Which S7 Edge fast charger do I get for the car?

    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?

    Any fast charge 2.0 unit should work. You can even get fast charge 3.0 but there is no extra benefit over the 2.0 so you will be paying more for nothing.

    The S7 only supports Quick Charge 2.0, as you said.

    yeah i meant quick charge. you confused me with saying fast charging over and over in your first post.

    Samsung call it an "Adaptive Fast Charger".

    The output isn't much of an issue. Quick charge depends mostly on the battery from what I remember.

    But the S7 supports Quick Charge 2.0. Lots of car adapters listed that you can get.

    This is what I bought:

    Quick Charge 2.0 means you'll be charging faster via more volts pushing amps. It's 9v charging. But, that's in America. Regular has been 5v for the longest time. QC 3.0 is something like 11 or 12v. I dunno what's up with the description on that UK one. I can't tell if it's just all fraudulent, lol (never trust anything that says "GENUINE OEM" on it), or if it is because of our different power standards. Our vehicles run on 12v alternators. Is it the same over there?

    But, yeah, I bought one from Amazon.com and it's great. https://www.amazon.com/gp/product/B017JTEQKO/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1
    It's QC 2.0, not 3.0 at all. I had no use for QC 3.0, so saved a few bucks there. But, both ports can do QC 2.0, and both ports can put out a maximum of 2.4 amps to any phone that can take it. My last phone was an S5. At the most, it drew around 1.8 amps from the OEM wall charger. Yes, I have one of those little measuring things.

    Did you know, that, at least on the S4 and S5, not only obviously would we charge slower with the screen on using the battery, but the phone itself, cuts down on the amps coming in. I assume it's to protect the battery or lower heat. Both would immediately drop to 1.0a or 1.1a, or one of each, as soon as you powered the screen on.

    I've tested this S7 Active, but I'm not super familiar with these new charging standards of QC 2.0 using a 9v standard.

    I don't believe for one second that's truly an OEM Samsung car charger. I've done the same thing, bought legitimate batteries, "OEM", the real deal, 5 star reviews, for a Nokia E71. It looked almost 100% identical, EXCEPT "China" was spelled "CHAINA".

    They actually worked equal to the true OEM batteries.

    My point is, I have a USB charging meter. I don't know what it's even called, lol, but I've seen a few aftermarket brands of chargers and how they work. Samsung is THE BEST. You can't beat them. They tend to put .1 to .2 more amps out while charging. Even a charger like that would come with, say, the S4 or S5, it's rated output is 5v @ 2.1a, I believe. I hooked two phones up to it and was pulling around 5.3v @ 2.5 amps.

    A quality charger WILL have a higher actualy voltage output than rated. It's not harmful, it's a sign of quality.

    EDIT: I just thought of something. If you are not buying in America, well, hell, you don't even have a Qualcomm Snapdragon 820, do you? Quick Charge is a Qualcomm word. Exynos uses "Adaptive Fast Charging".

    Google the difference. Cause I sure can't tell. It's just a name game.

    What would you use in a 24v truck?

    I have a Griffin powerjolt and my s5 use to charge quick in the same truck. But my s7 edge using the same set up is really really slow and the phone gets really dangerously HOT

    AFAICT a Griffin Powerjolt is described as a "car charger", which means likely it's rated for 12V, and NOT 24V. Be very careful you don't over-voltage the thing. With a 24V to 12V step-down it might be OK.

    The vehicle I drive is 48V, I don't even attempt to try and charge my phone from it.

    48v wow. What you driving

    I don't even attempt to connect my phone to it.

    Do you mean 4v [emoji23]
  16. mikedt

    mikedt 你好

    Definitely 48V, that's what's in the instructions and stamped on the charger. 4V, I don't think would go anywhere....LOL.


    No Tesla of course, because I'm not in the United States. Although that probably has a 12V cigar lighter outlet.
