This seems unlikely because all seats on the 77W have charging ports/power outlets. In addition, row 9 is at the front of the aft J-cabin. Row 18 is at the back of the aft J-cabin so, if he was just looking to charge, he should've picked a row closer to his coach seat. And he could've gotten away with it a lot longer in row 18 since it ended-up going out with 3 empty seats.
