DC 4.5×3.0 mm to Surface Magnetic Cable

This Fervit cable converts a 4.5 mm × 3.0 mm DC barrel jack into a Surface Magnetic Connector for charging compatible devices. It accepts a 65 W power source that can deliver 15 V to 24 V output and provides a fixed 15 V feed to the Surface side. The adapter suits owners of Surface Pro 3 through Pro 9, Surface Book 1 and 2, and Surface Go 1 through 3 who want to use an existing DC charger. It is a new cable built for direct DC-to-Surface power delivery.

Who should use this and who should not

Buyers with a 65 W DC charger that supports 15 V–24 V output and a Surface model listed above can use this cable to charge from that charger. It will not work if the power source cannot supply at least 15 V over the DC jack, so USB-C chargers limited to 5 V or 9 V profiles are unsuitable. Users needing Power Delivery negotiation, variable voltage output, or data transfer should look for a different solution because this cable passes only fixed 15 V power.

Critical specification: 15 V–24 V input requirement

The power source connected to the 4.5 mm × 3.0 mm jack must be a 65 W charger capable of 15 V to 24 V output; otherwise the cable cannot deliver the 15 V the Surface Magnetic Connector expects. Verify your DC charger’s voltage range before purchase, as lower-voltage adapters will not activate the cable. This single voltage-compatibility check determines whether the cable will function with your existing power supply.

Questions about this item

How do I connect the 4.5x3.0mm jack to my charger and the magnetic end to my Surface?

Plug the 4.5x3.0mm jack into a DC charger that delivers 15-24V output, then attach the magnetic connector to the Surface charging port; the cable only works when the charger supplies the required voltage range.

Will the magnetic connector or the 4.5x3.0mm jack wear out and need replacing?

The magnetic connector and the 4.5x3.0mm jack are passive components with no moving parts; they typically last the life of the cable unless physically damaged.

What happens if I use a charger that cannot maintain 15-24V output during a long charging session?

The cable will stop delivering power to the Surface because it requires the charger to sustain 15-24V output; if voltage drops below that range, charging ceases.
