1, need to support the receiving device that meets the QI wireless charging protocol, whether to support the QI protocol, it is recommended to consult the equipment manufacturer, such as: electric toothbrush, razor, mouse,Headphones, toys, accessories, etc.; The receiving device is placed in a central position on the back of the phone. Do not place metal materials such as bus passes and coins between the receiving device and the mobile phone. After the wireless reverse charging function of the phone is turned on, do not place the phone directly on the metal material. 2, Recently, there is news that Huawei will cancel the reverse charging function of its flagship phone P40 series. The news has aroused wide attention and discussion. But in fact, Huawei can not easily eliminate the reverse charging function. Here's a detailed explanation: The basic principle of reverse charging Reverse charging means that the phone can share its own power with other devicesSuch as headphones, bracelets, other mobile phones and so on.
3, it is recommended not to use reverse charging, which will shorten the battery life, or buy a charging bank.
4, there are many main long-life mobile phones on the market, mainly with large battery capacity to improve standby performance. As the battery capacity gets larger and larger, many manufacturers begin to think about whether they can provide users with more functions, and reverse charging is born in this way. The first time we learned about reverse charging was from Huawei Mate7, when the operation effect was demonstrated at the press conference, just connect a data cable, which is actually a common OTGThe data cable.
The difference between the Mi 10 and the Mi 10 Pro is as follows: Different battery capacity. The Mi 10 uses a 4780mAh battery; The Mi 10Pro uses a 4500mAh battery. The Mi 10 has a battery capacity 280mAh larger than the 10Pro. Charging cable is different. The Mi 10 uses 30w wireless and 10w reverse charging. The Mi 10Pro uses 50w wired, 30w wireless and 10w reverse charging. Chargers are different.
The system version is MIUI1, and the differences between Mi 10pro and Mi 10 are as follows: Although the two models use 100 million pixel cameras as the main camera, the lens specifications are different. The Mi 10 has a 7P lens, while the Mi 10Pro has been upgraded to an 8P lens, and its three secondary camera configurations are also higher. In addition, the Mi 10Pro supports 10x hybrid optical zoom and 50x digital zoom, with a laser focus sensor.
The main differences between the Mi 10 and the Mi 10 Pro are as follows: Hardware configuration: Mi 10The received energy is used to charge the battery and at the same time for its own operation.
Mobile phone wireless charging refers to the meaning that the charger and the electrical device can be connected to the phone without wires.
Wireless charging, also known as inductive charging, non-contact inductive charging, is the use of near-field induction, that is, inductive coupling, by the power supply device (charger) to transmit energy to the device that uses electricity. If the distance between the charger and the electrical device is far, it is necessary to use resonant inductive coupling design.
Mobile phone wireless charging technology is completely without the use of wires, using magnets for the handMachine charging technology. Mobile phone wireless charging technology, derived from wireless power transmission technology, uses magnetic resonance to transfer charge in the air between the charger and the mobile phone, coil and capacitor form resonance between the charger and the mobile phone, to achieve efficient transmission of electric energy technology.
Wireless charging, also known as inductive charging or non-contact inductive charging, based on the principle of electromagnetic induction, it is not necessary to transmit electricity to the device like the traditional wired charger, but the device that needs to be charged can be charged by contacting the wireless charging base.
2, two-way fast charge means that both output and input support fast charging; The output supports fast charging, that is, when the charging treasure charges the mobile phone, the charging treasure and the mobile phone support fastFast charging, input support for fast charging, that is, when charging the charger and charging treasure support fast charging. At present, the charging speed is generally 5V, 2A is the base benchmark, the charging power exceeds 5V, 2A is the concept of fast charging, in principle, it is also divided into two directions of pulling high voltage and increasing current.
3, fast charge protocol: PD QC fast charge power: 10W wireless 18W wired This South Carolina wireless charging treasure battery capacity is 10000 MA, support QC18W and PD18W wired fast charge function, also support 10W wireless fast charge function. South Carolina Wireless power Bank POW2Triple heat dissipation design, whether wireless or wired charging will not be hot.
4, wireless fast charging is a combination of wireless charging technology and fast charging technology, and 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.
5, November 25 news, this afternoon Huawei officially sentWhen introducing the new MatePad Pro tablet computer, Yu Chengdong mentioned that this tablet is the first two-way wireless charging tablet. Huawei MatePad Pro is the world's first two-way wireless charging tablet, equipped with 7250mAh large-capacity battery, support 40W super fast charge 15W forward wireless fast charge, 5W reverse wireless fast charge technology.
