I've had a lot of USB wall chargers. I have the same number of USB-C to USB-C cables. Instead of buying several new chargers, I bought these adapters. As you can see from the photos they fit perfectly and are a fraction of the price of a new charger. And I still get "fast charging" with adapters plugged in.
