When using the facilities, you will often see the prompt that the supporting USB power adapter should be used to charge the battery. Naturally, this is not out of thin air. What you should know is that the charging effect of different types of USB power adapters is different.
Generally, the difference of voltage parameters should not be too 0.5V
When using USB power adapter, the voltage parameters and standard parameters should not exceed 0.5V. For example, a battery is charged with 4V input, that is, it can use 4.5V or 3.5V at most. Once the voltage is not within such a standard range, it may lead to failure to charge at first. Secondly, even if the charging can be carried out normally, it will do some harm to the battery, The fundamental reason is that the battery is also a channel, and if the voltage gathered at both ends is too large, it will destroy the internal structure of the battery.
Generally, the difference of current parameters should not be too 100mA
Generally, the biggest difference between different power adapters is the charging current. I think the current parameters of the charger should not be more than 100mA. The effect of current on the battery is immediate, and the fact that the battery can be charged is also due to the effect of current. Excessive current will lead to deterioration of chemical elements in the battery. In this way, the battery can not be used.
