Tap into the sun's power on the go. PEARL offer a solar panel that weighs less than 1 kg and is about the size of a book when it is folded together - but is supposedly able to deliver 28 watts when folded open. You are supposed to be able to attach it to your backpack or bike or use it while you are camping, in order to use the sun's energy to charge your phone or power bank.
