I would be surprised if the PW5 was any different than the PW4 in this respect, and I have not seen any reports of either overheating. Amazon marketing surely shows people using them in the sun routinely.

That said, they are black, which in direct sun, will convert that to heat. It can’t be entirely healthy for electronics. My phone will overheat if it is in direct sun for too long. As will I.

I use mine outdoors very rarely, and don’t use a cover, so cannot relate my own experience.
