This is an outstanding charger. I have had no problem with this as of 3 months of daily use. It usually takes around 6 hours for a full charge.
It works as it should and some other chargers can't even do that. This is one of the best chargers I have used.
It doesn't even get warm while it's charging.
I think this is one of the best Dualshock 4 Base Chargers I've seen as of yet.
