This is a well designed solar charger that has had good reviews for its performance overall. It has useful suction pads so it can be fixed to the window in a bus or car and charge in the sun as you travel. For long trips the internal battery can be charged before you leave from a USB cable and then kept topped up by solar charging fairly efficiently. It isn’t designed to reach a full charge solely from solar charging, but certainly gets enough charge to power ipods and other devices. It has LED lights to indicate the remaining power level. An additional feature is its LED flash light / reading light. Altogether this is a slim design that is perfect for traveling.
