So annoyed at Krabi International airport

We have a power bank that traveled with us across the world and at Krabi International airport the security won't allow to take it back with us. Won't even let us put it in check in baggage. It's really stupid!! It traveled all the way here but can't leave here?!.  Also, no electronics and no jewelries allowed on checkin baggage. CRAZY! It's really annoying, I'm really annoyed with Krabi International airport security system. Krabi, Thailand.
