Most solar batteries that I have seen are smaller devices that are aimed at helping to keep your smartphone powered longer while you are on the go. There are lots of larger batteries out there for powering notebooks and netbooks, but most of them lack a solar panel for charging.
A new solar power battery has turned up that packs in 20,000mAh of power and includes 29 adapters to allow it to connect to all sorts of devices. The battery is offered from Chinavision for $148. You can charge the battery from the AC outlet.
It takes a full three hours to charge the device from an outlet and it you set the battery out in the sun in about ten hours it will charge fully. The adapters included with the battery are for smartphone, cameras, PDAs, notebooks and lots more stuff.
