Did you purchase a Nexus 6P or Nexus 5X? Then you should probably pick up a few USB Type-C chargers while they are available on Google Store, as you can rest assured that they will be fully compatible with both devices.
On the product description page, it states you can charge quickly with the chargers, but since we do not have one of these in-house, we don’t know specifically if they will charge “rapidly” on the 6P or 5X, but we have to assume so. The specs do not specify voltage and amps, but they are 15W.
They are not exactly cheap, either. For a standard charger, you are looking at $25. There is also a dual-port charger for $39.99.
Get them while you can.
