1, save time, do not need to pay attention to electricity, do not need to plug the phone line to play with the phone. And you don't need to leaveTime to unplug. 2, battery maintenance: lithium is characterized by use with charge, maintain use, not long-term overshoot, but put. If the phone is not idle, it will not overshoot, mainly overshoot. The use of wireless charging is basically between 80% and 100%. Great for battery maintenance.
2, wireless charging mobile phones on the market mainly use the principle of electromagnetic induction to achieve wireless charging. There is no interface between the charger and the phone. The phone has a built-in receiving coil, and the charger has a built-in sending coil. They use electromagnetic induction between them to charge the phone. No matter what brand of phone you buy, as long as it's compatibleCharging head wireless charging standard, basically can charge.
3, benefit one: reduce the loss. As we all know, when using wireless charging, you only need to connect the wireless charging board to the power supply, and then place the device that supports wireless charging on the wireless charging board. Although wireless charging still needs to be connected to the power supply, it can reduce the use of data lines and avoid a large amount of loss and waste of data lines, which is relatively an environmentally friendly charging method. Benefit 2: high adaptation rate.
4, the actual role of wireless charging is of course there, it can facilitate the charging process, directly put the phone on itWith Mag Safe magnetic wireless charging technology, the magnetic array placed around the wireless charging coil on the back of the body is optimized for quick alignment, and the magnets are automatically aligned with each other accurately, effectively improving the fit between the charger and the phone, supporting up to 15W of charging power.
3, iphone12Promax fast charge support 20w, support MagSafe wireless charging, power up to 15 watts, also support Qi wireless charging, power up to 5 watts. The Apple 12promax measures 160.8x71x4mm and weighs 226g. The Apple 12promax uses the A14 processor, which uses a 5nm process and increases the number of transistors by 40% to 11.8 billion.
4, W wired charging, 50W wireless charging and 20W reverse charging. iPhone12Promax: 20W wired charging, 15WMagSafe and 5WQi wireless charging.
5, iphone13promax: Apple A15, 6-core cpu, 5-core gpu, 4532mAh, 20w wired charging, 15wMagsafe wireless chargingElectricity, 5wQi wireless charging. iphone12promax: Apple A14, 3687mAh, 20w wired charging, 15wMagsafe wireless charging, 5wQi wireless charging.
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 additionThe magnetic field used by wireless charging technology is itself harmless to the human body.
In fact, it is certain to tell you that the harm of wireless charging to the human body is very small, almost negligible. This is like the Wi-Fi, mobile phones, TVS and other electronic products we usually use, and we do not exist between the transmitter and the receiver the radiation level is small, and the main frequency absorbed by the human body is inconsistent with the charging frequency, so we can not worry about the harm of wireless charging.
Conclusion: Wireless chargers do produce electromagnetic radiation, although the value is usually small, butThe possible cumulative effect should be vigilant. With the popularity of wireless charging technology, users are exposed to more and more radiation sources in daily life, such as mobile phones, computers, WiFi, etc., and long-term accumulation may have an impact on health. Wireless Charging Technology and controversy With the development of mobile Internet, the rise of wireless charging function has led to a discussion on electromagnetic radiation.
1, low efficiency: energy storage and delivery efficiency is less than real contact. chargingSlow speed: Due to low efficiency, the charging speed is slow at the same input power. Although wireless charging can be unplugged, the distance between the phone and the charger is very small. However, the electromagnetic energy loss is still not small, and the power received by the general mobile phone is about 75% of the power sent by the charger.
2, low charging efficiency Since it is for mobile phone charging, charging speed is of course the first, even if you can do the application of "wireless", but for the most basic requirements of charging speed can not be reached, then the experience will probably be a discount.
3, wireless charger voltageIt will not be too stable, and the voltage to be generated will be smaller with the distance of transmission, and the current will be small and the charging will be slow. But it's safer than some wires.
1, wireless charger is not harmful to the phone. The wireless charger uses electromagnetic induction technology, which transmits energy by using a magnetic field generated between coils, coupling the current from the charging disc to the mobile phone battery, for the battery, its charging process is no different from that of an ordinary wired charger.
2,Wireless charger 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.
3, no harm to mobile phones. Wireless charger uses the latest wireless charging technology, by using the alternating magnetic field generated between the coils, the transmission of electrical energy, inductive coupling technology will become a bridge connecting the charging base station and equipment.
4, is the wireless charger damaged to the phone? No wireless charging technology will not only not damage the phone but also extend the service life of the phone charging interface. Traditional chargers work differentlyWireless charging uses electromagnetic induction technology to transmit energy through the magnetic field generated by the coil, and there is no difference between the two charging methods for mobile phone batteries. Wireless charging introduction: Wireless charging is completely harmless to the human body, there will be no radiation and the like.
