Fervit USB-C to DC 5.5×2.5 mm Power Cable

This 20 cm cable connects a USB-C port to a 5.5×2.5 mm DC barrel jack. It is designed for users who want to power compatible devices from a USB-C charger or power bank. The short length keeps the setup tidy on a desk or in a bag. It suits MacBook owners and anyone with a matching DC input device.

Replacing a proprietary AC adapter

The cable replaces a bulky original power brick when you already own a suitable USB-C power adapter rated for 14.5 W at 2 A or 5 V at 2.5 A. The upgrade is worth it if you travel light and prefer a single charger for multiple gadgets. It does not increase charging speed beyond the adapter's own limits. Buyers who need longer reach or a different barrel size cannot use this cable.

Check your device and charger first

Verify that your device accepts power through a 5.5 mm outer and 2.5 mm inner diameter DC jack with the correct polarity. Confirm your USB-C charger delivers either 14.5 W at 2 A or 5 V at 2.5 A to match the cable's specified use case. The cable itself does not convert voltage or negotiate power profiles. Ensure the USB-C port on your charger supports the required output before ordering.

Questions about this item

What DC jack size does the 5.5×2.5 mm connector on this cable accept?

The barrel plug is 5.5 mm outer diameter and 2.5 mm inner diameter, matching the standard DC jack used by many laptop power adapters.

How do I connect the cable so the USB-C end negotiates power correctly?

Plug the USB-C end into the host device first, then insert the DC 5.5/2.5 mm plug into the adapter; reversing the order can prevent the 14.5 W / 2 A or 5 V / 2.5 A handshake.

Will the 20 cm length strain the USB-C port if the adapter hangs from a wall socket?

At 20 cm the cable is short; support the adapter with a desk clip or lay it on a surface so the USB-C port carries no hanging weight.
