Apple's External Battery Pack

An Apple patent application published yesterday describes a rechargeable external battery pack combined with a power adapter. The idea of the patent is to eliminate the need for a traveler to pack both.  But wait, there's more. The device would also have adapters that made it possible to charge your iphone or other portable electronic devices too.  

Why am I writing about this?  Because in the realm of portable electronics, one of the fastest paths to market for EESU technology would be the exact type of device Apple is seeking protection for with this application.    EEStor could create an external battery that wouldn't need to be customized for use by Apple, HP, Dell, etc etc.   

Note: Apple Insider broke this story. 

Note #2: No April Fool's Joke in this article.  Or is there?
