faibia EADP-1798 102W 15V 6.33A ac adapter

SKU CH-K1CS-3DD8A MPN EADP-1798

102 W, 15 V, 6.33 A AC adapter with USB port charges Microsoft Surface Book 2 models 1798 and 1703 worldwide on 100–240 V input

  • Delivers 102W for fast Surface Book charging
  • 15V 6.33A output matches original power requirements
  • Works worldwide with 100-240V AC input
  • Includes 6ft power cable for flexible placement
  • USB port charges a second device simultaneously

Purpose and compatibility

This 102W AC adapter is built for Microsoft Surface Book and Surface Book 2 models including the 1798 and 1703 variants. It delivers a steady 15V at 6.33A to recharge the internal battery and run the device simultaneously. A USB port on the brick lets you charge a phone or accessory at the same time.

Thermals noise and power draw

The unit accepts a universal 100-240V AC input for worldwide use without a voltage switch. In normal operation it converts mains power to the rated 102W DC output with no audible fan noise. The compact brick stays warm but not hot during typical charging and office workloads.

Sustained load behaviour

Under continuous maximum draw the adapter maintains its 15V 6.33A specification without throttling or shutdown. The six-foot detachable AC cable gives flexible desk placement while the fixed DC lead reaches the Surface connector reliably. It is not suited for devices that require higher wattage or a different voltage profile.

Questions about this item

How do I connect the 15V 6.33A adapter to my Surface Book 2 1798, and which step do people often miss?

Plug the AC cable into the brick, then the barrel connector into the Surface charging port; the step many miss is seating the barrel fully until the magnetic alignment clicks, otherwise charging will not start.

What part of the 102W EADP-1798 will need replacement first with daily use?

The detachable 6 ft AC cable and the barrel-tip connector see the most physical stress; the cable insulation or tip spring usually wears out before the internal power circuitry.

At what point does the 15V 102W charger hit its thermal limit during a long render?

Sustained 102 W output at 15 V 6.33 A will trigger the internal over-temperature protection first; the unit throttles or shuts down until the case cools enough to restart.
