      As for you video. Basic math will tell you that trying to do what he showed will fry your shit.

      I agree that long term using the included power brick is probably a bad idea for the reasons you mentioned, the instructions, as shown in the video so specifically say, if you use a 12w brick, you can do 24V Passive POE on that port.

      FFS would you just stop already? Electricity is math not magic. Continuing to use a 12VAC power source will certainly fry your ER-X because of all the heat generated by the unit up converting a voltage level it is not designed to do. Using a higher watt supply does not change that fact.

      FFS yourself - the damned instructions say it can do this! Are you saying they have listed this as a specific allowable thing, and it's going to burn up because of an an upconvert issue?

      What instructions? it is not on their data sheet. And yes it will toast it.

      You don't think the SFP model is also doing upconvert, but just happens to come with a 12W+ power brick?

      No the SFP uses a 24VDC supply.

        Did you even watch the video - he showed Ubiquiti's own documentation stating that this was allowable using a not included 12W power brick.

          I watched the time you mentioned, and turned it off as stupid.

          Show me the document that supports it and then I will let you do it. But barring that, Ubiquiti's datasheet (linked above) does not list it as a choice.

              Great. Next time they should put it on the actual specifications instead of a footnote on a random graphic.

                LOL - this was pointed to very specifically in the video you so quickly dismissed. The video guy just decided to try his 6w power brick and got lucky... there was nearly just as much chance it wouldn't work... but he found the documentation that said it would before he even tried.

                  Now, how do I mark this as the answer? (I'm getting two.)
