Things To Check Before Buying A Laptop Power Bank
• Your Laptop Power Requirement: Every laptop requires a certain amount of power to run smoothly.
To check your laptop’s power rating; you can use the labeling of your laptop to know.
Here are the ways to know your laptop power consumption :
One of the ways to check your laptop power rating is to take a look at your adapter charger description.
For example, laptops rated at 45watts can be labeled with “45W”.
If you didn’t see 45w at the back of your laptop adapter charger label, check for “Output with V and A”, and multiply the numbers, this will give you the wattage of your laptop.
Example, Output Power : 19V 2.36A, you multiply the numbers, it will give you 45W.
A laptop rated at 90 watts can be labeled with “90W” or 19V 4.73A. This is how you check your laptop power rating using the adapter charger.
Note: If you don’t see 45W, or 65W or any number containing “W”, here is another way to know your laptop’s power rating.
– On your laptop, check the label at the back with “Input (V number) and (A number)”, calculate the numbers with (V and A), this will give you the wattage of your laptop’s power rating.
• Check For The Laptop Power Bank’s Wattage:
A laptop power bank also has its own power ratings, this is usually the battery capacity rating inside the power bank.
Another thing you also need to look out for is the power output of the power bank. Make sure it matches with your laptop’s power rating.
So… In Summary:
Which Laptops Can Be Used on a Laptop Power Bank?
All laptops can be used on a laptop power bank, but this also depends on the type of laptop you’re using and the type of power bank you’re using on the laptop.
