It's not really the same thing. It doesn't check to see if each line is on a separate phase, they suggest you do that before use. If you trip one breaker you lose one phase, but not the other. This unit has relays inside that only pull in when plugged into two separate phases. You can hear the relays pulling in, one when the first plug is connected. If you connect the second plug to an outlet on the same phase, nothing else happens. When you plug it into the other phase the second relay pulls in and you get 220 on the out put. I haven't opened it to see how it's wired internally but I did try plugging both chords into the same phase to see what happened.
I'm not sure what the PFC would do if it lost one of the hot inputs. I know you can go 110 and neutral or 110 & 110 to get 220. I'm not sure if it would like 110 and an open, I don't intend to find out.
