Check it out... sweet little gadget someone came up with at a rockstar price. I'm taking this little beast to Baja bit, if it works as advertised, this thing may just become a staple in my KJ.
13 watt briefcase solar setup with 4A charge regulator... Plus a 12V battery (14.5 amp hour with 80W Inverter and USB hookup)... you can charge the batt from the solar cell, 12V DC, or 110V AC.

I thought it was a pretty sweet for running campsite lights, external Ipod speakers, and charging stuff... Plus it was $150 shipped for the whole setup
