Thank you very much for viewing. This is one 20W USB-TypeC power adapter. Other quantity sets are also available, so please check my other listings. This adapter can charge at 20W. Conventional adapters are 5W, allowing for fast charging. Charging is so fast that you won't go back once you've used it! It supports fast charging for all devices from the latest models to iPhone 5 and later. The material and size are the same as the genuine product, but it is not an Apple genuine product, so there is no Apple mark. One 20W PD fast charger iPhone USB Type-C outlet
