npub1e7mmu5g4exntz8gcdwgclmhk8lqrg23zckzqwmzr3ahlc7mnx2cqqv7x48 (npub1e7m…7x48) The safe way is *really* having the grid voltage handled in a closed, isolated enclosure, and having a 5V cable come out of that. Anything else won't be importable into the EU, pretty much.

So, I'd argue "USB wall wart" is a) an extremely cheap, multi-sourcable, astonishingly resilient and reliable power source and b) "put your electronics into a case with USB connector somehow attached to it" is pretty much preferable to integrating it into the wall wart, for cost,
