How does the NTTM1 increase the charging base to avoid charging concerns, wireless charging can not only charge on the device, but also charge the charging base, and charge when put, more convenient. It is also equipped with a magnetic charging cable. It perfectly solves the problem that many parents worry that the elderly will not charge and worry that the children will plug in the charging port.
Chaoji Niu intelligent AI rereader is very portable, there is a WiFi version and a 4G version that can make calls. It is similar to the repetition machine used in childhood, which can be repeated sentence by sentence and A-B repetition, so that we can follow and correct the sound. Android's color screen is better than a traditional black and white copy reader. The intelligent AI rereader has rich resources, including textbook synchronization and expansion resources, such as graded English reading and enlightenment resources.
Chaoji Niu intelligent AI rereader is relatively small and easy to carry. It comes in two versions, a WiFi version and a 4G version that can make calls, which is a feature of this modelIt's the equivalent of the rereaders we used when we were kids. Compared with the point reading pen, it can repeat sentence by sentence, and can also repeat A-B, so that we can follow and correct the sound. Android still has a touchable color screen, which is much better than a traditional black and white copy reader.
Unsurprisingly, the waterproof came, after checking that it actually reached IPX5 waterproof, the IPX5 waterproof test standard on the Internet is described as "spray water, spray water in all directions to the shell has no effect, water flow rate 15L/min, test time 3min", this is good, the child is naughty, accidentally sprinkling water in the super memory cow above nothing; setIf you accidentally drop it in the basin, it doesn't hurt to remove it quickly. The advantages of magnetic charging are obvious, and the charger can be fixed to the body with one hand.
Super memory cow experience: Speaking of early education machine, learning machine, people always feel that as long as they can meet the singing, reciting poetry, rereading is enough. But in fact, the choice of learning products should meet the needs of children at each stage. Cattle listen to super remember cattle, to meet the whole stage of children's hearing needs. We often find a phenomenon, there are always some students in the class "recognize the teacher."
When wireless charging, it is normal for the phone to heat up, but overheating can be dangerous. Wireless charging technology uses the principle of magnetic coupling to transfer power between the transmitter and the receiver. In this process, part of the electrical energy will be converted into heat, causing the phone and charger to heat up. This is a common phenomenon of wireless charging easy wireless charging , does not mean there is a danger.
No. Car wireless chargers usually adopt a variety of safety protection measures, such as overcurrent protection, overheat protection and short circuit protection, to ensure their safety during normal useAnd the car wireless charger does not contain the battery original, under normal circumstances, the car wireless charger will not explode because of the high temperature in summer.
The answer is: There will be harm, shorten life. We all know the characteristics of lithium batteries, lithium battery operating temperature is generally 0-40 ° C, if long-term in a high temperature state of 60 ° C, it will damage the battery. In fact, there are so many fundamental reasons for mobile phone wireless charging fever, know the reason, you can choose a more suitable product, rest assured that the fun of wireless charging: Option selection.
Wireless charging this technology is really becoming more and more mature, the wired charger has the function of super fast charging, and the wireless charger now also has this function, many people who have used wireless charging technology will find that the mobile phone and the charging board are hot when charging, they feel very worried, after all, the mobile phone temperature is too high may cause an explosion.
Temperature control circuit. General wireless chargingThe program will have a temperature control circuit and NTC thermistor, this function is mainly to prevent the heat generated by the circuit in the process of working too high, burn components, etc., can also control the power components after generating too much heat, reduce the power, thereby reducing the temperature. Selection of heating components. qi standard wireless charging is originally the use of electromagnetic induction, generate current, promote the circuit work.
If you are conducting wireless charging, because there will be energy loss in the wireless transmission process, and then generate a certain amount of heat, there will be a phenomenon of heat when wireless charging, this is normal.
Mobile App fault Sometimes some apps run abnormally, which will occupy a large amount of memory and cause the CPU to run with a high load. Cases and other coverings With certain cases may affect the heat dissipation of the iPhone and cause the phone to become hot.
Hot wireless charging mobile phone is a normal phenomenon. In the process of wireless charging, the hot mobile phone is the result of a variety of factors. The following will explain in detail why the mobile phone will be hot when wireless charging from the working principle, energy conversion efficiency, mobile phone heat dissipation design and use environment. First of all, the working principle of wireless charging involves electricity
