Can You Charge An iPad With An iPhone Charger?

A very common question among Apple device users is whether you can use iPhone and iPad chargers interchangeably.

You can absolutely charge your iPad using an iPhone charger and vice versa. Apple designs its devices so that all devices with a lightning connection (iPhone, iPad, Airpods, iPod touch) can be charged using any charger that comes with an Apple device. 

The only difference is that the chargers for the various different Apple devices do not all have the same wattage. An iPad charger has more wattage than an iPhone charger does. Therefore if you use an iPhone charger to charge your iPad, it will take longer to charge than with an iPad charger.
