I am using the plug more than satisfied. Purchase was crucial for me first of all to the compact design. It bothers me just somewhere if so protrudes from the center console of the car a huge charging adapter, which makes almost impossible a meaningful use of the underlying shelf. This part is so small that it almost disappears completely in the can. But do not worry: It can also be easily found again; a small edge is about, and that's enough fully. Loading a iPhone 6 is really fast. Not surprising at an output of 2100 mA. And yes, each of the two ports provides 2100mA, bringing two iPhones, two iPads or whatever can be loaded with undiminished speed. I use the machine mostly to power the phone while using a navigation software with current and possibly also the one or the other gadget (Bluetooth headset, etc.) charge; but was already one or the other passenger delighted still to find a connection for his cell phone. Unlike previously used by me charging adapters with lower power the mobile phone is the way also WHILE navigating quite loaded quickly. In some other plug I used to be happy if I despite power supply after driving at least still had the same charge level as before. I can recommend the plug fully, have him now for several months in use and would buy it again immediately.
