3, in order to better experience the magic of magnetic charging, the floor owner started the wheat Duo magnetic charger at the same time, but also started his home matching magnetic phone case, the outer packaging of the two uses the same white orange matching color. Among them, the front of the magnetic charger is printed with a picture of the product, and marked with magnetic charging, 15W wireless charging, magnetic charging, built-in bracket structure and other characteristics.
4, magnetic charging is through the magnet male and female suction, so that the charging cable and the jack can be connected to charge. Essentially, it's still wired charging, just by plugging inEquation becomes adsorption equation. This is very different from wireless charging, magnetic charging can not be charged without a line. Wireless charging is a technology that does exist, and the technology has been widely used in electronic devices.
5, Millet 10 new flagship Mi 10, has up to 30W wireless flash charge function, minutes to increase the power, and there is 10W fast wireless backcharge, that is, you can charge millet 10 for other mobile phones that need to be charged.
6, RAVPower: RAVPower is a domestic brand, but also a well-known cross-border electricityBrand, mobile power is its main product. So far, the products have been exported to some European and American countries. Mophie: Mophie is an American brand, which focuses on the manufacturing of mobile intelligent devices, and is also the first certified wireless charging brand of Apple Inc. Its product line is also relatively rich, with wireless and wired two categories.
1, fixed frequency is better. The frequency conversion architecture works by changing the operating frequency to adjust the transmit power, which in some transmit frequency bands will affect the mobile phoneThe circuit causes some interference, and the fixed frequency does not appear this problem.
2, in the Qi standard, there is a fixed frequency voltage regulation mode of work. That is, the fixed operating frequency, according to the dynamic load power requirements, through the voltage regulator unit, to achieve dynamic power output. However, the existing voltage regulator on the market first fixed the operating frequency of the voltage regulator itself, and then adjusted the input duty ratio to achieve the adjustment of the output voltage. The inherent disadvantages of this method are: 1) When the input voltage changes, it will directly affect the output stage.
3, iWALK magic Scorpion charger is really not on wireless chargingOften ideal, taking Apple mobile phones as an example, support 5W fixed frequency fast charge. In the actual test, the fast charge head of 5V/2A is used, and the average is about 6W. It takes 2 hours and 50 minutes to charge to 100% power, and during the charging process, there is no special hot fuselage.
4, Hello! Since the release of the iPhone8 series, the green link has launched a number of wireless chargers matching the Apple iPhone8/8P/X wireless charging function, of which the green link CD181 is specifically for the 5W wireless fast charging function of Apple ios12, adding the 5W fixed frequency chip design, so thatDemand, through the voltage regulator unit, to achieve dynamic power output. However, the existing voltage regulator on the market first fixed the operating frequency of the voltage regulator itself, and then adjusted the input duty ratio to achieve the adjustment of the output voltage. The inherent disadvantages of this method are: 1) When the input voltage changes, it will directly affect the output stage.
Fixed frequency is better. The working principle of the frequency conversion architecture is to adjust the transmission power by changing the operating frequency, which will cause certain interference to the mobile phone circuit in some transmission bands, and the fixed frequency does not appear this problem.
Socket contact is poor. Change charging position, rowIn addition to the socket caused by poor contact intermittently lead to replacement of the standby charger if conditions allow for testing. Or send it to the repair test to check whether there is a foreign body in the mobile phone charging interface, such as liquid intake and debris, resulting in poor contact between the mobile phone charging interface and the charger.
Yes. According to the query, the inverter to charge the mobile phone is a very useful technology, can convert the power into the voltage required by the mobile phone, so that the mobile phone charging faster and safer, can also suppress electromagnetic interference, reduce noise, improve the stability of the power supply, so as to ensure the charging safety of the mobile phone.
pcs refers to the energy storage converter, which controls the charging and discharging process of the battery, carries out AC/DC transformation, and can directly supply AC load in the case of no grid. PCS is composed of DC/AC bidirectional converter, control unit, etc. The inverter is a converter that converts direct current energy (battery, battery) into constant frequency voltage or frequency modulation voltage regulation AC (generally 220V, 50Hz sine wave). It consists of inverter bridge, control logic and filter circuit. Of course, according to the charging head network, the Apple is likely to regulate the industry standard for wireless fast charging, and this is not all third-party 5WWireless fast charge is blocked, as long as it is officially recognized by Apple, such as mophie, Belkin, Logitech, Native Union, Anker and other brands are not affected.
