The hard coated finish on the solar panels appear to provide a level of ruggedness and protection that I haven’t seen on other portable panels

like about other portable solar panels is that when the power generation discontinues for whatever reason (eg, low or no sunlight), you must reset the unit you are charging when the sun returns.

We saw lots of cheaper solar panels but none that have the power storage built into it.

There are combinations of portable solar panels with external power banks that are cheaper
