USB mini battery - power on the go : Shiny Shiny

It's a truth universally acknowledged that your gadgets will always run out of juice when you most need them to work. So MP3 players give up the ghost during long, boring plane journeys, cellphones die right when you need to make that important phone call and so on and so forth. Not any more, though! Brando's mini USB battery is... well, it's a miniature USB battery, innit? It works with mobile phones, MP3 players, digital cameras and other fun things, and will give them an instant energy boost, letting you keep on talking/playing/grooving on down long after the on-board battery dies. It's $36 and measures just 70x35x21mm, so it's small enough to stick in your pocket and forget about it until you need it.
