We’ve introduced some cases with external batteries for iPhone and iPhone 4. But ienergy PadPower is just the second iPad case integrated external battery that we’ve ever seen.
PadPower iPad case is designed by SolidMicro, a Japanese peripheral manufacturer. Similar with many battery-integrated cases, a rechargeable battery has been integrated in the backing of the iPad case. Its capacity is 6000mAh. This mean the case can double the use time of the iPad. The backing LED indicator can tell you the status of the integrated battery pack. Apart from that, the case comes with a USB cable to charge the iPad case or sync the iPad with iTunes. Of course, the iPad case can also prevent your iPad from dirt, scratches and bumps.
SolidMicro ienergy PadPower is priced at 12,800 yen (about $158 USD). SolidMicro has started accepting the preorders of the iPad case at present. If you want one, you have to contact a Japanese gadgets exporter such as Rinkya or wait patiently for it to appear in Japanese gadgets online stores such as GeekStuff4U.
