Have you ever lost your laptop charger and needed a new one but don’t know what type of charger rating you should buy?
When looking for a replacement for your laptop charger, you might see 45W and 65W chargers, but which one does your laptop need?
Alright… Let’s find out!
What Does This Sign “W” or “Watt” Mean?
(W) or Watt are the same, it is the amount of power a charger can give to your laptop. Let’s take an example using an analogy of a filling a water to a bottle.
– A 45W charger is like a small tap, it fills the bottle slowly.
– A 65W charger is like a bigger tap, it fills the bottle faster.
The higher the wattage of the charger, the faster your laptop will charge (if your laptop supports it).
How to Know If Your Laptop Needs 45W or 65W
Here are the 3 ways you can check your laptop’s wattage or power rating:
1. Look at your old charger – If your original charger says 45W, then use a 45W charger. If it says 65W, then use a 65W charger.
If you have lost your charger, then check no 2.
2. Check the bottom of your laptop – Some laptops have a sticker that tells you the laptop’s wattage.
You should note that if your laptop is rated for 45watts, the recommended charger you should get is 45watts charger. And if 65watts, the recommended charger is 65watts too.
3. Search online – If you’re not sure, search engine like Google with your laptop model, you will find the answer to your question or you can visit your laptop’s manufacturer website.
You can search on Google using this example: “Hp (your laptop model number) wattage”.
What Happens If You Use the Wrong Charger?
– Using a 45W charger on a 65W laptop – Nothing bad will happen to your laptop basically, just that your laptop might charge slowly or not charge at all when you’re using it.
– Using a 65W charger on a 45W laptop – Again, in this case nothing serious will happen because most laptops only take the power they need and ignore the rest. Your laptop will just charge normally without any problems.
To Sum it up:
To keep your laptop working safely and properly, always use the right charger despite it can accept higher watts charger or lower watts charger for your laptop.
If your laptop needs 45W, use a 45W charger. If it needs 65W, a 65W charger is recommended.
But if you’re in doubt, a 65W charger is usually a safer choice because it can work for both, hope this helps.
