Laptops are powered by a charger. If yours is damaged or has trouble charging your laptop properly, you should change it. However, there are some things to consider when choosing the right charger for your laptop. In this article you will find all the information you need to choose a good charger without any risk.
Which connector is right for your laptop?
There are many different laptop chargers on the high-tech market. Therefore, each laptop has its own type of connector. For example, a Sony laptop would use a charger with a adapter for laptop sony. When choosing your charger, check if the connector is compatible with your laptop. Ideally, you should keep your old charger. Then you can simply compare the connectors of the new and old charger. If you don't have the original charger, simply find the model number of your laptop. Look up the model number on the internet to find the connector type of your charger.
What is the correct current and voltage?
All types of chargers have two types of voltage, each expressed in volts: the input voltage and the output voltage. The input voltage is the voltage that is transferred from the wall socket to the charger. Choose a charger with an input voltage of between 100 and 240 volts. The output voltage is the voltage that is transferred from the charger to the laptop.
It should not be too high or too low, as this could damage the laptop. In addition to the voltage, there is also the current in amperes. The amperage, i.e. the amount of energy in the replacement charger, should be greater than or equal to that of the original charger. If you use a charger that provides little power, your laptop will not work.
How powerful is your charger?
You will often see the power rating listed behind the replacement charger. This is not always the case with original chargers. The wattage value of the replacement charger may exceed or equal that of the original charger. With a lower charging power, your laptop will not work. It is easy to calculate the wattage of your charger in watts. Simply multiply the voltage in volts by the current in amps.
