17 Things You Should Always Do Before Boarding Your Flight

15. Charge Everything—and Bring a Backup Battery

The airport is no place to run out of battery—especially if your boarding pass, itinerary, and eSIM are all on your phone. Fully charge all devices the night before, and pack a portable power bank in your carry-on for backup. Don’t forget to bring the right cables and, if you're flying internationally, a universal power adapter. Many airport charging stations are either crowded, slow, or awkwardly placed, so your own setup ensures you won’t be tethered to a wall or fighting over outlets. Think of it as digital fuel—you’ll need it long before you hit the runway.
