Without a charger, your laptop has zero use.
It mostly happens when you forget your charger at home when you are out somewhere.
These are some difficult situations that every laptop user faces.
Does using such a charger create problems?
Does a charger of different wattage and different make harm your gadget?
Is it safe to use a power supply with a different configuration?
These are some questions that every laptop users face and we will attempt to answer them in this article.
What if I use a different make power adapter to charge my laptop?
First and foremost you have to understand how a power adapter works.
The normal DC output is 12 volts but it may differ in varying devices.
Power adapters are a bit like canned food.
Some manufacturers put a lot of information on the label.
Others put just a few details.
And if there is no information on the label, proceed with extreme caution.
The most important details for you to look out are thevoltageand thecurrent.
Voltage is measured in volts (V) and current is measured in amps (A).
(Youve probably also heard aboutresistance(?
), but this doesnt usually show up on power adapters.)
The other important term to know ispolarity.
For direct currents, there is a positive pole (+) and a negative pole (-).
For an adapter to work, the positive plug must mate with a negative receptacle or vice versa.
The next thing to match is the connector.
Remember, using a charger with the wrong voltage rating can potentially damage your laptop.
This is typically because of too high voltage.
But using a charger with too high current wont damage your laptop.
Using a charger with too low current rating might fry the power supply, but not the laptop.
