Constant traveling would mean lugging around not only your clothes and toiletries, but a heavy laptop (for most people anyways) as well as a plethora of chargers and adapters for the amount of gizmos you own. The Solar Backpack you see here aims to solve those woes by offering a convenient method of keeping your devices juiced without having to hunt high and low for a nearby power outlet. No idea on how efficient the solar panel is (it does look pretty small to me), but I do know the Solar Backpack comes with a variety of tips and connectors that cater to various devices. The output current stands at 200mA to 350mA, and it can withstand temperatures of up to 160 degrees Fahrenheit. You can now go green with the $48 Solar Backpack.
