Hey everyone. I am searching for a portable speaker for my ipad 2. What I need is one that is very portable, does not run on battery or have to be plugged in. But rather plugs into the 30 pin connector and uses power from that. So something small enough to fit in my pocket, whip it out plug it in and have louder sound and never have to worry about charging it, plugging it in, or changing batteries. it doesn't have to be top notch quality sound just loud. So any suggestions would be awesome. Thanks!
