This is a good idea: instead of having a big ol’ battery pack on your iPhone, or carrying around a bulky charger or solar what-have-you, just replace your regular USB cord with this little guy. It’s got a cell built into the cord that charges while you charge your phone, and then you can use the cord/battery without a connection to give your phone a boost later on.
I think it’s great! Because I find I never need more than an extra hour or so (due to bad planning on my part usually), and that’s probably what a single cell like this would provide. They claim the X-power adds 4.5 hours, but that sounds a little fishy to me. Still, even if it only added an hour, it’d be worth it.
As if that wasn’t good enough, it comes in 6-inch, 20-inch, and 30-inch versions. We were just talking about how much we love short cables. It even comes as a retractable version! All this for $30, which is probably what Apple charges you for a regular cable. I hope they come out with something like this for standard mini-USB jacks.
