Can't remember how many years ago we purchased the Bose iPod dock, with two rechargeable batteries but it still sounds great. We play low volume also when we are in the mood, not looking to force others to put up with our music tastes. Sometimes good music can actually enhance my enjoyment of the moment and some campgrounds are so busy your hearing lots of man made noise anyway.
