For those people heading to a festival this summer, a portable charger is a must-have gadget. Solar chargers are ideal because they allow you to harvest energy from the sun and then deliver it straight into your mobile device of choice without even laying eyes on a power socket. The Freeloader Classic has an internal battery which can be charged using either the detachable solar charging wings, or by plugging it in to a computer's USB port.
