This rather odd looking Solar Light USB from Sanyo features a large solar panel to charge a fairly chunky battery. The battery takes around 15-30 daylight hours to fully charge up, giving 9 to 50 hours of light depending on which lights are used.
The light is perfect for rooms, emergency use and as a flashlight torch. You can control how many LED lights switch on, and therefore you can control the light output of the Eneloop Solar Light. There is also a bright LED that is typically used as a torch too. If you want to charge up any of your gadgets (phones, MP3 players, etc), there’s a USB socket that allows you to plug in your gadgets to charge them.
However, at 800g in weight and costing $267 USD, I get the impression that it’s probably too expensive and too heavy to be of use to most people.
