Tokyo-based gadget maker Thanko is at it again. This time, the USB specialists are giving us the Wristband Battery, which is what it sounds like and supposed to make life easier for fans of portable gadgets.
To be more precise, Thanko says the wristband, which houses a 1500mAh lithium-ion battery, can be used for the PSP
, the Nintendo DS Lite (not the original DS), all iPods of the third generation or newer (not the iPhone), and a number of Japanese cell phones (buyers will get five different adapters). Thanko says their battery will power a DS (on the highest brightness setting) for up to 12 hours and a PSP for up to 4.5 hours.
