Wireless fast charge is a wireless charging technologyThe combination of fast charging technology, the mainstream models on the market now support wireless fast charging technology. Wireless fast charging mobile phones are Xiaomi Huawei P40, Mate30, Mate30 pro and so on. Wireless charging technology Because the charger and the electrical device transmit energy by magnetic field, the two are not connected by wires, so the charger and the electrical device can be no conductive contact exposed.
In general, wireless fast charge is a wireless charging method based on magnetic resonance, electromagnetic induction and other technologies, which eliminates the tedious operation of wired charging and brings users a more convenient and efficient charging experience. Its wide applicationWith the continuous technological development, it indicates that wireless fast charging will become the mainstream way of charging electronic devices in the future.
In simple terms, the so-called wireless charging is that it can be charged without touching the wire, and the mobile phone that supports wireless charging can be put and charged on the wireless charger. Wireless charging methods include electromagnetic induction, magnetic resonance, electric field coupling and radio wave transmission, etc. Wireless charging of mobile phones mostly uses the principle of electromagnetic induction.
Wireless fast charge is the use of electromagnetic induction principle, there is a coil in the sending and receiving end, and the sending end coil is connected to the wired power supply to generate electromagnetic signals.The receiving coil induces the electromagnetic signal of the sending end to generate a current to charge the battery, which can be simply understood as a transformer without a magnetic core. Compared with wired, wireless charging has less loss to the battery, and wireless charging technology is more convenient and has lower charging heat.
w Wireless fast charge refers to the wireless fast charge technology power up to 50W. The 50W wireless charger can almost complete the entire charging process of the 4500mAh large-capacity battery in less than 50 minutes. That's about the same speed as most wired fast charges today.
wmax wireless fast charge Yes NoneRate. Charging time of more than 2 hours of wireless fast charge, not as fast as the wired fast charge of 1 hour and 30 minutes, is not fast charge. Unexpectedly, the wireless fast charging efficiency of 60% when the 18W is charged for 2 and a half hours. 2, in general, the conversion efficiency of car wireless chargers is limited, but by reasonable choice of chargers, we can improve the situation. Although the speed of wireless fast charging is not fast, it is not too slow, and consumers should pay attention to the power and actual charging efficiency of the charger when purchasing.
3, the difference is that the wireless charger will have a loss when charging, and the loss is 30-4 percentBetween 0. So the ordinary charger is faster than the wireless charger. There are already fast chargers and fast wireless chargers, but the results are the same. For example, the fast charging Samsung S8 takes 90 minutes, then the fast wireless charger takes 190 minutes, which is the result of my own actual testing.
1, hello, please place the phone screen facing up in the center of the charger or the position suggested by the charger manufacturer to charge.
2, the wireless charger power directly to the phonePlace the screen facing up in the center of the charger or as recommended by the manufacturer to charge.
3, open the mobile desktop, enter the 【 Service 】 menu. Click My at the bottom right and select My Device. Click and select [View device parameters] to continue the next step. Select the "Fast charge" option to check whether the current phone supports wireless charging. After confirming, put the phone in the [wireless charger] and display the [charging tips].
