The mobile phone charger disguised as a rubber

This is an external power supply for your mobile phone that runs on just 2 standard batteries. This device is cleverly disguised as a rubber/eraser. It looks more appealing than those Chinese ones I posted a while back. It is quite small measuring only 7.6�2.5�1.5 cm. It is made by a Japanese company called Strap-Ya and works only with Softbank's FOMA phones. Too bad this is only available for Japan. I wouldn't mind having one of these for emergencies.
