You can use the Mac power adapter. It will not harm your iPhone. The iPhone will not draw more power than it is designed to. Also see the following from Charge your iPhone with an iPad or Mac notebook power adapter - Apple Support
You can use Apple USB power adapters for iPad and Mac notebooks to charge iPhone, iPod, Apple Watch, AirPods, and other Apple products.
