1, the charging speed is slightly slower: Compared with the wired charging bank fast charging mobile power wireless charging , even with the fast charging mobile power wireless charging , the charging speed of the wireless charging bank fast charging mobile power wireless charging will be slightly slower, especially forDevices with large capacity batteries take longer to charge. 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.
2, different conductive properties, different ways of use. Wireless charging treasure usually uses the principle of electromagnetic induction to charge, in which the coil is usually copper wire. Copper wire has good electrical conductivity and can effectively transmit electrical energy. The wired charging bank uses a traditional charging cable, and the conductor is often copper wire to ensure low resistance and high conductivity.
3Although both charge devices such as smartphones, there are still 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, which supports PD two-way fast charging, and the charging speed is faster than the general product. Wireless charging treasure does not need interface support, as long as it supports wireless charging function can be used.
4, wireless charging bank does not harm the mobile phone battery. Because the working frequency of wireless charging is now below 1M, it will not affect the signal of the mobile phone. phaseOn the contrary, wireless chargers not only reduce the use of data lines, but also make charging methods more free and safer. It is basically the same as wired charging, but the rate is lower, but the wireless charger still has a high energy conversion rate, which saves energy consumption more.
5, the working principle of wireless charging treasure is mainly based on electromagnetic induction technology. When the power bank and the device (such as a smartphone) are near each other, the power bank generates an alternating magnetic field, which is sensed by the receiving coil within the device and converted into an electric current, thus charging the device's battery. This process is different in nature from wired charging, but it's notCan cause additional damage to the battery.
6, each has its own advantages: wireless charging is convenient, do not need to connect the phone to the charger, put on the charging board; Wired charging is more stable, and the charging speed is faster than wireless charging.
Huawei's CP020 mobile power supply, the official price of 300 yuan, for a 12000 mah charging treasure, this price seems to make people suspicious. However, once you dig deeper, you will find that this is "far ahead".There is indeed a reason behind it. First of all, its ceramic-like material feels warm, the texture exceeds the ordinary charging bank on the market, the design is simple and atmospheric, and the logo is eye-catching, reflecting Huawei's consistent pursuit of high quality.
There are two models, the specific prices are as follows: For more information, please visit Huawei Mall.
HUAWEI officially held the HUAWEI P30 series press conference in Shanghai, and released the Huawei P30 series blockbuster products as well as the new generation of HUAWEI MateBook X Pro and Huawei MateBook 13. In addition, Huawei is also officialReleased 40W super fast charge mobile power supply, the mobile power supply has been put on the official mall, but the specific price has not been announced, Huawei officially announced the price today, 369 yuan.
The official price of 299 yuan feels like it is directly set to the ceiling, so expensive mobile power is sure no one is willing to buy, then let the next generation of consumers dismantle. Unpacking article: The delivery is used for the custom express transportation box for the mall, the side is written VMALL.com is the website of the Huawei mall, and it is also marked that the after-sales service can be returned in 7 days and 15 days for replacement, and the national protection.
At leisure fishUltra-thin design, showing impressive portability. The 5000mAh battery capacity not only meets the needs of daily use, but also is particularly compatible with various types of magnetic mobile phone protection cases, with the built-in strong magnetic array, to achieve a convenient experience of wireless charging.
2, Black shark MagSafe magnetic wireless mobile power came into being, it not only supports Apple's MagSafe protocol, but also equipped with PD20W fast charge, becoming a portable charging station for iPhone users, providing convenience for busy life. The Black Shark brand, with its success in the field of gaming mobile phones, conveys the strictness of product qualityControl.
3, Black shark charging treasure Black shark this charging treasure has 20000mAh large battery, two-way fast charge, support Apple PD20W fast charge, strong endurance, in line with aviation management standards, can be safely and assured to take the plane. Small and portable body, so that travel without weight.

Small and portable body, so that travel without weight.
Advantages Safety: no power contact design, can avoid the danger of electric shock. Durable: the power transmission element is not exposed, so it will not be eroded by water and oxygen in the air; There is no contact, so there will be no mechanical wear and fire loss during connection and separation.
In the past two years, wireless charging technology has gradually matured, and major brands have launched wireless charger products, the main advantage is its convenience and versatility, the mainstreamBrands including Samsung, Philips, Green Link, etc., the following will introduce you to three of the brands, in addition to know the brand, you also need to understand how to choose wireless chargers.
The first is the Apple Lighting data cable, a charging cable designed by Apple Inc. for Apple digital devices. The second is the Android Micro to USB interface data line, one side is a narrow plane, one side is a plane with 2pcs small points, this data line, the transmission rate is low, gradually eliminated, at present, this data line on the market is not so common, replaced by Type-C numberAccording to the line.
Convenience: non-contact, one-to-many charging compared with the general charger, reduces the trouble of plugging, but also avoids the interface is not applicable, poor contact and other phenomenon, the elderly can also be very convenient to use. Versatility: A charger can charge multiple loads, and a family can buy a charger to meet the needs of the whole family.
Advantages of wireless charging: The use of wireless magnetic induction charging equipment can be invisible, the equipment wear rate is low, the application range is wide, and the public charging area is relatively reduced. High technical content, easy to operate, can be implemented relatively long distanceConversion of line electrical energy. 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.
