Solar power testing 2016

I did some testing of solar panels and battery-banks, to charge smartphones and other USB-chargeable devices, back in 2014:

I have started another round of tests, this time focusing on ultra-light traveling, using a very small panel charging my smartphone directly, no intermediate battery-bank.

It's a work-in-progress, but good result so far:

I have posted about this to an Australian bushwalking forum:
