Unitek USB cable model 4894160026613 is a 20.0 m USB-A to USB-A cable in black designed for extended wired connections between devices with standard USB-A ports. The cable provides a simple solution when longer reach is required for linking computers, peripherals, AV equipment or control devices while maintaining a familiar USB-A interface for data transfer and power delivery consistent with the USB-A standard.
Advantages
The cable’s 20.0 m length enables installations where standard short cables are not sufficient, reducing the need for intermediate repeaters or extra adapters. Its USB-A to USB-A connectors keep compatibility with a wide range of legacy and current devices that provide or accept USB-A connections. The black jacket gives a neutral appearance suitable for office, AV and rack-mounted environments.
Suitable for
- Connecting computers to peripherals over extended distances in offices or workspaces
- Audio-visual setups where devices with USB-A ports are placed far apart
- Equipment racks and control cabinets requiring longer USB-A cabling
- Temporary installs or events where a single long USB-A lead simplifies wiring
When it may not be suitable
This USB-A to USB-A cable is intended for use with devices that accept direct USB-A connections; it may not be suitable where device manufacturers advise against direct host-to-host USB-A connections or where a USB-A to USB-B, USB-C or other connector type is required. Very long passive USB cables can be subject to signal degradation and reduced power delivery compared with shorter or active/boosted solutions, so performance depends on the connected devices and their USB interface specifications.
Key specifications
- Cable type: USB-A to USB-A
- Length: 20.0 m
- Color: Black
- Use: Data transfer and power delivery within USB-A interface limits
- Typical applications: Office wiring, AV setups, equipment racks
How to use
Connect one USB-A plug to the host or source device and the other USB-A plug to the peripheral or target device. Ensure both devices are powered and configured for the intended data or power role. For best results, avoid sharp bends, kinks or tight coils in the long cable and route it away from strong electromagnetic interference sources. If a particular device requires a dedicated upstream or downstream port or a specific cable type for host-to-host connections, follow the device manufacturer’s guidance.
What to consider before purchase
- Confirm both devices support USB-A to USB-A connection and the required data/power roles
- Assess whether a passive 20 m cable meets your signal integrity and power delivery needs or if an active/boosted cable or repeater is required
- Check physical routing constraints and mounting points for a 20.0 m cable
Usage recommendations
Use this 20.0 m USB-A to USB-A cable for installations where convenience and reach are the primary needs. For mission-critical data transfer or where higher power is required, consider testing the connection under real-world conditions or using an active cable or intermediary device to maintain signal and power performance.
