1, in terms of charging speed, Apple 8p original wireless charger also performs well. It adopts...With the Qi wireless charging standard, the maximum output power can reach 5W, which can meet the daily charging needs of ordinary users. At the same time, the charger also supports the fast charging function, which can fully charge the phone in a short time.
2, w charge slowly. 10W charging refers to the charger output power of 10W, that is, 5V2A voltage and current output. 10 watts of wireless charging is still relatively slow, an hour is estimated to be able to charge about 60% of the electricity, basically in about an hour and a half can be full of mobile phone batteries. In the case of the iPhone, the official charging time is five hours on a full charge. Such asThe principle of response. 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, through the use of the magnetic field generated between the coils, the magic transmission of electrical energy, inductive coupling technology will become a bridge connecting the charging base station and equipment.
Mobile phone wireless charging refers to the meaning that the charger and the electrical device can be connected to the phone without wires.
Wireless charging, also known as inductive charging or non-contact inductive charging, based on the principle of electromagnetic induction, does not need to transmit electricity like the traditional wired charger requires a transmission cableInstead, the device that needs to be charged can be charged by touching the wireless charging base.
The basic principle of wireless charging is to convert the current into a magnetic field, which is transmitted through the air and then converted into a current to be transmitted to the intelligent terminal. When the system works, the input end converts the AC mains into direct current through the full bridge rectifier circuit, or uses the 24V direct current end to supply power to the system directly. After passing through the power management module, the output direct current is converted into high-frequency alternating current through the 2M active crystal oscillator inverter to supply the primary winding.
Wireless charging, also known as inductive charging, non-contact inductive charging, is the use of near-field induction, alsoIt is inductive coupling, where the power supply device (charger) transfers energy to the device that uses electricity. If the distance between the charger and the electrical device is far, it is necessary to use resonant inductive coupling design.
Mi 14 wireless charging support 50W. This charging power can ensure that the phone gets a considerable amount of power in a short period of time, thus improving the user experience. Wireless charging technology has been widely used in the mobile phone industry in recent years, which provides users with more convenient and unnecessaryThe charging mode of the cable. Xiaomi, as a well-known mobile phone brand, has been continuously promoting the wireless charging technology of its products.
The charging aspect of Xiaomi 14 that we are most concerned about, the two versions of the phone will use 90w and 120w wired fast charge, and the same 50w wireless fast charge. Support wireless charging with 50w wireless fast charging speed The two models of this phone are wireless charging function, both are 50w speed. In terms of charging, one supports 90W wired fast charge, and the other 120w wired fast charge, both 50w wireless fast charge.
W Wireless reverse charging. Mi 14 built-inThe 4610mAh battery supports a variety of charging methods. Support 90W fast charge and 50W wireless charging, can be wired or wireless fast charging. The Mi 14 supports 10W wireless reverse charging and can be used as a wireless charger to provide charging functions for other devices that support wireless charging.
Generally, the transmission distance of high-power wireless charging can reach 5 meters at about 0.9-2 meters. Wireless charging technology can be divided into two kinds of low-power wireless charging and high-power wireless chargingStyle. Low-power wireless charging often uses electromagnetic induction, such as the Qi method of charging mobile phones, but ZTE's electric vehicle wireless charging method uses induction.
The core magnetic resonance medium and long distance wireless charging developed by Spurotin can successfully achieve wireless charging within one meter.
Currently known reports, the farthest distance is 10 meters, using electromagnetic wave technology. The existing wireless charging technology uses magnetic field, electromagnetic wave, laser, ultrasonic and other energy transfer media. The 10-meter technology mentioned above, which uses electromagnetic waves as a medium, remains in the laboratory stage. Orders,Before the commercial market is mainly the magnetic field for the medium technology, divided into magnetic induction and magnetic resonance 2 technologies.
