The all-new Pixel 2 and Pixel 2 XL smartphones support fast charging which isn't exactly a new feature for a Pixel device. Though, this year Google has made it possible to charge new Pixel smartphones even faster with up to 27W USB-C charger.
Google's Benson Leung in a Google+ post confirmed that the new Pixel 2 and Pixel 2 XL will ship with 18W USB Type-C and PD (power delivery) power adapters. Leung also revealed that the new Pixel devices can support up to 27W charging from compliant PD chargers. "Also, a point about the software is that starting in Android Oreo, Pixel phones (including 2016 Pixel models and the Pixel 2 and Pixel 2 XL) now implements Type-C and PD support using the new Type-C Port Manager in the Linux kernel," he added.
The default 18W for USB-C Power is capable of delivering 7 hours of usage in just 15 minutes of charging. Pixel 2 and Pixel 2 XL users can expect to get even better usage time considering the 27W is even quicker. Currently, there are not many USB-C chargers with up to 27W power delivery but you can get Aukey from Amazon for roughly $25 (via 9to5google).
Considering the new Pixel smartphones support up to 27W USB-C chargers, we can expect some third-party accessory makers to come with their own version soon with "Made for Google" badge. Under the all-new Made for Google programme, third-party accessories will sport the "made for" badge on the packaging so that users know it has been certified to meet the company's compatibility standards.
