The speed of wireless charging is indeed slower than that of wired charging, mainly due to the relatively low energy transmission efficiency in the process of wireless charging, resulting in a slower charging speed. However, with the continuous progress of wireless charging technology, today's wireless chargers can also provide faster charging speeds. Some of the latest wireless chargers, such as those with fast charging technology, can achieve faster charging speeds. Therefore, although the speed of wireless charging is relatively slow, with the development of technology, more and more wireless chargers can also achieve a faster charging speed, providing users with a more convenient charging experience.
