The Eton Rukus line’s Rukus Xtreme and Rugged Rukus are outdoor, solar-powered, wireless music players. Both are topped with efficient solar panels which provide non-stop power to play music all day long without plugging in. But the fun doesn’t stop when the sun goes down. The internal lithium battery keeps music going for eight hours. Stream all your music from any Bluetooth enabled smartphone, tablet or computer and control your tunes from your device. Users also can charge their smart phone directly from Rugged Rukus by plugging it into the USB.
