I've been looking and looking for a good and not-too-expensive USB-C wall charger and I'm having trouble finding one. On Amazon there appears to be a $25 option that looks good but expensive (imho) and then there's a cheap ~$10 option that seems to have bad reviews.

I know there are a ton of USB-A -> USB-C cables & adapters but I also want some native USB-C options since it can power things 50% faster than what USB-A -> USB-C will do. I also know there are several decent-looking USB-C car chargers

Has anybody found any good USB-C wall chargers that aren't too expensive? Or are we stuck waiting for the likes of Anker, Choetech, and others to come out with some good options?
[Nexus 6P Accessories] Chilidog:
You could just get another google one for 25
[Nexus 6P Accessories] toyanucci:
I am looking for cheap alternatives as well. I travel a lot and rather have a couple chargers for travelling. Re the suggestion of buying another one from google, I would prefer one with a longer cable. I see many 6.6 ft cables on amazon that would work great with a usb c power brick.
[Nexus 6P Accessories] RED ZMAN:
Links to the ones that you found?
[Nexus 6P Accessories] bombaw8:
most of those longer cables severely reduce the charge current. to the point some of these cables can not even charge the phone while it's in use.

i have no idea how the quick charge on 6p will work but based on what i'v read it is heavily dependent on the usb-c ability to carry higher current, so i would be very weary about longer cables.

if anyone out there lands a decent 6ft cable that can qc 6p at a good price. please be sure to report back. and no, i don't mean those cables listed at $20 a pop like the official google ones. i feel it's a rip off even at half of that price. LOL.
[Nexus 6P Accessories] dwswager:
Don't get confused among the connector type, cable type and charging standards. There are still USB 2.0 and USB 3.0 cables. The 3.0 cables will carry higher speed data and higher power than USB 2.0 cables. They are also more expensive. The 6P is only USB 2.0 compliant. Type A, Type C and Micro B (USB3.0 ugly wide connector not used by any phone) connectors will all carry high power and higher speed data streams. The current micro B that is used in most phones will not.

That said, the 6P is Snapdragon 810 SOC that supports QuickCharge 2.0. The 820 will support 3.0. Quick Charge 2.0 supports voltages of 5V, 9V and 12V and typically will be 2A at 5 and 9V and 1.5A at 12V.

Bottom line a USB 2.0 cable with any end if fed the correct voltage/amps will be Quick Charge 2.0 compatible. Most Quick Charge 2.0 phones use USB2.0 Micro B.
[Nexus 6P Accessories] Pilz:
Why do you keep spreading false information? It's not the chipset that dictates the charging jts the lower control chip that's desperate. This needs to stop because this is the 3rd time you said its supported. Google clearly stated there will be no QC 2.0 support even if they have the right PCU (power control chip) it would be disabled by default like in the OP2 and require a dev to enable it. The 6P doesn't natively support QC 2.0 and might not even have the hardware to if you could bypass the software side.
[Nexus 6P Accessories] toyanucci:
I just checked out the Indian unboxings which are making their rounds. I'm happy to see a plain old usb brick separate from the cable. I know that's not how the USA will be but it means that those usb bricks should be readily available soon enough from other manufacturers as I really want a compatible 15w brick that I can use with a 6.6 ft usb c cable for more length.
[Nexus 6P Accessories] htowngator:
Exactly. I think that's the issue here.

To get true "quick charging" it has to be a 5V/3A usb-c charger.
[Nexus 6P Accessories] Elnrik:
Pilz is correct. Regardless of chipset compatibility, they've skipped QC altogether as USB Type-C natively provides the power profiles needed to accomplish the same.

-ONLY- USB Type-C ports or chargers will power the correct pins/wires on a Type-C cable to fast charge the Nexus. Therefore, the best advice is to always buy a USB Type-C device for charging. Of course, check to ensure it outputs at least 5V @ 3A (15W).

As the Google sold Nexus power brick is out of stock, the one for the Pixel will work. It's overkill, actually, but will still work.

https://store.google.com/product/universal_type_c_60w_charger
[Nexus 6P Accessories] htowngator:
I assume the dual-port will be available soon when the 6p launches.

The Apple usb-c is 2.4A peak so it doesn't work either.
[Nexus 6P Accessories] dwswager:
Do you think Qualcom invented the idea of boosting voltage to supply more power more quickly? Did you know that almost every cell phone has an FM radio built in. It's on the chip. If it has a GPS radio you can bet it can do Frequency Modulation.

And the Snapdragon 810 is a System on a Chip! Look at the specs for it. It's all in there. Unlike the A9 from Apple. It's why a phone with the 810 will never be capable of doing QC 3.0! It's not in there.

[IMG="810 SOC"]https://www.qualcomm.com/sites/ember/files/snapdragon-processors-810.png[/IMG]
[Nexus 6P Accessories] htowngator:
smh....
[Nexus 6P Accessories] Elnrik:
I'm sorry, but how does that in any way relate to the topic?

I believe what you're failing to understand is that there is more than just the chipset or SOC that goes into charging the phone. The USB port itself has a controller which negotiates power profiles and communications across the port. This would/does completely bypasses the QC capabilities of the soc.
[Nexus 6P Accessories] Pilz:
I stated this before and I'll state it again. We don't know what PCU the 6P or the 5X have so we won't know if the hardware support is even there. According to Google its not supported so I doubt I had the right PCU. Type-C fast charging doesn't ramp up voltage like QC does it ramps up the amperes at a constant voltage.

Read this article here and enjoy the satire in it as well (the purposely crossed through the quick charge at the time of publishing the article from what I recall) http://www.androidpolice.com/2015/0...ck-charging-or-wireless-charging-of-any-kind/

Also this is Qualcomms approved list of PCU chips that support it (see picture)

It states that QC is supported in the SD810 but ylh need to have the necessary power control chip as well to enable it.

I doubt Google would have the power chip and refuse to enable it like OP did with the OP2 due to licensing costs. Obviously Qualcomm didn't invent raising the voltage and since you are new here this isn't reddit we don't spread false nonsense for fun.
[Nexus 6P Accessories] Pilz:
I cited and article to support what you said and attached a screenshot too :)
[Nexus 6P Accessories] dwswager:
We seem to be confusing the implementation of a technique with the technique itself. Yes, I know there are lots of controller chips within any device. And yes, a manufacturer can deactivate or more correctly not activate in the 1st place a features built in. To which the FM radio that is built in is not activated.

Bottomline is to try the native charger, a QC 2.0 charger and a basic 5V charger and compare the results. I will bet there will not be a significant statistical difference between the native charger and the QC 2.0 charger an both will outperform the straight 5V number. Time will tell.

No worries! Let me take a look into your question.

It looks like it will be available next Monday for purchase.

thank you
[Nexus 6P Accessories] Elnrik:
So, when the phone can't negotiate a 5 volt 3 amp power connection with a QC charger, and defaults to 5 volt 550 mA USB 2.0 defaults, you are saying that there will be no noticeable charging differences between 15 watts and 2.75 watts?

I'm not trying to be a jerk, I just don't understand what you think you understand.
[Nexus 6P Accessories] dwswager:
This one here will work! http://smile.amazon.com/Charger-Universal-Exchangeable-Included-Motorola/dp/B0122P71FC/ref=sr_1_6?ie=UTF8&qid=1444758012&sr=8-6&keywords=5V+3A+charger

I find it hilarious that anyone would think that a the connector on the end of the wire would have anything to do with the output of the power supply. You guys do know you can buy USB Type C to Micro USB adapters that go both ways. The only thing Type C brings to the table is it is reversible. The best part of Type C is that Apple is adopting it so we will have one standard all wired the same way. Only an idiot would wire a standard connector in a non standard way making their product incompatible with everything else. Micro USB-3 will carry just as much power and data just as fast, but it is really big and ugly!

Whether you use a 5V/3A charger or a QC 2.0 that will also output 5V/3A among it's 3 voltage settings is a mute point.
[Nexus 6P Accessories] Pilz:
He's too deep into thinking he's correct so there's nothing that can be done at this point. Unfortunately people forget to research before posting something these days and may make an incorrect statement but I would hope these people would validate their claims with data yet I have yet to see it. My QC2.0 charger doesn't go above 1.8A at 5V if the Type-C would even allow that lol
[Nexus 6P Accessories] Elnrik:
Ohh, good news. I didn't get a spare. Will have to keep an eye on that come Monday. Thanks!
[Nexus 6P Accessories] htowngator:
ugh, honestly dude just stop it
[Nexus 6P Accessories] dwswager:
Please explain what is magical about a 5V/3A charger sold by Google and one sold by anyone else?

You seem to think it is the magical Type C connector on the end. If you take the Google captive charger. Cut the cable. (I assume it only has the power leads) Wire a Type A female plug on it. Then use the A to C cable provided, you will get the same power out the other end of the WIRE! It's a FREAKING wire!
[Nexus 6P Accessories] Elnrik:
No, I seem to think it is the "magical" type-a port you will be connecting the cable to.

http://www.usb.org/developers/docs/usb_31_072715.zip has all the data you need to know, and I'll help you find the info. Open the USB 3.1 r1 PDF. Go to section 11.4.5. Observe maximum voltage and amperage outputs from type-a ports.

Open the Type-C specification PDF. Go to page 23. Table 2.1 shows the summary of power supply options across a Type-C port or cable. Legacy USB power is supported along with USB Type-C specific power ratings which ONLY a Type-C port will supply.

Feel free to explore the documents. The wiring diagrams are somewhat interesting, although I found the protocol specifications to be boring.

I hope that helps.
[Nexus 6P Accessories] aaron_huber:
A wire is a wire, but in this case the magic is in the charger, the device, AND THE CABLE. From the USB-C Wikipedia page:

Full-featured USB Type-C cables are active, electronically marked cables that contain a chip with an ID function based on the configuration data channel and vendor-defined messages (VDMs) from the USB Power Delivery 2.0 specification. USB Type-C devices also support power currents of 1.5 A and 3.0 A over the 5 V power bus in addition to baseline 900 mA; devices can either negotiate increased USB current through the configuration line, or they can support the full Power Delivery specification using both BMC-coded configuration line and legacy BFSK-coded VBUS line.

The 6P does not support the full PD spec per Google, but it does use the "configuration line" which is an extra wire in the USB-C cable hooked up to an extra pin in the phone/charger to talk to the charger and negotiate extra current. If you don't have a USB-C cable with the extra pins/wires plugged into a USB-C charger on the other end that also has the extra pins to do the negotiation, then the phone will fall back to a lower current because the spec requires it. If you plug it into a USB-A charger or use a USB-A to USB-C cable then all you get are four wires - the "configuration line" to do the negotiation doesn't exist.
[Nexus 6P Accessories] Elnrik:
Kudos! Put it better than I could. Thank you.
[Nexus 6P Accessories] PaisanNYC:
*moot point.

A Moot point is one of those phrases that once had a firm and well-understood meaning, but no longer does. It was just as you say: a matter that was uncertain or undecided, so open to debate. It comes from the same source as meet and originally had the same meaning.

If you are going to troll on the internet, get it right...
[Nexus 6P Accessories] dwswager:
I apologize for the confusion some of my posts may have caused. I assumed things not in evidence. Why Google would not avail themselves of the QC 2.0 option even though it requires a separate control chip (unlike QC 3.0), I have no idea. No one really knows what the Google Nexus 6P uses because Google has not specifically stated. They have hinted and others have guessed that they are using USB Power Delivery (USB-PD), but I doubt it. My bet would be a simple continuous 5V/3A 15W charger sans QC2.0 or USB-PD.

[IMG="USB Power Delivery Profiles"]http://www.pcdiy.com.tw/webroot/data/media/c651dbfdc62361145f6d49fcbdf719b6.jpg[/IMG]

As seen from the USB-PD profiles, 5V/3A is not in the USB-PD spec. It comes from the USB 3.1/Type C spec.

Also, USB-PD is available with non Type C to Type C Cables. Cables with legacy connectors (Non Type C) can be passively marked as USB-PD compliant (DETECTABLE). Type A to Micro B supports up to Profile 4 and Type A to Type B supports up to Profile 5.

And QC 2.0 and USB-PD are not mutually exclusive and can coexist in the same devices. In fact, QC 2.0 is within USB-PD Profile 2 specifications. They just added a 9V capability that I believe is 1.5A.

[Nexus 6P Accessories] Elnrik:
Can you tell us how you chose that graphic, and why you would cite it as proof of your statements? It currently lists as being linked from http://www.pcdiy.com.tw/webroot/data/media/c651dbfdc62361145f6d49fcbdf719b6.jpg. I'm not familiar with PCDIY.com being a governing authority on USB specifications. It appears they are a media outlet of some kind reporting on IDF. The IDF14 (Intel Developers Forum) was over a year ago. The information I've cited comes directly from USB-IF technical documents published 07/27/2015. See here: http://www.usb.org/developers/docs/usb_31_072715.zip

The spec papers from USB.org seem to directly contradict the information in your slide.

It seems like you are googling around without reading deeply into or fact checking what you see. What you are assuming are fact sheets I believe are presentation slides - used before specifications were finalized.

Please understand, I put this information up NOT to make you feel bad, or to win an argument. I'm putting it up to ensure the community has the correct facts and to eliminate confusion. Perhaps further conversation should happen via PM if we are to continue the debate?

Thanks.
[Nexus 6P Accessories] Pilz:
Why is he still arguing? You have thoroughly proved him wrong
[Nexus 6P Accessories] fury683:
So I didn't read this entire thread, but got the jist of it that if you really want the best charging speed, you need a C to C cable/charger. The 6p ships with an A to C cable that you can use with your existing standard USB power supplies. I assume that cable will charge, but not as quickly as the C to C? I currently have the Nexus 6 and use the OEM Quick Charge brick in my living room, with the OEM charger from my Moto X 2013 in my bedroom. I don't need the fast charging at night so the lower rate is fine. I plan to use the supplied C to C cable/brick in my living room and the A to C cable in the bedroom at night.

My question is, I have a Motorola Quick Charge USB car charger that is just a single USB port. If I got another A to C cable, that would charge as well, just not as quickly, right? I intend to get a C to C car charger setup eventually, but don't necessarily need OEM at launch. The supplied cables should be enough to get my started and give me time to order more once people confirm what is working and how.
[Nexus 6P Accessories] Elnrik:
To the best of our knowledge, that is correct.

My specific issue with quick charge is that there are precious few specifications published by Qualcomm that I've been able to find relating to how a QC charger will respond (negotiate) with Type-C devices like the Nexus. Type C spec states it will only accept 5 charging power profiles (6 including PD), and *I ASSUME* only the basic 2 profiles (USB 3 and 2 charging rates of 5V at .5A or .9A) are going to be provided by QC chargers. Here is why I assume that:

So, pretend you are a QC charger. A device connected to you either IS or IS NOT a QC compatible device. If it is not, what do you do? You use minimum USB 2.0 or 3.0 compatible charging power because you don't want to blow up the device on the other end of the cable, right? Sure, in the case of the Nexus, both devices can provide / receive way more than .9A of current, but there's no way for either device to know that. The Nexus doesn't know how to speak QC without the proper QC chip/controller-thingy working, and the QC charger doesn't talk USB Type-C because it doesn't have the pin/wire to do so over Type-A plugs.

That's my simple-as-I-can-make-it way of looking at it.

Hey, if he's trying to learn, more power to him. I've been on that side of the coin before. I had a professor literally threaten to beat me unconscious with knowledge, if that's what it took for me to "get it". Good thing I "got it" before he did so. I really think he would have done it. (Nobody likes organic chemistry anyway.)

And keep in mind, it can really suck to be wrong, especially on a public forum with a few thousand views. Hell, imagine if everything I've put up on here about USB is incorrect. I've been linking specs sheets like it's holy doctrine across 4 or 5 USB threads. How embarrassed would I be then? Doesn't mean you shouldn't keep trying to learn it though. Debate is healthy. (The snide remarks and discouragements I see here all too often are not.) Just gotta do your research as best as you can, I guess.

[Nexus 6P Accessories] redrob222:
This whole power output is so confusing. Maybe I'm missing something but with all these spec docs which I'm sure are true doesn't explain why a pretty reputable company like Anker would sell a product like the Power Power 2 (dual usb-a, 4.8A max output, 2.4A per port). According to the specs that output can't be reached with usb-a. Is that correct? Am I missing something? This whole discussion is giving me a migraine.

Thank you Aaron!
[Nexus 6P Accessories] tkoreaper:
I'm confused... Why are you guys wanting a USB-C wall charger when the phone comes with everything you need?

- USB Type-C 15W (5V/3A) charger

- USB Type-C to USB Type-C cable

- USB Type-C to USB Standard-A plug cable

What more do you need? Everything is separate... the two cables and the charging brick.
[Nexus 6P Accessories] init_dot_t:
Easy, to have more than one charger that is type c to type c.

[Nexus 6P Accessories] htowngator:
It will be a while, but you'll save maybe $10? I guess if it matters for you. I really needed a 2nd charger for the road.
[Nexus 6P Accessories] toyanucci:
Na, would be way more than 10 bucks lol. I'm sure anker etc will drop some 2 port or more with 15w each for less than that 40 bucks but I do get that you need one for travel. Those who can wait will, those who have the need will have to just get what's available now!
[Nexus 6P Accessories] htowngator:
You're forgetting the data cable which can be $15 even now on Amazon.
