One might think that a solar briefcase was pretty self explanatory. It's a briefcase, with solar panels, however it is much more complex than that.
It has fancy speccs like being able to charge 3V, 6V, 9V and 12 V appliances. It also has things like, a protective shell to protect the solar panels, you know, the briefcase part.
You might also be thoroughly intrigued to know that it is a 13 watt solar charger and that it is being sold for $49.99. Yes, I know, the title solar briefcase did pretty much tell you all you needed to know.
