So I've been testing my chargers at the most basic level with every day tools.
Today I got my Kill-a-Watt and plugged in the motorola turbo 30 just to see what it reported. Then I plugged in the stock Pixel XL charger and it said the same, which was strange since the Motorola Turbo 30 is supposed to be 5V 3A usb type c, which would be 15watts, but it said it was pulling 18watts just like Pixel charger was reporting.
So I alternated and switched cables, notice that the Pixel charger would report only pulling 12-15watts. So I reverted to cable I first tried, Pixel cable, but it still reported 12-15watts... I was like humm what happened. I plugged the Motorola turbo 30 again, same 11-14wats..
So I restart the phone, 18.5-18.9watts on motorola turbo 30 and same on Pixel charger. Started switching cables again, same 18.5-18.9watts.
After a short time it switches back down to 14-15watts
Anyone experience this?
My Pixel C tablet does not start to charge immediately when I plug it in to any charger. It registers that it is plugged in straight away, the battery icon changes straight away to the icon with a lightning bolt and the Ampere app registers as being plugged in, but it does not start charging. The battery information screen says 'Not charging' and ampere says the battery is still discharging. After about a minute this usually changes and the tablet does start charging, but a couple of times it has not charged at all while registering that it has been plugged in for half an hour.
This happened with my brand new tablet, so I returned it and the second and third replacements have been exactly the same. This happens using different chargers and in different locations (I have tried different sockets around my house and at work).
Has anyone else experienced this? I am about to return my third tablet for a refund as I don't want such an expensive device that I can't trust is going to charge.

Mine does this. I just chalked it up to new USB C charging standard and it calculating what to pump in to the battery before it begins.

Has yours ever not started charging eventually? That's what made me call Google support and the four people I have spoken to there all say it not charging immediately sounds like a fault.

It has always begun charging. Hell, maybe mines faulty too, but I never thought of that.

Mine does this, I wondered if it was a USB C thing too. when I plug it in the charging icon appears immediately but Ampere shows plugged in/discharging, the discharge rate starts low at approx 300mAh and over about 30 seconds rises (drops?) to, for example 1750mAh before flipping to displaying charge at 1750mAh. The final plugged in/discharge rate always matches the initial charge rate measured.
I usually charge using an Anker multi port charger and USB A to C cable. it behaves the same but with higher numbers with the Google supplied charger.
I am curious to know if USB C negotiating its best charge rate somehow fools Ampere?
I just bought a Pixel C and I am using it with a generic 5V /2A charger and a Dash usb C cable. It does the exact same thing that the OP described. I have to plug the USB end of the cable into the charger once or twice, before it starts charging. If I just plug the tablet in normally the lightning symbol appears and it does not start charging.
USC Type c takes 10 secs to negotiate. I would not use other chargers or cables. Stick with stock or known tested working ones. Refer to this spreadsheet
https://docs.google.com/spreadsheets/d/1vnpEXfo2HCGADdd9G2x9dMDWqENiY2kgBJUu29f_TX8/pubhtml
Remember ampere is not accurate and is only a best guesstimate. I recommend using current monitor in conjunction.
Becareful using generic cables and chargers risking frying your devices. If the cable is not made programmed correctly missing emarker or same for charger, USB Ttype C Power Delivery cannot not negotiate correctly. If it's missing altogether it may overcharge..
I've found the Pixel C to be a little picky with its chargers but the only really big disappointment was with the Pixel phone charger. That charger is supposed to support Power Delivery and can charge faster than the Pixel C charger can so I naturally plugged it into the tablet and it is useless! It connects and disconnects continuously so it never accomplishes any charging and the screen will not stay off. You'd think a charger and a device designed by the same company, advertising the same USB charging standard, sharing a marketing name, would work together!

You might have a defective Pixel charger or cable, it has been known to happen. That is why people have gotten replacements.
On that note consider that the Pixel comes with the same charger as the XL, but it doesn't charge at any faster rate than 15W with it's own charger..

Yes, I have heard that the Pixel-xs doesn't make use of the higher voltage (9v, I think?) charging option, but I was hoping the Pixel C would. It is known to work with other higher power chargers. Maybe I'll call up the old Google and see if my charger is bunk. Even if it is no faster it shouldn't cyclically fail to auto negotiate like it does.

The Pixel C is 5V/3A 9V/2.67 12V/2A. I use both the Xentris/verizon USB-C/QC ($9-40) and Targus 45W ($30-55) chargers, both charge my Pixel C at 24W 12V/2A. It's great.
I have just purchased the Belkin charger cable that is on the Google list. The tablet's behavior is still hit and miss on the 10V/2A chargers that I have. I am using the Samsung S2 charger (should be plenty good quality). I am not even looking for fast charging or anything, just consistent behavior. If I plug in the usb C end of the cable ampere starts to show a discharge rate of like -500 mA and it does not start charging. The built in battery indicator says USB Charger = not charging. This happens about 7 times out of ten. In the other 3 cases it starts charging when the USB C end is plugged into the tablet. If I look at Ampere and see that is does not charge for like a minute, then I unplug the USB 2.0 end of the cable from the charger, re-insert it and voila it starts drawing 2000 mA immediately. I have tried 3 different chargers so far and the behavior has always been the same.

The Pixel C uses USB Type C Power Delivery 5V/3A 9V/2.67A 12/2A. 24W max
Ampere app is rather useless and just for reference. (note I use it often) Try Current Monitor. Regardless both rather useless, since the Pixel C doesn't negotiate faster charger until after the screen turns off. So while you have the screen on looking at Ampere/Current Monitor, you're gonna get a fluctuating reading that doesn't make sense. I use a kill-a-watt to see the wattage being pulled.
I am able to get a solid consistent 15W charge out of the stock OEM charger. I can get anywhere from 15W (screen on) with my Xentris/verizon and Targus 45W chargers and 24W (screen off).
Also note USB-c is not consistent, it negotiates different levels and it always changing depending on several conditions, like battery level, temperature and if screen is on at the time.
I've attached some results using LG V10 OEM Charger, Samsung Fast Adaptive Charger and Asus Nexus 7 charger with USB A to C with 56k ohm pullup resistor connected to the Kill-A-Watt for reference.
My Pixel XL would change with older USB ports and my portable battery. It would show that it was slow charging but it would charge.
The Pixel 2 XL shows a charging icon (nothing about being slow) but it will not charge the battery. Hours later the battery percentage actually goes down a little.
Only charging from the wall seems to work.
seeing this with chargers that are 1A and lower - haven't tested between 1A and 2A yet
3A and above (stock charger) is fine

Well I’m testing it out with two Pixel 2 XLs this morning because of staining issue on the first one and the dead touch edge this which I guess will be fixed in an update but they sent me a new one anyway.
So:
The new Pixel 2 XL has less stain marks on the white back.
The screen still turns blue as I ever so slightly tilt it but screen is whiter when dead on as the old one is a little peach-ish. That is with both screens at the same brightness and with the same color profile.
The new Pixel 2 XL is also charging with the same portable Duracell charger that the old one can’t use. Even over night with the charging icon on the old Pixel 2 XL would not charge and the Duracell charger would still showed full like nothing happened.
I’d just get my money back if they did not have my (in perfect condition) Pixel XL for trade in that they still have not processed yet and I can’t wait to see if I’m one of the ones they try rob by saying it was not reset or not as described etc.
Got this from good old off-shore support.
Furthermore, please note that it's recommended to use the original charger that was supplied with the phone for best results. Also, the 3rd party chargers may cause damages to your device.
The USB cables and chargers seem ok. They all work with my Nexus and Pixel XL and they work with the replacement Pixel 2 XL. I was just wondering if that was yet another known issue?
I’ll be sending the older Pixel 2 XL back as soon as I move everything over to the new one. While they both have poor touch sensitivity at the edge of the screen at least the new one will charge from low amp USB ports. As Google has my old Pixel XL I don’t have an option.
Will the poor touch response at the edges be fixed in firmware? Some on-line are saying it will be but I just got the 8.1 update and its still hard to use keys and buttons at the very edge of the screen.
I kinda wish I could just get my old Pixel (1) XL back. Google and LG really let us down this time.
I noticed this when I tried to charge my Pixel 2XL in my car using a micro USB to C adapter, which worked fine with my Nexus 6P. However, using a USB C to A works fine. Doesn't charge quite as fast as using original, but it's pretty good. Same with my portable charger. Luckily I won't have to use it often, but now I know I can, without having to buy a new charger.
can we get this to XDA or AP so this can be investigated properly?
if we can't use any old portable battery chargers or plug into our auto via USB and charge this is a serious issue
I have tried three different wireless charge receivers with my Pixel 2 XL. I get the same issue with each of them.. when trying to charge, the battery indicator drops, not raises. My charger indicates that it is charging, the phone shows charging, but it is draining the battery.
Any thoughts? Has anyone successfully added this functionality to the Pixel 2 XL?

The Pixel doesn't support wireless charging natively. You'd need a new case like a Mophie to do it.
That is why I bought a wireless receiver. Same one I used on my V20. Which worked fine. It provides a charge current to the USB C plug.

I have a charging problem with my Pixel 2 XL.
It will not charge with any wall charger or car charger.
I have one of thoes portable battery banks, and it charges the phone just fine. It also charges when plugged into a computer.
Anyone have any idea why this is happening?

I have an issue where sometimes the stock charger (as well as a replacement) will very often only charge my phone when plugged in one way. All other chargers are fine.
Well I went in the settings, did a factory reset. Still had the problem.
Then I downloaded and flashed the factory image with data wipe and phone charges like it supposed to now.
I had a problem with this as well.. it will charge on anything that is low amp... It won't connect to computer to transfer anything but will charge slowly.. I had mine replaced and they said it was the charging port..
