I know that normally devices are wired in parallel on AC mains, lights, power sockets. Even in multi-adapter power sockets, things are generally in parallel.
Is there any reason the following layout will not work?
Here, the PSU in each device would be a small 5 V/2 A switching PSU, and the devices may be something like an ESP8266. The PSUs I'm planning to use are happy with 100..240 Vac as input.
I understand that if one of the PSU's primary coils would fail, both devices will be affected, but what else here could go wrong or be a concern?
Does the fact that these devices are quite low power devices help?
