At least for my use cases, the included 4 m USB cable is not perfect, because it’s not flat to lead it through a window seal, and I couldn’t find any affordable outdoor USB power supply with USB socket.
So for my first installation, I put an indoor USB power supply with USB socket into a water-protected outdoor electric box.
But recently I found a very easy and affordable solution, an outdoor USB-C power supply from Amazon/Blink (Art. No. B0CBL64GYB, EAN 0840268909994).
Maybe that’s also interesting for other customers.
