Wouldn't it be nice if your home phone charger could double as a charging device itself when taken on the road? Yes, yes it would. Technocel undoubtedly agrees, as its PowerPak does just that. When plugged into a standard wall outlet, it can simultaneously charge whatever USB device is plugged into it (amongst others, considering the bundle of tips that are included) and juice up its internal cell; once unplugged, the integrated battery can provide enough power to a dead mobile to let you yap for around three hours, or just enough to make it through whatever sobfest your ill-willed SO has planned for you next week. It's expected to go on sale in around a fortnight at various retail locations and Sprint stores.Gallery:
