Sony recently rolled out its Portable USB Power Supply Adapter that was touted via Sony Europe’s site, although there was no further information on the device from various worldwide Sony sites. You get a modular design with one half functioning as a charger/AC adapter, while the other will boast a rechargeable Li-Ion battery and a USB port that is useful for keeping any USB-powered devices juiced up on your travels. There was no further information on the battery’s capacity or the number of devices that can be recharged, while we are left scratching our heads on just how much it costs as well. Too bad this isn’t solar-powered in some way, making it less than green for us.
