1, wireless charger charging speed is slow, there are the following possibilities: 1, wireless charger wireless charging power itself is not large. 2, the wireless charging receiver of the mobile phone, the charging current supported is not large. It is recommended to change a high-power wireless charging board, such as a certain meter, which has more than ten coils, although it is not opened at the same time, the effect will be good.
2, the iphone wireless charging is slow, the reasons are as follows: because to take care of the cost, but also pay attention to security. Therefore, after testing and evaluation, 7:5W was finally determined to beThe new iPhone wireless charging is a safe and cheap solution, which is certainly much slower than the 15W wireless charging that can be supported now.
3, low charging efficiency Since it is for mobile phone charging, charging speed is of course the first, even if you can do the application of "wireless", but for the most basic requirements of charging speed can not be reached, then the experience will probably be a discount.
4, Tips: The power cord between the power plug and the wireless charger is best to use the original wireless charger, once there was a friend who stubbornly believed that the third party power cord quality is moreOkay, so the wireless charging of the phone is intermittent. Wireless charging has the requirement of the distance between the mobile phone and the wireless charging panel, so a very thick mobile phone protective case or back bracket will cause the distance to exceed the effective receiving range or "virtual charging" phenomenon.
5, the loss of components affects the internal resistance of wireless charging fast and slow components, and the conversion efficiency of the system is high. The selection of components such as triode with small internal resistance can greatly improve the efficiency of wireless charging. However, with low internal resistance, the cost will be relatively high.
1, W wireless flash charging vertical charger is plug and play, in the use of wireless charging, with the mobile phone standard charger connected to the device, and then the mobile phone left and right center vertical/horizontal screen on the base to achieve wireless charging, after charging the mobile phone removed, disconnect the power can be.

2, what is wireless flash charge Wireless flash charge is a wireless charging technology, which uses the principle of electromagnetic induction to transfer electricity from the charger to the deviceWithout the use of cable connection. This technology allows users to more easily charge without worrying about wire length and damage. At the same time, wireless flash charging can also improve the efficiency and speed of charging, so that users can fill the device more quickly. The working principle of wireless flash charge Wireless flash charge uses the principle of electromagnetic induction.
3, vivo wireless flash charging vertical charger use method is to put the wireless charging function of the mobile phone on the wireless charging board, the position should be placed, you can charge. Dual engine flash charging system with innovative dual charging chip and dual charging circuit, two sets of circuits at the same time power supply, bring faster and more stableIs the charge really faster than the Mi 8 cable?
The results of the 20W wireless flash enhancement test of the Mi 9 show that its charging speed exceeds the 18W wired fast charge, and even faster than the wired fast charge of the Mi 8. Lei Jun shared a comparison video in Weibo, taking the Xiaomi 8 as the experimental object, the two began to charge at the same time after running out of power, official data show that the Xiaomi 9 was fully charged in 1 and a half hours, and the Xiaomi 8 has completed 100% charging in 4 minutes.
Mi 9 supports wireless charging, charging power up to 20W. Mi 9 after using 20W wireless charging, one and a half hoursWith full charge, it is faster than the wired fast charge of the Mi 8. Therefore, Xiaomi calls 20W wireless charging "wireless flash charging". At the same time, the Mi 9 has passed the German Rheinland YUV safety fast charging system certification, which has greatly improved the charging safety.
Mi 9 20W wireless flash enriched test: Faster than Mi 8 wired fast charge With the progress of wireless charging technology, Mi 9 equipped with 20W wireless flash charge has shown good strength. Lei Jun confirmed in Weibo that the wireless charging speed of the Mi 9 is indeed higher than that of the ordinary 18W wired fast charge, and proved this view by comparing videos to smallMeter 8 as a test subject.
