The WildCharge PowerDisc plugs into a gadget that doesn’t have a WildCharge “skin” available for it and lets it charge without plugging it into the wall. But it seems to make charging less convenient than the traditional method. I mean, you can either have a cable on your desk that you plug your Kindle into to charge, or you can have a big flat surface and then a dongle that you need to find whenever you charge it.
Until this is built into gadgets, like the Pre, I can’t imagine spending the money on it. [WildCharge via SlashGear]
