Huawei Mate 20 Pro’s reverse wireless charging will launch on November 27
Chinese technology chief Huawei has officially announced that it will bring only Mate 20 Pro and Mate 20 RS Porsche designs to India from four MET 20-series phones launched last month in London. Launch will be done on 27th November and it will be the first time that a Mt-Series smartphone will be launched in India. It comes with many interesting features and specifications, which includes the company’s Kirin 980 processor and the basic triple camera setup on the basis of the 7 nm process.
A feature of Mate 20 Pro, which is guaranteed to have a smile on your face while showing the apple or Samsung user, is wireless reverse charging.
While Mate 20 Pro can be wireless charged through the Qi charging standard, there is no surprise – the smartphone can also charge other smartphones wirelessly.
It’s easy to do this – just dig in settings and enable options and voices! You can let a friend charge your phone wirelessly.
Although it is interesting, it is important to remember that it is slow. But hey, can you use those extra MAHs for your battery better, right?
If you are wondering how this technology works, then you would like to travel back in your school years and would like to dig into the Physics Reciprocal-Holiday Textbook.
There is a lot with electromagnetic induction in wireless charging – the output of electromotive force in an electro conductor in a changing magnetic field. Although this is textbook definition, let’s be real with it.
You can be remembered as an experiment in which you have transposed a magnetic compass around a copper wire loop in which the galvanometer is connected to its ends. Whenever you move the magnet, the galvanometer needle goes away, which currently indicates the wireless output inside the copper loop.
The changing magnetic field, in this case, is the movement of the magnet, the electric conductor is copper wire and electromotive force (or voltage) is essentially electrical intensity.
Now, the amount of voltage determines how fast the magnet runs, which in turn determines how much flow flows in the loop (because the voltage is directly proportional to the current in the circuit.
Let’s replace this magnet with “Electromagnet” or copper coil with power flowing. Flow flowing through the wire will be in creating a magnetic field (more accurate electromagnetic flux) and so does the same by moving the magnet. Since this copper inspires a current in the loop, it can be called persuasive.
Creating a similarity with the real-life scenario, the charging mat takes the role of motivator (you can also call it a transmitter) while the setup receiver can be called on your smartphone.
This is an overlapping explanation – Wireless charging is more complex in that way because it involves very little miniaturization. From the days of school you will remember that if you make one with ordinary copper wires, then how big an electromagnet can be.
Another issue is to expand this setup on a large set of wireless charging devices – different devices have different voltage requirements. So it is important to establish a universal standard, such that in the socket of all the walls in India, the design of the same kind is low or low.
Here QE charging compliance comes in play, so you will not have to look for a compatible charging pad for your device. There are also other types of universal standards like Airfuel.
Our partner (with the intention of returning) is coming back, the phone not only charges itself with the wireless charger, but also for charging other devices. Most devices only have a receiver part of the setup, which is smaller than the transmitter. The Mat 20 also adjusts the transmitter and this is where the talent lies – which is commendable.
Huawei has not provided a charging how the charging / reverse charging system works so far, but I’m definitely waiting for a teardown video to appear on YouTube.
