Summary: These speakers are very compact and great for those on the go. I took them on a cruise and they worked great with both my video and nano ipods. The ONLY downside is that the unit does NOT charge the ipod. The unit has both battery and AC power sources but neither provide the ability to charge the ipod; however, this can be accomplished with a separate ipod charger that the unit does leave room for in the cradle. Other than that, a great purchase.
