This article to talk about the domestic wireless charging power limits, and now wireless charging the maximum number of watts corresponding knowledge points, I hope to help you, do not forget to collect this site. < / p > < h2 > the article directory list: < / h2 > < ul > < li style = 'margin - bottom: 3 px; list-style: none'>1, Wireless charging 500W is OK
1, this charge is not 500 watts. Generally speaking, the power of wireless charging is relatively low, the power is usually between 5 watts and 15 watts, if the power of wireless charging is increased to 500 watts, it will produce high electromagnetic radiation, which will produce human healthBad effects. At the same time, it will also produce high heat, causing fire and other safety hazards.
2, HUAWEI FreeBuds 3 Support wireless charging up to 2W power.
3, it is the first generation of mobile phone wireless charging, the technology is mature, but can only be single-to-single short-range charging (qi standard, within 1cm, within 5 watts), and can not be similar to WiFi single-to-multiple charging.
4, Qi wireless charging system consists of a base station and mobile devices, the base station is the charging base we often see, the mobile device is the mobile phone through the principle of electromagnetic induction charging>
The Ministry of Industry and Information Technology stipulates that the power of wireless fast charge must be less than 50 watts, there are such requirements in the end why they are not clear, but they know that the power of this charge is not because of the reason of radiation, because radiation is everywhere, all the time, and not all radiation will have an impact on the human body.
To be precise, split sales, standard to separate retail, this is contraryLaw, because this makes the commodity can not achieve its normal use, only with accessories to normal use, in order to be the product itself is fully functional, so these accessories are necessary, must. First of all, the back of the hand can help children develop a kind of self-control ability, which is very important for their future growth. In kindergarten, children often need to wash their own hands, dress, eat, etc., which they need to do on their own, and the back of the hand can help them better focus and master their behavior. Secondly, the back of the hand can also help children avoid accidentally putting food or other food when eatingGet objects on your face or mouth.
1, wireless charger how to choose 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.
2, so when we choose a wireless charger, it is best to chooseChoose a product of the same brand and manufacturer, for example, if you choose an Apple mobile phone, then use an Apple wireless charger. In addition, we should also understand the charging standards of wireless chargers, because there are different ways of charging standards, and there are probably two kinds now, so it is also very important to choose which one is good.
3, protocol compatibility Huawei's SuperCharge vertical wireless charger set, to ensure seamless connection with their own and compatible devices, pay attention to the phone's charging protocol, such as Huawei, Apple or Xiaomi exclusive agreement. Charging area with convenience Green Link magnetic wireless chargingIts large charging area design allows the mobile phone to be placed more freely, adding convenience to your life. Make sure your choice fits your everyday usage scenario.
The current mainstream wireless charging power standard is 10W, which corresponds to the 5V2A charging specification. The wireless charging power supported by Apple phones is also generally in line with this standard. Some devices may support lower power, such as 5V5A, corresponding to a 5W charge rate. In contrast, the power of wired charging is usually around 1Around 8W, the speed of wireless charging is really slow.
Taking iPhone13pro as an example, Apple 13pro built-in lithium-ion rechargeable battery, can be wireless charging, wireless charging power up to 15W, can support Qi wireless charging and MagSafe magnetic wireless charging. Charging via a USB connection to a computer or a power adapter is also fast, with a 50% charge in about 30 minutes, using a power adapter of 20 watts or more (available separately).
According to the actual test, the wireless charging power of the iPhone X is 5W. This amountIt is the same as the maximum power supported by the iPhone 8/Plus when charging, and only half the maximum power of the new Qi 2 standard 15W. It is worth noting that although most mobile phones and new iphones today use the Qi wireless charging standard, and its latest version 2 supports a maximum of 15W charging, Apple did not choose the latest version, but chose version 1.
iphonex wireless charging has a maximum charging power of 5W. Users buy chargers according to the fast charge supported by the mobile phone to quickly charge, iphonex wireless charger power is large and small, about 10 power consumptionAbove W. Wireless charging technology (English: Wirelesschargingtechnology; Wirelesschargetechnology is derived from radio energy transmission technology, which can be divided into two ways: low-power wireless charging and high-power wireless charging.
System: iOS 11, iphone13 wireless charging power is 15W. Apple 13 wireless charging uses MagSafe magnetic charging technology, and is compatible with existing devices that support the Qi standard, and the maximum power of the Qi charger is 5W, which is the same as the previous Apple handThe machine is supplied with the same specifications.
Applicable brand model: iPhone8; System: ios14; Apple 8 wireless charging power is 5W, support wireless charging. The iPhone 8 is available in 64GB and 256GB versions. The Apple 8 is equipped with two performance chips, two performance cores, four high-performance cores, and the processor is A11.
1,And just recently, the Ministry of Industry and Information Technology has issued a provisional regulation, its full name is "Wireless charging (power transmission) equipment radio management interim provisions (draft for comments)", the provisional provisions on the wireless charging rated transmission power requirements is less than 50W.
2, the Ministry of Industry and Information Technology stipulates that the power of wireless fast charge must be less than 50 watts, there are such requirements in the end why they are not very clear, but they know that the power of this charge is not because of the reason of radiation, because radiation is everywhere, all the time, and not all radiation will have an impact on the human body.
4, but just now, the Ministry of Industry and Information Technology suddenly came out of new news. It is said that the power of mobile wireless charging equipment will be less than 50W from next year, which seems to be reflected from the sideWireless fast charging technology for mobile phone products will be limited. Mobile phone wireless fast charge may be the highest will also be fixed at 50W, of course, there is certainly a reason for such restrictions. 5, so I continued to dig deep, only to find that not long ago, the Ministry of Industry and Information Technology issued a regulation: mobile and portable wireless charging equipment rated transmission power requirements do not exceed 50W. Of course, this regulation has not yet been officially implemented, although it is tentatively scheduled to be officially implemented on January 1, 2022; However, it is still the stage of "soliciting opinions", which means that it is possible to not land or modify the standard in the future.
For consumers, although the use of the Qi2 wireless charging protocol in China is subject to certain restrictions, they can still choose wireless charging products that meet the regulations to ensure the compliance of the equipment and the safety of use. At the same time, we also look forward to the continuous development and innovation of wireless charging technology to bring consumers a more convenient and efficient charging experience.
Qi2 charger has many advantages. First, it does not require a physical connection, so it is much easier to use. The user simply will receive the devicePut it in the inductive area above the charger, and you can start charging. Second, wireless charging can avoid wear and damage caused by plugging in and out of the charging plug. Innovative and efficient charging technology of Qi2 Charger: Qi2 charger uses advanced electromagnetic induction technology to achieve efficient charging.
Qi2 charging devices can be aligned and charged faster using magnets, just like existing MagSafe accessories. Compared to the previous Qi standard, Qi2 uses magnetic power profile technology, which claims to ensure the perfect match between the device and the charger, thus improving energy efficiency. Qi2 will support the industryDeliver faster wireless charging technology while ensuring that the charging process is always safe and does not shorten battery life or damage the receiver.
Qi2: Backward compatibility The Qi2 charger maintains backward compatibility with Qi devices, enabling wireless charging with the Qi2 charger even if older devices cannot take advantage of higher power output or magnetic alignment. Qi2: Simplify the charging process Qi2 solves the wireless charger alignment problem with magnets and improves the charging efficiency. Users no longer need to search for the best charging location, saving time and effort.
QI2 brings to the userThe biggest difference in experience is that the use of QI2-certified wireless charging devices can provide a 15W charging experience for devices that support QI2. WPC sees QI2 as a significant opportunity in 23/24. Qi2 is a new enhanced wireless charging standard developed by the WPC Wireless Charging Alliance in 2023.
