So I was trying to charge as fast as possible and multiple qc2 and 3 chargers were only slow charging. I assume this is due to the unisoc vs Qualcomm chipset. I was able to determine that pd chargers will quick charge at nearly 15 W. But only Samsung chargers with afc and one anker, with iq2 I think, will charge at non pd high speed charging
Use a known good Samsung 25w brick/cable to simplify troubleshooting... it's hard enough to begin with.
If battery start charge temp is <65F or >100F or has greater than a 75% charge on it, fast charging may be disabled. Display must be off.
Edit <oops>
I have an Rd tc-66 so I can see exactly what volt/amp/watt is being supplied. I used an anker, aukey, and several other chargers. Only the Samsung fast charger, the anker and any pd charger I tried were able to fast charge. I used 1 USB a to c cable for all chargers, so it worked on 2 qc chargers and not on 4 qc2 and qc3 chargers. For pd chargers, it was the same c to c cable, and all pd chargers provided 8-9v and 1.4-1.7a.
My quess, again, is that the unisoc chipset doesn't favor Qualcomm quick charge, so it's limited to Samsung afc and pd for high speed charging.

So once the disappointment of my spank new nexus 5x not being qualcomm quick charge 2.0 compatible (I found this out yesterday) after buying new chargers and batteries (portable charger thingamagigs) had subsided I was pleasantly surprised that many of my battery packs were actually charging at what the nexus 5x calls 'rapidly charging'.
So far I can report that these chargers tell me they are rapidly charging:
Aukey 54W 5 port qualcomm quick charge 2.0 wall charger says rapidly charging from both the qc qc 2.0 port and the other ones too.
Anker 2nd Gen astro 6400mah battery says rapidly charging
Anker 2nd Gen astro e5 16000mah battery says rapidly charging
Aukey 10000mah qcqc2.0 (pb-t1) doesn't seem to do anything? Doesn't charge it at all works on the original n5 (without qc obviously). But I find this very odd? I was wrong it does indeed report rapidly charging
How is everyone else getting on with your portable power?
My guess is even though you are getting the rapidly charging rating, you are likely getting 2a of the possible 3a max charging amps. It means a good handshake for fast charge is occuring even if the source of the charge is incapable of 3a.
Here is a good article explaining it: http://www.droid-life.com/2015/10/19/nexus-6p-nexus-5x-quick-charge/
I assume we should soon see actual 5v 3a charging devices come out to market.
I've replied on a different thread. You should use the app Ampere and compare numbers to the stock wall charger.
Sent from my Sprint Galaxy S5.
so this combo is working for me:
http://www.amazon.com/gp/product/B010UT6Z3Q?psc=1&redirect=true&ref_=oh_aui_detailpage_o08_s01
http://www.amazon.com/gp/product/B00W98IQ5M?psc=1&redirect=true&ref_=oh_aui_detailpage_o08_s00
the latter also allowed me to fastboot oem unlock.
so battery is at 59%, homescreen says 14 minutes till full.
cheers
can you please check with Ampere or GSAM for the charging speeds that you achieve?
does the device say fast/rapid charging?
Interested to hear the results from Ampere or GSAM as well
i cant get a good handle on how ampere works. it keeps measuring, takes forever, and fluctuates a lot.
with the aukey combo, i got 1830/2050mA @ 4.14v, at 53%, 37.7c
took it off charge for a while and tried again with the stock charger:
with the stock charger, i got 1850/1860mA(min/max) @ 4.159Vat 61%, 30.7c
I will try again at 50% today if I have time but I am pretty pleased with my little aukey combo. It was cheap.. I got it when there was a 7 dollar coupon floating around.
FYI, believe this is the same charger : http://www.amazon.com/gp/product/B00QEX83LA/

Yep that would be the one. charging at 1800mA is not the fastest that the phone can charge at though. I'm going to hold off for the ones that enable the full speed of charging

From the product description, you are only going to get 2A out of the charger. 5X doesn't do QC2.0, so you will only get the output at 5V, which for this charger is 2 amps.

But some Aukey chargers with AIPowertech like this one "charges all non-Quick ChargeTM 2.0 phones and tablets at their normal speed (up to 5 volts / 2.4A Max)with AIPower Tech Technology."
I've got the charger, just not the cables... so haven't been able to test.
I tested Aukey PA-T2 wall charger QC2.0 port ( orange one) on a Sony Xperia Z3 compact tablet
I recorded charging current up to 2.7Amp with the Aukey USB cable and up to 3.0 Amp with the Sony USB cable !!!! far more than the 2.0 Amp level current Aukey specifies......
The voltage - current output test show that the voltage stay in the 9.0V range with current up to 2.4Amp then fall down very quickly. It seems that the voltage stay at a value enough to deliver up to 3.0 Amp charging current to the tablet ....
Detailed test are here (http://78michel.unblog.fr/?p=860 in french....)
Current values where obtained from BMW recordings

LOL, thanks... but that doesn't really help this 5X cause. Given that there is no quick charge on the 5X, it'll remain at 5V. The question is whether it'll pull more than the 2A or 2.4A specified on these chargers at 5V on a 5X.

Aukey quick charge 2.0 behave like a standard charger when connected to a non QC2.0 compatible device. The output voltage will stay to 5V so the current level will be very sensitive to the quality of the USB cable and limited by the maximum current the device will afford.
In practice it is very difficult to reach 2A charging level ( even if the charger is able to deliver such current) with a voltage output of only 5V , due to losses in cables and connectors
From my experience the higher current charging level I obtained was with a Samsung wall charger refence EP-TA10EWE which deliver an output voltage of up to 5.5V at 1.9A ( nominal voltage is claimed at 5.3V)
I got 1.7Amp charging current on my Nexus 5 while with the Aukey QC2.0 the current was only 1.1 Amp in exactly same conditions ( these recorded data are also reported in my blog .....in French.....)

Thanks, didn't think to look at the link.
I wonder how older phones like the NA Galaxy S3 and Nexus 4 that both have QC1.0 ([email protected]) compare to the charging of the Nexus 5.
I'm curious as to how you did your testing, as I'm going to try my own testing once my cables come in. Did you drain all your phone's battery to 0 before performing each test? Phone airplane mode vs off? I also think that all tests must be done in relation to time, especially since the charging profile changes as the phone charges. I'm also curious as to how the non QC port on the Aukey performs, since it's spec'd at 2.4A @ 5V.

All tests are made with battery drained to zero before starting , and a complete charge is done in each conditions. That way I can check that the full charging time is logically related to the recorded current values. The current is recorded during the complete cycle at a frequency of one value per mn.
The air plane mode was off.
Aukey QC port and non QC port are slighly differents when connected to non QC2.0 devices :
QC port delivers 5.1V in open circuit, the voltage encrease to 5.2V at 2.2Amp, on the contrary the non QC port delivers 5.2V in open circuit and decrease to 5.1V at 2.2Amp. I did not test them at higher current level.
I did not tested Galxy S3 or Nexus4 , but I beleive that a charger like the Samsung EP-TA10EWE will deliver them the maximum charging current they are programmed to accept, as obeserved for the Nexus 5.
I got the same charging current curve I recorded with Nexus 5 and Samsung EP-TA10EWE, with other set of charger and cable. This means that this charging curve is defined by the Nexus 5 inner program , not the charger characteristics. The problem is that we never know which is the max current curve internally programmed for each smartphone...... so it could be a long way to find it.......
TurboPower charger that comes with it is the only thing that will give it a fast charge.
I have no idea how or why Quick Charge tech was left out.
Mine does indeed say "TurboPower Connected" and charges super-fast when I use the USB C Quick Charge 3.0 AUKEY Amp Type-C Dual-Port Wall Charger and the USB C Quick Charge 3.0 AUKEY Car Charger with Dual AiPower Ports. I can't seem to find it now, but I remember reading somewhere that the Moto Z does use QC 3.0, otherwise I wouldn't have bought the above products. NOTE: I am going USB-C to USB-C.
Does not use 3.0.
http://forum.xda-developers.com/z-force/help/moto-z-forces-turbopower-quickcharge-t3429607
In short QC 2.0 and 3.0 don't follow usb c spec according to a top Google engineer. According to Usb c spec the vbus voltage should not exceed 5v. QC tech exceeds this by using 9v and 12v to achieve more power. Motorola built the Moto Z according to spec which allows you to ramp up the current (amps) to achieve more power which is why our stock charger outputs at 5.7amps. You don't need QC to charge fast with Usb c. Usb c with power delivery is actually better . Either way the QC chargers put out 15 watts total. Our turbo charger does 28.5 watts using 5v at 5.7 amps and is actually faster than what's out now. QC chargers use higher voltage to achieve this at 9v 1.7 amps 15 watts, a charger doing 5v 3a does the same 15 watts. So to turbo charge your phone don't use QC chargers unless it also outputs at least 5v at 3a that's the key. Anything less than 3a won't turbo charge. It needs to be a usb C to usb C cable so the charger should have a usb C port not a usb a port like most of you are trying to use. No other charger out now does more than 3amps besides the turbo charger until then use chargers that do 5v 3a. Verizon has a fast charger that supports this and all other fast charging tech.

Will these charge as fast as the stock charger out of the box? And with a USB C cable does it need to support quick charge, or do all USB C cables support quick charge as long as you have it plugged into a USB C quick charge adapter like you linked to?
Nothing charges as fast as the stock charger as far as I know.
I looked around on Amazon to try to find a spare charger with the same speed as the OEM, but there are none as far as I know. QC actually goes against usb-c standard, so whoever has a phone that supports both is technically being shorted on charge speed. I will be waiting for the verified brands (ex. Anker/Aukey) to release a legitimate charger because there have been instances where wall chargers have completely destroyed devices. For the fastest charge, you'll want usb-c cables end to end, but since usb-c is not the standard yet, I would be very careful when buying lesser-known usb-c accessories. Z owners will have to wait for the market to catch up at this point.
Total side note but I wonder if the problems Samsung is having is because of their bastardized quick charge/type setup.
I'm happy we don't have QC.

The car charger that Verizon sells turbo charges the phone, but not as quickly as the stock home charger. I don't think any charger will charge as fast as the stock home charger, since it's optimized for the phone. But the Verizon USB-C charger charges the phone plenty fast.

I can confirm this. I just got this phone on an upgrade after insisting to the Verizon sales representative that I did NOT want a Galaxy S8, that I was absolutely sure I didn't want the S8, and that I think the Z Force is a much better device than the S8. After seeing the genuine shock on his face that I slighted his phone, I bought the OtterBox case and the Verizon branded USB-C car charger with it.
The car charger definitely charges faster than my non quick charge USB-C cable, but not as fast as the stock charger. The stock charger will take me from ~5% to full in an hour. The Verizon car charger takes about an hour and twenty minutes to go from ~5% to full.
All in all, it was worth the money spent on the charger. It is definitely better than the 8 hour charge my standard USB-C usually takes.
I have noticed that my stockpile of "fast" chargers I have acquired and used with my LG G8 do not enable the "charging rapidly" notification I get on the Pixel 5a.
Do I need to purchase a new set of USB-PD chargers for car & a/c outlet in order to achieve the fastest charging.

Probably. If your current chargers don't support PD then you won't charge at max speeds. And if your current chargers are using USB-a, meaning you need a USB-a to USB-c cable you're definitely not fast charging.
I can recommend Anker products. The Nano pro is a sweet tiny charger.
Anker's PowerIQ vs Quick Charge vs Power Delivery: What are the differences? - Dignited
With a lot of competiting charging standards, It's quite hard to choose what's best for your device. PowerIQ, Quick Charge and USB PD are the most popular choices today
www.dignited.com
I have anker products already however they are using the older type-A connection. its a shame that google will only allow rapid charging via USB-PD spec and not the older QC-QC3.0 spec.
anker car chargers that support PD are not cheap either but I guess I should future proof myself
Considering that the 5a is only capable of charging at a maximum of 18W (9Vx2A) I am pretty sure the USB-A to USB-C cable will work, if you can find a PD charger that uses USB-A. The reality is that you will probably need to buy a PD car charger, and a USB-C to USB-C cable. I'm in the same boat. There are quite a few options, with PD and QC and 2.1A/2.4A USB charging all in a single charger, on Amazon and the usual suspects. I think the real disappointment is that the 5a only charges at 18W. The upside is that the phone not only has a huge battery but it has adaptive charging so will slow charge overnight - fast charging being bad for battery life.
You should look for a USB-C "charging" cable. Charging cables have larger wires for lower loss in the cable, but also are often USB 2 speeds for data, which is fine for dedicated charging use. It is also possible to find USB 3 charging cables. There are a number of different USB-C cables out there, including special ones with an IC to support Thunderbolt. Be sure to mark the capability of each one you buy. It is a bit of a mess.
Quick Charge works well but is not strictly consistent with the USB spec (although it does not interfere with USB operation). IIRC QC uses analog voltage levels on the signal lines to control the supply voltage. IIUC PD uses a digital handshake. I for one have been happy with QC but am glad to move to PD for phone and eventually laptop and tablet. Recent announcements extend PD from today's 100W max up to 240W max.
Android 12 looks to have tweaked Pixel Adaptive Charging so phones reach 100% closer to alarm
Pixel users have had hit or miss experiences with Adaptive Charging, and Google now looks to have tweaked how it works on Android 12...
9to5google.com
this article explains a lot. I have been using adaptive charging for the "slow" overnight on my 2nd day of use since the battery has so much capacity. I woke up the other night because of a thunderstorm and noticed my phone was already at 100% 5 hours before my alarm was set to go off. Another night I woke up to use the bathroom, around 3 hours after I had went to sleep and plugged in phone, verified it said adaptive initially and now it said rapidly! Why would a phone switch to rapidly charging in the middle of the night. I might just dig out an OLD slow charger brick from the basement cave to prevent this overnight mystery from a gimmick feature.
Will post back when I acquire a car charger capable of "rapid" charging which 18w seems plenty fast to me for most road trips.

I actually have a car charger that triggers the 'Charging rapidly' notification. I would link to it at Amazon, but I bought over a year ago and it appears they no longer have that item in their stock. You need to make sure on those that they have a USB-C port on them labeled "PD3.0" or I believe that makes them incompatible. The search term I used there was
Code:
usb c car charger pd 3.0 21w
The 5a uses a USB-PD 2.0 charge protocol, not PD 3.0. Any USB-PD charger should work, as there were very few v1 devices ever made. When buying a car charger I recommend a charger with at least two ports: a PD charge port (USB-C) and a QC charge port (USB-A). The latest ones will support PD 2/3, PD 3 PPS, and QC 4 (and even 4+ and 5) on the USB-C port, and QC 2/3 plus several other protocols with the USB-A port. That pretty much covers the great majority of smart phones. I just bought a three port (2xUSB-C, 1xUSB-A) car charger. The USB-C ports are identical except that one is 30W (for phones) and the other is 100W (for laptops and tablets, or another phone). Note that increasingly new devices are requiring the PD 3.0 PPS, and there are fewer chargers available that support that. Also, higher power charging requires a special cable with a supporting IC inside so I ordered the package that included charger and cable.

A good 2 port car charger with 65W PD: https://www.aliexpress.com/item/1005002851748989.html
As has been stated, a USB-C Power Delivery compliant charger is required to charge at the maximum 18 watt rate.
Power Delivery is a USB-IF standard, whereas Quick Charge is a Qualcomm proprietary standard.
So I have a 45W charger, thinking about purchasing a 65W charger. I know The Tab S8 Plus only goes to 45W.
My question: are there any advantages to using an emark enabled cable?
I'm getting super fast charge notice with a 60W cable, no emark.
In my google searches, someone mentioned you can get "super fact charging 2.0" if you use an emark cable. Other pages said you only need emark above 60W. I found this comment on one site "... the Samsung Note 10+ or S20 Ultra which supports 45W fast charging. With these devices, the maximum electrical current is 4A, therefore it also requires a 5A cable with E-Mark. "
Does anyone know the ins and outs of this?
Thanks,
Joe
Get the recommended Samsung OEM brick and use the cable that comes with it. For the N10+ the 25w brick/cable fast charges fine and lasts for years if you don't roll up the cable.
Charging issues are hard to troubleshoot and non OEM bricks/cables only add to that burden.
At $20 a pop the 25w brick/cable is a no brainer.
So I have managed to answer my own question:
With a normal 3.1A US0b-C to USB-C cable, my 45W power supply is throttled back to 25W. It is reported as "Superfast Charge" mode by the tablet. Using Ampere, it reports that the battery is being charged at 5A at 4.2V --~ 21W
I bought a 100W E-Mark cable, and it now reports "Superfast Charge 2.0" -- and now Ampere reports it has bumped up to 7.5A at 4.36 V. So it is bumped up to 32W. Still not seeing 45W, though.
So it would seem to be charging 50% faster with the new cable.

I ues this combo for my s8+:
Anker PowerPort III 65W
Anker PowerLine III-Flow
It gives me 28W which is plenty fast for me. I can also use same charger for all of my devices, my laptop included
