Active USB 2.0 AB cable with built-in amplifier, 20m

This active USB cable is designed to connect external USB devices with USB 2.0 Type B connectors (e.g. scanners or printers) to a USB host (USB hub, USB wall socket, computer or laptop). Data transfer up to 0.48 Gbit/s. Thanks to the built-in amplifier, you will not have problems with transmission loss.

- Built-in amplifier for lossless signal transmission
- Compatible with Windows 2000, XP, VISTA, 7, 8, 10 & MAC
- No adapter required
- Plug and play

It is important to know

When purchasing a very long USB cable, like this 20-meter active cable with built-in amplifier, it's important to consider your needs in terms of range and intended use. While length can eliminate distance issues between devices, it also comes with some limitations that are often overlooked when reading basic specifications.

• The 20-meter length makes sense mainly for specific cases where a greater distance between the devices is actually necessary (e.g. connecting a printer in a larger office or at an event venue), but is usually not practical for normal home use.
• Since this is a USB 2.0 cable with its own amplifier, it is crucial to know that the intermediate amplifier is necessary primarily to ensure that the signal remains stable over such a long distance, but the USB 2.0 transmission standard limits the maximum data transfer speed compared to newer USB specifications.
• The cable has USB-A to USB-B connectors, which is typical mainly for connecting a computer to printers or some external devices, but is not suitable for direct connection to modern phones, tablets, or devices with USB-C or Lightning connectors.
• The length and active electronics mean that the cable is not convenient for mobile use or frequent carrying - the dimensions and specific purpose place it among stationary solutions.

In practice

🟢 Connecting a computer to a remote printer in a larger office

The cable is very suitable for situations where a stable connection over long distances needs to be ensured, for example in larger rooms or inter-floor connections.

🟡 Extension of the connection for an external USB device (e.g. scanner, external disk)

The cable allows data transfer over long distances, but due to the limitations of the USB 2.0 standard, it is not suitable for the high transfer speeds required by some modern devices.

🔴 Direct connection to a modern phone or tablet

Due to its USB-A to USB-B connectors, the cable is not usable for newer devices with USB-C or Lightning connectors without additional adapters.

Answers to frequently asked questions

Does the cable work with every USB printer with a USB-B connector?

The cable is designed for use with devices that have a USB-B connector, which includes most printers and some other peripherals.

Is this cable suitable for fast transfer of large amounts of data?

The cable allows data transfer up to USB 2.0 speeds (up to 0.48 Gbit/s), so it is not suitable if you need the higher speeds offered by newer USB standards.

Will the length of the cable affect the stability of the connection?

The cable has a built-in amplifier, which allows for a more stable signal over long distances, but there may still be speed or power limitations for very demanding devices.

Can I use the cable with a phone or modern laptop?

For use with modern devices with USB-C or Lightning connectors, appropriate adapters are required; the cable itself is not compatible without them.
