Narrative:

While boarding; a flight attendant brought a passenger's suitcase with a personal oxygen concentrator and a large battery. The agent was called; and the discussion was regarding the large battery in the suitcase. The agent called someone and said it was ok since it was labeled (non-spillable). Later; in cruise; the flight attendant brought up a page from their manual to read on personal oxygen concentrators. I also read our part one. The unit was not on the flight attendant list and no list is in our manual. She said she has used it several times on flts and recently from ZZZ to miami. Also she did not have a doctor's note. The flight attendant was going to notify the customer service agent at ZZZ2 because the passenger was continuing. The way in which it was stored to me was the main reason this wasn't caught. I also wonder how passenger are aware of the requirements for personal oxygen concentrators and who tells them. I know these are new items for the airlines also.
