Millet vertical air cooled wireless charger price is 199 yuan, millet car wireless fastThe charging price is 139 yuan. Recently, Xiaomi's 5G era charging technology media communication conference held in Beijing can be said to be brilliant, high-profile display of the world's first 30W super wireless flash charging technology, and in the follow-up millet 9PRO conference also released related accessories products, 199 yuan vertical air-cooled wireless charging base, or very worth starting oh.
Of course, wireless chargers also have high-power models, taking a wireless charger from Huawei as an example, the maximum charging power can reach 50W, but the price of nearly 300 yuan is not cheap, even the charging power is only 15W typeIt's 92 yuan, too.
Reference price: 278 Charging protocol: PD charging method: Wireless Belkin This wireless charger is certified by QI wireless charging protocol, providing the largest 15W wireless fast charge, such as Android Huawei, Samsung and other mobile phones wireless fast charge, for Apple can only support 5W charging.
At present, the price of smart phone wireless chargers on the market has from less than 100 yuan to thousands of yuan, mainly depending on your needs.
The iphone6 original charger costs 149. The design of this power adapter is super compact and can be implemented at home.
In fact, the big brand of charging treasure is not only Xiaomi, but also other big brands, such as Huawei, Bysi, Philips, Roma Shi, Pinsheng, etc., all belong to some big brands in the field of charging treasure. One of the more cost-effective, and more distinctive, is an Apple Magsafe magnetic wireless charging treasure.
BSI magnetic wireless charging treasure four color options, pre-sale price is 109 yuan. Bsi magnetic wireless charging treasure uses 6000mAh custom grade battery, the capacity is double that of Apple's original factory, built-in Qi magnetic wireless charging module, supportiPhone 1iPhone 13 series, can also be used with case.

Wireless charging, power digital display, more importantly, the function is good. Featherbo charging treasure. Featherbo charging treasure fast charge A2, ultra-thin.
1, official expensive. Official noneLine charging is very expensive, but you go to a treasure search, big times big times dozens of dollars, and there are many manufacturers of wireless charging, I think there is no need to buy hundreds of thousands, buy a few dozen try to feel on the line wireless charging expensive .
2, slow charge, do not consider the power transmission loss, seems to be comparable, and radio charging, often more than wired charging, more "waste" wireless charging expensive ; Fast charge point of view, from the power level, wired fast charge in the high power frequency band, "sling wireless". Parking accuracyIn principle, the relative position between the car end and the ground end coil will significantly affect the charging power and efficiency. It is unrealistic to expect users to park their cars with centimetre accuracy every time.
3, electric vehicle wireless charging technology has become a popular electric vehicle to become the mainstream, the problem of battery life has not stopped, in order to solve the battery life problem, the various car companies have also tried their best to find a way to solve this problem, in addition to the power change and fast charge, in fact, there is a different way, that is, road charging, Let the car run along the road.
4, causeHigh performance and high usage. General single-cylinder car air pump disadvantages are insufficient air pressure, long inflation time, larger car inflation is more difficult, but the price will be cheaper, and the two-cylinder air pump although the price is slightly more expensive, but the air pressure is enough, inflation fast.
5, high-power wireless charging is often resonant, most of the wireless charging of electric vehicles are used in this way, by the power supply equipment to transmit energy to the electrical device, the device uses the received energy to charge the battery, and supply the device's own operation needs. Because the charging device and the electrical device transmit energy through the magnetic field, there is no energy between the twoThere is a wire connection, so the charger and the electrical device can be done without conductive connectors exposed.
6, at the iPhone 13 conference, Apple did not launch a new magnetic wireless charger, so for iPhone 13 users, want to use magnetic wireless charging, the official here only last year's magnetic wireless charger can choose. So the charging head network planned this content to see how the Apple MagSafe magnetic wireless charger will change when charging the iPhone 13 Pro Max.
2, due to the heating problem in the electromagnetic conversion process, taking into account the safety of electricity and other factors, manufacturers have to control the power. This is also a reason for the gradual disappearance of wireless charging. After all, wired fast charge has developed to 120W, and the fast charge carried by most mobile phones is more than 60W, which has surpassed the wireless fast charge, so wireless charging has gradually opened the gap with wired fast charge because of the technical requirements of the equipment.
3, in addition to the trouble of charging, wireless charging also has a serious defect,That is, the charging efficiency is too low (early products). There is also a heating problem in the electromagnetic conversion process, taking into account the safety of electricity and other factors, manufacturers have to control the power. 4, because there is a heating problem in the electromagnetic conversion process, taking into account the safety of electricity and other factors, so in 2021, China's Ministry of Industry and Information Technology issued a technical requirement for wireless charging equipment, which has a clear provision: wireless charging rated power shall not exceed 50W. In order to comply with this regulation, manufacturers have to control the power. This is also a reason for the gradual disappearance of wireless charging.
5But wireless charging technology is a new type of charging technology, to the wireless charger of Maiyuan technology, many people will worry that wireless charging technology will be like the original Wi-Fi and mobile phone mast just appeared, in fact, the technology itself is harmless. Wireless charging technology uses magnetic resonance to transmit electrical energy in the electric and magnetic fields between the charger and the device, and the coil and capacitor form a resonance between the charger and the device.
6, so the battery life of iPhone XS Max is certainly not as good as some Android flagship, so if you plan to buy this phone, the author suggests buying a wireless charging boardClass time with use with charge; If you go out, bring a power bank in case you need it. Of course, the battery life of the iPhone 11 Pro Max is very big, the author's colleagues are useful, often to get off work there are 50% of the power, which completely solves the power anxiety.
1, there are reports that the introduction of wireless charging has caused heating problems in the new machine, but Apple seems to have found a solutionPlan. According to Kuo Mingchi, in order to cope with the poor heat dissipation of the glass case, the iPhone 8 May add graphite sheets inside to ensure that the 3D Touch module does not overheat and affect performance. 2, in the design of the iPhone 8, the introduction of wireless charging has brought a challenge: because wireless charging may lead to increased heat, and the glass case of the iPhone is not conducive to heat dissipation. To solve this problem, Guo Mingchi revealed that the new machine will have built-in graphite sheets to enhance heat dissipation performance and prevent the 3D Touch module from overheating and affecting its normal operation. Meanwhile, sources point out that allThe newly designed iPhone 8 could cost more than $1,000.
3, the biggest drawback of Apple x: wireless charging, cancel the interaction of the Home button, the price is too expensive. First: Awkward wireless charging. As we all know, Apple's latest iPhone8 and iPhoneX this year can support wireless charging this seemingly lofty feature. 4, take iOS11 system as an example, Apple 11 support wireless charging, Apple released this year three new iphones support wireless charging, but wireless charging accessories need to be purchased separately, there are on the marketMany Qi certified chargers are available. The iphone11 is a mobile phone released by Apple Inc., which was released on September 11, 2019. The iphone11 features an anodized aluminum and glass design, an A13 Bionic chip, and an ultra-wide-angle camera that supports 2x optical zoom.
5, so far, all Apple models released after iPhone 8 support 5W Qi wireless charging, if you want to achieve 15W magnetic absorption wireless charging on the iPhone 1114 series, you need to choose Apple's official MagSafe magnetic absorption wireless chargingElectrical or third-party magnetic absorption wireless chargers with "MFM" certification. Not to mention, the surrounding charging accessories are also very expensive.
