I'm still loving using my iphone and having the organizer functions of my Tungsten C. I'm also still finding the USB Fever iPhone portable power station very handy and here is one of those examples. One night last week I didnt charge my iPhone properly, the USB cable was pluged into the device but not into the power socket. The following day was going to be a long one and I wondered why I only had 60 percent battery charge, it was then when I noticed that I hadn't charged it properly. So that day I went about using the portable power station which provided me with sufficent power for the day and to he fair I was pretty pleased of the fact that I had the back up because I don't think I would have lasted the day otherwise so I can honestly say it came in handy.
