SMUGDESK USB-C Female to DC 5.5×2.1mm Female Power Adapter Cable

SKU CH-J1JD-X6WNA

Converts a USB-C power source to a 5.5×2.1 mm barrel jack for routers, LED strips and DIY projects

  • Converts USB-C power to DC 5.5×2.1mm barrel jack
  • Power-only design with no data signal transmission
  • Low voltage loss from high-conductivity wire core
  • Works with routers, LED strips, CCTV cameras and DIY projects
  • Lightweight flexible cable for easy wiring and portable use

Power conversion for portable gear

This USB-C female to DC 5.5×2.1mm female adapter cable converts a Type-C power source into a standard 5521 barrel jack. It is built for power transmission only and does not carry data signals. The compact moulded connectors and flexible wire keep voltage loss low. It suits routers, LED strips, CCTV cameras and DIY portable power projects.

Capacity and headroom

The cable passes the voltage and current your Type-C supply delivers up to the limits of the 5.5 mm outer and 2.1 mm inner barrel dimensions. It handles typical router, LED lighting and small camera loads without noticeable heat rise. It runs out when the attached device draws more current than the source or the barrel connector rating allows.

Replaces fixed barrel cables

It upgrades setups that rely on a dedicated barrel-plug power brick by letting you use a USB-C charger or power bank instead. The jump is worth it when you want one versatile Type-C supply for multiple 5521 devices or need a lightweight cable for outdoor and DIY wiring. It is not for buyers who need data transfer or a locking connector.

Questions about this item

Will this adapter work with my existing router that uses a 5.5×2.1 mm barrel jack?

Yes, the cable converts a USB-C power source to a 5.5 mm outer diameter and 2.1 mm inner diameter barrel jack, matching the standard port on many routers.

How can I verify the cable is delivering power correctly after connecting it?

The connected device should power on normally; the adapter is built with high-conductivity wire and solid insulated terminals to provide stable current with low voltage drop.

What comes in the package and do I need to buy a separate USB-C power supply?

The package contains only the USB-C female to DC 5.5×2.1 mm female adapter cable; a USB-C power source must be supplied separately.
