The problem with most built-in solar gadget chargers is that it just doesn’t make sense to stick your pricey phone in the sun for the whole day while you wait for it to charge. But the Regen ReNu modular solar panel takes care of that issue–the combination solar panel and battery pack attaches to the back of an iPod/iPhone dock or USB device for easy access to solar power. When you want to charge the panel, just remove it and place it near sunlight!
I heard somewhere about it… Cuz there are a number of devices or solar chargers that offer to charge gadgets with solar energy. It is simply not possible or viable for most people to allow their gadgets to be placed in direct sunlight for the entire day. That is where the ReNu Modular iPhone charger scores, it does not require the user to keep the iPhone in the sunlight all day long to charge it.
Once fully charged, this iPhone/ iPod dock can then be used for 7-8 hours of music. it is really great
