Can wireless charging and wired charging be done at the same time?

No, wireless charging and wired charging can not be carried out at the same time, can only choose one way to charge. Reason: For the safety of mobile phone charging, when connected to wired charging, automatic switch to wired charging, wireless charging stop. Wireless charging can only be charged if there is no connection line. Expand your knowledge: Wireless charging principles. 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. At present, the most common charging solution uses electromagnetic induction, in fact, electromagnetic induction solutions in the technical realization is not too mysterious, China's local BYD company, as early as December 2005 to apply for a non-contact induction charger patent, the use of electromagnetic induction technology. Magnetic resonance consists of an energy sending device and an energy receiving device, and when the two devices are tuned to the same frequency, or resonant at a specific frequency, they can exchange energy with each other, and that's a technique that's currently being studied. The research team, led by MIT physics professor Marin Soljacic, used the technology to light a 60-watt bulb two meters away and named it WiTricity. The diameter of the coil used in the experiment reached 50cm, which is not yet commercialized, and if the size of the coil is reduced, the receiving power will naturally decrease. Radio wave type This is a more mature technology, similar to the early use of ore radios, mainly composed of microwave transmitters and microwave receivers, can capture the radio wave energy bounced from the wall, adjust with the load while maintaining a stable DC voltage. This method requires only a transmitter mounted in a wall plug and a \"mosquito\" receiver that can be installed in any low-voltage product.
