Also that a Pi is a pretty light electrical load.  So it doesn't take much
power for it to start up.  It will depend on whatever USB power supply you
have, but it's possible it could work from perhaps 90v or lower, with a very
low AC current.  A regular PC might be a more substantial load and so not
start up, while the Pi might bounce up and down a few times as the AC
restarts, and as the AC flails about and eventually disconnects in the case of
a
grid fault (eg if the fault was power lines in the wind, a bouncing
circuit breaker, or something similar).
