Many high-speed chargers now claim that their devices can be fully charged within a few minutes. So is this true? This is true, but it should be known that in actual use, we will find that all voltages are virtual electricity. It is precisely because of this that once we have used it for a period of time, we will clearly find the problem, that is, the electromagnetic charging of this charger can not be used for a long time. Obviously this kind of high-speed charger is a lie, and we will now talk about how this seemingly magical device is realized.
The pros and cons of high-current charging
Most of the power adapters we use on the equipment are 5V2A power adapters. The so-called 2A means that it can provide 2A current, but if we make a small amount of improvement on the equipment, this kind of equipment can also provide greater current. And in many cases, this current will not change with the change of the load. Based on such a principle, we can produce a high-current charger, which will excite the internal circuit of our battery when actually working, forming a large amount of current. It is true that part of the power will be stored in the battery, but once the battery continues to work while we are using it, this power will quickly be lost. In fact, this is why we see this charger can complete fast charging.
Similar chargers are harmful to the battery
Although various new energy sources are constantly developing, many of the batteries used in small devices are chemical batteries. This chemical battery relies on the activity of internal chemical elements, and once we let a large amount of current pass Among them, it will cause some of the chemical elements to change, which will directly cause some of the elements in the battery to fail. If a battery is charged in this way for a long time, it will be scrapped.
On the basis of a comprehensive understanding of the power adapter, we can analyze this kind of equipment, and after the analysis, we can understand what the so-called high-speed charger is. It can be seen that this is a big scam. As consumers, we must not be fooled.
