Devotec has developed what it calls the world’s first solar-powered wireless Bluetooth stereo speaker for portable sound and worry-free battery life. The unit includes a pair of 2-watt speakers, compact 16.5-by-5.5-by-5.5-centimeter dimensions that weigh half a pound.
The design includes a 150mA (milliamp) solar panel that illuminates yellow when charging. Devotec says you get eight hours of continuous play at medium volume and four hours at maximum volume.
