Is wireless charging practical? Is wireless charging reliable

I feel that wireless charging is not necessary, and wireless charging also requires a wireless charger plug, which is not much different from ordinary chargers.

It depends on what it is, sometimes it is troublesome to have a lot of wires, but wireless ones are easy to break, it depends on the individual.

Summary. It's safe to get up close and personal with a wireless charger, so whether you're charging your phone overnight on your bedside table or working all day on your desk, you're safe. If your wireless charger is not connected to your smartphone or tablet, it will send a harmless signal to search for a wireless charging receiving coil, such as a smartphone charging coil.

Since the receiving coil (located in your smartphone) needs to be in contact with the charging base coil, avoid transmitting the signal into the surrounding air. When your smartphone actually makes contact with the charging base, the signal will be concentrated to the phone's receiving coil to start charging. Compared to a mobile phone connected to a mobile network, the entire wireless charging process emits much less radiation.

Hello, I am helping you to inquire about the relevant information and will reply to you immediately.

1. Trouble-free, you don't need to pay attention to the battery, and you don't need to plug in the mobile phone cable to play with the phone. You don't need to pull the string when you leave.

2. Battery maintenance: The characteristics of lithium battery are that it can be charged at any time, keep it in use, and not overshoot for a long time, but not discharge. If the handwriting is not idle, it will not be overcharged, mainly over-discharged.

The use of wireless charging is basically between 80% and 100%. Very good for battery maintenance.

3. Reduce interface loss: I have used 6P to 8P, and I can obviously feel that there is resistance at the interface of 8P, which should be waterproof. The waterproof properties will weaken with use. Generally, wireless charging is used to reduce the drag line to play with mobile phones, and the interface loss will be much smaller.

What is it?

Is it now possible to charge wirelessly.

What should I do if my phone won't charge wirelessly.

Can you turn on wireless charging for me.

1. Please check whether the phone is placed in the center of the back of the wireless charging pad. 2. When there is an inclusion between the mobile phone and the wireless charging pad, it may not be able to charge normally. 3. Please check the back cover of your phone.

If the protective case used is too thick and may hinder wireless charging, it is recommended to remove the case and try to charge it again. 4. Please use the original charger. If you use a non-original charger, it may not charge properly.

5. Connect the phone directly to the wired charger to see if it can be charged normally.

Please tell me if it's okay.

Infinite charging may not be charged due to irregular operation, or the charging equipment is out of power or damaged, or the infinite charging function of the mobile phone is damaged.

Wireless charging methods include electromagnetic induction, magnetic resonance, electric field coupling and radio wave transmission, etc., and most of the wireless charging of mobile phones uses the principle of electromagnetic induction.

In electromagnetic induction wireless charging, when the current of the power supply passes through the coil (the transmission coil of the wireless charger), a magnetic field will be generated, and other unenergized coils (the receiving coil on the mobile phone) will generate an electric current when the magnetic field is rented close to the mobile phone to charge the mobile phone. As shown in the figure below.

Advantages of wireless charging.

Safety: The design of no energized contact can avoid the danger of electric shock.

Durable: The power transmission element is not exposed, so it will not be eroded by moisture, oxygen, etc. in the air; There is no sign of collapse without contact, so there will be no loss caused by mechanical wear and flashover during connection and separation.

Convenient: There is no need to connect with wires when charging, just put it near the charger, no need to occupy multiple power outlets, and there is no trouble of multiple wires entangled.

Disadvantages of wireless charging.

Slightly lower efficiency: There are also transformers in general chargers, but the transformers composed of transmitting coils and receiving coils for wireless charging are theoretically slightly lower than those of general chargers due to structural limitations.

Slow charging speed: Due to the fact that most receiving devices such as mobile phones limit the input power, the charging speed is slow.

High cost: The charger needs to have an electronic circuit to push the coil, and the power receiver needs to have an electronic device for power conversion, both need to have a coil, and a high-frequency filter circuit is required to meet electromagnetic compatibility, so the cost is higher than direct charging.

The emergence of wireless charging technology has brought us a lot of convenience, we don't have to drag a line around anymore, just need to put the mobile phone on the table to be able to transmit, it has three principles, divided into electromagnetic induction magnetic field resonance and radio wave type. Electromagnetic induction refers to the alternating current in the primary coil, in which an electric current can be generated. At this time, the electrical energy will be convertedThe transfer from the transmitter to the receiver creates energy conversion, which is also the most common wireless charging method today.

The second is magnetic resonance, which is also a combination of a transmitter and a receiver. One frequency between the two devices needs to be adjusted to the same stage, because only then can they resonate. However, there is no way to commercialize this technology.

But it is characterized by the fact that it can truly realize the role of wireless charging technology, and the latest technology shows that it can light a light bulb from two meters awayIf you can receive the store energy in the air, then you don't need to carry a charger when you go out in the future, and you can charge it anytime and anywhere.

It is believed that in the future development of science and technology, this technology can mature and be applied to mobile phones. The most commonly used and more mature is radio waves, which are also composed of microwave transmitting devices and microwave receiving devices, and one of the advantages of this device is that it can better capture radio waves. And now the wireless fast charging technology is also more and more developedMost mobile phones support the Qi standard, which means that manufacturers will advertise in the profile that they support Qi wireless fast charging.

You need to have a wireless charging chassis and an 18 watt or 30 watt fast charger. The second is that the mobile phone needs to support this function in order to achieve the so-called wireless fast charging. Manufacturers are also developing this technology more and more rapidly.
