Various solar panels are available in a variety of sizes that can also power or charge up electronic devices both large and small. But, here is one with little more special features that would surely impress you. The Brunton SolarRolls are such solar panels that are waterproof and flexible too - flexible in the sense that you can keep it folded.



The smallest is the SolarRoll 4.5 ($169), a 12′ x 22′ panel when it’s open. And it weighs 6.4 ounces and can output 4.5 watts, 15.4 Volts/300mA. That’s enough to charge small electronics such as cellphones and PDAs.



But if you require lots more power, here is the SolarRoll 14 ($399) which is a 12′x57′ solar panel when unrolled. It has a brilliant output of 4 watts and 15.4 volts/900 mA.
