Does the V20 support USB-PD charging? - LG V20 Questions & Answers

tl;dr version-
I tried charging my V20 from my Nintendo Switch charger, and it didn't just "not work..." it tripped the charger such that I had to unplug it briefly before it would charge anything again (even the Switch). Does this mean the V20 doesn't support USB-PD? Or is the Switch charger just supplying the wrong voltage/current combo for any device other than a Switch?
"I've got time" version-
The simple act of charging your phone has gotten overly complicated in the last generation or two of phones... with branches of QuickCharge (2, 3, etc), and USB-PD (Power delivery). Not to mention all of the sub-par cables out there, which mandates a separate search on the Benson-Approved list.
When I bought my US996 (unlocked) V20, which officially supports QC3.0... I stuck with all of my existing QC2.0 chargers that I had from my Note 4, and I bought a couple "good" USB-C cables in order to charge the phone in the car, at work, etc.
Now I have a need to buy more chargers and cables... as well as a powerbank for an upcoming trip to Disneyworld. So, I'm curious what methods I can employ to charge my V20. I have the opportunity to buy USB-PD chargers and powerbanks, as well as cables that are USB-C on both ends to use with those USB-PD devices, but I'm not sure if it will fry my V20, or at least not charge it efficiently/at all. I came to realize that there are some politics involved with what charging schemes certain hardware can support, what they're allowed to SAY it supports, advertising, etc. I even saw an article that the LG G5 (or maybe the G6? I forget) supports USB-PD, even though it's not advertised... so I thought the V20 might be the same. So I tried it...
I recently purchased a Nintendo Switch, which is a USB-PD device, so I (foolishly) tried to charge my V20 using the Switch's power adapter. It caused no damage to any device, but when I did plug it in, the phone briefly said it was charging, then NOT charging... and the power adapter wouldn't charge ANYTHING again until I unplugged it from the wall for a bit and plugged it back in.
I take this to mean that my V20 does not support USB-PD... but it may also be that the Switch power adapter is a specialized device that supplies a voltage and current combination that is ideal for the Switch, but my V20 finds to be offensive. The Switch power adapter is not intended to be "universal" in any way, so my short test only eliminated the Switch charging adapter as compatible... not USB-PD as a whole. If it would have worked, my experiment would have validated USB-PD as a charging option.
Can anyone comment on this? Thanks!

I've been using my V20 with the following USB-PD charger successfully:

I've been experiencing much faster charging than with my other QualComm QC 2.0 adapter.

Sorry for the late reply...
Very interesting. So, you're using that power adapter with a dual-ended USB type C cable? Using an app like Ampere or AccuBattery... can you tell me what kinds of current flow you get with the screen off and on? If it's significantly more than 2000mA, I'd be very interested.

I use a Pixel charger, which is PD. It has a wall wart and a 6' USB-C to USB-C cable.

I got mine at Best Buy for $25 CAD.
It charges my V20 quicker than either of my QC 2.0 or 3.0 chargers.

Moto Z Force's TurboPower™: QuickCharge or USB-PD?

Does the Moto Z Force follow Qualcomm's Quick Charge standard or the USB-PD standard? I ask this because the TurboPower™ 15 charger outputs multiple voltages like QC standard; but the TurboPower™ 30 that comes with the Moto Z Force outputs only at 5V at a reasonably high available amperage of 5.7A, which look more like the USB-PD standard.
Additionally: which (if any other than OEM) wall and vehicle chargers available will optimally rapid/quick/turbo charge the Moto Z Force?
Thanks.

I can tell you this. I have a QuickCharge 3.0 charger at home (USB charging hub) that will not engage TurboCharging on either my Moto Z or my Z Force. However my Nexus 6p charger engages TurboCharging on both phones. Odd... I am going to try a different USB-c cable tonight to see if it does anything on that 3.0 charging hub.

Looks like the Moto Z force does not follow QC 3.0 standards. The reason the Nexus 6p charger is working is because it outputs 5V and a 3A current which is Turbo charging as far as Moto is concerned. I think our phones follow the USB PD standard. Reason being is the turbo 30 charger outputs 5V at 5.7amps. that's a lot of current but the voltage stays at 5v. Usb pd can get up to 20v at 5amps for a max off 100w. Quick charging is different in that it ramps up the voltage to 9v or 12 v depending but usually keeps current at 2a and below. USB PD tends to keep voltage low but ramp up the current draw. Quick charge will usually not see more than 3a on most chargers. If it does see 3a our phone will more than likely register as turbo charging. If not we get the standard 5v 2a charging. Bottom line is QC maxes out at 18w I believe. Our phones charge at 28w if you multiply 5v by 5.7a u get 28.5watts. This currently beats QC 3.0 devices which are all mostly 15w chargers hence why the Moto Z has the fastest charging out now. To increase power you either have to up the voltage or the current in amps. Different standards but achieve a similar goal.
I've tried all my QC 2.0 and 3.0 charging devices. Nothing will charge it fast unless it's the TurboPower provided by Moto. That pisses me off so very much.
I dont think these devices (nor the new Nexus phones) use QC or USB-PD. I think they all use something called USB-c fast charging. I returned my QC 3.0 charger and have another one on the way that claims to be USB-c fast charging. Ill report when I have it in 2 days.
If you notice the chargers for the Nexus and Moto Z phones are different than most chargers. The Moto phones have a non removable USB cable and the Nexus has a USB-c connector on both ends.
What I think we are looking for, and what I have on order, is a charger that has a USB-c input on it. I have a charging block that claims to have USB-c fast charging on its USB-c input. The charger I just returned that had QC 3.0 on it also had a USB-c input, but fast charging was not enabled on it. The new one claims to be.
So long story short you need to use a cable with the small C connector on both ends and a charger that has a USB-c port with fast charging enabled on it.

I also tested a Anker QC 3.0 wall charger and in half hour it only charged about 20%. Not quick or turbo speeds...
Very bummed. I just bought a QC 3.0 battery, car charger, and wall charger and threw away the boxes. I guess I can give them to my wife who has a LG G5...
I hope that eventually there are batteries and car charges that will charge this phone quickly. QC 2.0 was a feature that I very much liked on my last Phone (Droid Turbo). Being able to charge at those speeds was very nice on the road or with a battery.
The only other things is I believe our phones are equipped with usb 3.1 standard. I believe this standard allows for up to 20v of power at a max of around 5a. But any charger that does 5v at at least 3a will pit our phone into turbo charging. I have a Verizon branded fast charger that does 5v/3a and it recognizes it as turbo charging and actually does very good. Not as fast as the stock charger but damn close. Motorola stated they follow the USB C standard for charging which is 5v 3a. So i still say it's a form of usb PD that Motorola is basing there technology off of because the amps our stock charger is putting out is 5.7 amps. The usb c standard stops at 3a without usb 3.1 which we have on our phones and usb pd to up the amps. I would love to see you report back with the findings on the new charger!!!
We'll all know soon. I will even tell you the amps it puts out vs the stock charger. I have a way to monitor.
To save y'all time. Look for chargers that output 5v at 3a. These will turbo charge your phone. Just like the Nexus 6p and Nexus 5x our phones do not follow Qualcomm quick charge standards. So those accessories will do nothing for you because QC doesn't put out past 2a. QC does 9v at 1.67a. multiply that and you get 15watts. Same thing as a charger with 5v and 3a. Multiply that and you also get 15w. Different ways of doing it but same end result. Verizon has a wall charger and a car charger that outputs at 5v 3a. It is also Qualcomm quick charge ready for other phones you may have. It also states on the side of the box that it is USB power delivery 2.0 compatible which I think is why it fast charges our phones. You're welcome
The charger I ordered states: "USB C Output: DC 5V/3A". This leads me to believe it will put the phone into "Turbo" charging mode, but it won't actually charge as fast as the stock charger which is 5.7a. Oh well, it's better than nothing I guess. I can still use the stock charger when needed.

I literally cannot find any aftermarket charger that will put out more than 3.0 amps. I think thats as high as we can get right now and the Force charger is the only thing out there putting out above that.
Yea I don't think any aftermarket charger right now supports anything above 3a. Our stock charger has a thicker cable as well. Since QC chargers up the voltage and keep a low amp rating they can keep the cable smaller. Voltage doesn't necessarily need a thicker cable but current or the flow of amps does. For more than 3 amps the cable needs to be thicker for more current flowing. Our phones can handle 30 watts of power easily our stock charger outputs 28.5 watts. 15 watts is considered quick charging that's why our phone recognizes it as turbo charging. One plus has a charger that does 5v at 4a that's the closest I know of 20 watts. I would just like the stock charger to have a longer possibly removable cable. Our phones with 5v 3a are really charging the same as the other QC 2.0 and 3.0 devices it's all 15 watts
Back again, now with a bit more info. If the Moto Z Force truly does draw 5.7A @ 5V it follows neither QC-3 nor USB-PD standard. Both like to change voltages, but neither have 5V anywhere approaching 5.7A. Pg 471 of the latest USB standard shows that the max current delivered at 5V is to be 3A before being bumped up to 9V. QC3.0 adjusts voltages via 200mV steps (if anyone has a link to the official technical specifications of QC3.0 please share), but only outputs 18W max.
My next step is to fully drain the Moto Z Force, hook up the charger to a power meter, and measure how much power it truly draws until fully charged. I might have to make a measuring tool that independently measures the voltage and current of both VBus lines if further testing is needed.

Should be easier and give the same results. What I use.
---------- Post added at 06:24 PM ---------- Previous post was at 06:10 PM ----------
I've come to the conclusion that the USB hub I ordered is as good as it gets. It has 6 ports. 4 ports that vary the amps up to 2.4a, 1 QC 2.0 port, and 1 USB-c 5v/3a port.
I really hope Motorola / Verizon / Aftermarket companies are able to come up with a charger for this device. I love my Moto Z Force, but with the battery mods, I would like to have a charger for work capable of charging the mod as well. I don't know if I'd be able to survive with the 3ft one that came with it. I went out and bought all of the 3.0 accessories and threw out the boxes as well, thinking it would work. No USB A > USB C Chargers I've tried have worked. I'm anxious to hear if anyone has found one that works.
I reached out to Motorola Customer Service, the person had no idea what was going on. I have a Quick Charge 3.0 Aukey charger at my desk, Ampere says it's charging at 4.341v but no turbo power blurb. My buddy has the "Fast Charging" Verizon one, but it doesn't say it either. Hard to tell if it even has QC or not. They did however load the official moto charger (OEM) onto their webpage. I may just have to live with this one. :/
The one I have on order will certainly put the phone into turbo mode. I don't know how many amps it will do but it will be at least 3. As far as finding something above 3, well I couldn't. I ordered my own USB cable as well (C to C) and could have chosen any length. My charger is a hub with 6 ports and one is a QC 2.0 port. Couldn't find one with the fast USB-C port that also had 3.0.

So these chargers will all "turbo" charge our phones? I'm particularly interested in he car charger...I have an aukey QC 3.0 that I bought for this phone before realizing it wouldn't do the job lol...
But the usb-c port on the one you just posted will actually work right?...
At home I'm not too worried because I generally only charge my phone over night, so a slow charge or short cable isn't a terrible problem

Yes all those chargers should turbo charge the phone. Not as much as the stock charger, but still turbo. If you want a USB hub with multiple ports there are only like 2 options for those. There should be many options for single block home chargers and car chargers though. The hubs are the hard ones to get.

Does the USB certification matter for the cable? Is a USB 2.0 cable enough or do we need 3.0 or 3.1?

Quick Charge specs? Outlet?

So what do we call the "Quick Charge" that was used for the Nexus 6P? I know it wasn't the same as the quick charge in other phones at the time and it was kind of proprietary when it came out.
The reason I ask is because I need a new charger, but I was curious if there was a wall outlet (with usb ports) that would do the same thing.....Most of the wall outlets say 2.1amp 3.1amps or 4amps, which I assume is divided between the 2 ports if both are in operation. I also have a Nexus 9 so I'd like to be able to charge that.
Any tips or info on what specs I need to look for?

You can look over in the Accessories sub-forum where there is plenty of charger and cable discussion, but basically the 6P does not support the quick charge standard and ANY charger or cable that uses a USB-A port will NOT rapid charge your phone. You need a charger that either has a USB-C female outlet or integrated (non-removable) USB-C cable that supports the USB-C 5V-3A standard. That is the only way the phone will rapid charge. The N9 does not support the quick charge or turbo charge standards either. Mine came with 1.5A charger. You just need a good 5V charger that puts out at least 1.5A and the tablet will safely limit the input amperage. Since you have two devices to charge, you may consider a charger that has both a USB-C and USB-A port.

Fast charging information needed

So, I have finally learned what in my charger makes it fast. It uses the 5V and not the 9V, not sure why there's a 9V if phones use a 5V but I learned that the more amps the faster the charging. Like I currently have a ZTE 1.5A charger and a friend has a 4A dash charger for their OP3. Mine takes over an hour and their's takes a hour at most they claim. So if the V20 supports 3.0 charging, what's the most amps I can use in a charger to get the fastest charging possible? Would it be unsafe if I went to some extreme amount, like would it make my phone over charge and blow up or something?
The total power charged (watts) = voltage x amperage. So its a function of both volts and amps. For the fastest charging get a charger that supports qc3. This is standard that includes both how fast to charge and a signature that the phone and charger support qc3 to actually use the faster charging.
If you get a charger that doesn't support quick charge but some other standard the phone and charger will see that they don't support that other charging standard and charge at a safe slow rate.
The V20 does not support QuickCharge 3.0, that needs to be clear from the start because it causes a lot of confusion. The Snapdragon 820 does have support for the QC 3.0 standard, but LG chose for some reason NOT to support it. What the V20 does support is USB-PD aka Power Delivery which is similar to QC 3.0 in how it operates but it is NOT QC 3.0 (but the V20 does support QC 2.0 without issues with the stock charger).
USB-PD works like QC 3.0 in the sense that it does the charging in a different way that keeps the cells cooler during the charging process and doesn't cause the heat buildup that QC 2.0 causes. The factory LG V20 charger supports QC 2.0 and if you go into the hidden menu (*#546368*<3-digit model number>#, might not work on every variant) and then SVC Menu - Battery Test - Battery Info - select the Enable Log button - check the box for Battery Log Save On/Off and it will then show the relevant info. Once you see the information display, plug in whatever charger you wish and then wait and see what it shows for High Voltage parameter.
If it's QuickCharge it will show the version being used - the stock V20 charger shows me QC2 so that's QuickCharge 2.0. I have a Samsung QC 3.0 compatible charger and when that's attached it shows USB-DCP which from what I understand is Samsung's modified variant of USB-PD but that could be wrong. I did some quick research and found this so it could be limiting the charging to 1.5A which is perfectly fine with me):
Dedicated charging port (DCP) BC1.1 describes power sources like wall warts and auto adapters that do not enumerate so that charging can occur with no digital communication at all. DCPs can supply up to 1.5A and are identified by a short between D+ to D-. This allows the creation of DCP "wall warts" that feature a USB mini or micro receptacle instead of a permanently attached wire with a barrel or customized connector. Such adapters allow any USB cable (with the correct plugs) to be used for charging.

That was taken from this page:
https://www.maximintegrated.com/en/app-notes/index.mvp/id/4803
My V20, using the stock Samsung 2A charger that I always use (because I don't like to quick charge my batteries, I don't trust it in any form and I still think it's damaging the cells but that's my own personal opinion on quick charging overall), can go from 15% to 85% (I use AccuBattery set to 85% and it alerts me when it hits that point so I can unplug, this increases the overall lifespan of the cell I'm using as measured in years not per-charge) in about 55 minutes to 1 hour depending on whether I'm still using the device or letting it charge screen off. That's using a plain old vanilla 2 amp capable charger and when I check the charging current sometimes it'll actually show 2.2 amps (2200+ miliamps) so I'm perfectly happy with that situation.
I've read reports from owners of Pixel USB chargers and when they use them with their V20 smartphones and look at the battery info in the hidden menu it will show USB-PD so I might have to get one of those sometime and see how it goes.
Suffice to say, 55 minutes for a 15% to 85% charge for me is fast enough and the battery still stays pretty cool overall. USB-PD is probably the best tech we'll be able to make use of with the V20. I've read that the V30 does fully support QC 3.0 without issues and the the stock V30 charger is QC 3.0 compliant. The new V40 is QC 4.0 ready but I don't know at this moment whether or not the actual stock charger handles it but again, the QC 4.0 support is handled by the SoC and it remains to be seen if LG allows it or forces it to QC 3.0/USB-PD operation. Guess I need to do some research into that aspect of the V40 too.

The V20 can support QC 3 with a custom kernel, for example with mk2000 oreo 1.1 beta with a qc3 3 charger it indicates HVDCP_3 (HVDCP is one of the important parts of quick charge)
I've been using exclusively pd or qc3 chargers with my v20 and both properly work, verified with a usb power meter. Qc3 does the little 200mv adjustments as expected. Although to be fair i do run mk2000

Have always doubted whether it was QC 2 or 3 but the log shows QC2.0TA in the service menu. Voltages measured by an inline meter are closer to 9V and around 1.3A (only with screen off) which suggests QC2. Power in shoots up to 15W initially and then drops to 13W and then 11 something W.
QC3 would be closer to 7V something with a higher amp input.. That's what the QC3 power bank used to charge the V20 accepts when charging itself.
This is stock btw, not rooted nor using any roms.

I found this interesting and hooked up my 100W laptop usb c charger to the phone and then use a usbc inline meter and found it did quick charge. At the same rate as Qc2. The meter read 8.91V @1.5A . This is surprising as i'd have thought usbc operates at 5V and a higher amperage.
When i looked at battery test screen from the service menu, the item for High voltage TA status reads as OFF. Yet my plugable usb c inline meter records around 13.5W going in with screen off. The voltage was 8.91V 1.5A. That's not USB-PD afaik, which should have said 5 V and a higher current draw. My laptop charger does not do Qualcom quick charge at all, So i'm not sure what is going on here.
I've been wary of using my laptop charger to charge the phone as i'd read an early report that some people had a bootloop problem and it was caused by USB PD chargers.
The factory LG V20 charger supports QC 2.0 and if you go into the hidden menu (*#546368#*<3-digit model number>#, might not work on every variant) and then SVC Menu - Battery Test - Battery Info - select the Enable Log button - check the box for Battery Log Save On/Off and it will then show the relevant info. Once you see the information display, plug in whatever charger you wish and then wait and see what it shows for High Voltage parameter.

Fixed the code for you, it was missing a # before the * model number
If it's QuickCharge it will show the version being used - the stock V20 charger shows me QC2 so that's QuickCharge 2.0. I have a Samsung QC 3.0 compatible charger and when that's attached it shows USB-DCP which from what I understand is Samsung's modified variant of USB-PD but that could be wrong. I did some quick research and found this so it could be limiting the charging to 1.5A which is perfectly fine with me):

Interesting, when i hook up a ravpower power bank that is also QC3 comparible i still see QC2. It charges no faster than the stock charger LG includes in the box
I've read reports from owners of Pixel USB chargers and when they use them with their V20 smartphones and look at the battery info in the hidden menu it will show USB-PD so I might have to get one of those sometime and see how it goes.

Not in my case with a laptop charger, it just reads as OFF.. Do you remember where you read this maybe a link.
However when i use the laptop charger to usb C PD charge my power bank, the meter reads 4.89V 2.77A. That is a usb c PD charge. These are not the figures i get when using the laptop charger with the V20 as indicated above.
USB-PD is probably the best tech we'll be able to make use of with the V20. I've read that the V30 does fully support QC 3.0 without issues and the the stock V30 charger is QC 3.0 compliant. The new V40 is QC 4.0 ready but I don't know at this moment whether or not the actual stock charger handles it but again, the QC 4.0 support is handled by the SoC and it remains to be seen if LG allows it or forces it to QC 3.0/USB-PD operation. Guess I need to do some research into that aspect of the V40 too.

I have mixed views about USB-PD and its suitability for phones. Laptops have larger cooling areas and so USB PD is fine with them. My laptop has a 100W charger and its charging as i type this and i don't find the laptop gets warm at all. The history with the 6P & First pixel showed people with battery problems and having to replace the battery shortly after a year. Particularly with the 6P. Not heard any problems with the second gen pixel as yet. Maybe its still too early. But even with qualcom quick charge and i use it all the time there should not be any problems with battery after a mere year.
Having said all that in the last post I made, a friend gave me a Samsung EP-TA20JBE charger last night, go figure. It's the first Samsung "fast charger" that I've had and I decided to plug it into my V20 and see what it showed. I know that if you use the Pixel chargers the battery info in the service menu will show USB_PD meaning it's communicating and charging using the Power Delivery standard. My regular Samsung 2A charger - plain old vanilla non-QC compatible straight 2A charger - shows USB_DCP when charging my V20 so that's a known thing; there is no QC support, no PD support, nothing but just pure current provided as requested.
Here's the funny thing:
The Samsung EP-TA20JBE apparently is a QC 3.0 compatible charger, but since it's made by Samsung what I see under the battery info is USB_HVDCP which I've never seen before. So I did research into the USB_HVDCP meaning and of course the HV means High Voltage.
What I discovered is that if you're using a true Qualcomm compliant QuickCharge 3.0 device with a true Qualcomm compliant QuickCharge 3.0 charger, your device should report it's getting QC3.0 under the battery info but that's where the fun begins because non-compliant hardware will just show "USB_HVDCP. Of course, because this is not an LG charger and the sense and communication stuff is not from them, it's falling back to Samsung's version of QC3.0 protocols - but what I discovered is that in such instances it's actually Qualcomm QuickCharge 3.0 in effect, it's just that on non-compliant chargers Qualcomm detects the charging protocol as USB_HVDCP.
So, I ran my V20 down to about 15% using a battery app that forces the device to use nearly 100% of the CPU, that took the better part of 45 minutes or so, and when the phone beeped to alert me it needed charging I stopped the battery rundown app, let the phone sit for about 15 minutes idle so it would cool down, then I plugged in the Samsung USB charger I picked up last night (using my Monoprice 26 gauge USB-C charging cable).
Normally if I charge the device using that Samsung vanilla 2A charger from 15% it will cause my V20 to get warm on the backside because it's pulling the full 2A from the charger and of course it'll get warm. It also takes roughly 55 minutes to about 1 hour solid to go from 15% to 85%, and the phone will stay warm till about 65% when the current pull changes to something lower, maybe 1.5A, and it continues to decline as the actual charge increases and of course the V20 cools down to various degrees (pun intended) as the current pull decreases.
But here's what I noticed using this Samsung USB charger:
I watched the charging indicator (screen off, I use AccuBattery which shows me the current battery percentage on the V20's second screen) and it was literally going up 1% every 35-40 seconds which I had never seen before, all the way to 85%. My V20 remained basically cool to the touch from the moment I plugged in that charger to the time AccuBattery alerted me about the 85% cap - that's what I have it set for to ensure I get a longer lifespan (measured in years) from the OEM LG cell I bought back in August, manufactured in Nov 2017 by the date on the battery.
So, I'm not sure what this all means but based on what I read about Qualcomm and how their chargers ID themselves, if you see USB_HVDCP that is QuickCharge 3.0 under the battery info in the service menu - it's not Power Delivery because the Samsung charger doesn't apparently support that protocol (but I'm not 100% sure on that one).
It's actually honest-to-goodness QuickCharge 3.0, according to the info I read yesterday afternoon, so while I'm still not 100% sure on the protocols or the various naming conventions like USB_PD, USB_DCP, USB_HVDCP, etc (I mean I know what they stand for, sure) and how the V20 identifies the charging protocols and usage, what I can for certain is that for the first time since I've owned my V20, I can charge it with this Samsung USB charger and never feel it get warm at all so for me that's a huge positive. Li-Ion batteries HATE heat buildup, that'll kill their effective lifespan (again measured in years) more than most anything else.
All the vanilla 2A or 1.8A chargers I have cause the phone to heat up during the charging process. I have a Motorola "TURBO" 25 watt QuickCharge 2.0 compatible microUSB charger that I used for testing purposes with a microUSB-to-USB-C adapter and under battery info that identifies as USB_DCP so that's QuickCharge 2.0 (which that particular charger is designed for) and the battery heats up when I use it. This new Samsung charger I just got last night, charges just as fast if not faster and there is NO heat buildup whatsoever that I could detect so, yep, QuickCharge 3.0 even if it's not identifying as QC3.0 under the battery info.
I suppose what I said earlier is now considered moot: the V20 DOES support QuickCharge 3.0, just not with the stock LG charger because it's not a QC 3.0 charger to begin with.
So, yeah, I guess I'll be using this Samsung charger from now on.

Plain USB_HVDCP is quickcharge 2.0, when its 3 it shows as USB_HVDCP_3 (if you use a custom kernel like mk2000 and a qc3 charger its possible)
What made me think the V20 uses QC3 is the inline meter i used with it said so. This btw is from the stock charger too. But the voltages do not convince me
The voltage between qc2 and 3 are pretty much the same, but 3 has more levels in between the max and min voltage so less energy is wasted.
They're not the same. I remember a post from the HTC 10 forum and that phone comes with a QC3 certified charger and the volts were in the 7 range with higher amps. Which btw is the same as when my ravpower power bank charges with a QC3 compliant but not certified charger
So we still don't have anything absolutely concrete, great.
But as I said, with a QC 2.0 charger (the Motorola TURBO one) my V20 gets quite warm from 15% to 85%.
With this Samsung QC 3.0 charger, it doesn't get noticeably warm to any significant amount from 15% to 85% AND it gets charged faster.
So I have no idea and really just figured "OK, whatever, it charges faster and cooler, I'll use it..." and that's that.

Fastest Quick Charger for V35 - Via USB-PD or Quick Charge 3/4

So I'm trying to figure out whats the fastest charging method for the lg v35 available so i can buy a new charger with that capability. Anyone have any ideas what that would be?
For USBC i'm looking at 5V/3A, 9V/3A, 12V/3A, 15V/3A, 20V/3A , which of these usb pd options would it work with? Also is this phone a QC 3 or 4 capable phone? Thanks
Trying to see if this would increase my charging speeds:

My old Nexus 6 quick charge brick does nicely with a usb a/c cable
LG v35 is QC 3.0.
Neither or my Google PD chargers for my previous Nexus 6P will fast charge my LG v35, but my Huawei MediaPad M5 charger (FCP --> 18 watts) will. I think QC3 is a little more watts, like 22 so I'd get slightly faster charging w/QC 3 charger. Would really like to identify a charger that will fast charge across QC3, FCP, and PD. Not sure that Monoprice one will.
This device does PD up to 65 watts plus two 2.4amp us ports and also has one QC3 port. I love it.

Charger with PD + QC 3.0 for G6?

Hi,
Has anyone been successful in finding a 30+ watt Power Delivery USB C charger that also supports QuickCharge 3.0? Apparently the G6 is extremely picky and only accepts PD from a few chargers. Since I'm permanently travelling with this setup I don't mind if it's a charger with just 1 output.
Thanks for any suggestions!
drftr
G6 doesnt support PD, it only supports qualcomm QuickCharge 3.0
Thanks. I know but I have other devices that do. As I'm permanently travelling I'm looking for ONE charger and ONE cable that fit the bill.
https://gtrusted.com/how-the-lg-g6-charges-with-the-google-universal-type-c-charger-60w-using-usb-power-delivery
This site tests many qc and pd chargers with the lg g6 - search.
Anyways, LG G6 works fine with both types because it's built-in.
As long as you have a compatible PD charger, you'll be fine in the future with other devices, too. No need for a QC charger.
Thanks.
I'm familiar with their articles and it is exactly there that I learned most PD chargers DON'T work with the G6. Furthermore I've been contacting many companies and most agree on those findings.
For pocket-sized single port 30+ Watt PD chargers that DO work so far I have found:
Anker PowerPort III Mini (30W)
Choetech Q6006 (61W)
Choetech Q4004 (60W)
ZMI zPower Turbo HA-712 (65W)
UGreen CD127 (30W)
UGreen CD207 (45W)
Mu One (45W)
There's a few of which the company says it won't work while the manufacturer says it does:
RAVPower PD Pioneer RP-PC120 (30W)
RAVPower PD Pioneer RP-PC112 (61W)
Some of these are "rather exotic" and you'll find zero reviews. Interesting but not surprising was finding out that most of these are just made by one single company in Shenzhen. They just put your company specific logo there. So that's probably also the reason why the marketing pics on Amazon look amazingly similar.

Manufacturers of PD chargers also need to pay for a Quickcharge license and most likely will advertise this feature then. At least there should be a Quickcharge 1 compatible mode with 5v 2amps, which works for the G6. I had bought a QC3 (not PD) charger which wouldn't work properly with my QC1 devices, so i left my trusty old QC1 5port 8A (total) Anker charger in place.
Thanks for that...
I'm awaiting the arrival of the Anker PowerPort III Mini. Anker told me it would support fast charging for the G6 and so does their C to C PowerLine III cable. Let's see how long they keep working. This remark is not specifically meant for Anker products but I've read many horrible stories about PD chargers and cables in general.
