The Unicom power adapter has a wide range of applications, fine workmanship, over-voltage, over-current standard design, safety and stability, real materials, quality and quantity, so that you can use more confidence.

We may think that the original power adapter is relatively better than the original, but there is not much difference. Usually the input voltage allowed by the load has a safe range, such as the nominal value plus or minus 5%. For example, the input requirement of many 2.5-inch hard disks is 5V plus or minus 5%. The same is true for notebooks. If the input voltage is too large or too small, the protection circuit will be activated and the operation will stop.

However, before the protection circuit operates, the internal voltage regulator circuit has been biased to the upper or lower working limit. In principle, the device life has a certain influence. However, according to the current point of view, the reliability of the electronic component is quite good, as long as it is designed. Within the scope, there will be very few problems, and the life expectancy will not be shorter than the life of the notebook, so this is not the main problem.

The more important problem may be the data security of the notebook, and the sudden automatic protection and stop working is a terrible thing for the computer, especially many friends who do not use the battery. Sometimes the computer's inexplicable restart is also related to this. For the original power supply, the manufacturer knows what kind of load to access, so the nominal voltage and nominal current of the power supply can be easily calculated.

The nominal voltage of the power supply should meet the following two conditions: First, when the high current is output, the nominal voltage minus the voltage drop of the power supply itself should be greater than 95% of the voltage required by the load. Second, when the small current is output, the design voltage minus the voltage drop of the power supply itself should be less than 105% of the voltage required by the load.
