We had issues with this in the past, and honestly even when there are multiple plugs the contacts get loose inside over time and the charger will not stay connected. I ended up buying a travel charging block off
Amazon. It converts 1 plug into 6 plus 2 each of USB A/C. I usually bring one for the master and one for the living room for our kids to use. They dont take much space and I pack in a carry on to use in the airport if needed.
They have been a game changer.
We stayed in a newly renovated BWV 1 BR in SEP and half the plugs were already not working.
