DC 7.4x5.0mm Jack to Surface Magnetic Cable

This cable converts a DC barrel input into a Surface magnetic charging connector for compatible Microsoft tablets and laptops. It is designed for users who want to power Surface devices from a 65 W DC source that delivers 15 V to 24 V output. The 7.4 mm by 5.0 mm jack fits matching DC chargers and portable power stations.

Thermals noise and power draw

The cable itself is a passive assembly with no active electronics, so it generates no audible noise and adds negligible thermal load during normal use. Power delivery depends entirely on the connected DC charger, which must supply 15 V to 24 V at up to 65 W for the cable to function. No additional power draw is introduced by the adapter.

Replaces proprietary Surface power bricks

This cable replaces the need to carry a dedicated Surface power supply when a suitable DC source is already available. The upgrade is worthwhile for travelers or field technicians who standardise on a single 65 W DC charger supporting 15 V to 24 V output. It is not for users whose chargers lack the required voltage range or who need USB-C Power Delivery input.

Questions about this item

How do I connect the 7.4x5.0 mm jack to my 65W charger so the cable delivers 15 V to my Surface Pro 7?

Plug the 7.4x5.0 mm barrel into a DC charger that can output 15–24 V; the cable then presents a male Surface magnetic connector at 15 V. If the charger cannot supply that voltage range the cable will not work.

What part of this cable is most likely to wear out first with daily plugging and unplugging?

The magnetic Surface connector and the 7.4x5.0 mm barrel jack are the mechanical interfaces that see repeated insertion cycles; the cable body itself has no moving parts.

At what power level will this cable stop delivering charge if I run a sustained load on a Surface Book 2?

The cable is rated for 65 W input; if the combined system draw exceeds that limit the charger or cable will hit its ceiling first.
