In 2007, Thanko released a bracelet battery that might not be that appealing for you. But this year, the company is again coming out with its wearable bracelet battery that looks identical to the previous model, but is now sporting the kind of style that will be perfect for a Batman costume.
This all-black bracelet comes in a thick wrist wrap that has a cable extension to connect to your mobile devices and charge them. New to this model is an adapter cable that will allow you to even pair this up with a greater number of mobile devices. It will also come with a 1,500mAh lithium-ion battery and an on/off switch.
