About "Wireless charging function does not work"

Check if the car model is compatible with the product. Please check if the car model is compatible before purchase.
Check whether the mobile phone is compatible with the product . 1.The wireless car charger meets the International Wireless Charging Consortium protocol (WPC1.2.4) QI standard, and supports charging of mobile phones that comply with the QI standard and have wireless charging function. 2.If the mobile phone does not support wireless charging, even if the wireless car charger is purchased, wireless charging cannot be achieved.
Check if the vehicle starts. First of all, make sure the vehicle has been started and the engine is in running condition.
Check if the cigarette lighter hole is good. Cars that are used a lot will have deteriorated wiring. Cigarette lighter wires that come off can cause the car's cigarette lighter not to power up, and it can also cause the wireless car charger not to work. Please have it checked and if it is determined to be a problem with the wiring then go to a workshop to have it repaired or replaced.
Check whether there is a mat in the wireless car charger slot that comes with the vehicle (whether there is a foreign object in the cigarette lighter hole). 1.Some thicker silicone mats or other non-conductive, non-magnetic permeable materials placed underneath the wireless car charger may impede or diminish the transmission of the electromagnetic field required for wireless charging, resulting in inefficient charging or failure to charge. 2.Ensure that there is no dirt or foreign matter in the cigarette lighter hole, which may affect the power-on effect.
Make sure the connector and the cigarette lighter hole are installed closely. When installing, please align the connector of the wireless car charger with the cigarette lighter hole, press slightly hard to insert it, if the vehicle comes with a wireless car charger slot, then the wireless car charger must be flush with the slot, and if the vehicle does not come with a slot, then ensure that the wireless car charger connector is fully inserted into the cigarette lighter hole. The two must be precisely aligned to avoid poor charging results or safety hazards caused by poor contact.
Check whether the indicator light of the charger lights up normally. 1.After inserting it into the cigarette lighter hole, observe whether the indicator light is on or not, and the green light proves that the product is fine. (Note: some wireless car charger indicator light brightness is dark, users need to look closer, we have asked the factory to enhance the indicator light brightness.) 2.If the indicator light does not light up, it may be that the wireless car charger itself is faulty, such as internal circuit damage, indicator light failure, etc.
Check whether the mobile phone is wearing a mobile phone case (if so, please remove it). Wearing a mobile phone case on your mobile phone may interfere with the normal operation of wireless charging, resulting in inefficient or unavailable charging. The material, thickness and design of the phone case may have an effect on the electromagnetic wave transmission required for wireless charging.
Check that the mobile phone is properly placed on the charger (do not place it upside down). Properly placing your mobile phone on the wireless car charger is one of the key steps to ensure that charging runs smoothly and that your device is kept safe. Be sure to follow the instructions on the manual and avoid placing your phone in an incorrect way for wireless charging.
Check for changes in your phone's charging symbol. Some mobile phones do not have obvious pop-up reminders when charging, which may make users mistakenly think that the phone is not charging. For this situation, users need to learn to observe some subtle changes on the mobile phone screen to confirm the charging status, especially pay attention to the changes in the battery icon in the upper right corner.

"High temperature during use", "USB not working" and other questions

Wireless charging process energy loss caused by heating. Wireless charging process heat can not be avoided, because the wireless charging process involves energy conversion between the electromagnetic, in the process there will be energy loss, these lost energy is mainly in the form of heat emitted, at the same time, the wireless car charger internal electronic components in the work of the heat will also be generated, which leads to mobile phone heating.
The heating caused by charging the battery inside the mobile phone. Whether it is wired charging or wireless charging, the battery inside the mobile phone will generate some heat during the charging process.
The coil is not aligned to lead to heat (or position is not enough to put the coil is not aligned). 1.When the internal coil of the mobile phone is not aligned with the wireless charging coil, part of the energy can not be effectively transferred, and this part of the energy will be dissipated in the form of heat, resulting in the heating of the mobile phone and wireless charging. 2.When the position is not enough to put the mobile phone coil can not be aligned, please remove the clutter/block on top of the mobile phone.
Heating caused by extreme environment. Using wireless charging in a hot or humid environment will make it more difficult to dissipate heat from the phone. The heat inside the phone can't be emitted to the external environment in time, leading to an increase in the temperature of the phone.
The heat dissipation function of the mobile phone itself is not good. 1.Some mobile phones may use lower specification components in the design and quality of the thermal sensor (or known as temperature sensor) due to cost considerations or design flaws, resulting in less sensitive sensing. 2.If the mobile phone has been dropped, the internal heat sensor (or temperature sensor) may have been damaged by the impact, resulting in its inability to sense the temperature properly or inaccurate sensing of the temperature. 3.If the heat dissipation function of the mobile phone itself is not good, then no matter wireless charging or wired charging will have the problem of high temperature.
Please note: wireless charging process heat is the result of a number of factors, the above three factors (wireless charging process of energy loss, the phone's internal battery charging heat and the coil is not aligned due to the loss of energy) the heat generated by the build-up of mobile phones and wireless car chargers in the internal and external, it does lead to the temperature of their rise (charging for a period of time after the heat), at this time the temperature of the hand is about 40 degrees Celsius. The hand temperature is around 40 degrees Celsius (104 degrees Fahrenheit).
About the USB port can not be used. 1.QC3.0 port is only applicable to Apple mobile phones 2.5V/2A port is only applicable to Android mobile phones and some Apple (latest generation only) 3.When using the USB port, please choose the appropriate jack for plugging and charging according to your mobile phone, in order to avoid unnecessary misunderstandings and disturbances. 4.There may indeed be cases where the USB port is not oriented correctly due to a variety of reasons (including factory assembly errors). It is recommended to try both USB ports to make sure which port or hole is correct and working properly. Please contact me, I will provide you with an effective solution.5.Make sure there is no problem with the cable, if the cable is damaged, broken, poor contact or mismatched specifications, it will not be able to charge properly.
The phone will rock from side to side while driving and will not charge. The side-to-side shaking is due to the mismatch between the protruding lens of the mobile phone and the non-slip adhesive ring of the charger. The camera modules of modern smartphones are getting bigger and bigger, especially high-end models, which may lead to the back of the mobile phone being uneven, especially the lens area is obviously protruding. When the phone is placed on the wireless car charger, the protruding part of the lens does not fit perfectly with the non-slip adhesive ring of the car charger, which causes the phone to shake due to the bumps during vehicle driving.
The USB port is lower and harder to plug in. We are trying to adjust the position of the USB port on the wireless car charger to make it easier to plug and unplug and more ergonomic and user friendly, but this may take some time.
Built-in cooling fan is noisy and the fit between the USB cable and the port is too tight. It may be that the fan or radiator parts become loose, resulting in abnormal noise when running, and the factory has been specially accounted for to pay attention to this when assembling, and make it as quiet as possible. We are still improving the product design and assembly process, please trust us and give us time.

"Is it fast charging" "Too slow for efficiency" and other questions

Is this car charger a fast charger? The charging efficiency is too slow. 1.Currently on the market mainstream car wireless car charger power up to 15W. 15W wireless charging power in the field of car wireless charging has belonged to a higher range, but purely from the point of view of power, it is not directly equivalent to fast charging. The higher the charging power, the more powerful the heat will be, so it can not simply pursue the charging speed. 2.If the user needs fast charging in a short period of time, then the 15W car wireless car charger may not be able to meet its needs; but if the user does not have too high requirements for charging time, then the 15W car wireless car charger has been fast enough. 3.Charging efficiency is too slow" this point of view, depends largely on the subjective feelings and needs of individuals. Different people's requirements and expectations of charging speed may vary greatly. 4.For users who need fast charging for daily use or emergencies, 15W wireless charging may indeed seem inefficient. Especially compared with the current wired fast charging technology, wireless charging still has a certain gap in power and charging speed. 5.However, for some users who are less interested in charging speed, or who value the convenience and neatness of wireless charging more, 15W wireless charging may be enough to meet their needs. They may pay more attention to the convenience brought by wireless charging and reducing the nuisance of tangled wires. 6.The phone will show a faster charging speed during the charging process, especially when charging from 5% to 50%, but then the charging speed drops significantly and becomes hot and the charging stagnates when it reaches about 60%. This is due to the phone's battery protection mechanism, which is used by many mobile phones to automatically reduce the charging speed to prolong the life of the battery and to prevent it from overheating when it is close to being fully charged. This mechanism is known as trickle charging or maintenance charging and it helps to ensure that the battery is not overcharged when it is full, thus protecting it from damage. 7.The original charger that comes with the car is even slower, only 5W. 8.The highest wattage of on-board wireless car chargers on the market today is 15W at 12V (the car's power is 12V). Wireless charging technology must be designed and implemented in strict compliance with safety norms and standards to ensure the safety of vehicles and passengers. 9.Excessive charging power may put too much burden on the car battery, resulting in heating, accelerated aging and even damage to the battery, thus affecting the safety and service life of the battery. 10.Unlike home chargers, the main function of a car charger is to provide continuous power support for mobile phones while the vehicle is in motion, ensuring that the device does not run out of power and interrupt use. It is not designed to achieve fast charging, but to meet the driver's basic need for mobile phone power during long journeys or daily commuting.
The cover above the wireless car charger bay will not close (only for vehicles with a cover). 1.When the wireless car charger's vehicle charging connector is not fully inserted into the cigarette lighter hole, the cover above it may not close properly due to the high position of the wireless car charger. 2.The mobile phone cannot close the cover in any case during wireless charging.
Can the wireless car charger and cup holder be used at the same time? (Only for vehicles with their own bay and with a cup holder). 1.When the mobile phone is charging wirelessly, the cup holder cannot be used because the length of the mobile phone will stretch to the cup holder position. 2.When not charging, the cup holder can be used, but the charger needs to be removed and the following conditions should be met: 1. The cup should be screwed tightly with the lid, to prevent liquid from spilling onto the wireless car charger and causing damage. 2. The cup should not be too big to prevent it from pushing against the wireless car charger and causing it to loosen, resulting in a bad connection.
Can it be plug and play? Or do I need to wait until the vehicle is started to use it? You need to start the vehicle and power it up before you can use it, after the vehicle is started, it supports plug and play.
Will it hinder the signal of the smart key? 1.After power on, the coil of the wireless car charger will generate electromagnetic induction, which will cause interference to the smart key affecting the normal use, such as not being able to identify the key, not being able to start the vehicle, etc.2.In order to avoid potential interference problems, be careful not to place the smart key near the wireless car charger, at least 30 cm away. 3.Wireless car chargers all have this problem.
