Shuobide is a professional manufacturer of wireless communication terminal antennas, the main business is the development, production and sales of wireless communication terminal antennas.
1, this situation buy wireless charging coil magnetic disc reasons are as follows buy wireless charging coil magnetic disc : First of all, the magnetic phone case will interfere with the wireless charging coil of the mobile phone purchase wireless charging coil magnetic sheet , affecting the charging effect. The wireless charging coil of the mobile phone needs to be accurately aligned with the coil of the charger to achieve charging, and the magnetic phone case will change the shape and weight of the mobile phone, making the wireless charging coil and the coil of the charger cannot be accurately aligned, resulting in poor charging effect.
2, 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 could also be a foreign object in the charging port of the deviceUnable to charge due to blocking, try to clean the charging port. It may also be that the device charging port or charging power chip is faulty, and it is necessary to carry the device to the after-sales inspection and replace the corresponding components. Magnetic charger as a new charger, it is mainly the use of magnets can absorb magnetic metal characteristics.
3. The intermittent power supply of the magnetic access control system may be caused by the following reasons: Loose power cable: Check whether the power cable of the access control system is loose. If yes, reinstall the power cable. If the power cable is in poor contact, check whether the power cable connector of the access control system is clean and tidy, and ensure that the power cable is connected to the connectorGood contact between.
Connect the standard charger and data cable of the mobile phone to the wireless charger, and then put the mobile phone in the center position of the left and right of the wireless charger base, you can realize wireless charging, the indicator light will have a breathing effect, 5 seconds later, plug and play, convenient and quick.
Wireless charging usage: Connect the phone's standard charger and data cable to the wireless charger, and then put the phone in the center position of the left and right of the wireless charger base, wireless charging can be achieved, indicatingThe ferrite diskette should be as thin as possible. However, the properties and thickness of magnetic materials require careful design. This is because if the magnetic sheet is too thin, it will cause magnetic saturation problems.
3, please check the back shell of the phone. If the protective phone cover used is too thick may hinder wireless charging, it is recommended to remove the phone cover and try to recharge. Please use the original charger. If you use a non-original charger, you may not be able to charge normally. Connect your phone directly to the wired charger to see if it can be charged.
After opening the back cover, you can see the wireless charging coil and NFC of Millet 9, of which the 20w wireless charging coil was praised by Wang Teng Ben "especially cool, a look at it feels very valuable!" . However, this huge wireless charging ring also occupies a considerable amount of space inside the fuselage. Next, it removed the wireless charging coil and saw the battery.
Xiaomi's wireless charger can charge Apple 11, because it is achieved through the wireless charging ring, and does not need to adapt to Apple's charging interface, so Apple's mobile phone can also use other brandsWireless charger. Not only can charge the Apple 11, but also with different charging heads can achieve slow charge or fast charge, up to 5W charging power.
The solution of the brand wireless charging ring is broken and not charged is as follows: Use the original charger and data cable to connect the power to charge. For the mobile phone with removable battery, you can shut down and remove the battery, use a cotton swab to clean the battery contact and the mobile phone charging interface. Bring the purchase invoice, repair card and machine to Samsung service center for inspection.
can the _ hope corrects only _FC to cause damage to its magnetic principle and magnetic chargeLike electrical appliances, because the original iron inside the phone is very little, the iron original is not the main original, the magnet does not have much impact on it, as long as it does not affect the use, it will not affect the performance.
No If the damage is small, it doesn't matter. Because there's a black tape on the outside. It's not that easy to break inside. If you pry it, it'll be fine. It'll just affect the charge. It has no effect on other functions of the phone. Before use, we should check whether the structure of the coil is strong, whether the turn is loose and loose, whether the lead contact is loose, whether the magnetic core rotation is sensitive, and whether there is a slip button.
