Thinking of purchasing a Solar Charger and battery pack, and am looking for suggestions or 1st hand feedback. I was originally looking at the Goal Zero Nomad 7 solar panel with with there guide 10 re charger. The battery pack looks to have good reviews but most of the reviews I have seen on the solar panel say that it does not auto switch back on if the charge in interrupted and does not charge very well when it is overcast. So now I am thinking of getting a different solar panel from Suntactics because the reviews say it performs better in lower light conditions. Thanks
