Works as it should. Gave a half star off because it is not retractable. Otherwise it's a very good charger.
I like these USB cable that have multiple ends to charge different devices. I can now charge my S7 and my iPad Air 2 at the same time.
The only thing I wish they would have done was made the logos on the Lightning, Micro USB, and USB-C different so I can distinguish them at night.
Also if they could have made the 3 cable a bit longer so when you are charging multiple devices they wouldn't have to be almost on top of each other.
I didn't know if it was a single device at a time. But i was surprised to find out it was fast charge and it supports all 3 devices at one!
