This generous cable lets you put a little extra room between your Kindle or other e-reader and its charger. So you can use your reader while it"s charging, without being tethered to the wall. This cable"s got a micro-USB connector at one end, for your reader; and a Type A standard USB plug at the other end, for connecting to USB chargers or the USB port of your computer. And a full 3 meters (that"s about 9.84 feet) of freedom in between.
