If you're one to actually remove the battery from your cellphone quite regularly -- do you yearn for that second backup battery to have built-in charging capability from a standard USB port? Moxia may have your answer, as its newer USBCELL battery product can charge without the need to carry along that extra charger. Yeah, we prefer to use our laptop PCs to charge or phones instead of a small, plug-in charger, which seems to be, umm, really difficult. Well, not really, unless you despise small and portable chargers (and many of them in your bag.) Now, we like the idea of many travel-friendly gadgets being able to be charged by a single USB-type charger -- but when taken just for a phone, the point of this device becomes, well, moot.
