Unfortunately, wireless charging is not available on the iPad4. Although it is already a very smart product, its charging method still needs to rely on traditional wired charging method. That means you have to use the original Apple charger, plug it into the charging mouth of the iPad4, and plug the other end into a power outlet. Of course, you can choose to use the appropriate charging cable to increase the length of the charging cable.
There are already a few wireless chargers available for the iPad, but they generally require an additional receiver to work properly. So while the wireless charging option is convenient, it also requires extra accessories for older devices like the iPad4.
All iPad models do not support wireless charging.
