Well, we all loved Regen’s Renu solar-powered iPod dock, but this guy pictured above towers over it. It’s called the Reverb and it’s 3-feet tall, living solely to crank out 60 watts of power using the power of the sun.
This bad boy will play your music for 4.5 hours at full volume or 12 hours at a normal volume. BUT, it takes 20 hours of outdoor sun exposure (or 40 hours indoor) to get a full charge. If you are not the patient type, the Reverb can be powered using a regular electrical socket.
