This laptop carrying case comes in black, green, orange, and silver. It ships with an internal battery that charged my Dash in a bit less than four hours. But the Voltaic lost major points when it fried my phone as I tried to bypass the battery and charge directly from the panels, which, it turns out, deliver higher voltage than the battery. Note to Voltaic: Please idiot-proof future releases of this bag. The Voltaic was also finicky about sun - it stopped charging in both full sunlight and moderate shade.
