If you have purchased a powerful mains or car USB charger but find that it charges your device slowly or not at all when using a normal micro USB cable, this cable will most likely solve the problem. * Follows the "Dumb USB" specification" - get the full power from a computer USB socket, mains or car USB charger. Your device will not enter "data transfer" mode so there is no risk of data hacking / viruses when charging from an unknown USB socket. * PC USB sockets and many other chargers will only charge micro USB device at 0.5A with a normal data cable, this allows charging at 1A or more - twice as fast. * Uses 24AWG copper cable to allow faster charging than a normal micro USB cable - has lower resistance so more power goes to your device and less is lost in the cable as heat. 5ft long, 1 year guarantee. * PORTAPOW UK ARE THE ONLY GENUINE RETAILERS OF THIS ITEM. Other sellers such as "italk" will not be selling the correct spec cable.
