The Sphere confiscating non-restricted items this weekend violating point of sale?

I saw a show at The Sphere (Location: Las Vegas, Nevada) tonight and they forced folks at the door to dispose of both (1) portable power banks (think like to recharge your phone) and (2) USB cables. These items are not listed as prohibited in their website or on Ticketmaster at the point of sale. When I asked why this unadvertised policy was being implemented, I was told that it was because DEFCON is currently occurring.

My choice was to either throw away over $100 of electronics or miss the show. There was no option to check the items and retrieve them later and I was told that I could not change my ticket to tomorrow’s show in order to avoid losing my electronics.

The venue did not email ticket holders ahead of time to tell us about this random implementation. The signs around the venue showing banned items do not have power banks and USB cords on them.

Does this violate the POS? This seems incredibly wrong.
