The Wristband Battery 2 is a USB 2.0 bracelet that can recharge your iPhone 5, laptop, gaming device, or other mobile toy on the go.

Unless you're into Borg-chic accessories, it's extremely unfashionable. But it comes with eight types of connectors including Lightning, dock, PSP, and various Japanese phone jacks.

The shackle has a simple metal clasp, weighs some 2.8 ounces, and comes with a 31-inch stretch USB cable.

It has a LED display showing the power reserve, as well as recharge button. Its lithium ion battery pack takes about four hours to charge and can power a Nintendo DS Lite, for instance, for about 7 to 28 hours depending on brightness settings.

Thanko is selling the Wristband Battery 2 for 1,980 yen ($20). There's no English page for it yet, probably due to the Obon summer holiday in Japan, but it will probably appear on Thanko's international site here.
