1, workmanship, materials are not the same. The wire diameter of the coil, the material of the partition, and so on. Some independent research and development, of course, to give you a research and development fee. Some copy others. It must be cheaper without research and development.
2, whether it is wired or wireless charging, the charger (board) heat naturally but one thing, however, in the case of wired charging, the phone and the charger will not be in direct contact, so generally not because the charger heat can not affect the phone body temperature; Reverse wirelessCharging can be different, in the long run, especially with poor quality charging board, will not have an impact on their own love machine inside can be difficult to say.
3, the charge efficiency is not high. Once the distance is a little far away, the efficiency of charging will be dramatically reduced, and a lot of time and resources need to be wasted to complete the charging, so the use is not meaningful. Safety issues in the charging process. High-power wireless charging equipment will produce a large amount of electromagnetic radiation, which will cause certain adverse effects on health, but also have interference effects on aircraft and communications. The first practical aspect.
4, price andCompatibility: Wireless charging devices are usually more expensive than wired chargers, and different brands of wireless chargers may not be compatible, and users need to purchase an adapter or charger.

Material,Technology and function are different. According to the market price research of 4-in-1 wireless charging, 4-in-1 wireless ranging from 30, 40 to 400, 500, up to ten times the difference, because the materials, technology and functions used are different, as well as sales channels, brand awareness, market competition and other factors, resulting in 4-in-1 wireless charging price differences.
