The wireless charging power bank has been around for a while, and its simplicity and ease of use has allowed users to taste the sweetness of the new technology. It is a trend to replace traditional mobile phone chargers with wireless charging power banks. Wireless chargers have been around for a while, let’s talk about the advantages of wireless charging power banks?
With years of experience in the development and production of wireless charging power banks, wireless charging power bank manufacturers believe that wireless chargers have reasons and advantages to replace traditional chargers:
1. The wireless charging power bank is convenient: there is no need to connect with wires when charging, as long as we put it near the charger. In the case where multiple users’ electrical safety devices are required, enterprises can directly save multiple chargers, do not occupy multiple system power sockets, and do not have the trouble of forming multiple wires entangled with each other.
2. Wireless charging power bank safety: no power connection design to avoid the danger of electric shock.
3. The wireless charging mobile power supply is durable: because the power transmission components are not exposed, they will not be corroded by moisture and oxygen in the air, and there will be no mechanical wear and loss caused by flashover during the connection and separation process.
4. A final advantage of wireless charging power banks is that by replacing traditional wireless phone chargers, they reduce the number of data cable loopholes and eliminate the need for users to be tangled with data cables.
The difference between wired charging and wireless charging is: the input of wired charging is a constant voltage source, which uses a DC-DC (DCDC) converter, usually a switched capacitor (SC), to achieve segmented power supply to the mobile phone battery (constant current, constant voltage, variable current charging). In the wireless charging mode, the energy generates a high-frequency induced voltage in the mobile phone receiving coil through the high-frequency magnetic field, and the frequency is generally above 100kHz. The mobile phone battery is realized by compensation topology (necessary for inductive wireless charging system), synchronous rectifier, and DCDC converter. segmented power supply. Someone watched it and updated the comment section. Some students mentioned the effect on temperature. This is indeed a difference between inductive power transfer systems and wired systems, mainly in system efficiency.
