Is it feasible to use Lightning for charger?

If Apple wants to, it can use USB-C on the iPhone and continue to roll out USB-C to Lightning cables and Lightning-port chargers. But because devices must meet USB-PD compatibility requirements, you can charge your iPhone with accessories from other manufacturers, rather than sticking to Apple's first-party accessories. Apple doesn't have to, either.
