Hey guys,
If I use a 2 USB Type A male (1 for power from the Asus wall usb charger and the other for data from a computer) to a female Type A USB being plugged into the provided Asus Charge/sync cable, will it charge and sync at the same time or is the cable or hardware in the TF300T just not capable of doing both?
In case you are wondering, here's the cable we are using but instead of MIcro USB, its a female type A USB.
Thanks for your help.

Don't bother doing the split that way -- there's a much better way to do this, assuming you're on a desktop. The Asus Transformer tablets will go into rapid-charge mode even at 12V (max 15V) on what's typically the 5V line. So if you use the existing 12V rail from your main power supply and send it through the 5V line, the tablet will charge and communicate over USB at the same time.
Make sure you isolate the 5V lead, otherwise you'll risk blowing something up by feeding 12V back into your motherboard.
Does anyone have a confirmed working car charger for this phone?
My motorola car charger that I used for my GNex and GS3 isn't fully compatible with the G2. I get a message saying "slow charging" when I plug it in.
What do you guys use to achieve full charging speeds?
I realize there's a Q&A forum, but since this is directly related to accessories, I wasn't sure if it was better suited for this forum.
Nobody has a working car charger?
Both of these work for me.

the powerjolt is much more low profile though
That's just a generic list. The G2 requires a hi power charger

The powergen dual port works great. It has two 2.1amp USB ports, one that works with Android, and the other with Apple products (when using a data cable --> detecting USB vs AC charge mode). I have custom USB cables where I shorted the data pins so I always pull at AC charge rates regardless of the port type. In any event, this charger should provide you with the same capability as the OEM wall charger.
I have a 2amp car charger and it works fine, no message about slow charging.
the issue im runnin into is find a usb cable that enables fast charging
i have a dual usb car charger that put out 2amps per usb but cant.find an aftermarket usb to micro that can support more amps (fast chargin)
the oem lg g2 cable works...as well as the nexus 7 cable
i got this cable but doesnt charge more than 1amp

To short the data pins, I actually cut a USB cable, stripped back the insulator, re-soldered the +5V and ground wires, soldered together the data pins on the microUSB side of the cable, and stagger cut the data wires on the other side. Prior to the re-soldering, I slipped some shrink tubing on one end of the cable to re-insulate everything. Not for the faint of heart.
Background for those that don't know... Typically, Android phones look for little to no resistance on the data pins to detect a high current charger. Any other load triggers USB mode since most PC's are only designed to supply 500mA via USB. I assume this is a safety issue to prevent overdrawing a PC's port. Apple operates differently. They look for some nominal resistance as USB and switch to fast charge under open or some higher resistance. Most chargers >500mA are designed for the iPhone market unless they explicitly state other compatibility. Therefore, the data pins are floating. Any charger can be used at its max rating if you trick the Android phone with the homemade cable described above. Of course, then it becomes a power-only cable, useless for data. Clearly, OEM chargers for Android phones short the data pins internally so your OEM cable can be used with a wall charger (fast) or with your PC for data connections and nominal (slow) charging.
So the powergen mentioned above has two 2.1A ports, one labeled NA (non-apple) and A (apple) so you don't need to worry about mix-n-match devices and cables. Any USB cable will fast charge on the appropriate port. With my homemade cable above, my Galaxy Nexus will fast charge on either port.
Fast forward to the G2... Just got it yesterday and while in the car, I noticed my homemade cable only permitted SLOW charge on either port. Huh. Kinda a head scratcher. I ran in the house and got the OEM LG cable and both ports worked with FAST charge. So I tried one more thing, I grabbed a regular USB cable and observed the following: the phone went into FAST charge on the apple port and SLOW charge on the non-apple port. I can only assume that LG is detecting fast charge in a different way. The fact that a standard USB cable doesn't work with the data pins shorted at the charger but the OEM cable does makes me think there is something about LG's cable that allows it to pull max power from the charger. FYI, I plugged the OEM LG cable into a 850mA Motorola AC charger and it registered as SLOW charge.

I have pretty much the same thing, had a cable that would only do slow charge, so I stripped the wires back, and on the micro usb side I cut the green and white(data) and twisted them together. Now its fast charge no matter what charger I plug this cable into.... not sure why urs isn't....
My AT&T branded charger doesn't give me the slow charge notification.

Yes, but its not a 2 amp charger. We want a bigger fast charge vehicle charger...
I tried the USB plug in my car (Scion 2012) and two different Belkin cigarette/USB chargers today. The USB and one of the Belkins gave slow charging. The other Belkin did not -- worked fine. They were supposed to be identical, but I had suspected one was a fake. Guess I was right.
I just use the usb cable that came with their phone and plug it into my auto usb or the car's 110 outlet.

I've finally ordered my 6P but it does not come with a charger or usb cable.
1: Do I need a power supply that states 5v 3A or are the ones that states 2.4amp enough for full speed charging?
2: does the charger have to be a USB C socket? Or is it ok if it a standard size USB socket and I use a USB standard to USB C cable?
Thank you for your help
you need a 3A with a compatible cable for that amount of current
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
How does USB cable influences charge of speed? Why DASH speed charging works with the red USB cable provided by manufacturer, but not my other USB3 cables?
Does the cable have to be some some special kind, i.e. sort of certification or whatever? I would really like to use longer (i.e. 1.5 - 2 metres) cable from my charger, but all the cables I have and tried, plugged into official charger, does not support fast charge.
Thanks for answers!

That is mostly cause of a resistance between the wires which voltage drop indicates its a cable that meets the requirements. That is the common practice for such proprietary accessories.
Maybe someone has time to measure this and/or cut his original cable and find the resistor, I need mine
I'm sure it's that method.

You can buy a third party one cheaply from ali express. They work like the proprietary ones and there's also a 1.5m option. I personally haven't found any drops in charging speed at all.
Look in the USB-A side of the cable, there is an extra pin above the 4 normal USB pins which signals dash charging.

Yeah, that can be the reason!
