If you're all about all that is solar for your gadgets, you might need something portable to keep your phone charged. Some of the larger panels work for cell phones too, but having a small charger with you at all times can be extremely convenient.
Although it isn't really meant to be used as a main charger, it would be great to get in an important phone call when your battery has died off. After 6-10 hours (depending on the weather) it will obtain a full charge which gives your phone an extra 25 minutes of life.
However, if you need it to charge a bit faster you can also plug it into an AC adapter, in which case it will take a mere 3 hours to charge. The cell phone charms will be released February 9th in Japan.
