Wifi Mobile charging
PROS AND CONS OF WIRELESS CHARGING SYSTEM
Advantages
A stronger sense of science and technology
Wired charging requires dragging a long data cable, which is ugly and has no sense of technology at all.
More convenient to use.
Wireless charging mobile phones on the market mainly use the principle of electromagnetic induction to achieve wireless charging. They charge electricity into the mobile phone through electromagnetic induction, No matter what brand of mobile phone you buy, as long as it is compatible with the wireless charging standard of the charging head, it can basically be charged.
The interface durability is better
Because mobile phone wireless charging does not require frequent plugging and unplugging of the charging cable, the wear and tear of the data interface of the mobile phone will be reduced a lot.
Disadvantages
The distance is too small, just a transition technology
Because the magnetic field decays quickly in the air, the wireless charging technology of current mobile phones generally has a very small distance, and the effective charging distance is generally only 3-8 mm.
Can't play with the phone while charging
Most of the mobile phone wireless chargers on the market are placed flat, and the mobile phone must be close to the charger. In this charging position, it is basically impossible to play with a mobile phone, and you have to use a headset to connect and listen to the phone.
There is electromagnetic radiation
Wireless charging of mobile phones is carried out by electromagnetic induction, so the charger generates electromagnetic waves all the time. This electromagnetic wave is generally in the frequency range of tens to hundreds of MHz. Although it may not cause much harm to the human body, it is still much more harmful than wired charging.
The price is more expensive
Compared with wired charging for mobile phone wireless charging, both the charging head and the mobile phone need to add a charging coil and related protection circuits. At the same time, a high-frequency wave circuit is required to meet electromagnetic compatibility, so the overall price is higher than that of traditional wired charging.
