Same here.. but you'll have a full charge before going to the airport. Then use the power bank to top up when you land?I think the problem for many people would be for those (admittedly like me) who binge social media while waiting in the lounge. You would be surprised how much battery instagram reels/tiktok uses and if you have background apps like Flighty running, which is constantly checking for new data, it adds to the battery drain.
With battery packs inevitably being banned, a USB port is essential in flight.
