The current wireless charging has not been able to achieve true wireless charging anytime and anywhere. Instead, the mobile phone is placed on a charger that can be charged wirelessly and conducts electricity through electromagnetic waves, thereby adding power to the mobile phone.
The charging loss rate of wireless charging is currently relatively high, around 30%. Take an Apple mobile phone as an example. One hour of wireless charging is equivalent to 15 minutes of wired charging.
Of course it is needed. The most suitable scenario is in an office environment. Put the phone directly on the wireless charging stand. To read the information, you can reach it in front of you with your hand stretched out, so you don’t need to unplug and plug it in every time. The principle of wireless charging is electromagnetic induction, which is a physical phenomenon in which electricity and magnetism can be transformed into each other under certain conditions. At present, the mobile phone wireless charging base converts electricity into a magnetic field, and the wireless charging coil on the mobile phone can convert the magnetism into electricity to supplement the power of the mobile phone.
