Slightly slower charging speed: compared to wiredCharging treasure, even with fast charging, wireless charging treasure charging speed will be slightly slower, especially for large-capacity battery equipment, charging time is longer. Compatibility limitations: Wireless charging bank requires devices to support Qi or other wireless charging standards, and devices that do not support wireless charging technology cannot enjoy its convenience.
Apple cable charge well. The advantage of the magnetic magnet is that it can be adsorbated near, and the adsorption can be charged. The charger is automatically aligned with the position of the charging coil, which solves the problem of manual alignment for traditional wireless charging. But it is still a wired form, and the power is not as good as wired charging, so the keyTime or wired charging is more realistic. If the MagSafe magnetic charger wants to turn into a regular one, it will depend on when the iPhone removes the charging port.
The second kind of wireless charging, its working principle is the most used electromagnetic induction, wireless charging less line bondage, each charge on the go, compared with wired charging, it does not plug and unplug the data cable cumbersome, so charging is more safe, more fast, its disadvantage is that the charge is relatively slow.
The biggest difference is that the charging method is not the same. The traditional charging bank charges the mobile phone, basically through the wire transmission, charging speed is faster; There is noWhen charging a mobile phone with a cable charger, it does not require a cable to be unplugged, but it is slower. Wireless chargers do not need wire transmission, mobile phones need wireless charging function has become a trend, the wide use of wireless charging can make our mobile phone life more convenient.
What is the difference between wireless charging and wired charging bank? Although both are used to charge devices such as smartphones, there are some differences. Simply put, wireless charging is more convenient, does not require wire entanglement, can remove the trouble of wire; The wired charging treasure is faster in charging speed, such as the Secretary-General is a wired charging treasure,Support customer customization, encryption, fast charging are done, in 15-16 years Apple, Samsung are using wireless charging scheme compared their scheme. The Japanese plan has been weak and used by few people. Domestic programs have bee electronics, Printec, New Jet and so on.
aigo AIGO Digital Technology Co., Ltd. was founded in 1993, as a well-known domestic IT digital brand, enjoys a high reputation, with the strong strength of the enterprise and industrial appeal to launch the wireless charging program comparison phaseOff mobile power products. Its mobile power supply large capacity ultra-portable, stylish, lithium polymer battery ultra-safe, with high cost performance, worth buying. Mi IM Mi Mobile Power is a mobile charging device launched by Xiaomi.
On the new flagship Mi 10, there is a 30W wireless flash charge function, which increases the power of the minute, and there is a 10W fast wireless backcharge, which means that the Mi 10 can be charged for other mobile phones that need to be charged.
Rome is good. According to the query of relevant information shows that Roma Shi is a focus onMobile power supply, outdoor power supply, data charging cable, power adapter, car charging, plug-in and other 3C digital peripheral products of technology enterprises, Reisi wireless quality is not good as Roma Shi.
Rome's WSL10 wireless mobile power supply This is a 10000mAh wireless fast charging bank, in addition to thin and delicate, the performance is also very good wireless charging scheme comparison ! Romas wireless fast charging bank supports 10W wireless fast charging, compatible with Apple 5W wireless fast charging, which can charge mainstream wireless mobile phones. Users just need to easily place the phone on the charging bank, canCharge your phone.
Rome Shi wireless charging treasure WSL10 using frosted material, very feel. In terms of charging, support Android 10W wireless fast charging, Apple 5W wireless charging, without the trouble of charging with a charging line, with USB18W fast charging about an hour full, wired charging and wireless charging with different colors of the indicator light to distinguish, is a good design.
1, slow charging speed: due to the current mobile phoneMost of the receiving devices limit the input power, so the charging speed is slow. High cost: The charger needs to have an electronic circuit to push the coil, and the electrical device needs to have an electronic device to convert power, both also need to have a coil, and need a high-frequency filter circuit to meet FCC and other specifications, so the cost is higher than direct contact.
2, electromagnetic induction charging, very simple, and the principle of electromagnetic induction in high school is similar, wireless charging the charging base and the terminal are built with coils, so that the two are close to the charging seat and start to supply power from the charging seat to the terminal. This is the principle behind many wireless charging phones,However, the position must be relatively uniform to charge efficiently. And there is also coupling radiation problem, electromagnetic wave coupling will not exist a large magnetic field leakage. 3, there are four basic principles of wireless charging, respectively, electromagnetic induction charging, magnetic field resonance charging, radio wave charging, electric field coupling charging, the mainstream standards on the market mainly Qi standard, PMA standard, A4WP standard, iNPOFi technology and Wi-Po technology five. Let's take a look at the principle of wireless charging.
4, the use of wireless magnetic induction charging equipment can be doneInvisible, equipment wear rate is low, the application range is wide, the public charging area is relatively reduced. High technical content, easy to operate, can implement relatively long distance radio energy conversion. Disadvantages of wireless charging: Although the technical content of the equipment is high, the economic cost of the equipment is high and the maintenance cost is large.
5, - wireless power supply technology. This technology allows the charger to get rid of the limitation of the line and achieve complete separation of electrical appliances and power supplies. It shows better advantages than traditional chargers in terms of safety and flexibility. At present, there are four main technical ways to achieve wireless charging: magnetic induction technology, magnetic resonance technology, microWave technology and electric field coupling technology. Among them, magnetic induction technology and magnetic resonance technology are the technologies that are basically used in the current mass production products.
