UNITEK U304A USB-C to USB-A Active Extension Cable 5M 5Gbps with DC Jack for Webcam Microphone
The UNITEK U304A is an active extension cable. It extends USB connections up to 5 meters. The cable has a USB-C male plug on one end and a USB-A female port on the other. It supports USB 3.0 SuperSpeed data transfer at 5Gbps. This is ten times faster than USB 2.0. It is also backward compatible with USB 2.0 and 1.1 devices. The active chipset ensures stable signal integrity over the long 5‑meter distance.
The cable is built with premium materials. It has nickel‑plated connectors that resist corrosion. The aluminum alloy housing provides durability and heat dissipation. The 28AWG bare copper conductors maintain signal quality. An LED indicator shows the connection status at a glance. The cable is plug and play. No drivers are required for Windows, macOS, or Linux.
This extension cable includes an optional DC power jack (3.5mm x 1.35mm). You can connect an external 5V power supply (not included). This is necessary for high power‑consuming USB devices. Webcams, USB microphones, signal receivers, and external hard drives may need extra power. Without external power, the cable still works for low‑power devices.
Use this cable to extend the reach of your USB peripherals. Connect a webcam to a computer across a large room. Position a microphone for better audio capture. Place a printer or scanner farther from your desk. The UNITEK U304A delivers reliable, long‑distance USB connectivity.
