DC 7.9 x 5.5mm to USB-C Power Adapter

This adapter converts a USB-C power source into a 7.9 x 5.5mm DC barrel jack. It supports power delivery profiles up to 65W for compatible devices. The unit is built with an ABS housing measuring 70x30x17mm. It is intended for users who need to power legacy equipment from a modern USB-C charger.

Plug-and-play connectivity with 15cm cable

A fixed 15cm USB-C cable connects the adapter to the power supply, requiring no extra cables. The female barrel jack accepts a standard 7.9 x 5.5mm plug from the target device. It draws power directly from any USB-C PD source that meets the required voltage. No drivers or configuration are needed for operation.

Sustained 65W output within supported profiles

The adapter maintains continuous delivery at 5V/3A, 9V/3A, 12V/3A, 15V/3A and 20V/2.25A when the input provides at least 20V. It does not amplify power beyond the source capability. Users needing higher amperage at 20V or different barrel sizes cannot use this model. Thermal performance relies on the compact ABS enclosure without active cooling.

Questions about this item

What is the maximum power draw the 7.9 x 5.5 mm jack can sustain without overheating?

The adapter is rated for 65 W continuous output, matching the highest 20 V/2.25 A profile, so sustained loads up to that level stay within its thermal design.

Does the 15 cm cable and ABS housing stay cool and quiet during all-day operation?

With no moving parts and a short 15 cm cable, heat remains low at the rated 65 W; the ABS body dissipates warmth passively and produces no audible noise.

Which USB-C charger must I already own to deliver the full 65 W through this adapter?

You need a USB-C Power Delivery charger capable of 20 V at 2.25 A or higher — any 65 W or greater PD brick with that voltage step will drive the adapter to its full rating.
