I was very disappointed in this product. Went with it because it was official PS4 product and was the cheaper alternative than getting a double charger.
HOWEVER, I was so disappointed in this design and function. First of all, it is a USB charger... not a DC wall charger... so you either have to plug into your PS4 and use one of the outlets... when I could already do that with existing cord...or get a USB wall charger adaptor and use it that way! My opinion... that is just poorly thought out. Why purchase this if I'm going to plug into the PS4...just as I would with existing cord?
Secondly, the overall design is awful with moving parts and a separate charging adaptor to plug into the controller. Why make this so complicated just to charge the controller...AGAIN...when I could have just plugged into the PS4 directly?!? Then you have this charger adaptor you plug into the controller to then mount into the charger... that then depresses and moves down to charge? Huh? Again, maybe someone thought this was an interesting design, but I don't get it. Why have a separate adaptor piece that only fits this charger and that could be lost or damaged.... and then the rest of the goofy, moving contraption is useless!
Plus, no charging light on the unit either...a small thing I admit, but another annoyance.
In short, the only reason I didn't give it one star was because I think it actually was charging, but only after I went through multiple steps to set it up. Overall, a strange design and frustrating way to connect and actually charge a single controller, when I could just use the existing cord in the first place!
FYI... I immediately returned this as soon as possible and spent the extra money and got a double controller charger! Also, I'm a longtime PlayStation owner having had PS2, PS3 and previous chargers for those.
