Last Saturday, I was in the airport waiting for boarding, a beautiful girl wa sitting beside catching my eyes. Oh, no no... don't don't make mistake, what I am interesting is a external battery pack connected to iPhone in her hands.

That iPhone external battery pack looks so nice, its surface is quite bright, just as the same performance as iPhone. I see the logo on the item is SPAMMER I checked it is a brand of Chinese iPhone accessories manufacturer.
It is too far to buy from China, is there anyone know where I can buy from amazon?
