Hoping someone could possible shed some light/offer an idea as to why this is happening...
I am using a 5 pack of Aukey USB 3.0 to C cables model CB-CMD2: (https://www.amazon.com/AUKEY-USB-C-Cable-Braided-3-3ft/dp/B01B634WNK), with varying lengths. These cables work fine with all of my other battery packs (non QC 2.0) that have USB 2.0 5v/2.1A out ports, with Aukey's very own QC 2.0 car charger that I use in my car, model CC-T1: (https://www.amazon.com/Dual-Port-Ch...dp/B00LJT2EPK?ie=UTF8&*Version*=1&*entries*=0 ) , and with the supplied QC 3.0 AC wall adapter that came with my HTC 10 phone. So the USB C cables appear to be fine. They just do not work with the Aukey QC 2.0 battery pack, model PB-T1: (https://www.amazon.com/Portable-Charger-10000mAh-External-Battery/dp/B00UBDI7EC), which is befuddling when it is Qualcomm QC 2.0 certified like their car charger I have that the cables work with. The battery pack still work fine with a USB 2.0 to micro USB cable to charge my old phone HTC M8, so the battery packs do seem to work, just not with the USB-C cables I bought, but those cables work with everything else really well, so I cannot tell who is at fault here...lol
I'm stumped....

Hi,
I bought PowerGen 3.1A Wall Charger, when I use with original Micro USB cable that come with my Samsung Galaxy S4, the charging current is 1.9A, when I use with a generic USB cable, the charging current is only 700mA. (I have a way to test the charging current)
Does anyone know which Micro USB cable that carry fast current, such as 1.9A like original USB Cable that come with S4, or even better, carry up to 3.1A that this Wall charger provides?
Thanks All.

Faster charging is enabled in the kernel, not by a cable bro.
Hi,
you have to look for custom kernel with fast charging support. I am using faux123 with fauxclock app.

I've been wondering this for awhile now, but never have found an answer. I know that when these phones are hooked up to a wall outlet with the included Samsung charger and cable that came in the box, that it will be charging at the faster USB 3.0 speeds. My question is... Will we still be getting TRUE USB 3.0 charging speeds when we have the included Samsung USB 3.0 cable hooked up to an adapter in the car via the cigarette lighter? Or do we have to purchase a separate USB 3.0 car charging adapter in order to achieve TRUE USB 3.0 charging speeds while charging in the car?
Thanks!

no you will get very slow speed unless its usb 3 if you get ,galaxy charging current lite on google play you will see
on main charger i get 1250
samsung car charger 650
usb 2 on pc 450
USB... Has no relevance when using a charging only port. Only the max amps of the port is important. I built my own charger with a 3a usb, I get the 1.2amps. Read the max amps of your car charger, on the back.
The Note 3 is the first phone to come with USB 3.0 support, the cable and connector are up to spec.
What I'm wondering if this helps with the charging speed, as the wall charger doesn't seem to be with a USB 3.0 connector.
Does anyone have any insight to this?

The wall charger has a 2Ah power output while a pc usb 3.0 port has a maximum output of 900mAh. If you use an USB 2.0 port it's only 500mAh.
The best way to recharge the Note 3 is to use the wall charger.

From a dedicated charger the final charging current is normally determined by the PHONE + CHARGER based on how the phone "recognizes" the charger as good/bad (and what battery level you already have + how warm the battery is) and how much power the charger can provide. I believe the max that I have seen on my Note 3 was 1800 mA (which worked with both USB3 cables but also with some good USB2 cables).
From a PC the charging current is the result of a more complex negotiation, the phone can still have "the last word" but it can not go over 500 mA on USB2 or 900 mA on USB3.
Somehow related - please note that on USB3 DATA you STILL need to MANUALLY enable USB3 mode EVERY TIME YOU PLUG TO THE PC. Even if enabled the mode will be reset to USB2 in 10 minutes and lost if you remove and plug-in again. That being said on my Thinkpad I have not seen it charging over 450 mA even when on USB3 under Win7 (but the speed difference exists, so USB3 is correctly triggered).
Also please note that the life of the battery can be heavily influenced by the charging current - the smaller the charging current the more cycles the battery will last on the very long term. Also high temperatures are pretty bad for the battery. So if you are in no hurry it is always better to charge with a small USB2 current that is guaranteed to not go over 500 mA.
Maybe I wasn't clear enough, I'm wondering if the wall charger is utilizing the USB 3.0 capability, and if there's any advantage of using the USB 3 cable over a regular micro USB cable.

No, there is not. The Note 3 has a USB 3.0 port, but it is only faster for data transfer. Charging is done at 2.0 speed, not 3.0. Regardless of what you attach it to, it charges just as fast as a 2.0 device.

What if you used a USB 2.0 cable with the 2Ah AC adapter? Would it still charge in "USB 3.0" mode and not give you a message to use a USB 3.0 cable?
I have my old 1Ah car charger and when I use a USB 2.0 cable, the phone says to use the USB 3.0 cable for faster charging.
But, looking at this pinout:
http://commons.wikimedia.org/wiki/File:USB_3.0_Micro_B_plug.PNG
It seems like only the USB 2.0 section is providing the power?
It's utterly confusing. Would be nice if someone who really knows this stuff explain how it works?

What's strange is that I have a car charger that is 1.0Ah. When I use a USB 2.0 cable, the phone tells me to use a USB 3.0 cable for faster charging.
When I use a USB 3.0 cable, the message does not appear.
But I'm thinking that the car charger can only put out 1.0Ah regardless of the cable that is used?
I suspect I know the answer to this, but I just wanted to get confirmation.
I was originally led to believe that the Galaxy S5's included USB 3.0 charging cable allows faster charging than a USB 2.0 cable. Upon thinking it over, the 3.0 cable should really only provide faster charging compared to USB 2.0, and only when plugged into a USB 3.0 computer port.
When using the same USB 3.0 cable via an AC wall adapter, the power output of the wall adapter should be the only thing that really determines the charging speed: Fast charging with a 2-amp wall adapter, slower charging with a 1-amp adapter; whether the cable is USB 2.0 or 3.0 should not matter.
Am I correct here?
The USB 3 cable provides only extra data lanes no extra charging speed. The AC charger will charge at 2amp and on PC you are likely to get not much better than 450mili Amp.
Wanted to ask before I consider returning the charger I got
I tested this car charger
https://www.amazon.com/gp/product/B01E764DXM
Using this
https://www.amazon.com/gp/product/B01MT8MC3N
Results were
Using USB A to USB C cable - screen off 8.98v/1A-1.67A(amps varied during the 100mA test I did) - phone read Fast Charging
Using a USB C to USB C cable plugged into the USB C port - screen off 5v/1.8A steady (zero fluctuation) - phone read Cable Charging
Now the charger says it is capable of 5v/3A output out of the USB C port but that's not what I'm getting to the S8, which makes me wonder if it's a limit placed by Samsung software to not go for higher Amperage (and therefore more wattage)
When I look at the estimated charging times, the QC (USB A- USB C) is usually 10 min faster than the USB C charging
9x1.67 is the max the phone supports, on 5v you might get 2a tops, looks like the usb-c port on that charger doesn't support 9v for some reason.
Has anyone found and tried USB-C cables that support high-power 5a and for sale in the USA? https://www.startech.com/ca/Cables/usb-c/usb-c-usb-3-1-cable-power-delivery~USB31C5C1M
