With the release of Apple's iPhone 8 and iPhone X, the wireless charging market has seen a spurt of growth. At present, the entire wireless charging market has increased by about 5-6 times before the release of Apple's new machine, and will continue to grow several times in 2018.

The main technical solutions for wireless charging include electromagnetic induction, magnetic resonance, radio waves and electric field coupling.
