Airport security is faster when your tech is in one place. Keep the organizer at the top of the carry-on so it comes out in one move.
Power banks stay with you
Lithium batteries belong in the cabin, never in checked luggage. The padded slot in the organizer is the right spot: protected, and easy to show when asked.
Leave the mesh pocket half empty
Boarding passes, a SIM tool for the destination, the hotel card: you'll pick up small things on the way. Give them somewhere to go before you leave.
