I bought the iCharge ALL specifically for use on a road trip, where I would be taking a lot of pictures and didn't want to be troubled with having to find an outlet at every coffee shop or restaurant I patronized to get my power fix.
While the iCharge certainly is portable, it doesn't just firmly snap onto your phone. I was hoping that I could click it into place, throw it in my bag, and my phone would magically charge while I was out and about. I found that the connection to the phone port isn't that stable, and you have to figure out a way to prop up the device so that it doesn't disconnect from your phone. I was on the fence between ordering this device and another that gives only 1/2 a charge. Given the inconvenience of the iCharge ALL's poor design, I would have ordered the other option.
