How to Choose the Right Laptop Charger

Share the Post:

Choosing the right laptop charger is important because not all chargers are the same. Even if the charging tip fits into your laptop, the charger may still have the wrong voltage, wattage or connector type. Using the wrong charger can cause slow charging, charging warnings, overheating, or no charging at all.

If your laptop charger is lost, broken, damaged or no longer working properly, the safest option is to replace it with the correct charger for your laptop model.

Check Your Laptop Brand and Model Number

The first thing to check is your laptop brand and model number. This helps narrow down which charger your laptop needs.

For example, you may need a charger for a:

HP Pavilion
Dell Inspiron
Lenovo ThinkPad
Acer Aspire
Asus VivoBook
Toshiba Satellite
Samsung notebook

Instead of searching only for “laptop charger”, it is better to search using the full laptop model. For example, “Dell Inspiron 3501 charger” or “HP Pavilion 15 charger” will give better results than a general search.

Check the Old Charger Label

If you still have the old charger, check the label on the power adapter. It usually shows the voltage, amperage and wattage.

You may see details like:

19V
19.5V
20V
3.33A
4.62A
45W
65W
90W
120W

These numbers matter. A charger with the wrong output may not work properly with your laptop. If the wattage is too low, the laptop may charge slowly, lose power while in use, or show a warning message.

Check the Charger Tip

Laptop chargers can have different connector tips. Some laptops use round-pin chargers, some use slim rectangular tips, and many newer laptops use USB-C charging.

Before ordering a replacement charger, check:

The shape of the connector
The size of the tip
Whether there is a centre pin
Whether the laptop uses USB-C
Whether the charger fits firmly into the charging port

A charger can have the correct wattage but still not fit if the connector is wrong.

Make Sure the Wattage Is Correct

The wattage tells you how much power the charger can supply. Common laptop charger sizes include 45W, 65W, 90W, 120W, 135W and 180W.

Smaller laptops often use 45W or 65W chargers. Larger business laptops, workstations and gaming laptops may need higher wattage chargers.

If your laptop needs a 90W charger and you use a 45W charger, it may charge slowly or not charge at all while the laptop is in use. This is why it is important to check the correct wattage before buying.

USB-C Laptop Chargers

Many modern laptops use USB-C charging, but not every USB-C charger is suitable for every laptop. Some USB-C chargers are made for phones or tablets and may not provide enough power for a laptop.

If your laptop charges with USB-C, check the required wattage. A laptop may need a 45W, 65W, 90W or higher USB-C charger depending on the model.

You should also make sure the USB-C cable can handle the correct power output.

Signs You Need a New Laptop Charger

You may need to replace your laptop charger if:

The laptop is not charging
The charger only works at a certain angle
The cable is damaged
The charger overheats
The charger makes a buzzing sound
The charging light does not come on
The laptop charges slowly
The charger is missing or lost

If the charger is damaged, it is better to replace it rather than keep using it.
