hey guy, I bought a pixel 2XL last 2 weeks and I didnot have fast charge adapter of google so i used adaptive fast charging of samsung. Is it OK? because when i took that phone, i checked it have 3200mAh and after two weeks, now it have 3150 mAh on battery. I want to know that pixel 2xl fast charging is possible with Samsung fast charger
If I recall correctly is not compatible, you may not charge at low speeds but I highly doubt it's using fast charge. The Pixel 2 XL uses USB C Power Delivery 2.0 for fast charging, most Samsung phones use propietary Qualcomm's Quick Charge technologies which are not compatible between them.
I've used a generic fast charge charging block with my 2XL and I get the "fastcharging" notification, so I'd presume it would work.
Don't ever use any other adapter that didn't support for Power Delivery. It will broke the charging port or some IC power, anything like that. Just saying. Better take 3rd party like anker or aukey that support PD.

Greetings,
Trying to find the charging time for the pixel c. Does it ship with the 60W type C charger on the google store? Or the 15 or the 22.5?
Whether it ships with 60W, will it charge at 60W?
34.2 WHr battery would be topped off in a half hour or so at 60W, just looking for any details those with the devices have. Not specifically interested in the generic amazon charger discussion just yet
In germany it gets shipped with the 15W one (5V at 3A) and it takes ages...but as I wanted to get some more external stuff, no harm done.
pixel c can use a USB PD charger (like the chromebook pixel charger) to charge faster at 24W (12V @ 2A). The only other USB PD charger I know of is the MacBook charger (29W), but not sure if it will fast charge the Pixel C as it uses non-standard profiles and I haven't been able to determine if it will also support standard PD profiles. I'm pretty sure it will charge the Pixel, but maybe not at the 24W speed.
This is the one I was curious about https://store.google.com/product/universal_type_c_60w_charger
Of course it states a lot of compatibility, but I can't quite figure out where it is intended to be used. If only the Chromebook Pixel uses 60W or if any of the other stuff like the Pixel C can go higher. Thanks for any advice
Even 15W should get the job done in a couple hours
The Pixel C help forum says "Charge the battery on your Pixel C by plugging a power adapter into the USB Type-C port on the left side of the tablet. We recommend using the charger that came with your Pixel C."
As the device comes with the 15w charger, this takes about 3.5 hours
I can't find any information on which Power Delivery Profiles it supports, I asked Google support if it will use anything other than Profile 1.
Google engineer Benson Leung has stated that with the 60w charger the pixel c will negotiate to a 12v, 2a charging speed

That's odd, 15W for 3.5 hours should charge a 52.5 Whr battery, but the c battery is smaller. At least the 60W charger will go to 24W, which should get the job done in less than two hours

From my testing, I see the charge cycle current skipping around as low as 1.8A and no higher than 2.8A, averaging at 2.2A. it could be the application, but this falls in line with my observed charge times.
Compared to my Nexus 6P which shows more stable current draw at ~2.8A to 3A.
I'd be interested to find what others are seeing for comparison
Hi everyone!
I have a car charger for my old phone, the OnePlus 3. But yesterday my Samsung Galaxy s8+ arrived and is now my daily driver .
My question is : Does a official OnePlus car charger (with dash charge) works for my Samsung Galaxy s8+? If so, does it damage the battery?
Kind Regards,
Pieter
I have tried mine with the old OnePlus dash charger and though it works, the charge speed is crazy slow. The phone was reporting that from about 40% it would take 5 hours to finish the charge.
Am guessing there is something propitiatory in the dash charger that is causing this. I dont use it on the S8 anymore, incase its damaging the battery somehow.

It won't damage the battery, but it also won't do fast charging as the Dash charging is proprietary and doesn't support Qualcomm's (also proprietary but much more widely used) Quick Charge 2 (or higher; QC is backwards compatible) that the S8/S8+ uses.
According to the car Dash Charger specs the standard (non-Dash) charge supports up to 5V at 2A, which is 10W. Compare this to the official Samsung charger's 9V at 1.67A (QC2), so provides 15W.

In theory then it should be able to charge the S8+ at two-thirds of the speed of the official charger, however it is possible there are other incompatibilities that slows it down - ie. the Dash charger won't provide the full 10W for some reason. A possibility might be the Dash charger cable, as from what I understand this is a bit different to a normal cable to support the Dash charging technology. Maybe try a high-quality standard USB and see if it charges any faster?
An aside: The S8/S8+ is the fact it can also fast charge over (the non-proprietary) USB Type C with 5V at 3A (also 15W). This isn't USB Power Delivery (USB-PD), just the 15W allowed by USB Type C, and since that can provide the full 15W the phone can use over QC2 there's no actual need for USB-PD - but most charges that support 5V at 3A are labelled as providing USB-PD and will work with the phone even if the phone don't use the 'PD' part of the spec.
All my cables home and car that fast charged my s8, won't fast charge my pixel XL 2. I don't get it and was wondering why. Only thing that works is obviously the oem charger and my Chromebook plus charger. Any ideas? Sucks to buy new stuff over again but want to make sure I get the right stuff if I buy new chargers.
Pixel uses Power delivery fast charging which sucks.
S8 uses Qualcomm quick charge. Your charger probably has QC but not PD
I am wondering about charging options for G7 and ask about two particular which I am most interested about.
1. Immediately when I got it I thought "cool, let's charge it a bit, let it sip a bit of a power from USB-C from the desktop", however there came the surprise No.1 - G7 is not fast charging, my 6P is (6P charges in 1 hour and something), G7 reported over 3 hours to charge.
How to fast charge the G7 from USB-C? I have a capable HW for that and Nexus 6P works that way.
2. I saw some mentions here that G7 supports 10W if not even 15W wireless charging, is that info verified? I am planning on buying a wireless charger (one at home, one at work), but I would like to know if there is pretty much any reason to buy 10 or even 15W chargers.

1. The desktop usually doesn't support fast charging. You need a phone charger that supports fast charging. The one included in the box will charge the phone for 1 and a half hours. You can of course buy a new one.
2. Any wireless charger will work but it won't charge fast. I tried Samsung's fast wireless charger but it charged the phone slowly. I would say, just use a cable if you're on a hurry and maybe a wireless charger when you're not using your phone.
But the thing is, Nexus 6P can, it is even stating it is fast charging via the very same USB-C port and cable, so naturally I am wondering why G7 is not.
Right now, G7 is being charged from USB-C just as long (considering what the estimation at the bottom of the screens is) I reckon would be charged via 5W wireless charger. I have dismissed the idea of more powerful charger, I don't need it, for that I don't mind it would be charging even over 3 hours.
And here's an example of how even though its a USB C port on the phone, not all features are implemented equally. Its either looking for some sort of resistance on the line in the cable or something else similar to that, as my Anker cables won't fast charge the G7 but will fast charge my Moto Z Play on my computer (which has the right port specs to support fast charge). If you look at the supplied cable with the G7, you'll notice that only one side of the C connector has contacts, and even then its a small amount of contacts that don't cover the whole side. more than likely the USB C cable you are using is fully built out so the phone is probably deciding that it won't quick charge when a fully spec'd C cable is used.
that's just my speculation
Nexus 6P doesn't support Qualcomm QC at all. LG G7 does.
Nexus 6P uses Quick Charge based on USB-C technology.
Different phones, different technology, different story.

Because Samsung wireless chargers use their own proprietary standard but not industry Qi which G7 is supported. G7 needs Qi capable fast wireless charging pad to enable 15W mode

Seems like Nexus 6P is capable of USB-C Power Delivery standard and G7 somehow is not. That's sad since I was hoping to buy one Anker or Aukey USB-C PD capable brick to charge G7 as fast as in can.

As for fast wireless chargers somebody should open a thread in https://forum.xda-developers.com/lg-g7-thinq/accessories about choosing fast wireless chargers. Like this one which is stated as supporting LG V30 with Qi EPP
Hi pixel owners.
I have 3 xl without it original charger, I used instead a Sony one (2.0) and Huawei 2.0 and dash charge (5v 4A)
All of them charges my phone about 1300mAh. The phone doesn't read it as a fast charge.
I used the same chargers and cable on other phones and it all works.
Should it be the original or what
Pixel line up charges over USB Power Delivery protocol. Our 3's XL charge up to 18W with the original charger.
I currently use the original one and a Motorola TurboPower from a Z2, which achieves 15W charging, not bad at all.
Haven't noticed changes between my cables.

In order to get fast charging you need a charger that supports Power Delivery (PD). It doesn't need to be a Google charger. There are many other choices out there. Same thing goes with a power bank. If you want to get fast charging, you need a power bank that supports PD *output*. There is also an "Accessories" forum here where chargers are discussed ad nauseum.
