Charge your iPhone 12 extra quickly with a powerful Power Delivery charger. The iPhone 12 doesn't include a charger, but it does come with a USB-C to Lighting fast charging cable. This cable works with fast Power Delivery chargers, but not with the 5-watt charger that old iPhone models include by default. An iPhone fast charger is about 3 times faster than a 5-watt charger. After half an hour of charging, the battery is back up to 50%. You don't necessarily need the original Apple charger for this. Choose a Power Delivery charger with at least 18 watts of power to charge your iPhone 12 at maximum speed.
