[Q] Will Transformer charge via USB 3.0 on mobo?

Hi,
Just as the title says, but does the transformer charge via the usb 3.0 ports on some modern motherboards?
Or will it only charge in sleep from those as well. I seem to remember reading that usb 3 had a larger power output, but I cant be sure.

It seems to get a little juice from my GA-EP45T-USB3P - but just a little bit.

It should charge at about the same speed as a USB port. The only reason ASUS uses a USB 3.0 cable is so that the AC adapter can deliver 15 (instead of the usual 5v USB) volts over the extra USB 3.0 pins. USB 3.0 ports can deliver 900mA (vs 500mA on 2.0 ports) but that is probably less than the discharge rate of the TF with the screen on.

USB 3.0 Charging

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:

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?

[Q] Does the USB 3.0 cable charge faster via AC?

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.

is a 5v 2.4A power supply enough for full speed fast charge?

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

Chargers for Fast/Rapid Chargers

Got a G7 coming in the mail. I have some requests as far as Qualcomm Quickcharge (QC), Motorola TurboPower, and USB-Power Delivery (USB-PD) so that I can get chargers/cables that work optimally for the G7 as well as my other devices.
I know the G7 comes with a TurboPower USB-C charger, which per the amazon description for the charger, supports 5.0V/3A, and also USB-PD 2.0.
https://www.amazon.com/Motorola-TurboPower-USB-C-Type-Charger/dp/B01M8MFCYQ
However, USB-PD should support multiple voltages and amperages for optimal charging, not just 5.0V/3.0A.
Can anyone with a USB-PD USB-C charger check out charging times/rapid charging mode with the G7 to see if the phone is USB-PD compliant (see if charge time is different than the stock charger)?
I have a QC 3.0 charger at home (will have to use a usb-a to usb-c cable) that I will be able to try and see if it gets rapid charging through it. I have read that the phones/chargers play nice with QC devices with quick charge times, but I doubt the phone is compatible with all of turbopower, USB-PD, and QC.

Well, got my phone today, and did some testing.
Charger that comes with the phone, turbocharger, is USB-A, and comes with an A to C cable. Lists 5V/3A, 9V/2A, and 12V/1.5A as outputs. Invokes "turbo charging" on the phone (expected).
Next I tried my Aukey power adapter with QC 3.0, with an USB-A port. This also invokes "turbo charging". This worked with both crossover A-C cables, and a micro usb cable with micro to usb-c adapter on it.
Next was the same Aukey adapter, but just a regular 5V/2.4A USB-A port. Just invoked regular "charging".
Next was my rav-power powerbank with usb-c 5V/3A port. This also invoked "turbocharging (15W).
Last, I tried a new charger I just received today for my work laptop - 65 watt USB-C adapter, I'm assuming with power delivery usb-pd (goes much higher than QC). Lower modes at 9V/2A and 5V/2A. This invoked "turbo charging".
Seems anything from 15-18 watts gets a "turbo charging" label. I find it amusing that is the "turbo power 15w" charging adapter but outs 18 watts...
In short - it seems that this phone does indeed recognize all 3 modes of fast charging - turbo power, QC, and USB-PD - or those standards are close enough to be somewhat interchangeable. Will do some timed testing later on.
Phone is same size as a galaxy s9 and is slick as hell - definitely buy a case asap.

I'll try to remember to check at work, I have an amp meeter that supports fast charge and see what voltage it goes to and amperage draw.

Seems to only do 5v charging so anything with a high amp rating is likely to turbo charge.
