The iPad and Nexus 7 are both great tablets. Their batteries won’t last you forever though. If you plan to spend some time on the road with your tablets, you need to make sure you have a way to charge them. The KudoSol case could help. It has a 5400mAh battery inside and a solar panel. You can charge your tablet using indoor or outdoor light. This case can serve as your phone charger too. The KudoSol is great for handsfree watching and typing. This project is being funded on Kickstarter.
