This is the SOLIO CLASSIC2 Battery Pack + Solar Charger. Boasting twice the capacity of the previous CLASSIC model, a day of sun gives you three complete charges on your portable electronic devices. The CLASSIC2 now features a full-sized USB port allowing thousands of devices to easily connect, just by using their dedicated charging cable. The CLASSIC’s iconic design has been updated to be slimmer, while larger solar panels allow for faster solar charging. So what are you waiting for? Go green in style with the Solio CLASSIC2! Simply connect to the Classic using your device’s own USB charging cable. The fully charged Classic 2 will give most smartphones three complete charges. Charge the Classic 2 from the sun, on rainy days with a USB port, or the wall.
