Rock out under the sun with the Secur Solar Speaker System. This compact device features amplified stereo 3W speakers and a 2000 mAh internal battery that can power your smartphone as well as the speakers. The system is enclosed by a splashproof protective case with a 5.5V/70mA solar panel on top, which can charge the built-in battery in 25 to 30 hours depending on light conditions. The DC charging plug can be plugged into a computer's USB port with the included adapter and charge the battery in 4 to 6 hours.
The case zips open to reveal a convenient place to store your phone, as well as a DC charging plug, a 3.5mm stereo connector for playing music, and USB charging adapters for powering up your phone or charging the speaker. The case is shock-resistant and IP64 rated for dust- and splash-proofing. Three LED indicators display the battery level and the included carabiner lets you hang it from backpacks and more.
