Portable solar power company Goal Zero has launched the Rock Out 2 Solar Speaker, a “rugged and waterproof” portable speaker that is powered by the sun and features Bluetooth connectivity.

Goal Zero explains that the speaker was engineered for use without plugging the device in to charge. A solar panel powers the device throughout the day during use, and the company claims that a full 8-hour charge will last for over 20 hours of subsequent playing time. The device can also be charged via a built-in USB cable in two hours.

The speaker weighs one pound (454 g) and measures 7 x 3.75 x 2.5 in (17.8 x 9.5 x 6.4 cm). Multiple devices can also be daisy-chained together using the 3.5 mm female audio jack output cord. It features 2 x 40mm, 3W driver speakers and a 3W max, 70dB SNR, 100Hz-20kHz stereo amplifier. The device was launched at CES 2014 where it was named as an Innovations Award Honoree.

The Rock Out 2 Solar Speaker will be available from early summer 2014 (Northern Hemisphere) and will cost US$129.99.
