Nowadays, we have more and more chargers at home, which we can use for our phone. But, nevertheless, not all of them offer us the fast charging technology that supports the mobile we have. Some can even load much slower than others, which is not ideal.
In order to recognize those that are designed to take advantage of this technology in the smartphone, we will have to put this accessory to the test before using it daily. However, it is not something easy to understand, although we will try to explain it so that anyone can look at that power connector they have at home and know if they are going to offer a slow or fast speed.
identify it
In addition, there is no single method with which to recognize a fast-charging accessory, we have a series of options at our disposal that give us this information. Any of these methods is equally valid, we will only have to decide on the one that is easiest for us.
for the inscriptions
The first of the options we have to find out whether to enjoy this technology will be by looking at the design of this device. In all cases, those that have the fast charging function could specify it in their design, either with a name based on the types of this functionality in mobile phones or with some standard technology, as is the case with the QuickCharge.
This is not being said without complications that we find an adapter that offers a higher voltage than usual and with it we could get our mobile to charge faster. However, this does not allow us to know another important point such as power, something that we will see later how we can calculate it.
Android tends to ‘snitch’
In the case of the iPhone, this will not ‘tell’ us at any time. On the other hand, in the Android operating system, it could tell us if it is working or not. When the phone is connected to power, we might see a message on the lock screen, which may say ‘Charging’, ‘Charging fast’ or even ‘Charging slowly’.
The first message reveals that our smartphone is receiving energy at a standard power, while the second will tell us that we do have a higher speed so that the terminal fills its battery ahead of time.
voltage is the key
In the event that it does not carry any inscription beyond that of the specifications that are mandatory, we will have to look at the section where it says OUTPUT. In case the numbers that appear are 5V: 2A, we are facing a charger that does not enjoy quality and is standard. Therefore, the mobile will fill its battery at the minimum power.
But if it is also accompanied by other power options such as 9V:2A or, for example, 10V:4A, it does enjoy a higher speed. This is the most relevant information of these accessories and which we should always take into account when lending us someone, an adapter or not using the one that comes standard with the mobile phone.
By loading animation
This will depend on the brand of your device, since it is not something that is included as standard in Apple phones or those that have Android. That is, many manufacturers differentiate the animation that appears when we connect the smartphone to the current, that is, when the fast or standard technology is working. As is the case with Xiaomi, OPPO, Realme and others. Therefore, when the mobile uses this functionality, we will see that the animation or the icon will indicate it to us .
use an app
In case you still didn’t know, there are different specific applications that have been developed to tell us in detail what happens on our mobiles when we connect them to the current.
In this way, it will be easier to see the charging speed in real time , as well as the time remaining for the terminal to fill up completely. One of the best known is AccuBattery , the problem is that it is only available on Google Play. But, for those who have Android, they will be able to enjoy a software that will show a bar that will turn green when this technology is working. In addition, we can see the amperage and the total capacity of the battery.
How powerful can they be?
When mobile phones are presented or even when we go to buy them, we find that manufacturers talk about the power with which their batteries can be filled, which is represented in charging watts . However, when we look at the accessory, we do not see this data anywhere. And that can make us be somewhat confused with what the brand of our phone is telling us.
To find out, it is only necessary to carry out a simple mathematical formula, in which we are going to multiply volts by amps and we will have as a result the power that a charger offers us. This will help us to know if it is going to offer us the maximum power that the mobile supports. Information that is written on the side of the charger, for which it is sometimes necessary to get very close or even put on our glasses. For you to understand it a little better, for example, it would be as follows:
- 5V:2A = 5×2 = 10W.
- 9V:2A = 9×2 = 18W.
- 10V:4A = 10×4 = 40W.
Although, over time these accessories have advanced so much that we can already find some with large amounts of watts. For example, OPPO and Xiaomi have managed to offer us 120W, which allows us to fill a 4,500 mAh cell in just 15 minutes. This has caused the charger to become as important as the terminal itself.
Not everyone will serve you
However, that a smartphone has a higher power and according to our terminal, does not guarantee that it will work. Some specific brands and models have identification systems that only allow you to make the most of it on devices where they have been tested.
For example, we will not be able to use the fast charge of a Huawei mobile in a Realme that does not accept as much power as they have not been developed by the same manufacturer. However, if you use one with fewer watts for your phone, don’t worry, because by using other incompatible adapters we will only make the power fill 100% more slowly.
On the other hand, if we opt for one that has more power, calm down because we would not put the smartphone and the useful life of its battery at risk either. And all thanks to the technology of telephones, which manage to ‘cap’ this extra power so that it is not dangerous for the terminal and lasts a long time without damaging it. Although, we will always recommend that you make sure that it is fully compatible, so we will not have any doubts about whether it will work correctly or not.
Original or fake?
There are many users who save a few euros when changing this accessory to charge the mobile . However, in these cases, the cheap could be much more expensive. More than anything, because when we have a problem with the battery, on many occasions it will be this accessory.
And, it will be much more so when it is false. In addition, the main thing about those accessories that are not original is that they could ‘scam’ us in terms of the power or compatibility they offer for our mobiles. Therefore, the best option when buying a new one will always be to opt for the one made by the brand of your phone. Thus, you will avoid possible problems such as not filling the energy of your terminal 100% or being slower than what was promised.
The stock charger is not always the best
We tend to think that the ideal charger for our phone and also the fastest is the one that comes even in the box that we have compared, although this is not always the case. Many manufacturers choose to add a lower speed charger than the phone can enjoy. This forces us to make an extra outlay if we want to get the adapter with the highest charge, so as not to have to wait so long for it to recharge.
To be able to find out what the speed supported by the terminal is and find the charger that gets the best performance, we recommend that you go directly to check the technical data sheet on our site of your smartphone, in order to know exactly how much the mobile you have supports. Another measure is to visit the manufacturer’s website, where the load speed it supports is specified.
The next thing will be to look at the charging power offered by the integrated charger, as we have previously mentioned. In case it does not correspond, we have to locate a charger in the manufacturer’s own store that manages the speed that the phone can support or something higher . The mobile will be in charge of limiting it, to achieve the best result and that we take advantage of it.
Problems of being wrong
However, we must also take into account that it will be useless to connect our smartphone to a 30W one, if it does not have fast technology and is not even compatible with this power . More than anything, because if we connect it and it is only capable of receiving 20W, it will continue charging at the same power.
For this reason, in the event that we sometimes use a charger that is capable of offering more energy to the terminal, our device and, more specifically, its processor, will detect that it is not something that it can resist and will ‘cap’ it in such a way that we don’t have to worry about whether or not it damages the terminal.
This is thanks to the technology of the last, since it has made it possible for this to lose importance, since we can use chargers, even if the voltage does not match, even without it becoming dangerous . And if we use one with less power than our phone can withstand, we can still be calm, because it will not affect either of them. The problem will be that we will notice that the terminal will take much longer to fill its battery to 100%.
