1, the system version is ColorOS2, oppoace2 can be wireless charging, but it needs to be paired with oppo's own wireless chargingThe phone supports up to 40w wireless charging and 10w wireless reverse charging.
2, oppoace2 can be wireless charging, but it needs to be combined with oppo's own wireless charging base, supporting 40w wireless charging, AirVOOC wireless flash charging, the official stressed that this may be the world's first commercial high-speed wireless charging scheme. Support 10w wireless reverse charging. The Ace2 has a 4000mAh battery capacity and can be fully charged in as little as 56 minutes.
3, OPPO Ace2 supports wireless charging with a maximum power of 40W, fully charged onlyIt takes 56 minutes. Tip: For wireless charging, you need to purchase AirVOOC wireless flash charger base separately. Purchase details please see OPPO official website Oh ~AirVOOC charging board needs to connect 65W charging head and charging cable, in order to achieve the maximum 40W fast charge of OPPO Ace2. In hot weather, AirVOOC charging speed may be delayed.
1. Electromagnetic sensationThe alternating current of a certain frequency in the primary coil generates a certain current in the secondary coil through electromagnetic induction, thereby transferring energy from the transmission end to the receiving end.
2, wireless charging methods are electromagnetic induction, magnetic resonance, electric field coupling and radio wave transmission, wireless charging of mobile phones mostly uses the principle of electromagnetic induction. Electromagnetic induction wireless charging, when the current of the power supply through the coil (wireless charger's power supply coil) will generate a magnetic field, other unenergized coil (mobile phone side of the electric coil) close to the magnetic field will generate current, charging the mobile phone. As shown below.
3, the principle of wireless charging technology is actually very simple, "the so-called wireless charging technology, its basic principle is the same as the principle of transformers, is the principle of" electricity generated magnetism, magnetic generated electricity "that we have learned in middle school physics class.
4, mobile phone wireless charging is a relatively novel charging method, the principle is actually very simple, is to separate the ordinary transformer primary and secondary levels to achieve the purpose of wireless. Of course, the working level of wireless charging is relatively high, and even the role of energy transfer can be achieved between the iron core and the direct coil can be abandoned. Drawings to there are a lot, but will not send pictures, to tell you about the simplest wireless charging.
5, principle: the DC-DC switching power supply is divided into two parts at the high-frequency transformer, using resonant coupling; Then use RFID technology for data communication and current feedback. In a single-phase bridge rectifier circuit, if there is a filter capacitor, when the load is open, the output voltage (that is, the voltage at both ends of the capacitor) is the peak of the AC input voltage, that is, U output =414*U input, that is, the input voltage of the root 2 times.
6, the principle of electric field coupling wireless charging is to transmit electrical energy through the induced electric field generated by the coupling of two sets of asymmetric dipoles in the vertical direction. Suitable for short distance charging, high conversion efficiencyThe position can not be fixed; However, the disadvantage is that the equipment is large and the power is small. Therefore, at present, among the four wireless charging methods, electromagnetic induction wireless charging scheme is the most mature and most widely used in business.
Millet 55W vertical air-cooled wireless charging using PC flame retardant material plastic shell, fuselage edge clear end Angle arc transition, support board is black, base sandblasting treatment is goldColor. From the front, the front end of the base is equipped with LED indicators, and the support board is layered above and below, using different designs. Indicator light is green when working.
Millet vertical air cooled wireless charger price is 199 yuan, millet car wireless fast charge price is 139 yuan. Recently, Xiaomi's 5G era charging technology media communication conference held in Beijing can be said to be brilliant, high-profile display of the world's first 30W super wireless flash charging technology, and in the follow-up millet 9PRO conference also released related accessories products, 199 yuan vertical air-cooled wireless charging base, or very worth starting oh.
Charger OEM: The main enterprises include Aohai Technology, BYD Electronics, Tianbao, Selkang and so on. In 2020, fast charging technology enters the era of hundreds of watts. In August 2020, OPPO and Millet new machines are equipped with 120W fast charging, and fast charging technology has officially entered the 100-watt era. According to Xiaomi Lab data, the 100W fast charge takes only 17 minutes to fill the 4000 mAh battery. The increase of fast charge power drives the rapid increase of mobile phone charger prices.
Aohai Technology: wireless charging leader, is a focus on intelligent terminal charging and storage products researchDevelopment, production and sales of national high-tech enterprises.

Charging head network has introduced, Aohai technology is Huawei, millet, OPPO, vivo and many other mobile phone original attached charger core manufacturers, has a strong technical development capabilities and excellent quality control, at the same time, Aohai technology is also an excellent listed technology company, MOVE SPEED is the wholly-owned brand of Aohai Technology for consumers.
Mobile phones use wireless charging, you need to buy wireless charging base and wireless charging back shell to use. Usage: Connect the charger to the wireless charging base, then install the wireless battery back shell on the phone, and finally place the phone on the wireless charging base normally.
In theory, the wireless charger can be plugged when it is not used, the wireless charger is designed to be convenient to use, but if the user is notWhen using a wireless charger to charge, it is best to choose to turn off the power. For mobile phones that support wireless charging, just place the phone in the middle of the wireless charger to charge the operation, which is relatively convenient.
Mobile phones use wireless charging, you need to buy a wireless charging base or wireless charging back case to use. Specific usage: Connect the charger to the wireless charging base, and then place the mobile phone or a mobile phone with a wireless charging rear case on the wireless charging base. Note: If the phone case is too thick or not the original charging case, it may affect the charging effect, it is recommended to remove the skinTry charging after the set.
