USB-C to 5521 DC power adapter

This cable converts a USB-C male port into a 5.5×2.1mm female DC jack, letting you power compatible devices from a USB-C source. It is intended for users who need to run routers, CCTV cameras, LED strips or similar low-voltage equipment from a USB-C power supply.

Thick copper conductors and flexible insulation

The cable uses thickened copper cores to maintain steady current delivery and reduce loss during power transmission. A durable insulated jacket protects against repeated bending, while the compact form factor keeps desktop wiring tidy and suits portable use.

Power-only connection with fixed connector size

This adapter carries only power and does not transmit any data signals. It works solely with equipment that accepts a 5.5mm outer and 2.1mm inner diameter DC plug, so devices with different barrel sizes cannot be connected.
