Surface Laptop 1 to 3, Surface Laptop Go and Surface Go 1 to 3. The magnetic connector snaps into place for a secure charging connection. A built-in USB-A port supplies 5V at 1A so a phone or accessory can charge at the same time.

Check your device and mains supply

Verify that your Surface device appears in the compatibility list above before ordering. The adapter accepts AC input from 100V to 240V at 50Hz or 60Hz, making it suitable for worldwide use. Ensure you have a standard IEC C7 mains socket for the included 3.3ft AC cable.

Build quality and daily use

The compact brick measures 4.3 by 2.1 by 1.0 inches and includes a 6ft DC cable for flexible desk placement. Automatic thermal, overload and short-circuit protection cut power if a fault is detected. The magnetic tip aligns easily in low light, and the extra USB port keeps a second device topped up without a second charger.

Questions about this item

What cables come with the 1625 charger and do I need a separate AC cord?

The box includes a 6 ft DC cable attached to the charger and a detachable 3.3 ft AC cord, so no extra mains cable is required.

The specs list 44 W, 36 W and 24 W outputs — which one will my Surface actually draw?

The charger negotiates with the device; it can deliver 15 V at 2.58 A (44 W), 12 V at 2.58 A (36 W) or 15 V at 1.6 A (24 W) depending on what the connected Surface requests.

Will the 44 W rating charge a Surface Book as fast as the original supply?

Yes — the 1625 supplies the same 15 V 2.58 A (44 W) profile as the Microsoft 1800 model, so a compatible Surface Book charges at the original speed.
