USB-C to 7.9 x 5.5 mm Adapter

This cable connects a USB-C power source to devices that use a 7.9 by 5.5 mm barrel connector. It serves as a compact charger adapter for compatible laptops, routers or other equipment. The unit weighs about 14 g and measures roughly 15 cm in length. It is supplied in new condition.

Suits owners of barrel-powered gear

Users who need to power 7.9 x 5.5 mm devices from a USB-C PD charger will find this adapter convenient. It is not for buyers who require a different barrel size, a right-angle plug or a longer cable run. The fixed length of about 17.5 cm limits reach, so setups needing extra slack should look elsewhere.

Check your device and charger first

Verify that the target device accepts power through a 7.9 x 5.5 mm centre-positive jack and confirm its voltage and current requirements. Ensure the USB-C source can deliver the needed power profile for that device. Polarity and power compatibility are not guaranteed by the adapter alone.

Questions about this item

Does my device need a USB-C power source to run from this 7.9 x 5.5 mm connector?

Yes, the cable draws power from a USB-C port or charger and delivers it through the 7.9 x 5.5 mm barrel plug.

Will the 17.5 cm length reach from a rear USB-C port to a desktop power brick?

At about 17.5 cm the cable suits close-range links; measure the gap between your USB-C outlet and the barrel socket before relying on it.

How can I confirm the adapter is passing power to my 7.9 x 5.5 mm device?

Connect the USB-C end to a live source, plug the barrel into the device, and verify the device powers on or its charging indicator lights.
