Camp setup opinions

First year and after hours of research I am only more confused

I've been playing with the idea of getting a solar generator, opposed to propane or gas, due to the Sun and cutting down on emissions/ cost. My idea was to get a generator only powerful enough to charge a couple phones and keep a small freezer running. Could fill the freezer with ice packs and rotate those out between coolers?

I am just curious if anyone else has done this or something similar? I am not sure where to begin, and would like to keep the price less than $500, is this idea even possible?
