PSP GadgetZ has taken some pictures of this interesting peripheral--quite possibly one of the cutest we've seen yet! Although this mini-PSP can't play games, browse the web, or play music, it can charge your PSP batteries. And that's all we want it to do.
Unfortunately, we've been unable to find a way to purchase this accessory. amazon.com carries a not-as-cute official Sony battery charger for a pricey $30.
