Now, wireless charging devices are becoming more common, including NOKIA's Lumia parts, Nexus 4, and so on. All kinds of new mobile phones that are about to be released will be expected to be equipped with qi wireless charging.

The advantage of wireless charging is obvious: getting rid of the troublesome charging line is more neatly, no power socket on the device and avoiding oxidation or ash penetration; in theory, a charging seat can support multiple devices.

In fact, there is no commonly used standard in this industry, which brings difficulties to the popularity of wireless charging. The Qi of WPC is the most influential standard at present, and it has more than 200 partners and operators.

But there are also problems with the Qi standard. At present, the technology it supports is actually called "induction charging", and the equipment needs physical contact with the charging seat. And according to the general understanding of "wireless", it should not require physical contact.

Fortunately, the latest version of the 1.2 version of Qi charging technology has increased some new functions, including the real "wireless" charging, and the mobile phone can be charged within 1.77 inches (45 mm) of the charging seat.

The new standard also allows a one - to - one charge to support up to 2000 Watts of high power equipment, such as kitchen utensils. The previous standard can only be one to one.

This new standard provides a lot of new possibilities. If the merchant can install the charging seat in the store, the user can charge the charge nearby, which has a good effect on increasing the stickiness of the user. If the car is equipped with a charging seat, you don't have to charge it in a certain place.

Competitors, Rezence and Power Matters, introduced the "resonant charging" standard before, but WPC said that Qi has more efficient power conversion. At present, the new version is still in the test, and the final conversion rate will reach 70-80%.

In fact, if according to the charging efficiency, the wireless charger is not up to the wire charging. That is to say, it will take more time to use wireless charging. However, the significance of wireless charging is that it can make full use of the scattered time. You don't have to look for a line to plug in the interface. When you don't use a cell phone, put it down to charge it, don't "charge it for a time". The use of this method is very reasonable and rational, as long as you are not on the outside.
