AC Powered USB Hub

Tired of reaching through the back portion of your computer just to use your flash drive or other USB devices? Worry no more, the AC Powered USB hub will solve that problem. This cool device acts like an extension port for your computer, which normally has limited ports available(2 ports on the front and 2 ports on the back as well). This gadget will make life more easier for users that uses different kinds of USB devices.

A self-powered USB hub can be used to connect digital cameras, card readers, keyboards, mice, mp3players, memory sticks and many other handheld USB devices. For more robust components such as external drives, printers, scanners or fax machines, an AC-powered USB hub is a better choice. Some of the AC-powered hubs come with an AC-adapter, while others have the capability, but require the separate purchase of an adapter. When shopping for a USB hub, be sure to get one that will best meet your needs.

Another feature to look for is 1.1 or 2.0 compliancy. This refers to the two versions of USB technology. USB 1.1 is capable of data transfer speeds up to 12 megabits per second (mbps), while USB 2.0 can transfer data at 480 mbps, 40x faster. Initial USB devices were engineered to use USB 1.1, while later devices took advantage of the newer 2.0 compliancy.

An AC Powered USB hub is an inexpensive, handy addition to any system, especially useful with laptops that normally have too few native USB ports and older systems that have rear ports. An AC Powered USB hub can be purchased in a four-port model, a seven-port model, or greater. Multiple hubs can be used for scalable growth.
