Mi 11Pro support space charging space charging and wireless charging is a certain difference between wireless charging need to be close to the wireless charger can be charged, and space charging is not limited to the conditions of use, as long as the user enters a specific area can be charged space charging advantages 1, the phone does not need to plug in, do not use the base.
Apple has tried WiFi charging, Samsung has also had the idea of charging rings, and the successive announcements of Xiaomi and MOTOROLA indicate that air charging technology may become 2021A new bright spot in the electronics industry. This will not only change the way mobile phones are charged, but will also push the entire industry towards a more intelligent and efficient direction.
Mobile phone charging space technology appeared millet launched wifi wireless charging upgrade This new technology, through wifi wireless charging upgrade their unique charger and mobile phone can achieve space charging, The distance between this space can be one meter, or two meters, which is useful within a certain range, but the charging speed is not so high ifIf it is this kind of space charging, it is now 5 watts of charging power.
Some are true and some are false. If the seller causes the wifi wireless charging upgrade that damages the rights and interests of consumers, consumers can negotiate with the seller to deal with wifi wireless charging upgrade , if the negotiation fails, you can report to the consumer association for mediation and adjustmentIf they fail to do so, they may file a lawsuit with the relevant people's court for safeguarding their rights.

After investigation and research, we can conclude that there are real and fake Wi-Fi products sold on Tiktok, and we cannot guarantee that all products are real and effective. Portable WiFi is a portable wireless Internet access device that provides an Internet connection and can share the network between various devices. On Tiktok, there are many manufacturers selling such devices.Portable wifiThere is nothing wrong with it. But people in the industry should know that the people who sell portable WiFi on a certain sound are running businesses. The first month will allow you to use well, the second month begins to limit only the pack year, and then run straight away.
The portable WiFi sold on Tiktok is more of a virtual network service, and users actually access the Internet through a proxy when they connect, rather than providing a real WiFi signal. These virtual WiFi services pose a security risk, as all data may pass through third-party servers and personal information and privacy may be compromised.
It is true that you need to buy a wireless WiFi charger or it can be charged in the corresponding wireless charging station, and the ordinary wireless of the family can not be charged. The principle of wireless charging of mobile phones is as follows: In a wireless power supply device, electrical energy generates radio waves through a wave source to excite the transmitting coil. When the receiving coil is close to the transmitting coil, the two coils act like a circuit, distributing electromagnetic energy evenly.
Is true, the following is the report. Recently, comeResearchers from the University of Washington have invented a new technology that can charge smartphones with different systems, including iphones and Android, via a router's Wi-Fi signal. Charging through the router's Wi-Fi signal has a maximum effective distance of 28 feet (about 53 meters), and you can still access the Internet during the charging process.
Ambient back reflection technology allows devices and sensor networks to transmit data by reflecting existing signals for information exchange, without the use of batteries. Study co-author, University of Washington Computer Science, Engineering and ScienceJoshua Smith, associate professor of electrical engineering, said: "Our device can form a network 'out of nothing'. You can reflect those signals and communicate in Morse code between battery-free devices.
In general, wireless charging can not be as far away as WiFi, only close to the charging surface because of magnetic resonance. This method is actually more reliable to use, and it is also relatively easy to use on the phone. Only close to the mobile phone can really be full of mobile phone power, wireless charging technology has been constantly developing. We'll have all the electrical equipmentWe'll take care of everything. It won't bother him.
Convenient: no need to connect with a wire when charging, as long as it is placed near the charger, there is no need to occupy multiple power sockets, there is no trouble of multiple wires winding each other. The disadvantages of wireless charging are slightly lower in efficiency: the general charger also has a transformer, but the wireless charging transformer composed of the transmitting coil and the receiving coil is limited in structure, and the energy transmission efficiency is theoretically slightly lower than that of the general charger.
Does wireless charging mean no cable? No, it just uses the principle of Qi electromagnetic induction to contact the charging board when chargingLine charging.
