PC charger: how to choose?
You are looking for a PC charger to replace the one that is defective. Indeed, buying a PC charger is not a task to be taken lightly, as there are certain standards that must be met. Thus, this article will serve as a buying guide.
Knowing the power and the ideal charger connector
Expressed in watts (W), the power of a charger indicates the maximum energy that the charger can provide. Knowing this value is essential when buying a charger on batshop.com/en. Also, when it is not indicated, it is possible to determine it by proceeding to the following calculation: Charger voltage (V) X Charger amperage (A).
Thus, the ideal charger is the one that delivers a power that can be supported by the PC battery. However, it can happen that the charger delivers a greater power than that supported by the laptop. In this case, it is necessary to make sure that there is not a difference of more or less than one volt between the original value and the replacement value.
Knowing that PC chargers have a voltage that varies between 18.5 and 20V, there is no great concern. Nevertheless, it is recommended to proceed to this verification before any purchase. On the other hand, it is strongly advised against buying a charger with a lower power than the original one. The risk is that the computer will stop working because of a power deficit.

In addition to the power, the charger connector is also an important element to consider. Indeed, the number of charger connectors that exist is impressive, and it is necessary to choose the one that suits your PC. Thus, knowing the size of the connector is essential. This is expressed in millimeters (mm) and represents the inner and outer diameter of the connector.
In addition, it should be noted that more and more manufacturers of laptops make tips that are specific to their brand.
