I don't have a USB-C PD charger, and can't find much information on if the Note 7 will use the full 15W provided under the USB-C spec, does anyone know?
For example, has anyone plugged a Macbook 12" USB-C charger into a Note 7?
I have a 100W USB dock/charger (Dell TB15). It uses a USB C adapter, but I'm afraid to plug it in to my phone.
I just bought my first Google pixel tablet with a USB C charging point. Is it faster to charge USB C to USB C?
Or is USB 3.0 2 USB C the same speed?
Thanks
I know with my lg v20 if I use my USB c pd charger with it. It charges faster than my 3.0 USB A to USB c charger. So I would guess same holds true with the pixel c.

USB-C and USB 3.0 are two completely separate things. USB-C is merely a connector type. The default protocol for USB-C is USB 3.1, but if anything in the connection is incompatible with 3.1 then it will reduce down to whatever the lowest is. For instance using a USB 3.0 cable on a 3.1 connection results in 3.0 speeds/power. Likewise, if you use a tablet/phone whose physical port is USB 2.0 with a 3.0 cable it will still only go at 2.0 speeds.
What really matters here is your power source. The Pixel C supports USB Power Delivery for fast charging. The included charger is not PD-capable and will charge at 15W ([email protected]). The Google 60W USB Type C charger (included with the 2015 Chromebook Pixel) will charge the Pixel C at 24W ([email protected]) Another thing to keep in mind when considering chargers is that Qualcomm's Quick Charge isn't the same as what the Pixel C uses and likely will always default to 5V/2.4A charging so make sure you use a PD-capable charger if you want to get the fastest charging speeds.

That's very informative. How quickly does the pixel charge when at 12V/2A?
All very useful information. Thank you.
I have a feeling that fast charges can eventually cause damage to a battery or at least reduce its life expectancy.
I don't know why but I have the impression that slower charging – if one isn't in a hurry, such as overnight will eventually give longer battery life – especially interesting in a unit which doesn't have a user rechargeable battery.
Got any comments about this?
I would suggest this reading: http://www.fpvforme.com/charging-lipo-batteries/
Just make 100% positive you're buying a good USB C Power Delivery compatible charger+cable, if not you risk damaging your Pixel C.

Hi all,
I just have some clarification questions regarding the chaos that is currently USB-C. Will ANY USB-C with PD support charge any other USB-C phone, tablet, or laptop if those devices support PD? Do we need to ensure that the charger used supports specific charging voltages, or will any of them work at different charge rates?
I bought a 2017 HP Spectre x360 13" a few months ago. (SIDE NOTE: If you're looking, this is an amazing convertible Ultrabook... 4k screen w/ Pen, Core i7, 512GB NVMe SSD, 16GB RAM, Thunderbolt3). It charges via a 45W USB-C charger. I generally have laptop chargers everywhere, so I ordered a bulk of Dell LA45NM150 chargers from eBay. They say 5V/20V on the sticker. Should these also charge my Galaxy S8, which charges at 5V and 9V? Do chargers need to say Power Delivery or PD to meet PD spec, or does that come along with having multiple voltages.
Likewise, I am guessing my laptop NEEDS 20V to charge? So if I took say, a phone charger and plugged it into the laptop, would it just not charge since it can't switch to 20V?
I am also speculating that if a USB-C charger only says 20V on the sticker, will it fry a Galaxy S8? Or is there protection for this sort of thing?
I am no newbie to power, chargers, electronics, tech.. but there's a lot of gray area right now on this stuff it seems.
Anyone?

Also, another related question -- Is there any advantage to using a USB-C to USB-C charging cable and brick vs a USB-C to USB-A cable with a brick?

USB-C to USB-C supports ThunderBolt 3 and USB 3.1. So faster data transfer and charging... USB-A does not support this... I think....

So then, why put a USB-C port on a wall charger? Just so you can use the same USB-C to USB-C cable?

Yeah I guess so... USB-C will be universal soon enough anyway so this will no longer be a worry haha!
I was a bit surprised to find out that the Pixel 2 doesn't come with a transfer cable, and the only adapter is USB-C to USB-A. Luckily I still had mine from the original Pixel XL, but it was odd that Google didn't include one. Just a heads up for those who haven't received there's yet
That adapter allows you to use your old charging cable to transfer. Adapter into the Pixel 2, old charging cable into adapter and into old phone

I was surprised as well to see no USB-C to USB-A cable included. I also used mine from my original Pixel XL, but Google's cables are of such high quality that I would have loved to have another.

Correct, but this post isn't really about the adapter. It's about Google including one less cable versus last year. The original Pixels included the adapter, a USB-C to USB-C cable, and a USB-C to USB-A cable. The USB-C to USB-A cable is not included with the new Pixels.
And like the new Pixels, some phones these days only come with a USB-C to USB-C cable. The included adapter doesn't help in that situation. Very few devices fall into that scenario, but it still could happen.
The original came with the adapter too? I don't remember that

It did indeed. I've used it frequently for USB OTG.
FYI, you cannot use a normal USB-A cable and the C-to-A adapter and connect your Pixel to a PC. It will not allow you to charge or connect to transfer files.
Really sucks, because I used this at work a lot with my original Pixel XL. Something changed with the new hardware and it prevents you from doing it. Luckily, I also have the original C to A cable that came with my XL.
Definitely a bummer for someone going from iPhone to Pixel 2. Now I have zero cables I can use to charge my new phone in my car. I left Apple because I was tired of being forced to buy extra things to do basic stuff so a little irked that I need to buy a special connector for car charging. Anyone have recommendations on a good cable that will actually work for both charging and data transfer?
They replaced it with the headphone cable.

There are heaps of good USB C to USB A cables out there. If you need one you can buy the google one from their store. Would have been nice to get one in the box, but I still have 3 lying around that I've used for previous type C phones.

So which third party USB C-A cables support the full 18W charging capability of the Pixel 2 besides the overpriced one from Google?
Edit: I found this one which supports USB 3 and up to 3A, if anyone is looking.

No USB A-C cable supports 3A charging unless it is out of spec. Google's A-C cable does not support 18W charging.

Do not use a 3A legacy cable to charge your phone, or you may risk damaging something.

Well the cable that I linked does have a 56kΩ pullup resistor, so it should adhere to the USB spec to prevent any damage.

Has anyone tested it to make sure it does though? I've seen several reviews from Nathan/Benson for cables that claim to have a proper resistor but don't.

That cable used to work with first pixel for fast charging but, does not work with pixel 2 I own 2 of them and was disappointed

I literally just got the cable today and noticed it's only saying charging. It should say "rapid charging" if fast charging is work correct?
Anyone confirm of a A-C cable that actually can fast charge?

I bought that and have 2 of them here. Nice cables! I can transfer data fine with them.

I did bring up Accubattery and it will only charge at 1a even with a 2.4a charger, which is disappointing.
I received my phone yesterday and found this to be very annoying. I have a few questions:
-Is the USB-C on this phone 3.0 or 3.1 spec or just 2.0? I just assumed all these new phones had 3.0+ speed
-According to google store, the cable that comes with this phone is 2.0 spec ($20 effin dollars?). Is there a 3.0 spec cable that will work?
-Are there any third party cables out there that will fast charge and have 3.0+ spec? (of course 3.0 is pointless if the phone itself maxes out at 2.0)

I picked up this one, it has not come in but it is USB-IF certified, so there should be no issues.

Hi all,
The longest charging cable sold on the OP site is 1.5M, but I would really like to get something longer.
Are third party high-speed USB-C cables able to support Dash if used with the official charger? Or is there some kind of non-standard wiring that limits me to official cables?
Any specific recommendations -- and warnings about false claims -- are welcomed.
Thanks!
This 6 foot extension cable has been verified on OnePlus forums to be compatible with dash charging:
