It works flawlessly and charges the device in the same time as Samsung's fast wall charger (0-100% in 1 hour and 39 minutes). The only downside is that, although it is large in volume, it only has one charging port.

I believe that genuine accessories of any device are the best thing you can buy in order to be served well!

The Note 4 takes 7-8 minutes to increase 1 unit for me, while the S3 takes about 1.5 minutes for each unit. I expected much more from the so-called fast charging.
