1, mobile phone using wireless charging Doumen wireless charging coil , you need to buy wireless charging base or wireless charging back shell to use. Connect the charger to the wireless charging base Connect the charger to the wireless charging base Doumen wireless charging coil , and then place the mobile phone or the mobile phone with the wireless charging rear case on the wireless charging base.Take off the holster if the mobile phone holster is too thick or not the original charging holster wireless charging coil , may affect the charging effect, it is recommended to take off the holster after charging attempt.
2, this article will introduce three kinds of charging methods for the Doumen wireless charging coil , and the small details that need to be paid attention to when charging. Wired charging Connects your phone to a charger and adapter, then plugs it into an outlet. But be careful to choose a charge that matches the wireless charging coil your phone model and power supply standardAppliances and adapters.
3. First of all, you need to have a mobile phone that supports unlimited charging, such as iPhone X, iPhone8 plus, etc. Then you need to buy wireless chargers from formal channels, and it is recommended to buy them from official dealers. Then power on the wireless charger, make sure there are no magnetic objects around before connecting the power. Then place it in a flat place to prevent the phone from slipping off it.
4, connect the phone's standard charger and data cable to the wireless charger, and then put the phone directly (vertically) or horizontally around the wireless charger baseIn the middle position, wireless charging can be realized, the indicator light will have a breathing effect, and it will be extinguished after 5 seconds, plug and play, convenient and quick. two.
1, same size. The same size and as close as possible, otherwise it will have no effect, low conversion efficiency.
2, increase the output, you can select from the equipment, select a good electromagnetic coil. Because the transmitter and receiver of wireless charging are covered with wireless charging coils, the coils will have losses during operation and useGood material can reduce coil loss, can greatly improve the efficiency of wireless charging. Optimizing line and component selection To reduce losses, you can optimize line and component selection to deal with. Streamline and optimize the line, and select good materials for components to reduce output losses.
3, it is based on two core technologies: electromagnetic induction and vibration technology. Now, let's explore the secrets of these two technologies together! Electromagnetic induction technology is the first generation of mobile phone wireless charging representative, through the primary coil transmission of a certain frequency of alternating current, the use of electromagnetic induction in the secondary coil to generate current, to achieve energyWireless transmission.
4, the disadvantages of wireless charging efficiency is slightly lower: 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. Slow charging speed: Due to the current mobile phone and other receiving devices, most limit the input power, so the charging speed is slow.
5, Qi wireless charging system consists of a base station and mobile devices, the base station is the charging base we often see, the mobile device is the mobile phone through the electromagnetic induction principle charging base on the magnetic induction coil will powerWhat is the distance between wire charger transmitting coil and receiving coil? How much is the distance between the transmitting coil and the receiving coil of the wireless charger? QI Standard
1, the distance of the wireless charger can only be effective within the coil range of the charger, more than the distance can not receive charging, each manufacturer's product is different, can not be universal.
2, the technical principle, Qi charger and receiving equipment built-in conductive coil, the electromagnetic field generated after the base is energized will promote the coil in the receiving equipment into electricity, to achieve efficient and convenient wireless power supply. Although the Qi 2 standard supports up to 15W's fast charging, but the limitation of charging distance (usually a few millimeters to a few centimeters) is still a technical challenge. The two main highlights of Qi wireless charging are its convenience and versatility. 3, we often say that wireless charging actually has great limitations, the effective distance is generally only 8 mm -15 mm, in this range can be normal wireless charging, the so-called space is separated by a mobile phone shell empty only. If there is a metal interval, it will affect the normal charging.
