I was originally looking at the PowerSlider or Morphie Juice Pack but I don't really want to add bulk to my phone and the signal issues scare me away. I decided to go with a portable charger. I used to own the Power Monkey charger, but half the time it says its not compatible with my phone. Besides that, I love the thing. I did a search for results and there was a thread about this over a year ago, but most of those products aren't even available anymore. I know the IMAX Power charger, but I'd rather find something a little more inexpensive/smaller in size and I don't need something that will charge my phone 4 times. Maybe twice would be nice, but that's all that is really necessary. Also, since I would be traveling with this, something as small as possible would be nice. I'd like something that could fit in my pocket. Anybody have any suggestions?
