A:Answer Yes, I did that a few times but not sure if you want to leave it plugged in all of the time. While the batteries was being charged, I was able to charge only one phone not 2 or 3, also wasn’t able to charge iPad Pro when it was plugged in and still charging itself. But you might be able to do those things if it had full battery and you are just leaving it plugged in....but plugged in all of the time might not be good for the batteries.
