I first ran into the fairly small SunJack 7W Solar Charger when hanging with the tech guys from CLN at a rodeo. Super impressed with the speed of charging. Just a few hours in the sun hanging on their backpack and it had enough power to charge up two iPhones. A great lifeline to getting battery power to any gadgets.
This is a must have when at a rodeo or outdoor event.
