Can You Tell What It Is Yet?

I spotted this today and was very impressed as I didn't even know it existed - I thought it would be fun to see if you can guess what it is - post your answer in the comments below! If you know what it is and can provide some information such as links to where they can be bought that would be very helpful! Click the image to view a bigger version! If nobody has any ideas, then I'll post some clues.

Update: It's been correctly guessed - further details here!

It is a Solar Powered AA Battery Charger, it charges 4 batteries and says it will take 10-14 hours - although the time will depend on how much the batteries need charging, and how much sun light is available. They aren't as expensive as you might think - they are available for under £10/$12US - which is around the same price as normal electric battery chargers.

You can get them from the following places:
Ebay 4 AA Solar Power Battery Charger, Australia / Worldwide
Maplin - Charges all sizes of battery, £10, UK

If anyone knows of a US supplier or suppliers in other countries, please let me know.
