Impact of USB charger quality on battery life

The impact of the quality of the USB charger on the battery is that when you use the device, you will often see the prompt that you must use the matching USB charger to charge the battery. This is of course not a matter of nothing. What you should know is that different types of USB The charging effect of the charger is different. For example, chargers commonly used in mobile phones are now available, and there are many models of such chargers.

So why is it not a problem to use various incompatible chargers in real life? In fact, it is very simple. This is because although the power supply of various chargers is different, there is basically no big difference, and there will not be a 1A. Another situation like 10A. So to a certain extent, they can achieve almost the same effect. But at the same time, you should know that if you use different incompatible chargers, you should carefully observe the difference in electrical energy parameters.

First of all, in terms of voltage, the output voltage of such chargers exists from 4V to 6V, and they can all be used in the charging of specific devices, followed by current, the current provided by mobile phone charging that can be seen on the market now. There are generally three types, the first is 500ma, the second is 700ma and the last is 1A. These chargers are different in power output alone. In fact, the internal design of the charger is different in various details, so in general, various USB chargers are incompatible.

Impact of USB charger quality on battery life

　　 The biggest difference between different chargers is generally the charging current. I think the current parameters of the charger are generally best not to differ by more than 100ma. The current has a direct effect on the battery, and the fact that the battery can be charged is actually due to the current. Excessive current will cause the deterioration of chemical elements inside the battery. In this way, the battery can not be used.

When using a USB charger, the voltage parameters and standard parameters are best not to exceed 0.5V. For example, a battery is charged with 4V input, at most it can use 4.5V or 3.5V. Once used, it is not in such a standard range The internal voltage, first of all, may lead to the failure to charge, and secondly, even if the charging can be carried out normally, it will cause some damage to the battery. The root cause is because the battery is also a kind of path, and if the voltage accumulated at both ends is too large The words will destroy the internal structure of this battery.
