Nowadays, many people have the habit of charging their phones in bed, and there are many safety hazards with portable sockets and various data cables. But wireless charging allows you to directly put down your phone for charging. Sometimes I can't open my eyes while playing with my phone, and plugging in a data cable is also a burden, which makes me lazy to charge. But if there is a wireless charging pad, you can simply extend your arm and place your phone on the charging pad.
Of course, there are also many people who are concerned about the harm of electronic devices to the human body, but in fact, there is no need to worry. A closed magnetic field is very safe and will not interfere with mobile phone signals. It also has the function of low-temperature fast charging, which will not heat up during charging. However, the most important thing is the charging effect. Although wireless charging is relatively slow, the effect is very stable.
Electromagnetic induction wireless charging generates a magnetic field when the current from the power supply passes through the coil, while other coils without electricity generate current to charge the phone.
Advantages of wireless charging solution:
1. Security: Without designing connection points, it can avoid the risk of clicking;
2. Durability: The power transmission components are not exposed and will not be corroded by moisture or oxygen in the air; There are no contact points, so there will be no mechanical wear or damage caused by jumping during connection and separation;
3. Convenience: When charging, there is no need to connect with wires, just place it near the charger, no need to use multiple power sockets, and there will be no multiple wires tangled.
Disadvantages of wireless charging solutions:
1. Slightly low efficiency: General chargers also have transformers, but the transformer structure composed of transmitting and receiving coils used for wireless charging is limited, and the theoretical transmission efficiency is lower than that of general chargers;
2. Slow charging speed: Nowadays, most products such as smartphones limit input power, so the charging speed is relatively slow;
3. High cost: Chargers require electronic circuits to drive coils, while power receiving devices require electronic devices to convert power. Both require coils and a high-frequency filtering circuit to meet electromagnetic compatibility, so the cost is higher than direct charging.
Since establishment in 2003, Golden Gagle has continued to foucus on R&D, design, produce and sales as one of the electronic components factory, the main products: all kinds of precision, mirco inductance coils, self-adhensive hollow coils, skeleton coils, hearing aid coils, antenna coils, RFID coils, sensor coils, all kinds of modules, solenoid valve, plastic accessories and all kinds of electronic components assembly, all kinds of high-frenquency voltages, filters, inductors, to provide customers with high-quality products and wholehearted service.
