Audio-Technica Boogie Box Battery-powered It produces sound, but it has scratches and dirt because it was used hard. It has great bass, which is nice. It might be a little heavy. However, I really liked it because it's a tough type. Since it's battery-powered, you'll be fine on trips if you have spare batteries. I haven't used it recently, so I'm putting it up for sale. I haven't done any maintenance. There's some rust, but I think it won't bother you if you clean it up.
