myVolts A1798 102W 15V 6.33A AC adapter laptop battery

SKU CH-5JV9-AGRNF MPN A1798.

A 102W AC adapter delivering 15V 6.33A with a magnetic connector and a 5V 1.5A USB port, compatible with Surface Book 2, Pro and Laptop models

  • 102W output powers demanding Surface devices
  • 15V 6.33A matches original charger specifications
  • 100-240V input works worldwide without converter
  • 5V 1.5A USB port charges phone simultaneously
  • 2ft cord gives flexible desk placement

Purpose and audience

This 102W AC adapter replaces the original Microsoft Surface Book charger for Surface Book 2, Surface Pro 3 through 7, Surface Pro X, Surface Go and Surface Laptop 2 through 4. It suits owners who need a new power supply when the factory unit has failed or been lost.

Bundled accessories and their effect

A 6.2ft mains cord is included so the adapter reaches distant sockets without an extension lead. An extra USB port supplies 5V at 1.5A, letting a phone or small accessory charge from the same brick while the laptop draws 15V at 6.33A.

Fit and alternatives

Buyers with the listed Surface models gain a direct magnetic connection that snaps into place and automatic thermal, overload and short-circuit protection. Users of other laptop brands or older Surface devices not named above should look elsewhere because the connector and voltage will not match.

Questions about this item

Will the magnetic connector on the A1798 adapter wear out and need replacing?

The magnetic connector snaps into place for easy attachment and is designed for repeated daily use without a specified replacement interval.

What is the first limit reached when the adapter runs at 102W continuously?

Automatic thermal and overload cut‑off protection activates first to protect the unit and connected device during sustained maximum output.

How much heat or noise does the 15V 6.33A supply produce when powering a Surface Book all day?

The adapter includes automatic thermal protection and has no fan, so it runs silently while managing heat through its built‑in safety cut‑off.
