Method 2: Choose matched power adaptor and USB cable

The official charger head and USB cable are recommended first if your iPhone won't fast charge. Adapter's output power must be higher than the need of iPhone, so that it can charge out of load. In addition, the USB cable and charger head must support fast charging simultaneously. A normal USB cable can be used to charge even if it's not matched by the charger head, but the speed might be affected due to it not supported with fast charging. Therefore, it's better to use the fast charger from Apple. If you are using a USB cable or charger head from another manufacturer, you will need to check them to see if they match.
