No strong radiation, no effect on the human body! The main principle is: wireless chargingThere are electromagnetic induction, magnetic resonance, electric field coupling and radio wave transmission, wireless charging of mobile phones mostly uses the principle of electromagnetic induction.
For the human body: wireless charging technology is safe and harmless to the human body. The resonance principle used by wireless charging is magnetic field resonance, which is transmitted only between coils resonating at the same frequency, and other devices cannot accept the band, in addition, the magnetic field used by wireless charging technology is itself harmless to the human body.
There is a little radiation, as long as the person is not between the transmitter and the receiver, the radiation level is very small, and the charging frequency is not consistent with the frequency of the main absorption of the human body,The harm is negligible.
So we don't have to worry about the harm of wireless charging. Of course, it may not be harmful to the human body, but what about our mobile phones? In fact, if you have used wireless charging people may find that the heat dissipation of the mobile phone is not ideal in the process of use, sometimes the mobile phone will heat or even hot water after washing, so when we choose the wireless charger, we should choose regular products to have quality assurance, and the damage to the mobile phone can be reduced to a minimum.
With the development of the mobile Internet, the rise of wireless charging has led to discussions about electromagnetic radiationThere are many electrical appliances in it, such as TV, air conditioner, refrigerator, washing machine, computer and so on.
2, WiFi has no effect on pregnant women, it can affect only the skin surface, as long as it is not close to the body, its impact is completely negligible, so it has little impact on pregnant women.
3, in fact, pregnant women can normally use Wifi, expectant mothers do not have to connect to Wifi as a big problem. In daily life, there are more devices than Wifi radiation, but for the sake of health, expectant mothers try not to put their mobile phones connected to Wifi on the pillow during the dayThere is no problem with use.
4, problem analysis: Hello, under normal circumstances, in the early pregnancy, due to the critical period of differentiation and development of various tissues and organs of the embryo, we should pay attention to avoid radiation as far as possible, in the middle and late pregnancy, the general impact is relatively reduced. Suggestions: Your situation, the current pregnancy of 7 months, consider the impact to reduce, pay more attention to observation, pay attention to late pregnancy health care, reasonable diet, do a good job of inspection.
1, mobile phone wireless charging benefits have convenience, flexibility, protectionProtection interface, the harm is low charging efficiency, slow charging speed, high cost. Benefits Convenience: Wireless charging of mobile phones eliminates the hassle of using a charging cable. Users only need to place the phone on the charging dock, without plugging or unplugging the charging cable, to start charging. This makes the charging process easier and faster. Flexibility: Wireless charging eliminates the need for a specific charging cable.
2, cable charging. In the case of the same charging time, the power of the commonly used wired battery charger is 93% after charging, and the power of the wireless charger is 88% after charging. Obviously, there is still a gap in the charging efficiency of wireless chargersThere is still room for further improvement in technology.
3, the wireless charger charging transmission distance is short, the effective transmission distance is usually within 10mm. (2) The power is relatively low, the current Qi standard stipulates that the power is 5w, 5w, 10w and 15w power, which is still too low compared with the high-power chargers such as 18w and 48w, resulting in the wireless charger charging the mobile phone slowly.
4, some Samsung mobile phones support wireless charging function, to achieve this function requires a separate charging kit, wireless charging and wired charging effect is the same, only wireless chargingThe interval is relatively long and has no effect on the phone.
No harm. On the contrary, it can also protect people from electric shock, and it can also waterproof and extinguish arc. The frequency of use is also relatively low. Not harmful to humans. withMany products are shielded, so the radiation is very small. There's no harm.
Under normal circumstances will not harm the mobile phone, wireless charging now the working frequency is done below 1M, so the signal of the mobile phone will not have an impact. Wireless charging has no effect on mobile phone battery life, and wired charging is basically the same, but the rate is lower, but the wireless charger conversion rate is still high, more energy saving.
Generally speaking, wireless chargers do not harm mobile phones. The wireless charger uses electromagnetic induction technology, which is transmitted by using magnetic fields generated between coilsTo send energy, it couples the current from the charging disc to the mobile phone battery, for the battery, its charging process is no different from the ordinary wired charger.
