Wireless charging system mainly adopts the principle of electromagnetic induction. 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, by using the magnetic field generated between the coils, the magic transmission of electrical energy, inductanceThe device can wirelessly charge devices with single wireless charge and dual wireless charge. Most of them are used for wireless charging of mobile phones. Wireless charging is not only the charging device to charge the phone wirelessly; Also includes reverse wireless charging, after the mobile phone is set up the wireless reverse charging function, the mobile phone becomes single wireless charging and double wireless charging a wireless charger, which can charge other mobile phones that support wireless charging technology.
2, two-way wireless charging means that both devices support reverse charging technology, and also have the ability to wireless chargingForce, so that the two devices can charge each other single wireless charge and dual wireless charge . Reverse charging refers to the mobile phone and other devices that can only receive wireless charging electromagnetic waves, and now can emit electromagnetic waves through the wireless coil to charge other devices that support wireless charging. However, its charging power is small and can only serve as an emergency use.
3, Huawei two-way wireless charging means that both devices support reverse charging technology, and also have the ability to wireless charging, so that the two devices can charge each other. HUAWEI Technologies Co., LTDTECHNOLOGIES CO., LTD., founded in 1987 and headquartered in Longgang District, Shenzhen City, Guangdong Province, China, is a private communication technology company that produces and sells communication equipment.
4, Huawei two-way wireless charging means that the two devices support reverse charging technology, and the two devices have the ability to wireless charging, so that the two devices can charge each other. Huawei Technologies Co., Ltd. is a private communications technology company that produces and sells communications equipment. Huawei Technologies Co., Ltd. was founded in 1987 and is headquartered in Longgang District, Shenzhen City, Guangdong Province, China.
5, Apple two-way wireless charging technology refers to the method of charging between two devices. The result of this technology is to have two devices with wireless charging capabilities at the same time. The principle of Apple's two-way wireless charging technology is to use magnetic resonance technology, by transferring electricity between two devices in close proximity. Specifically, the technology is based on the Qi standard and uses a frequency of 5W.
6, this tablet is the first two-way wireless charging tablet. Huawei MatePad Pro is the world's first two-way wireless charging tablet, equipped with 7250mAh large-capacity battery, support 40W super fastCharge 15W forward wireless fast charge, 5W reverse wireless fast charge technology. The mainstream products on the market that support the QI wireless charging protocol can all achieve mutual wireless charging with Huawei MatePad Pro, providing users with a faster and more convenient battery life experience.
1, through the power supply module after the output of direct current through 2M active crystal inverter into high frequency communication power supply of low winding. tongAfter the two inductors couple the energy, the electrical output of the secondary coil is changed into direct current to charge the battery.
2, wireless charging base to increase the coil, or do not modify it, you increase the coil not only did not play a good effect but affect the speed of charging, increase the coil is equal to increase the resistance, it will make the current slow, the coil is proportionally wound, too much or too little can not, coil wound less, there will be damage to the parts, resulting in parts burned spark, For some do not arbitrarily modify the wireless charging base.
3, Zikko Apple wireless charger compared to the market commonIt has the advantages of high 10W fast charging, multi-coil no need to align to a fixed position, and all-round charging. Equipped with high 10W dual coil wireless transmission power, compared to the common single coil, it does not need to be aligned to a fixed position when charging. It has three modes of horizontal and vertical placement, no matter it is horizontal, horizontal and vertical placement, it can truly achieve all-round charging.
4, in practical applications, I recommend millet wireless charger (20W wireless charging power, double coil design mobile phone can be placed vertically or horizontally) as the first choice, because of its excellent performance in appearance design, charging performance and quality.
5, the vertical wireless charger adopts the classic base and support board design, simple and dignified. Product parameters show that it supports dual coil output, moderate size, using PC ABS material. The internal configuration of FCC, CE, ROHS, Prop65 and other certifications to ensure safety and reliability. The smart design of the support board can stabilize the mobile phone, which is convenient to watch TV series or receive information, and improve the user experience.
6, can. The iPhone11 supports Qi wireless charging, and its charging power is 5W. Qi wireless charging refers to the use of Qi wireless charging standard protocol for wireless charging of mobile phonesThe way. This charging method is based on electromagnetic induction mode for mobile phones, digital cameras, handheld playback devices or other low-power devices.
1, LANWK charge quickly, a very small wireless charger, national tide is full, things are good, thinner than imagined, charging response is fast, worth starting! Looks pretty, small and delicate, charging speed is very fast. Nergin (NILLKIN's ambient light is also great and can be used as a night light at night! The charging speed feels acceptable, 40% of the charge is basically full in two and a half hours.
2, Leiber XC500 wireless charger Leiber XC500 wireless charger packaging is still familiar Leiber family style, the classic blue main vision is clear. Although the body is thin, due to the alloy base, coupled with four non-slip foot pads at the bottom, it is also stable on the desktop.
3, green link PD 45W dual-port charger is a very practical charger, the use experience is very notWrong. The following is the specific evaluation of the charger: Efficient charging: Green Link's PD 45W dual-port charger supports fast charging, using a USB-C interface, which can provide 45W power output. This means it can quickly charge the device, saving the user time waiting.
4, advantages, easy to use, have their own office or study, the kind of place with the feeling of a great. Moreover, because wpc and pma two charging protocols are supported, so do not buy the official wireless charger can also be used, Taobao to buy dozens of pieces can be used, the choice is very many. Cons, charging a littleSlow, because wireless charging conversion will have losses. It's a little hot. I can't play happily with my phone while charging.
