I'm only half kidding. I'm a bit of a prepper and I have lots of powerbanks and devices that charge from USB but besides idling my truck I really had no other way to charge any of them in case of a long-term power outage which seemed a bit of an oversight on my part.

Not like this solves the issue. 30 watts (under ideal conditions) isn't much but it's a start.

I don't think this is able to reach the full 30 watts either. Probably closer to 20 under ideal conditions.

The panels themselves aren't flexible - just the "hinges" between them. I don't think the portability makes much sense with larger panels than this. Better just go with a proper setup at that point.

Yeah I have 100 watt panels that make 70 or 80 most of the time; those ratings are for "ideal conditions" which I take to mean "perfectly aligned, in space."

As to the rigidity: It is a little flexible, compared to glass and aluminum. I bet it's perfectly serviceable at smaller sizes, but when it's 7 feet (2.13 Celsius) long:

the damn thing sags under its own weight. They shouldn't be made this big. Those glass panels together have the same rating and they actually work worth a damn.
