Fervit 65W 20V 15V-24V DC 4.5x3.0mm Jack to Surface Magnetic Connector Cable

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.
