For the human body: Wireless charging technology is safe and harmless to the human body. The resonance principle used by wireless charging is magnetic field resonance, which is transmitted only between coils resonating at the same frequency, and other devices cannot accept the band, in addition, the magnetic field used by wireless charging technology is itself harmless to the human body.
In fact, it is certain to tell you that the harm of wireless charging to the human body is very small, almost negligible. This is just like our usual use of Wi-Fi, mobile phones, televisions and other electronic products, andWe also do not exist between the transmitter and the receiver the radiation level is small, and the main frequency absorbed by the human body is not consistent with the charging frequency, so we can not worry about the harm of wireless charging.
Conclusion: Wireless chargers do produce electromagnetic radiation, although the value is usually small, but should be wary of its possible cumulative effect. With the popularity of wireless charging technology, users are exposed to more and more radiation sources in daily life, such as mobile phones, computers, WiFi, etc., and long-term accumulation may have an impact on health. Wireless charging technology and controversy With the development of mobile Internet, wireless charging functionThe rise has led to discussions about electromagnetic radiation.
Does wireless charging technology radiate the human body? Does it cause cancer? Tests have proved that wireless chargers can indeed produce electromagnetic radiation, but the value is relatively small. Now users are exposed to more and more radiation: computers, tablets, mobile phones, WiFi, televisions, microwave ovens... The cumulative radiation value is very high, and if the user lives in such a high radiation environment for a long time, it may cause serious harm to the body and mind.
From the theory, wireless charging technology is safe and harmless to the human body, the resonance principle used by wireless charging is magnetic field resonance, onlyIt is transmitted between coils that resonate at the same frequency, and other devices cannot accept the band, and the magnetic field used by wireless charging technology is itself harmless to the human body.
1, the battery capacity of Yubo charging treasure is 20,000 ma, which can support a large 25W fast charge power, and meet the regulations of bringing on the plane, which can be safely carried on board. Its 20,000mah body is equipped with a power input port and two power suppliesThe output interface can charge two mobile phones at the same time. However, the disadvantage is that the weight of 20000 MA is heavy, and it is not very convenient to carry.
2, Momis is a vibrant and dynamic Hong Kong brand, Momis charging treasure whether it is shape, color matching, functional application and characteristic packaging are unique style, enthusiasm, vitality is the logo of this brand, so Momis charging treasure is also loved by young people.
3, the best ten charging treasure brands are as follows: First: Pinsheng PISEN is a famous digital 3C accessories supplier in China, focusing on mobile power supply and digital 3 for many yearsC accessories, cloud routing and other intelligent mobile peripheral equipment O2O Internet enterprises, its products are widely trusted by consumers, charging treasure has been the proud work of Pinsheng.
4, Nank South Carolina wireless charging treasure POW2 Nank South Carolina wireless charging treasure with its excellent quality and reasonable price has been warmly welcomed in the market. The brand is strictly controlled in the selection of materials and workmanship, and its product details can be seen. While maintaining a balance between capacity, volume and beauty, Nank also focuses on practicality, such as 18w strong output and 10W wireless fast charge.
Not enough. For example, the previous 5 watts of wireless charging ah, to the last 5 watts of power is relatively low, I do not know wireless charging and wired charging is different, although the standard wattage is relatively high, but it will be greatly discounted when it is really used.
First is the charging efficiency, the current wired fast charge has been able to achieve 30W-40W power, and even 55W ultra-high fast charge technology is under development, in contrast, wireless charging is limited by existing technology, the power is generally small, Apple is currently only 5W, the speed of wireless charging can not keep up with mainstream demand; The second is the price, the price of wireless charging is higher than that of wired chargingPrices are generally higher.
At present, it is not hot, and only high-end mobile phones are equipped with wireless charging function, which can be imagined that the cost is not low. For now, the application of low-end machines is obviously not yet ripe. Wireless charging technology does not use charging lines at all, but uses magnetic fields to charge devices, and is inspired by wireless power transmission technology.
May wireless charging this function sounds like a very powerful function, after all, wireless must be a general trend in the future, but the current wireless charging is not the wireless charging we imagine.Recent years, wirelessFast charge has become a hot word, especially on the new flagship model this year, wireless fast charge has become the standard, no wireless fast charge in the status is half the difference. But before, the wireless charging in my eyes was a chicken rib. Food is tasteless, but it's a pity to throw away.
Wireless charging is not a standard feature: Redmi note series mobile phones are mainly aimed at the low-end market, in order to maintain cost effectiveness and reasonable pricing, often not equipped with wireless charging function. Most of the Redmi note series phones currently on the market focus on providing excellent battery life and performance, rather than wireless charging. Cost and market of wireless chargingDemand: Wireless charging technology requires additional hardware support, which increases the manufacturing cost of the phone.
Wireless charging hurts the battery more than wired charging. As long as it is charging will cause damage to the battery bright wireless charging Bright wireless charging , but wireless charging and wired charging are compared bright wireless charging If Ming energy wireless charging , wireless charging is more damaging to the battery, because it will generate more heat when wireless charging, and the heat generated is relatively large. Whether the line charge charges the battery is controlled by the internal circuit of the mobile phone, and the initial voltage for the normal operation of the internal control circuit of the mobile phone is provided by the battery.
Wireless charging hurts the battery more than wired charging. In fact, we all know that as long as it is charged, it will cause damage to the battery, but wireless charging and wired charging are carried outIn contrast, wireless charging is more damaging to the battery, because wireless charging will generate more heat, and the heat generated is relatively large.
Wireless chargers have an impact on battery life. The use of wireless chargers has an impact on battery life mainly reflected in the following aspects: First, the wireless charger generates current through the electromagnetic field to charge the device, and its charging method may be slightly less efficient than wired charging. This means that some heat may be generated during the charging process.
