## Summary description

Unitek Y-C4046BK power cable converts USB power to a DC barrel plug 5.5×2.5 mm with a 9V output.

## Long description

The Unitek Y-C4046BK power cable converts a USB power source to a DC barrel plug (5.5×2.5 mm) and provides a fixed 9V output for devices that accept a 5.5×2.5 mm DC input. It is intended to deliver power from standard USB ports or USB power adapters to small electronics such as routers, audio equipment, CCTV cameras and other compatible devices. The cable enables a simple USB-to-DC power connection without requiring the original AC adapter when a USB power source is available.
Advantages
The cable offers a compact and straightforward USB-to-DC solution that reduces the need for multiple dedicated power adapters. Its 5.5×2.5 mm DC plug fits devices designed for that barrel size and the 9V output matches devices that require that voltage level. The product is suitable for temporary or portable setups where USB power is more convenient than an AC outlet.
Suitable for
Powering routers and network devices with a 5.5×2.5 mm DC input
Supplying audio equipment that accepts a 9V DC barrel connector
Providing power to CCTV cameras and surveillance accessories with matching barrel jack
Temporary or portable use where USB power is available instead of an AC adapter
Key specifications
Connector type: USB (input) to 5.5×2.5 mm DC barrel plug (output)
Output voltage: 9V DC
Compatible plug size: 5.5 mm outer diameter × 2.5 mm inner diameter
Intended application: powering small electronics that accept 5.5×2.5 mm DC input
How to use
Connect the USB end of the Unitek Y-C4046BK cable to a USB power source such as a computer USB port, USB power bank, or USB wall adapter capable of supplying adequate current. Insert the 5.5×2.5 mm DC plug into the device’s DC input jack, ensuring correct polarity and a secure fit. Verify that the connected USB power source can provide the necessary current for the device and that the device is designed to accept a 9V DC supply before powering on.
Usage recommendations
Use a USB power source that can reliably supply the required current; check the device's power consumption beforehand. Avoid forcing the DC plug into incompatible jacks and do not use the cable with devices that require different voltages or polarities. For continuous or high-current applications, prefer the original manufacturer adapter designed for the device.
