Google Pixel 2 will offer even faster charge speeds with a 27W adapter [Update: Actually...]

Updated on October 6, 2017 – Well, looks like the Pixel 2 won't charge faster after all. Google released a statement after we published this post to clarify that, while the USB port on the Pixel 2/Pixel 2 XL is technically capable of supporting 27W charging, the circuitry and battery itself are not. In other words, you'll be limited to 18W charge speeds no matter what. We apologize for the confusion.

The Pixel 2 and Pixel 2 XL bring a lot of goodies to the table, but while these two phones get a lot right, one feature that's noticeably absent from the handsets is wireless charging. Google is hoping to make up for this with cabled fast-charging, and thanks to the comment from one Googler, you'll be able to top up the Pixel 2 even faster than we initially thought.

Out of the box, the Pixel 2 and Pixel 2 XL will come with an 18W USB-C power adapter that allows for seven hours of battery life in just 15 minutes. That's not a small number by any means, but if you manage to get your hands on a compliant power delivery charger, you'll be able to use a power adapter up to 27W with the Pixel 2 and Pixel 2 XL.

Faster charge rates than 7 hours in 15 minutes? Count us interested.

A jump from 18W to 27W is quite substantial, and this means you'll be able to get even faster charging speeds than what Google offers by default. Not including the most powerful charger might seem like a cash-grab from the company, but you'll still be able to get insanely fast top-up speeds with the regular 18W adapter. However, if you want even faster rates, you have that option available to you. (Fear not, this isn't like what Apple is doing with its latest batch of iPhones).

If you want to pick up a 27W adapter while waiting for your Pixel 2 preorder to arrive, make sure that you purchase one that's compliant for 27W power delivery and from a brand that you trust to ensure you don't do any damage to your shiny new device.

  • So, I'm guessing that means neither of these are Qualcomm Quick Charge 3.0 compatible and to have "fast charging" you'll need specific adaptors from Google? If you don't use those, what's the fallback?
  • longer battery life :)
  • It won't harm the battery
  • They're not. Google is using a non-propriety fast charging method - USB Power Delivery. Sounds like 9V 3A (27W) charging is enabled vs. the 9V 2A (18W) max that the previous gen had. The fallback depends on the charger. USB-C with USB-PD usually uses 5V 3A (15W). USB-A to USB-C without a proprietary "fast charging" method I think tops out at 5V 2.4A (12W).
  • Great response!!!!
  • No need for specific adapters from Google. Like Ry said, they're using Power Delivery which is a non-proprietary fast charging standard. As long as the charger you're using supports PD, you're good to go. Quick Charge is proprietary to Qualcomm chips, therefore it can't ever be universal like PD can.
  • Yup. As Ry points out, you've got things backwards. Qualcomm Quick Charge is the proprietary method, Google are about the only company doing it right.
  • Motorola uses 5V 3A (15W) as their "TurboPower Charging" for their USB fast charging method on their USB-C phones. Although some of their USB-C phones like the Moto Z Force Droid support a higher 5V 5.7A (28.5W) profile, which may not be a specific USB-PD profile, for even faster charging.
  • The Moto Z Droid comes with a 30W adapter.
  • They rounded up since TurboPower 30 sounds better than TurboPower 28.5.
  • Moto is PD compliant with some of their devices? I thought they had something proprietary in place, but the last Motorola phone I owned was an Atrix.
  • Micro USB devices used Qualcomm Quick Charge branded as TurboPower.
  • No Qualcomm QC but USB pd, same as last year's, except these will accept up to 27W.
    It's the opposite of needing anything from Google in particular. Any USB pd compan compliant charger that supplies at least 27W will work.
  • There should be one in the box...
  • It'll ship with an 18W charger, not a 27W charger though.
  • I know, I meant the 27 watt charger should be in the box.
  • Nope. People reading Android blogs know about using a charger that's at the upper limit of what the device can handle. Hopefully, they also know how to be safe with it. A 27 watt charger will catch fire faster than an 18 watt charger if you do something dumb like cover it with dirty clothes or use it with a split power cord. People really do this. Also, they could sell a version with it in the box with a price adjustment, but that means even more inventory management and we all know how Google sucks at that. I already put testing third-party chargers on my Pixel 2 todo list. We'll find a nice cheap one somewhere. :)
  • In my opinion, if it can't safely draw 3 Amos at 9 Volts, it shouldn't be able to, they should have capped it at 2A. Basically as I see it, either charging at 27 Watts is considered safe and the charger should be in the box. Or it's considered unsafe and the phone shouldn't do it.
  • Yep.
  • One of the many reasons I bought the essential phone.
  • Less features and a worse camera?? How does that make sense. Not to mention the fact that none of this was known when you bought the Essential phone. I think you just wanted to tell everyone you bought the Essential, we aren't impressed, by all accounts it kind of sucks.
  • I didn't pre-order the phone and I don't understand all the hate towards it. I know this is hard for you to believe, but it's a great phone just like many other phones on the market. And I was specifically talking about changing. Let's not turn this into something more.
  • Huh? You bought the essential because it charged faster?
  • That was one of the reasons, yes.
  • But how fast does it charge with the headphone and charge adapter? USBC can't negotiate a faster charge rate than .5A when the data pins are used for audio. Maybe that expensive adapter has some magic to negotiate higher current.
  • That's why you listen to BT headphones for the hour you are charging your phone.
  • Not in my two vehicles that do not have BT streaming support. No big deal for commute, but if traveling with display on for maps then need to be plugged in. And no I don't want some extra BT thing to turn on/off etc. I cancelled my order because I decided the headphone jack is a big letdown for the price of the XL.
  • Wireless charging will come in next year!
  • Probably, now that Apple has picked it up I expect Google to re-introduce it.
  • Yes, a year after Apple ditched the headphone jack, Google followed along. Apple has Qi this year. Google will next year. Actually looking forward to that. Should have done it this year.
  • So the rapid charging brick doesn't come with the 650 to 950 Pixel devices? If I wanted to get ripped off I would just by an iPhone :(
  • An 18W PD rapid charger does come with all of the Pixel devices. This article is just saying that if you use a more powerful PD charger, the phone will charge even faster.
  • Now the bigger question for 650 to 950 why not include the best possible charging experience? QI charging is out. Headphone jack is out. Expandable storage is out. Sure the speedy updates is compelling to the Android nerds, but the average consumer wouldn't really care. The whole point of the pixel program is to be a compelling product for all, not the few Android nerds that blow a load every time Google releases a new device. :)
  • Kudos! I had the same reaction when the pixel 2 came out. It's just a glorified Google iPhone but just more of a rip off. Hahahahah
  • Does anyone know the speeds of the Nintendo Switch power adapter? And if it is standard compliant? Safe to use on a phone? I figure that many have a Switch and can use the adapter.
  • As I recall, the switch has a 39W charger which outputs between 5-15V at 2.6A, but I'm not sure if it is within the USB-PD spec... I wonder if Benson tested one... Might look into it, I'll report back if I find anything. Winning I remember lol.
  • After a little research (and cooking and eating dinner :p) it appears the switch and it's adapter are USB-PD compliant, but it can only deliver either 5V at 1.5A (up to 7.5W) or 15V at 2.6A (up to 39W). So the short answer is no, it'll only charge the pixel 2 at 7.5W.
  • Well dang.
    Thanks a lot.
  • I can't stand how they measure charge in hours of use. What's the percentage!
  • Agreed. 7 hrs of what percentage.
  • I was going to comment the same thing. Maybe a mAh amount in a timeframe. Everyone's usage is so different, 'hours' is so subjective. I know I've never hit 3 hours of SOT with my 6P my Moto X or Galaxy Nexus, though there were always people that could sip out 4 or 5 hours from these phones.
  • Nor is mAh necessarily an entirely useful figure in all cases, as even with usage aside there are numerous hardware configurations. There isn't really a useful comparative measure when phones vary in their hardware by any reasonable amount. mAh might only be useful when comparing minor upgrades in a series of the same phone.
  • Watt hours (or mW hours) are universal. http://thewirecutter.com/blog/watts-in-a-name-why-were-using-watt-hours-...
  • If they used percentage it would have no marketing appeal whatsoever, but I totally agree that stating hours is horse ****.
  • I'm not so much concerned about "how much faster" the phone charges as I am about compatibility with the numerous chargers that I already own. I understand that the charger in the box is the best one to use. However; I don't want to buy two more car chargers, a charger for my office, backpack, suitcase, bedside, etc., specifically for the Pixel 2 XL. And yes, I understand that the ones I already own will work - just slower. It seems to me that the "best" method is the one employed by OnePlus in terms of speed and protecting the battery for the long haul. But again, it's a proprietary charger that I'd have to buy multiples of. Since the 2 XL is a LG phone, I'm really surprised they didn't stick with the more "standard" (in the US) Quick Charge. In that case, QC 3.0.
  • Yea except it's not proprietary and you can mix and match usb-c adapters. It's just needs to meets the PD standard up to 27w to get the higher charging speeds. it's a Qualcomm chip and Qualcomm sets the QC 3.0 standard. So the Pixel would use QC 3.0 for charging. Correct me if i'm wrong.
  • The difference between 18 W and 27 W will probably be only a few minutes (I'm guessing 4). You'll get to decide if it's worthwhile to spend more money and probably have a bigger and heavier brick just to save a few minutes.
  • Will the Pixel 2 charge at it's full potential using the PixelBook 45w charger? They said at the event that you can use it for both but they never mentioned faster charging.
  • My Asus C302 Chromebook charger is rated at a maximum of 45W, but has a table on the label detailing the various different voltages and wattages it can output - 5V/9V/20V etc. I expect the Pixelbook charger will be the same.
  • Google Uses strict USB standards, which means USB PD, not the nonstandard QC2 or QC3 over USB-C. Amazon ( if you use AC's link) shows some true USB PD 27W chargers, and some that claim to be 27W but don't deliver the full rating to a single port, and others that are playing QC2 and QC3 games, so watch your step. Hopefully Benson Leung and Nathan K. will review some chargers for us (or USB IF certified 27W chargers will start showing up) so we'll have some units we know we can trust. Note that you cannot simply choose a USB-C charger that has 9V @ 3A. The USB PD spec insists that 27W chargers also offer 15V. If they don't, negotiation will NOT choose the 9V @ 3A option.
  • I'm just checking the USBC charger that comes with the Samsung Chromebook Plus. It says on it - 15V=2A; 9V=3A; 5V=3A. It doesn't say what the wattage is but if W=VxA then it should be rated at 30W. I guess this would charge the Pixel faster then?
  • pity the battery life sucks.I am sick and tired of running out of juice overnight with my 6P Android 8 including recent update and it seems nothing has changed over the years phones should last at least 2 days but this crappy idea that phones have to be charged every day is the biggest problem with mobile devices .
  • You need to replace the battery. It's easy (check Reddit.) I love my 6p again!
  • The only phones I've seen last 2 days outside of testing conditions are phones with 3000+ mah batteries used by people who keep them in their pocket in case of emergency. It's 2017, people have smart watches or fitness trackers communicating with their phones 24/7 and all these great features on their phone that use battery that they actually want to use. I'm good with it if it lasts all day, but fast charging has pretty much negated any anxiety about battery drain for me, as even my 3-year-old Nexus 6 can be charged significantly in the 15 minutes it takes me to get home using less effective charging technology than the new Pixels use. Battery life isn't near the problem it was before fast charging.
  • Aww.
  • Please fix the app so it updates with changed info like this.
  • Where is the update? No showing in the app
  • 7 hours of battery life with 15 mins charge? Haha u mean Standby time???
  • Wonder how this compares to Dash Charge.
  • DASH charges at nearly 20W, and uses a higher amperage rating like Power Delivery for phones. The difference is that DASH is very proprietary (doesn’t work with other phones minus Oppo/OnePlus phones) and that the heat-producing circuitry is moved to the wallwart, meaning that it stays cool.
  • Nevermind that.
    Cheers.
  • Is a 18W charger the same as a Quick Charge charger? I have a Nexus 6 w/ 2 quick charge (1.0? 2.0?) chargers. Will those charge my (hopefully soon) new Pixel 2 XL?
