You’ve seen them, people sitting on the floor, crowded around those rare power outlets at the airport. Everybody trying to charge their devices before they board the plane for that long flight. Perhaps you’ve tried carrying around those big, bulky extended batteries so you could get a little extra battery time. Now it won’t be a problem. Delta Airlines has installed USB ports on every seat on every long haul international flight so you can charge your device and stay powered up right from your seat.
