Fervit 65W 20V DC 5.5x2.5mm Jack to Surface Magnetic Cable

SKU CH-3QXX-0RHMC

Charges Surface Pro 3-9, Book 1-2 and Go 1-3 from a 65 W DC 5.5x2.5 mm jack supplying 15-24 V

  • Charges Surface devices via standard DC barrel jack
  • Supports 15 V to 24 V input range for flexible power sources
  • Magnetic connector fits Pro 3 through 9, Book 1‑2, Go 1‑3
  • Delivers up to 65 W through 5.5 × 2.5 mm input
  • Requires charger capable of 15 V‑24 V output to function

Fervit 65W DC cable for Surface devices

This cable bridges a standard 5.5x2.5mm DC jack to the magnetic Surface charging port. It carries 20V at up to 65W and delivers 15V to compatible Surface Pro, Book and Go models. The connector fits devices from Pro 3 through Pro 9, Book 1 and 2, and Go 1 through 3. Use it with an existing DC power supply that meets the input requirements.

Suits owners replacing a lost proprietary brick

Buyers who already own a 65W DC adapter with 15V to 24V output can keep that charger and add this cable for Surface charging. It does not work with USB-C chargers or power banks that lack the required voltage range. Builders needing a standalone wall wart or a cable for non-Surface laptops should look at other products.

Voltage window decides compatibility

The source charger must provide a configurable 15V to 24V output through its 5.5x2.5mm jack; fixed-voltage supplies outside this window will not operate the cable. The cable itself passes 15V to the magnetic tip, so the upstream adapter determines whether charging starts.

Questions about this item

How do I connect the 5.5x2.5mm jack to my charger and what voltage must the source provide?

Plug the 5.5x2.5mm jack into a DC charger that can deliver 15V to 24V output; the cable will not work if the charger only supplies lower voltages.

Will the magnetic connector wear out and need replacement after repeated docking?

The magnetic Surface connector is a passive contact interface with no moving parts, so it does not have a scheduled replacement interval under normal use.

What happens if I run a 65W load continuously through the cable?

The cable is rated for 65W input; sustained operation at that level is within its design limit provided the charger maintains 15V-24V output.
