USB Superbooster Extender adapter MEGA C2G model 81621, black USB interface accessory

MEGA C2G USB Superbooster Extender adapter model 81621 is a compact black USB interface accessory that extends USB connectivity up to 45 metres using a standard Ethernet patch cable. The solution consists of a base unit and a remote unit connected by CAT5/CAT5e/CAT6/CAT6a cable (cable not included) and offers plug-and-play operation without drivers. The device is bus-powered and includes internal DC power conditioning to maintain proper voltage to the remote unit while remaining compliant with USB 1.1 specifications. Some high-power peripherals may still require external power.

Advantages

The Superbooster Extender provides a simple, driverless method to overcome USB cable length limitations and place USB peripherals where needed. Its small footprint and plug-and-play design make it easy to deploy between a host computer and remote USB devices. Built-in power conditioning allows the remote unit to operate without an external power supply for most low-power devices, while compatibility with standard network cables ensures flexible installation options.

Suitable for

• Extending USB cameras and webcams to remote mounting locations
• Placing USB printers, scanners or peripherals farther from a host computer
• Extending keyboard and mouse connections in classrooms, meeting rooms or kiosks
• Connecting point-of-sale devices or other low-power USB peripherals at a distance

Key specifications

• Maximum extension distance: up to 45 metres using CAT5/CAT5e/CAT6/CAT6a cable
• Interfaces: USB (host and device connections) and RJ45 network cable link between units
• Power: bus-powered with internal DC power conditioning circuits
• Compliance: USB Specification 1.1 compatible
• Form factor: two-piece design (base unit and remote unit), compact and portable
• Color: black

How to use

Connect the base unit to the host computer’s USB port and the remote unit to the USB peripheral. Join the two units with a suitable CAT5/CAT5e/CAT6/CAT6a network cable (not included) using the RJ45 ports on each unit. Power is supplied via the host USB port; internal conditioning supplies the remote unit for most low-power devices. No drivers or software installation are required for standard USB operation. If a connected device requires more current than the bus can provide, follow the device manufacturer’s guidance and use an external power source as needed.

Usage recommendations

For reliable operation, use good-quality shielded or unshielded Ethernet cable appropriate to the installation environment and keep total cable runs within recommended lengths. Verify the power requirements of connected peripherals—high-power devices such as external hard drives, electronic whiteboards or multiple chained hubs may need external power or a powered USB hub. Ensure proper USB device compatibility with USB 1.1 if using legacy devices; modern USB 2.0/3.x devices may function but could be limited by the extender’s USB 1.1 compliance.
