USB Cell - rechargeable batteries for life
Every year 15 billion alkaline batteries are thrown away. Rechargeable batteries are clearly better as they create needless waste but also usually need distinctly unportable chargers. That's where USB Cells come in. As you can guess from the name, you flip open the top of these rechargeable AA batteries and plug in to your PC or laptops USB port and then use with whichever battery-operated device you like. They're now available in a range of pastel colours for the fashion conscious - £10.99 per pair/ US$19.95
