Laptops are really necessary for our daily life, it requires energy to function, which will be provided by the charger. This is an important device for supply the electrical current in our appliances so you should always know how to choose between universal chargers, if you need it.
It may happen that when using different chargers failures occur or that our laptop is damaged, for these reasons it is necessary to ask what happens if I connect a higher voltage charger to my laptop? Are universal chargers good?
It is very important to know what type of charger we can feed our device with and if the one we have is suitable for it. For this we will be contributing all the necessary information about universal chargers, ensuring that your computer does not suffer any type of damage.
Factors to have before charging a laptop with a universal charger
Before connecting your laptop to a universal charger, it is important that you take into consideration certain factors that can save you headaches. Let’s start with what the power required by the laptop will be the one indicated by its original charger, having to take it as a reference. If you don’t have the original charger where you can see the nameplate, you can find out how much voltage and amperage your laptop requires to select between universal chargers.
To know the minimum power that the universal charger you want to use must have, you will have to multiply the voltage (V) required by the current (A) consumed. The result will be the base power your laptop consumes, considering that if it is powered by a lower power universal charger, it can result in a general malfunction.
On the other hand, there are universal chargers that are a base power greater than that of your laptop that can work optimally as long as they have the correct voltage.
How are universal chargers used to charge a Laptop?
Universal chargers work like any other laptop charger, except that can have different connection tips as well as with a voltage regulator. In general, its power is usually 90 W because it is a commercial value capable of covering all the powers of the models of the most recognized brands.
Once the correct connector is placed on the laptop, the knob is adjusted to the required voltage and the plug of the laptop is connected to the outlet. They are basically used as a normal charger. There are also universal charger models that automatically detect the voltage level to place the knob there.
Problems when using universal chargers to charge laptops
One of the drawbacks that can occur when using a universal charger to charge your laptop is when its power is lower. Although you can charge a laptop with a lower power charger, due to the lack of it a fault is more likely due to high power consumption, exceeding the nominal levels of the charger.
This can cause overheating, and damage both the charger and the laptop by shorting out. Likewise, another problem is the short lifespan these universal chargers can have due to the fact that it has moving parts that are more easily damaged.
In the same way, a high-powered universal charger is often heavy and oversized, so it can be a hassle. In addition, charging a laptop with a lower power universal charger can even detract from its performance.
What happens if I use a higher voltage charger on my laptop?
Mainly the voltage is all that physical magnitude that allows us to measure the different electrical potentials present between two points. Many devices are manufactured to withstand varying degrees of voltage, which is why manufacturers they add information on the laptop and in the charger. This indicates the appropriate voltage to charge the equipment, providing an increase in battery life, to use your laptop for longer.

The voltage is very important because it corresponds to the force with which the electrons leave the charger. If the voltage is too high it causes a short circuit, because it will produce an overload for a long time which can overheat the cable conductor, until the insulation melts.
Equally if the voltage difference is noticeable, the laptop could burn, and if the source has less amperage than what the equipment consumes, it will endanger the source. Likewise, if a charger with less voltage than necessary is used, it will not work.
So if you use a charger with a high volt level that the laptop does not tolerate, this will be damaged. But if the charger has a high power level but the voltage levels are the same, then there will be no danger of damage.
For these reasons, it is necessary that check the charger voltage before connecting it to your computer. It can also happen that you connect a charger and your laptop does not charge, this problem will not be mainly the fault of the voltage, you will have to see different factors to repair this fault.
Are universal chargers good for my laptop?
It is very common that the chargers that our laptop comes with are damaged or lost and for this reason you have to choose another. Generally, the most accessible and easy-to-find chargers are universal chargers.
It should be mentioned, that yes you can use a universal charger, but you have to be clear about different factors. The first is to verify the type of connector, because not all are the same, there are cylindrical, closing and locking and molex.
Check that this can connect to the laptop properly. If at any time you want to use one of these chargers and avoid any risk, you can buy a universal adapter, this will be very helpful when charging.
You have to pay attention on the quality, as these can be very cheap and for that reason a lot can be bad. The adapters that these have may not have been made in the best way, making them not last as long as a good charger would. Likewise, if the device is very poorly made, it can cause problems for your equipment.
This can lead to a voltage that is not adequate is producedTherefore, the best thing you can do is look for those that have the verification of insured laboratories and with a long guarantee period.
Other factors to consider before using a universal charger
A primary factor is to review the characteristics or specifications of your laptop, this is done to know the exact voltage your computer needs to receiveBecause if you use the wrong one it can cause a great risk.
By knowing the correct voltage, you will be able to know what type of charger to use. Always try to make sure that the charger is in good condition, try to keep the cable properly connected to the power adapter.

If this is not in good condition it is best to eliminate its use. Also check the ferrite core, because it is usually the part of the charger that is most often damaged.
