  • Charges Surface Pro 3-9, Book 1-2, Go 1-3 via magnetic connector
  • Delivers 65 W at 15 V from compatible USB-C charger
  • Requires USB-C charger supporting 15 V-24 V output range
  • Connects Rectangle Thinpad X1 jack to Surface magnetic port
  • New Fervit cable enables DC charging from USB-C source

Compatible Surface Models

This cable connects a rectangular ThinkPad X1 power jack to Surface devices that use the magnetic charging connector. It supports Surface Pro 3 through Pro 9, Surface Book 1 and 2, and Surface Go 1 through 3. The adapter delivers a fixed 15 V DC output at up to 65 W. It is intended for users who already own a compatible USB-C or DC charger.

Voltage Requirement For Source Charger

The connected charger must be capable of supplying 15 V to 24 V output; a source limited to 5 V or 9 V will not work. Buyers whose only power bricks provide fixed lower voltages should look elsewhere. The cable itself does not convert voltage — it passes the source voltage through to the Surface connector. Ensure your charger explicitly lists 15 V or higher in its PDO profile.

Mandatory 15 V to 24 V Source Capability

The single specification that determines whether this cable will function is the source charger’s ability to output 15 V to 24 V. Without that voltage range the magnetic connector receives insufficient potential and the Surface device will not charge. Check the charger’s label or specification sheet for 15 V, 20 V or 24 V support before purchasing.

Questions about this item

Will the magnetic connector or the rectangular plug wear out first with daily use?

The cable uses a Surface magnetic connector on one end and a rectangular Thinpad X1 jack on the other; both are passive connectors with no moving parts, so neither has a rated replacement cycle.

What voltage limit stops the cable from working if my charger cannot supply it?

The cable requires the USB-C charger to support 15 V to 24 V output; if the charger only provides lower voltages the cable will not function.

Does the cable get hot or draw extra power when charging a Surface Pro 9 all day?

The cable is a passive 65 W adapter with no active electronics, so it adds no measurable heat or power draw beyond what the charger and laptop negotiate at 15 V.
