You don’t need me to tell you that solar chargers are quite awesome to have when you are spending time outdoors. They allow you to charge your gadgets with sunlight. This Clip-On Umbrella Solar Charger comes handy at the beach. In fact, it turns any beach umbrella into a solar charger. The solar panel is flexible and fold-able.
The developers claim this charger can fully charge an iPhone 4s in about 4 hours. The neat thing is you can attach this solar charger to tents, backpacks, and awnings. This exciting project is on Kickstarter right now.
