While this RDP has great sound, the I Phone charger/player did not work. It did work fine with the aux cord, but that kind of defeats the purpose. The electrical charge lasts a long time, and overall am happy with the device.

I had a Bose sound-dock before, and it dies! So my choice was to spend more money for less feature to stick with Bose. Sony always made good product. My wife wanted to be able to listen radio and this sound-dock was able to do it. The battery last a few hours and I just love the fact you can put anything with a mini-jack like your laptop or any kind of other device NOT only an Ipod, and have a great sound. About the sound, which is my job (sound engineer), there is plenty of power, the low end is warm enough, and crispy in the high end. So if you want something you can take with you, even when you don't have power, and looking for some quality this one is for you, you won't be disappointed.
