Etón Rukus Xtreme

The Etón Rukus Xtreme is a serious boombox that also happens to be powered by the sun. Featuring two full-range, bottom-heavy speakers that bring a lot of thump, the speaker also has a top-mounted, highly efficient solar panel to keep your music going all day. Come night, its internal lithium battery takes over. Made of rugged rubber, and water-resistant, this is a true go-anywhere Bluetooth speaker. [$230; etoncorp.com]
