Thanko Wristband Battery offers more compatibility options

The second iteration of the Thanko Wristband Battery goes one up on its predecessor as it no longer supports purely portable gaming consoles like the PSP and Nintendo DS, but will also support a whole range of new devices including all Japanese cellphones, iPod, iPhone, PSP, W-Zero3 Sharp MID and DS (all models). Not only that, you will benefit from an On/Off button as well as a 1,500mAh battery which ought to provide juice when you need it the most, especially during those unexpected moments. We’re not too sure what Nintendo has to say about their ad showing a DS running on a R4 cart though, perhaps it is a homebrew Thanko program?
