Battery constraints are the biggest hindrance to portable speakers, especially when they use power-sucking Bluetooth streaming. Devotec's Solar Sound Bluetooth Speakers should help oceanside podcast listeners, backyard music aficionados and tailgate dance partiers relax a little but harder.
Devotec says their speaker, which features dual 2W drivers, Bluetooth A2DP and AVRCP support, 3.5mm hard input, and an impressive, smartphone-sized 1500mAh battery, will last about 8 hours on a single charge—which takes four hours to attain by USB, and anywhere from 12-24 hours by sunlight—and could last longer if the battery is concurrently fed with the inbuilt solar panel.
$96 is fairly steep for this minuscule speaker, but it doesn't skimp on extras: it's controlled by means of a touch-sensitive button panel, and a built-in microphone lets the little brick act as an amplified speakerphone. Available now. [Geeky Gadgets]
