Minty Boost: Portable USB power
Posted by admin on February 3rd, 2010
This project details a small & simple, but very powerful USB charger for your mp3 player, camera, cell phone, and any other gadget you can plug into a USB port to charge! The charger circuitry and 2 AA batteries fit into an Altoids gum tin, and will run your iPod for hours: 2.5x more than you’d get from a 9V USB charger! You can use rechargable batteries too. [via]
