In this article we are going to see how exactly fast-charging chargers work and whether or not they are advisable for mobile and other compatible devices.
It is increasingly common to read among the features of new smartphones and electronic devices that have “fast charging.” To find this feature you do not have to go to flagships or high-end mobile.
Currently, even mid-range phones include it. But what is fast charging? How do they work so that the battery charges so fast?
There are chargers that allow you to recharge 50% battery in 10 minutes. In fact there are those that charge the mobile 100% in just 20 minutes. With a normal charger, the average time to 100% charge a battery is approximately one hour.
Are fast-charge chargers good?
The batteries of the mobiles do not last what we would like and sometimes, we have to charge them several times a day, therefore, these chargers are quite practical. They can get us out of a hurry quickly when we don’t have a battery and we have to leave home fast.
How do fast charge chargers work?
To explain how fast-charge chargers work, we will first explain how normal chargers work. The batteries basically contain 2 chemicals.
When they join together, they react and transform into only 1 chemicals. A flow of electrons takes place, which is what generates the energy so that the mobile components can work. Basically, that flow of electrons is what we call electricity.
When we charge the battery of a mobile, the reverse procedure takes place, that is, electrons are “plugged in” and a change, the chemical compounds react, but vice versa, that is, they return to their original state. They are ready to start the initial procedure again.
They come together again and when creating electrons that feed the circuit, the functions of the different electrical elements of the mobile phone begin.
The fast-charging charger works on that principle, but more power is delivered than in a conventional charger. Basically, all fast charging chargers are governed by the same principle, but there are different types. In some models, we send more voltage and amperage and that is specifically the key.
In a conventional charger 5 volts and 2.1 amps are delivered and in a fast charging 9 or even 12 volts are supplied. In the case of amps, you can reach up to 3.
We define volts and amps as physical quantities that are used to measure the passage of currents (electrons). Volts are the electric potential and amps can be defined as “the amount of electrons that are supplied.”
For example, many of the fast-charging chargers supply 11 volts and 5 amps, so they can charge 3,000 mAh in just 20 minutes, something incredible.
Actually the amperage is not as important as the voltage, although it must always reach 2 A. Although the charger has a lot of amperage, the mobile will only consume what it needs; if there is less quantity, instead, the device charges more slowly, but this is not bad at all. In fact, the slower the better charge is for the health of the smartphone.
So is fast loading bad?
Yes in the long term. The faster the phone’s battery charges, but it is for the battery for these reasons:
1. Chemical reactions occur very quickly, which causes the components to eventually crystallize over time.
2. When delivering so much voltage, the temperature that reaches the battery is very high, and we know that one of the great enemies of the batteries is the excess heat.
Electric cars also have fast charging, they are the well-known superchargers.
Many people usually, but it is not advised by what we have said before. Its use should be limited only in situations where there is hurry.
In cars, they should only lose when long distances are recorded, since fast charging is even more damaging in cars. If we charge the car with fast charging regularly, we will notice that it loses autonomy day by day.
Therefore, fast charging is very useful in case of emergency but we should not abuse it on a daily basis as it will damage the battery of the device in the long term.
Therefore, many manufacturers decrease the speed of the battery charge when it reaches higher levels. For example, some brands disable fast charging when the device reaches 30% and others do so at 40%; from that percentage, the power is reduced and it starts charging normally.
