Charging Question

This may have been asked many times before but I am having a hard time understanding.
I have a bunch of Qualcomm 2.0 car and wall chargers. I just ordered a nexus 6p. I have ordered USB A to C cables to make the chargers work. What kind of charging speeds can I expect from this?
I know it will charge slower than if I hooked it up to the included charger. But will it charge as fast as the quick charge chargers or much slower like when I hook my phone up to a PC and it charges very slowly.

Cue @Elnrik
He the man for this question. Please ignore my below 'theory' in brackets.
(I would say, assuming your QC2.0 have the right resistors, they will only supply a max of 2.0A to the 6P which takes 3A from the supplied Google charger. So, in short, it should charge the same speed as your other devices but will take longer to go to 100% because the 6P battery is larger. The part i'm confused about, due to conflicting reports is whether the A to C cables can supply 2A from your chargers.)

So far in my experience the a to c cables charge much slower even with a QC 2.0 charger. I haven't actually measured it but I bought a type c to c charger and cable for my office and can get a full charge from 50% in less than an hour. I use my QC charger at home for over night charging. The charger that came with it had a short cable and was useless for my application so it just sits in a drawer.

I hope this explanation helps you understand better. Let me know if you have questions.
1) Quick Charge 2.0 will attempt to increase voltage at varying current levels to charge compatible Quick Charge devices. The 6P is not Quick Charge compatible, and it requires a constant 5V from it's host.
2) Type A ports do not have a cc pin (configuration channel) to identify itself or to negotiate current with type-c devices. That is why it is the cable which has to do this for the Type A port. It is the job of the Type A to C adaptor/cable to identify (via the correct pullup resistor) to the Type C device that a legacy USB connection is in place. Using the wrong pullup resistor in a cable is akin to deliberately posting a 55mph speed limit sign in a 25mph school zone. When the Type C device sees the resistor in the cable, it knows it is connected to a non-Type C port, and will then use other means to negotiate for power. BC 2.1 (battery charge) protocols are used over the USB 2.0/data wires, and if that fails, it just defaults to legacy current rates.
I hope this post explains things a bit better: http://forum.xda-developers.com/nexus-6p/accessories/usb-type-c-vs-usb-3-0-3-1-vs-usb-2-0-t3221676
So, the short answer is: using compliant cables, your chargers should provide 1.5A to the phone, which is the limit of BC 2.1. If the chargers do not use BC protocols, then 0.9A or 0.5A should be provided. Just make sure to use compliant cables.

Can I use regular 2A charger with N6p?

There are no many adapters on the market and I couldn't find original huawei adapter. Can I use a regular adapter (samsung 2A for example) with my Nexus?

Yes, but you must use a certified cable. Check Benson Leung's reviews on Amazon to find a good one or use the cable provided in the box.
However you can buy original charger from Google Store or a valid alternative from Amazon like this:

If I understand correctly some articles USB A chargers doesn't support type-c power profile, so the phone will charge at a constant rate without lowering amperage to be gentle with the battery. Furthermore the quick charge is a very useful feature, so I suggest you to buy a compatible charger.

Absolutely. Just be aware that charging of the Nexus 6P/5X is limited to 1.5A over a proper USB Type-A to USB Type-C cable. With a USB Type-C to USB Type-C cable and a Type-C charger, it charges at up to 3A (as it does with the official charger).
So if you're worried about speed of charging, you may want to get yourself a new USB Type-C charger, as a Type-A charger will take about twice as long! (a 3A USB Type-C charger takes about 90 minutes) Personally, I just have a USB Type-A charger by my bed, since it will definitely finish charging while I sleep. Then I keep the original charger in my work bag, in case I need to quickly recharge during the day!

I don't know if that's the case, but if it is, I'm not sure it matters. With the USB Type-C charger it's drawing 3A and then lowers as the battery gets full, but I don't know how low it gets. Whereas a USB Type-A charger will be drawing 1.5A maximum, so it may not even need to lower.

Any good USB type A charger that you can recommend?
I Have a good opinion about Samsung adaptive charger that my wife uses with her note edge.

I am partial to Anker brand chargers. I would suggest the PowerPort 2 (as I own a couple), it is capable of charging two devices at up to 2.4A each (while the Nexus 6P can only draw 1.5A, iPads can draw the full 2.4A because of their proprietary tech). But as you can see on the Anker website, they have a ton of different options!

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.

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!

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.
