I bought one of these a few weeks ago and I cannot tell you how awesome it is.  I spend a lot of time in my Walmart taking pics and looking up things and my phone kept dying.  Now I just plug in this handy-dandy battery pack when my phone is low and I get about 80% of my battery life back in about 20 minutes.  Such a great deal!
