Having to go through security again for a connecting flight, which I haven't needed to do before was a shock (should have probably checked in advance), but there wasn't really a clear rule on what external battery chargers were allowed through, some were confiscated even if they had the same capacity. Wasn't going to start a fight in China though so just accepted the loss at the time.

The airport itself was clean and modern.
