One minor travel annoyance I’ve regularly encountered is that airplane outlets don’t hold U.S.-style power plugs (types A/B) snugly. My devices come unplugged frequently during a flight.
While taking a couple trips to Europe this past year, I noticed that airplane outlets are international and found that type C/E/F plugs (used in a number of European countries and beyond) fit more snugly and hold for the entire flight.
