Different modes of operation: Direct charging directly through the interface function of the platform, obtain the authorization code of the recharge card, and then automatically complete the recharge and feedback the result to the user; Recharging is carried out through the third platform, and the process is relatively complicated, requiring users to provide their own recharging card number and password.
Recharge method is different, the amount of the account is different. Recharge methods are different: Flash Krypton direct charge is directly in the game or the official website for recharge, and substitute charge is through a third-party platform for recharge. The amount to the account is different: flash krypton direct charge is how much to recharge, how much to the account, and there will be a discount.
Replacement charging is more expensive than direct charging reasons: replacement charging to charge a part of the money as their own handling fees, direct charging is directly from the platform recharge, no additional costs. There are more items that can be recharged, and relatively few items that can be directly charged. Many are overseas accounts, to charge a part of the overseas fees. Direct flushing is not necessary> What is the principle of wireless charging of mobile phones?
Wireless charging methods include electromagnetic induction, magnetic resonance, electric field coupling and radio wave transmission, etc. Wireless charging of mobile phones mostly uses the principle of electromagnetic induction. Electromagnetic induction wireless charging, when the current of the power supply through the coil (wireless charger's power supply coil) will generate a magnetic field, other unenergized coil (mobile phone side of the electric coil) close to the magnetic field will generate current, charging the mobile phone. As shown below.
Wireless charging, also known as inductive charging or non-contact inductive charging, based on the principle of electromagnetic induction, does not need to be like traditional wired chargingThe device also needs a transmission cable to transmit electricity to the device, but the device that needs to be charged can be charged by contacting the wireless charging base.Basic principle: The use of electromagnetic induction, that is, the primary coil of a certain frequency of alternating current, through electromagnetic induction in the secondary coil to produce a certain current, so as to transfer energy from the transmission end to the receiving end.
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 endSupply power to the system. 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.
The principle of mobile phone wireless charging is as follows: the electromagnetic induction charging base and the mobile phone terminal are respectively built with coils. When the two are close, the transmitting coil generates a certain current in the mobile phone receiving coil based on a certain frequency of alternating current through electromagnetic induction, thereby transferring the electrical energy from the transmitting end to the receiving end, and then the charging seat supplies power to the mobile phone.

Wireless charging, also known as inductive charging or non-contact inductive charging, based on the principle of electromagnetic induction, it is not necessary to transmit electricity to the device like the traditional wired charger, but the device that needs to be charged can be charged by contacting the wireless charging base.
Wireless charging methods include electromagnetic induction, magnetic resonance, electric field coupling and radio wave transmission, etc. Wireless charging of mobile phones mostly uses the principle of electromagnetic induction. Electromagnetic induction wireless charging, whenWhen the current of the power supply passes through the coil (the power supply coil of the wireless charger), a magnetic field is generated. When the other unenergized coil (the power supply coil of the mobile phone) is close to the magnetic field, a current is generated to charge the mobile phone. As shown below.
The principle of wireless charging technology is "magnetic electricity", simply put, through the charging device and the mobile phone device installed on the two "magnetic equipment" mutual induction and formation of current. At present, products supporting wireless charging have appeared in mobile phones, electric vehicles, smart furniture and other fields. Among them, in the mobile phone industry, the "Qi standard" is the most common, which is often introduced in the packaging of many mobile phones and wireless chargersIt's going to be labeled Qi.
