*** IMPORTANT*** If you use a Brunton battery to charge an electronic device directly thru DC power from its output. You need to use a cord that you can control the voltage. Just Google : "Regulated Dc-Dc Universal Car Adaptor" and you should find what I'm talking about. An Example picture is below.
A lot of electronics will operate at voltages around 7V. The battery will only output 12V, which is TOO HIGH and may DESTROY your electronics.
Also, on any trip you should have a few extra fuses for the male cigarette lighter. The last thing you want is not to be able to charge anything because of a .50 cent fuse.
Shop around. Brunton isn't the only one making this stuff. Check out GoalZero and Powerenz!
Brunton Solaris 26 (1600mA) - will take 5-6hrs to charge battery in direct sun
Brunton Solaris 12 (800mA) - will take 12hrs to charge battery in direct sun

5D mark II w/Zeiss 28mm f2
GH2 w/Olympus Zuiko Digital 14-54mm f2.8 - 3.5
5D vs. GH2:
No color correction, both cameras were set to 6000K color temperature. I'm actually pretty surprised, I thought the 5D and GH2 wouldn't look anything alike but they seem to mesh just fine. My take so far: The 5D aliases more but the GH2 has more rolling shutter. Both give great results in the right hands.
