You can use the same adapter for different laptops as long as the wattage and connector tip of the adapter is the same for each computer. Any voltage or amp below or more significant than the laptop requires will prove dangerous to the delicate internal electronics. Laptops need a higher voltage from an outlet, which an AC adapter converts to the appropriate amount. The wattage and connector tip of the adapter must match those of the laptops that the adapter is intended for.


Are Laptop Chargers Interchangeable 2022

Use a laptop charger that converts AC power into high-voltage DC power. You can choose a charger from a variety of choices. A number of them are universal, and others are not. The charger works with all laptop models and brands. It has DC plugs and terminal pins for connecting to your laptop.

Laptops and other electronic devices can be charged using it. Universal chargers come in many different types but they’re not all the same quality. Small and large chargers are available. Some pins are too many while others have too few. Is it possible to interchange laptop chargers? As far as their functions are concerned, all adapters do the same thing – converting high voltages from outside to what your machine needs. The adapters you buy won’t all work with your laptop.

There’s no point in checking whether the adapter provides the ideal amount of volts and amps (anything more or less would pose a danger to your machine). This is because those two factors exclusively determine compatibility with laptop chargers.

What Is Wattage

A laptop’s wattage represents its power requirements. This doesn’t necessarily match up for every computer. Your computer would, perhaps, raise a hue and cry at anything less than 70W as opposed to mine which is fine using even less power than 50W. For a laptop’s battery to charge, it needs a certain amount of volts and amps. It also needs to stay charged.

Simply multiplying your laptop’s volts and amps will give you a good idea of how much power it requires. The device’s sticker should tell you how much energy it needs. You’ll see the voltage (V) and current (A) requirements on the sticker.

Alternatively, you can check your laptop’s user manual if there is no sticker. Anyhow, my computer requires at least 36W of electricity since it operates at 12V and 3A. A power adapter with a lower output cannot be used.

How to Use One Charger for Multiple Laptops

There is no need to deal with a universal charger with adapter connector tips, etc. You will need a universal charger to charge multiple laptops using the same charger. There is one cord in a universal charger but a variety of barrel plugs. The advantage of this is that you can charge multiple laptops with just one power cable (one charger). When setting up a computer, you apply the proper connector tip.

Check out your laptop’s power (input) requirements before you leave. Yeah, make sure you do that. You can now apply the formula to each machine and calculate its wattage. Find out what laptop requires the most significant amount of power. The only thing you have to do is find an adapter with a higher wattage than the laptop that consumes the most energy. If it can charge that one, it should set all the laptops on your desk.

We have one more thought to consider. There are dozens of connector tips available for universal chargers, but you’ll still end up hitting disfavor if you don’t choose one that has a wide range. The connector tip may not fit every system. It usually occurs with older laptops and systems. A universal charger won’t disappoint you if your laptop collection does not include anything from your father’s or grandfather’s time.

Power Requirements

If you’re planning on sharing an adapter for multiple laptops, make sure the adapter supports the wattage range necessary to power the laptops. To select the correct adapter, you should look at the laptop’s underside for the voltage and amp requirements.

The wattage of your adapter will be determined by multiplying these two numbers together. An adapter capable of providing a wattage rating of at least 60W would be needed for a laptop requiring 19V and 3.16A. Adapters lower than the minimum wattage requirement cannot be used, even if they come with a higher wattage, such as one with 70W or 90W.

Connector Tip

The wattage of an adapter is only one factor to consider when choosing one to share between laptops. The adapter’s wattage is meaningless if the tip does not fit your machine. Laptop adapter jacks come in various shapes and sizes, from small round ports to large oval ones.

The same laptop may have different adapter connections. It can cause damage to both the adapter jack and the cord connector if you force an adapter connector into an adapter port, despite its size and shape.

Universal Chargers

If you determine that your laptop requires a minimum wattage, then shopping for a universal adapter is best to minimize issues with different connector tips. It is possible to use a universal charger to charge multiple laptops by changing the connector tip, so you only need one cord to charge various laptops.

Most universal adapters will come with various prizes, though not all are compatible with every adapter type, especially for older laptops with larger connectors.


The adapter may not work because of a software conflict or a defective adapter, even if it is supposed to. Verify first that the adapter provides the right amount of energy with a voltmeter. In the case of a laptop with a battery, you might want to test the adapter on the computer without a battery since sometimes the battery prevents the computer from recognizing the adapter.

It may be necessary to upgrade the operating system and the BIOS to take advantage of the new hardware. An adapter jack that is broken or loose may be to blame for a weak connection.

How Do You Know Which Laptop Charger Is Compatible

It is not difficult or difficult at all to determine which laptop charger is compatible with your device. You have to do a little research. You can easily find information about which laptop chargers work with your computer on your laptop or the charger. A laptop charger must be compatible with the computer you are choosing before you choose an electronics store.

The laptop charger packaging should include all this information. You can use that specific laptop charger for your laptop if it appears on the list. You should look for another laptop charger if it does not appear on the list.

You can also check the bottom of your laptop to see if the charger you have is compatible with it. Manufacturers stamp specifications onto laptop parts to help you find the right laptop replacement parts. There are many kinds of stamps, so look for one that says “AC adapter” or something similar. You can choose a charger by its model number, which indicates if it is compatible with your laptop.

The specs for the computer and the charger should match for you to determine whether or not a charger is compatible with your computer. Make sure the input and output voltages match. In addition, the charger must be compatible with your laptop’s connections.

What Can Happen If You Charge a Laptop With the Wrong Charger

The charger must be correct when it fits perfectly into the laptop’s charging port and has the correct polarity. How can it be wrong? You might be using the incorrect charger if it has an incorrect voltage, incorrect current, incorrect polarity, or incorrect amperage. There will be a problem if the voltage is not correct. You could ruin your laptop by exposing it to high voltage. The computer can’t run properly at low voltage.

When using a high-current charger, your laptop will not be affected. In contrast, the power supply of your computer will be damaged. But your computer remains unaffected. A laptop charger with a higher wattage will not cause any problems. The charger will draw only as much power as the computer requires. The charger will overheat if the wattage is too low. This may damage your computer.
