The Powerstick is an amazing portable charger for mobile devices such as phones, iPods, iPads, digital cameras, GPS and MP3 Players. Simply recharge it from any USB port including computers and laptops and then use it to charge mobile devices. It aims to replace all of your chargers with one convenient power source. Weighing in at 40 grams (that seems light...) and with a footprint the size of a stick of Wrigley, this innovation can help eliminate the need for wall chargers all together. Plus, it comes with 2, 4 or 8GB of memory. Cool.
