Give your favorite student a backpack that can charge their iPhone, iPad or laptop while they commute. Voltaic’s most powerful backpack charger generates 30 minutes of laptop time after spending an hour soaking up the sun’s rays. The removable solar pocket can be attached to other bags, or placed anywhere in the sun to charge up. The onboard battery can also be plugged in on cloudy days.
