I am sure you misread the label and it says 3 amps, not 30. Am I correct?
At 3 amps, it will work just fine when at a campground with the normal hookups available there, even with the AC unit running.
Now, boondocking, without hookups is a different matter, it would take too much power over too long a time to operate even with an inverter, if left running overnight.
However, there are 12 volt
oxygen generators which take less power, but I don't know their requirements or initial cost.
