I already have an adaptor for my Philips Vibe player, but needed another for recharging my wife's electronic cigarette, so bought with additional short length USB leads (from Amazon, of course). It works, so will also now be part of our holiday kit. In addition, because of the present heat wave (July 2014), just bought a USB fan that has a 1amp current demand and it runs that perfectly without overheating, as well.
