OPPO supports wireless charging of mobile phones: OppoFindXoppoFindX3pro, oppoFindX3neo, oppoFindXopporenoopporeno8pro, oppoFindX5pro, oppoaceoppofindn, oppox2021. The opporeno8 is a smartphone released by OPPO.
OPPOFindX3Pro: OPPOFindX3Pro is OPPO's top flagship phone, supporting two-way wireless charging technology, can support up to 10W wireless charging output and up to 10W reverse charging input. OPPOReno5Pro 5G: OPPOReno5Pro 5G is a 5G mobile phone with a very cost-effective, supporting a maximum of 30W VooC flash charge and a maximum of 10W reverse charge, in terms of wireless charging, supporting a maximum of 10W output power.
oppo mobile phone currently only oppoAce2 supportWireless charging, support 40w wireless flash charge, 65w wired fast charge. Released in April 2020, the phone features a 5-inch flexible panel with a straight screen and a back case available in "silver, gray, and purple."
OPPO vice President Shen Yiren recently exposed a high-profile new tail - OPPO Ace 2 5G, which has many highlights. According to the blogger @digital chat station, this phone will be equipped with 65W super flash charge, and more surprising is that it will also support wireless VOOC flash charge technology, which is rare in the current market.

OPPOAce2 stands out for its superior performance and comprehensive flash charging experience. This phone is equipped with Snapdragon 865 processor, support 65W wired flash charge, 40W wireless flash charge and 10W reverse wireless flash charge, whether it is daily use or emergency charging, can be fullThe principle of response. Wireless charger refers to the charger that does not need to be connected to the terminal device that needs to be charged without the traditional charging power cord, using the latest wireless charging technology, through the use of the magnetic field generated between the coils, the magic transmission of electrical energy, inductive coupling technology will become a bridge connecting the charging base station and equipment.
Using the principle of electromagnetic induction charging equipment, its principle is similar to the transformer, through the transmitter and receiver end set coil, transmitter coil under the action of power to send electromagnetic signals, the receiving end coil receives electromagnetic signals and convert electromagnetic signals into current, so as to achieve the purpose of wireless charging.
Wireless charging principle has electromagnetic induction, magnetic field resonance and radio wave and so on. Electromagnetic induction type primary coil a certain frequency of alternating current, through electromagnetic induction in the secondary coil to produce a certain current, thereby transferring energy from the transmission end to the receiving end.
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. 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 phoneClose to the magnetic field, an electric current is generated to charge the phone.
Fixed frequency is better. The working principle of the frequency conversion architecture is to adjust the transmission power by changing the operating frequency, which will cause certain interference to the mobile phone circuit in some transmission bands, and the fixed frequency does not appear this problem.
In the Qi standard, there is a fixed frequency voltage regulation mode of work. That is, the fixed operating frequency, according to the dynamic load power requirements, through the voltage regulator unit, to achieve dynamic power output.However, the existing voltage regulator on the market first fixed the operating frequency of the voltage regulator itself, and then adjusted the input duty ratio to achieve the adjustment of the output voltage. The inherent disadvantages of this method are: 1) When the input voltage changes, it will directly affect the output stage.
iWALK Magic Scorpion charger is really ideal for wireless charging, taking Apple mobile phones as an example, support 5W fixed frequency fast charging. In the actual test, the fast charge head of 5V/2A is used, and the average is about 6W. It takes 2 hours and 50 minutes to charge to 100%, and during the charging process, there is no special hot casePresent.
