Hello,
Id like to know which quick chargers are compatible with the V40? I know it comes with a QC 3.0 in box but will a QC 3.0 Samsung S8 charger work just as fine?
Id rather not take the chance to damage a device, or is it better to just purchase OEM LG quick chargers?
From my understanding, QC is a standard by Qualcomm, so any charger following Qualcomm QC standards (it should say if it supports up to QC 3.0 for example) will work fine. It is not OEM dependent, and a bunch of brands like Aukey make third party QC chargers. Your S8 quick charger will work fine.

Hi,
CM roms or GPE ROMs support fast charging ? beacuse with my Samsung Fast charger it has a very slow charge like complete in 2-3 hours.
Thanks !
Samsung charger won't work on this device for fast/quick charging. You can blame Samsung for that (or for manufacturers not all using the same fast charge standard). Samsung does not use the Qualcomm QuickCharge standard, inherent in the Snapdragon chipsets. Samsung decided to use their own proprietary fast charge technology, which only works on their devices. Probably at least part of the reason, is that Samsung does not always use Snapdragon processors in their devices.
With the M8, you need to use a charger that specifically supports Quick Charge 2.0, which will either say QuickCharge 2.0, and/or have the QC logo like this: http://www.androidcentral.com/sites/androidcentral.com/themes/android_visor/images/badges/quick-charge.png
Also, QC 3.0 compliant chargers will also work on this device, but at QC 2.0 speeds (not the faster QC 3.0 charge rates). Might be a consideration if you are going to buy a QC charger, and want some "future proofing" for a possible future QC 3.0 device.
I was reading that some higher amp rated chargers (not QC compliant) may charge slightly faster with QC devices, but you'll never achieve full QC charge rates. And from what you're seeing (and others have reported similar) is that the Sammy charger doesn't give you any faster charging then the "standard" (non-QC) charger that came with the M8.
Not sure (not a CM or GPE user myself), but I believe with the proper charger, QC 2.0 will work on the device, regardless of the ROM, as the feature is built into the chipset hardware itself. But you can probably check the ROM threads to verify that.
Hey all,
I noticed that when I plug my Pixel C into my HTC 10 charger (quick charge 3.0), my Pixel displays "rapid charging." Considering the tech specs involved, this seems to make sense. QC3 is able to scale its voltage and amperage, and covers the 5V3A 15watt combination that the OEM Pixel C charger uses. When my dog chewed the original pixel charger, I bought another 3rd party QC3 charger, with the same "rapid charging" result. This has lead me to believe that QC3 chargers are capable of supporting USB PD, despite having a USB A adapter involved.
Considering the Galaxy s6 was compatible with QC2 despite having an exynos, and this isn't too far fetched. However the inverse doesn't seem to be true. The oem Pixel charger does not seem to "rapid charge" my HTC 10, despite the device's technical ability to support USB PD, and a 5V3A charge *should* appear as a quickcharge. It is possible it is charging via USB PD, but not display rapid charge, as the HTC 10's software could be configured to quick chargers. So while it receives the 15W charge, because there is no voltage scalability, it wont accept a "rapid charge" status, since the device cannot go to a full 18watts.
This leads me to believe that stockpiling QC3 USB C chargers might be the way to go, instead of USB PD. Since QC3 can support both, it's a no brainer as tech companies battle which standard will survive
I come from a Nexus 6P that also had a USB C port. Today I needed to charge my phone and the 6P charger was next to me. But, knowing all the issues there are/were with USB C, I decided to search before using the charger and I found this article:
http://www.androidcentral.com/my-htc-10-hates-pixel-c-charger
After reading this article, I found some threads speaking about this and decided that I would stick with the official charger only.
But, I got curious. When this information came out, the phone was pretty new. Were there any new findings regarding this in the meantime? Is it really mandatory that I only use the official charger unless I want my phone to turn into a Note 7?

Google does not support Quick Charge technology forced by Qualcomm. They go with proprietary USB Power Delivery. So no wonder Google charger does not work with QuickCharge enabled phones.
I think HTC is to blame here though. They should have gone with USB C standards, not Qualcomm's.
So, we should stick with only the official charger I guess?
You can basically use any charger but just to be on the safe side I would stay away from the USB-PD chargers. USB Power Delivery and Qualcomm Quick Charge differ quite a bit.
"Any charger" being anything that's a basic 5V USB charger whether it's a 1A or 1.5A or 1.8A or 2A or 2.4A... Or any Quick Charge 2.0 or Quick Charge 3.0 charger.
And if you want to be extra safe, only buy chargers from reputable brands and in the case of Quick Charge chargers, pick one from the certified list.
https://www.qualcomm.com/documents/quick-charge-device-list (PDF)
If you come across a QC charger that's not on the certified list, you can ask yourself: has the manufacturer certified any other products? If they have, you're pretty much good to go. If they haven't, well ask the manufacturer why they haven't certified any QC products they make. Another good question for a charger manufacturer would be to ask what power controller are they using in that product? If the power controller is certified then, well, that's that. I'd say you're good to go as the power controller is the brains of the whole operation.
I personally have a Tronsmart CC2TF charger in our car, it's not on the certified list but they have certified a dozen different accessories in the past so I'm not even slightly worried. They make good products.
P.S. @cavist Qualcomm doesn't force anything. If an OEM doesn't want to use Quick Charge on their device then they will not use it. Whoopdy doo, big deal.
Also USB-PD is non-proprietary, royalty-free spec in contrast to the proprietary, royalty-free Quick Charge spec.

I mismatched the words and meaning, thanks for correcting this. As for forcing issue, I meant that almost every device with Snapdragon with QC is using that feature and the company is advertising their power delivery standard which anybody would expect opposite to Google which is relying on approved USB PD specification. It is strange that so many big companies choose the QC and not proper USB PD in its place while having a free hand in choosing the charging standard.
I just purchased an LG G7 ThinQ on Verizon in the US, coming from an LG Optimus G Pro, purchased in 2013. It's being shipped right now, so I don't have it to play with.
With that said, I'm a newbie to quick charging. I see that the phone comes with a QC 3.0 block, and that the phone is listed as being QC 4.0 compatible, as per Qualcomm's website.
I'm looking to order all new cables and chargers to take advantage of the higher charging speeds that this phone can allow. I'm not understanding though whether I'd be better off buying a car charger that is QC 3.0 or has USB PD. I realize that the USB PD would be the way to go for laptops and larger items, but for our phone, is there any difference? I do realize that I'd need a dual-ended USB C cable for the PD charger.
Also, has anyone tried using a QC 4.0 charger on the phone, and although Qualcomm says the phone has the 4.0 hardware, has LG enabled us to use it?
So the LG chargers can deliver 9v 1.8A.
The phone will recognize my 18w and other 45w PD charger, but I haven't managed to see any difference in the charging speeds, and more annoying, charging is pretty slow when screen is on.
I wanna buy a USB meter (PD compatible) to see what's the phone actually asking for, but I assume that it just sits at 15w max.
The reason I have a PD charger is because it allows you to have longer USB-C cables and it's compatible across more devices, like I can fast charger my Huawei Mate 10 pro with it, you can also charge iPhones with it.

This thread could be useful for you too: https://r.tapatalk.com/shareLink?ur...share_tid=3787343&share_fid=3793&share_type=t
USB PD is an entirely different language than QC 2-4. They negotiate and handle power different from each other. If you plug USB PD into a QC device it should default to 5v, 1 or 2 amp standard charging.
Use only QC 3.0+ equipment. That will get you the rapid charge you're looking for as it speaks the right language for the phone. I dont believe LG has enabled QC4 standards in the firmware although the chip supports it.
LG G7 is also wireless rapid charge, i get an almost QC speed on a 15w ravpower and umdigi wireless pads. Took me a few to find ones that were quality and charged fast. Most of the "10w" chargers dont actually put out 10w so they dont charge fast.

QC 4.0 is actually compatible with Power Delivery, Qualcomm did that in fear that Google would make PD mandatory.
And there can be handshaking between previous QC devices and PD chargers, since the most basic profiles are kind of standard (max 9v 2A).
So in this way I can fast charge a S8, the LG G7 and any other QC device with the PD charger and I can charge other PD and QC devices with my Huawei fast charger power bank (it's based on QC 3 delivering max 9V 2A).

Funny i was just reading an article about that. I suspect that would be a firmware compatibility issue again, as in: did LG enable it.
Great feedback and perfect timing

I just wished that phones would support higher charging rates via the PD standard.
I'm mostly sure that neither the S8 nor the G7 are taking full advantage of the max power output of their charger for long.
I thought that the charger might be under delivering, but connecting my PD 18w charger results in the same situation, I still need to measure it (need to buy a USB meter to have more details).
But using the same 18w PD charger I can charge the Mate from 20 to 50% much faster than I can charge the G7.

hello , can i use samsung s6 charger for fast charging on my htc m8 ?
Unfortunately, no. It has to be a charger which bears the Qualcomm Quick Charge logo like this: https://goo.gl/images/vZLCZB
Either the lightning bolt symbol, or the charger will say "Quick Charge 2.0" etc. on it.
The M8 specifically supports QC 2.0, although other official QC chargers will work, to some degree. QC 3 and 4 chargers will charge at QC 2.0 speed (not as fast as QC 3 and 4). A QC1 charger will work (faster than standard charger), but not as fast as QC 2.0 speed.
Unfortunately, Samsung uses their own fast charge technology, which isn't compatible with other brand devices (such as HTC). Blame it on the phone manufacturers, who are trying to differentiate their products with their own fast charge technologies. Breaking the native Qualcomm Quick Charge function, even for devices (such as Samsung, and there are others) that use Qualcomm Snapdragon chipsets.
it doesn't have this
