It’s a good test of my patience! There really aren’t any chargers out there that can charge 3 amps a slot so I just put up with it… and a little bitching along the way.
If I were to take a guess, it’s probably 25% of the time I have to unplug it and plug it back in at least once to get the charge rate I’m looking for. And those rates are at least 2A to 3A.
