I have an official Samsung "Adaptive Fast Charging" plug for home (model EP-TA20UWE). On the plug itself, it shows: 9.0V @ 1.67A and 5.0V @ 2.0A. It works fine and my phone shows "Fast Charging" when it's connected to it. The equivalent official Samsung "Adaptive Fast Charging" for the car appears to be the ACADU10CBE but that only shows: Input: 5V 700mA / Output: 4.2V. Is this the correct product I need?
