The era of wireless charging fast

I wonder if you still remember the universal charger in the 80s? Now is already the era of wireless charging fast.

In that era of only 2G, 3G network, everyone is still using the Pepsi, Rockia, now children have never seen the universal charger, should not know that the previous cell phone battery is removable it, the other day brush to a video, about a junior high school students are charging, while playing games and next to the older brother said, why now the electricity is so fast, why not install the battery in the phone, so that Why not install a battery in the phone, so that when the electricity runs out while playing games, there will be electricity again with a new battery. How do I tell him that the 80's and 90's cell phones are battery replaceable?

In fact, I want to ask this child with certainly not a wireless charger, wireless charger is the charger without the traditional charging power cord connected to the terminal device that needs to be charged, using the latest wireless charging technology, through the use of alternating magnetic fields generated between coils, the transmission of electricity, inductive coupling technology will become a bridge between the charging base station and the device.

Wireless charging technology originates from wireless energy transmission technology, which can be divided into two ways: low-power wireless charging and high-power wireless charging. It is based on the principle that through near-field induction, the wireless charging device conducts energy to the charging terminal device, and the terminal device then converts the accepted energy into electrical energy stored in the device's battery. Charging is only need to put the phone on the charging line to charge. Once placed and charged, it is convenient to charge, with high charging power and fast time.

In this fast era, people pursue high speed, high quality development, wireless charging born in response to the times, will also live because of the response to the times, the future of wireless charging may replace the charging cable like the charging cable instead of universal charging.
