Had my Eco 160w panels hooked up to the Delta 2 mini the other day for a test run and got a high input of 151 watts and a steady input of 137 watts around midday, in Florida. Earlier, it was hazy and it was producing around 35 to 50 watts. I was impressed, although to be effective in an emergency I probably would need another set of panels to boost the input to closer to 300 watts, or get a stronger car charger. The good thing about the 160w panels is that they store easily and are not very heavy. They seem very well made.
