3, so this function is only suitable for some charging occasions that are not in a hurry. While car owners may find it convenient to charge their phones in the car, they actually don't get much charge at that point on the drive to work. In addition, the requirements of wireless charging on the body material are also hindering domestic mobile phonesA big threshold for follow-up.

4, Apple wireless charger recycling, using magnetic induction charging technology, although still need to contact with the charger, but in fact is also the use of electromagnetic coil transmission power, the ceramic material on the back can achieve wireless charging. The metal body will affect the use of wireless charging, but Qualcomm is said to have introduced wireless charging technology that supports metal housing. The most mature and common wireless charging method is electromagnetic induction.

Why does my iPhone Magnetic wireless charge wobble

appearsThere are many reasons for this situation, which can be solved according to the following methods. It may be that the contact between the magnetic charging head and the charging cable is poor or the interface has been damaged, and a new magnetic charger needs to be updated. It may be that the charging port of the device is blocked by foreign objects, so it cannot be charged. Try to clean the charging port. The charging port or charging power chip of the device may be faulty. You need to take the device to the after-sales inspection and replace the corresponding component.

It is recommended to go to the official website consultation point for maintenance. This wireless magnet flash charger also has a 5mm thick magnet inside, which ensures that it can maintain enough suction for a long time. As we all know, the higher the charging power, the generationThe greater the heat, then if not timely heat treatment, the power of the wireless charging end will be greatly reduced, and the mobile phone will also trigger the battery protection mechanism because of overheating.

Apple's original magnetic wireless charger is not easy to damage a product, Apple launched wireless charging after the Apple 13 mobile phone series, convenient users for this charger or 10 points recognize the original price is more expensive, but the quality is really very good, not easy to damage, user satisfaction is still extremely high, I hope I can help you.

Both have their own advantages and disadvantages. Magnetic wireless chargingMore convenient, direct, gently close to magnetic charging; Wired charging is faster and can achieve PD fast charging, but it is relatively not so convenient. The Apple iPhone8 began to support wireless charging, and the iPhone12 was upgraded to MagSafe magnetic charging.

High safety: Due to the role of magnetic adsorption, the mobile phone is not easy to slip or shift when charging, reducing the risk of accidental falling. Protect the mobile phone: Because it avoids frequent plugging and unplugging of the cable, it can reduce the wear and tear of the mobile phone charging port and extend the service life of the mobile phone. High flexibility:Magnetic chargers can usually be adapted to a variety of different phone models and sizes, with high compatibility.

QI wireless charging standard for foreign object identification description

Wireless foreign Object Detect Wireless foreign object detect (FOD) function Under normal circumstances, there is a metal foreign object placed on the transmitter, will not cause fever wireless foreign object detect ; Heat occurs when a metal object is placed on the transmitting end and the receiving end is stacked on top. Because the electromagnetic field will generate eddy current on the foreign body of the metal, it will heat the foreign body of the metal, resulting in a dangerous meltdown of the shell.

Identify QI standard: Wireless charging currently has two major international mainstream industry standards. One is the QI standard of the Wireless Charging Alliance (WPC), and the other is the AirFuelAlliance. These two standards have strict certification standards for the energy, technical parameters, compatibility, and safety of wireless charging products.

Confirm blueWireless charging: Not all Bluetooth headsets support wireless charging, so first make sure that the wireless charger blocks your Bluetooth headset supports this feature.

Choose a wireless charger that meets the Qi standard: There are a variety of standards for wireless charging, the most common of which is the Qi standard.

Magotan wireless charging why does it show a foreign body?

The following is about the displayPart of the introduction of the Wireless foreign matter blocking Wireless foreign matter blocking : Eddy current effect: The ferromagnetic metal itself is a closed loop. When a ferromagnetic metal is placed in a changing magnetic field, the magnetic flux through this closed loop changes to generate an electric current inside the metal. The flow of this current inside the metal causes loss and causes the metal to heat up. This is called the vortex effect.

Analysis of the problem of foreign bodies in Magton wireless charging: Foreign bodies usually refer to magnetic metals Wireless foreign matter blocking , that is, magnetic substances. When such substances are in a change of magnetic field, according to the eddy current effect, an electric current is formed inside the metal, causing it to heat up. This means that when there is a magnetic substance on the wireless charging board, it may lead to a loss of energy, which poses a potential threat to the receiver and transmitter of wireless charging.
