Solartab is a premium solar charger for smartphones and tablets. Solartab relies on the sun to charge, and even features a second internal battery that stores solar power for charging when the sun is hiding behind clouds or has gone to sleep for the day. The Solartab has a unique built-in cover that protects it when it’s tucked in your bag. But also works as a stand for the solar panel, so you can angle the panel in three different positions, for the right angle for maximum exposure to sunlight.
