I've built a small batch of devices, which it turns out need isolated power. If I had known, I would have used isolated supplies. But they're already built and it's too late for that. So I'm looking for a small/cheap isolation transformer in an enclosed package that has a 120V input plug and output receptacle. Things like this are the closest I've found, but that's overkill and not exactly cheap. This "wall wart" device is more like what I had in mind, but instead of a receptacle it has screw terminals, which is not safe for 120V. If that wall wart had a receptacle on the back side, it would be perfect. Something like this could work if there were more room around the receptacle area.
Power requirements are low, about 80VA.
