I flew Cathay Pacific late January and power banks were prohibited in both checked luggage and overhead bins. Of course the overhead bin restriction would have been difficult to police and enforce. Also prohibited to use them for charging devices or to be charged from the onboard USB outlets. But the onboard outlets were good enough for anything I needed to do during the 15+ hour flight.

In China (Mainland of course), they will toss your powerbank at security if it isn't approved, and the approval they are using is rather recent and Chinese specific, thankfully most recent powerbanks made in China have the approval. They are very efficient in snuffing out powerbanks also, their thoroughness would definitely make our TSA blush.

Only if those plugs are actually working....sigh.
