USB Type-C to Type-C Spare Cable
Buying a phone with an entirely new port means you'll need more cables for the car, office, bedroom, bathroom and more. It can get expensive, so we'd recommend getting some of the 5-packs on Amazon.
That said, if you're getting the dual charger mentioned in our previous slide, grab an extra cable while you're at it. Not all Type-C cables are created the same, or even safe considering the power they put out. So get a certified one right from Google.
Google also has regular full-size USB to USB Type-C for older chargers or other car chargers and such. In case not all of your accessories take the smaller Type-C standard.
