USB Extension Cable Buying Guide

Using USB cables is a popular way to charge electronic devices and transfer information. The main function of the cables is to connect devices to a computer or charging port, so the items packaged with devices are long enough to reach a machine that is nearby. USB extension cables are available for those that want to connect devices over a greater distance. Understanding the types of USB extension cable helps buyers to identify the compatible product that best suits their requirements.


Overview of USB Extension Cables

USB extension cables have an A and B end. The A end plugs into the source, such as a computer or charging port, and the B end plugs into the device. Some USB cables have two A ends that are interchangeable and both fit into standard USB ports.
