Gramo Speakers Are Solar Powered

We would love to see the efficiency of solar panels increase to a level where you don’t take longer to charge compared to using the device itself. The Gramo Speakers are a step in the right direction, and by harnessing the power of the sun, they are also wireless in nature – which means you run less risk of tripping over by accident with these around. The Gramo Speakers is extremely flexible as it plays nice with a wide array of devices, ranging from notebooks to a portable media player. Just in case you listen to most of your music at night, there is always the internal battery pack that can store energy converted during the day. These speakers also have the added advantage of being folded completely to be flat enough to carry around in a pocket.
