What this adapter delivers

The 2-Power A1798 supplies 102W at 15V 6.33A through a magnetic DC connector and adds a 5V 1.5A USB-A port for simultaneous phone charging. Input accepts 100-240V AC. Both AC and DC cables measure 5.9ft. The brick weighs 0.3kg and measures 4.3 by 2.1 by 1.2in.

The single spec that decides fit

Output must be 15V 6.33A with the magnetic Surface connector; this unit matches that exactly and also replaces 65W, 44W, 36W and 24W Surface chargers listed in the data. If your device requires a different voltage or connector, this adapter will not work.

Who should buy it and who should not

Owners of Surface Book 1-3, Laptop 1-5, Laptop Studio, Laptop Go, Pro 3-9, Pro X or Go 1-3 needing a 102W replacement with a spare USB-A port. Buyers whose device uses a non-magnetic barrel jack or a USB-C PD input should look elsewhere.

Questions about this item

What does the 102W rating mean when the adapter is connected to a Surface Book or Laptop?

The adapter can deliver up to 102W total, with 15V at 6.33A on the DC connector for the laptop and 5V at 1.5A on the USB-A port for a phone or accessory simultaneously.

How does the magnetic DC connector limit charging speed on supported Surface models?

The connector carries 15V at up to 6.33A, so the laptop draws whatever current it requires up to that limit; the adapter does not force a higher rate than the device requests.

What clearance is needed for the brick and cables to sit on a desk without strain?

The brick measures 4.3in by 2.1in by 1.2in and weighs 0.3kg; both the AC and DC cords are 5.9ft long, giving ample reach from a wall outlet to the device.
