Make use of the cleanest form of energy Mother Nature has to offer to power your personal soundtrack. Using the sun’s rays, the Renogy E.TUNES Solar Speaker lets you take your music with you where you want to go. Compact and portable, it streams your music via Bluetooth or AUX cord and charges conveniently while you’re out using it. Don’t worry–your music will keep on playing after dark thanks to the 5000mAH lithium-ion battery that lasts up to four hours. E.TUNES also features an LED light and two USB ports to keep your other electronics charged, so you’ll have less to carry and more freedom to roam.
