In general, charging the iPad with an officially recommended charger or a charger that meets the relevant power requirements will not harm the iPad.
For example, the typical charger for the iPad is 10W or 12W. These chargers can safely charge your iPad without causing damage to the device. Chargers with less than 10W May take too long to charge, or fail to fully charge the battery. The use of a power higher than 12W charger, although it can be charged normally, but its charging speed will not be significantly improved, but may increase the heat generated during charging, which has an impact on battery life. Similarly, the Xiaomi 65W gallium nitride charger can also charge ipads and iphones without damaging the battery. However, when using such non-original chargers, be sure to pay attention to whether the quality and power of the charger meet official requirements to prevent damage to the equipment. If there is any doubt, it is recommended to use the original charger.
