Rukus outdoes itself by conceiving a more advanced solar-powered wireless boombox—one flaunting eight full range 22-watt speakers and a soundstage loud enough to amplify any outdoor venue. Get up to eight hours of audio playback on a full charge and let it bake in the sun for five hours to recharge. The XL also comes equipped with one-touch Bluetooth pairing, USB port for device charging, and a smartphone storage compartment. No other audio blaster with such ultra-modern features exists in the same price class.
