I am considering a long ride this summer which will leave my outside for several days. I will be relying on a GPS as I will be in China. I need some way to keep the GPS working.
This brings me to the question, do those battery / solar cell combos, like the one pictured, actually work?
I intend to put it on the top of the stuff on my rear rack on a recumbent and use it on a GPS like this one.
