With a powerful Power Delivery charger, you charge your iPhone 12 extra fast. The iPhone 12 doesn't include a charger, only a USB-C to Lightning fast charging cable. This cable fits in the fast Power Delivery chargers, but not in the 5W charger that is included with older iPhone models by default. An iPhone fast charger is about 3 times faster than a 5W charger. After half an hour of charging, your battery is back up to 50%. You don't need the original Apple charger for this. Just choose a Power Delivery charger with at least 20W of power to charge your iPhone 12 at maximum speed.
