Laptop plugged in and charging

Are you having trouble with your laptop charger? Are you looking for a different charger to charge your laptop? If you are wondering whether you should use a different charger for your laptop model, we have everything sorted out for you in this article.

Laptops make use of two different types of power adapters to function, that is, DC adapter and AC adapter. Laptop chargers are an external source of power that converts the electric energy into a form that makes your laptop function. 

Each model of the laptop comes with unique and original laptop chargers. However, there are times when they stop working, and you require a replacement. If you are looking for the answers to the questions mentioned above, you have come to the right place. We will discuss whether you can use the different chargers for your laptop in terms of different models.

Can I Use A Different Charger For My Laptop?

The answer to this question is Maybe. The wattage and voltage of a charger should match the desired voltage of your laptop. 

Another essential thing to note is the connector tip that varies from laptop to laptop. If a different charger has a similar connector tip and can provide the desired voltage, it is a possibility that the charger can charge your laptop. However, that is not the case with every other laptop. 

You need to take care of the specifications; otherwise, it can also harm your laptop’s battery.

Power Requirements

All the laptops are created with different power. Some require more power, such as gaming laptops. Therefore, their chargers use high voltage. If you use a different charger that cannot provide the right voltage, you risk damaging your laptop.

In the future, the latest USB Type-C connectors will become the primary source for charging your laptops. As they are interchangeable, you can use them for any other laptop.

Do All HP Laptops Use The Same Charger?

In the case of HP laptops, they all follow a basic standard that means they use 45-230 watt and 18.5 voltage. Even the two-barrel sizes are electrically similar, and they use the “Smart-Pin” feature in almost all the laptop chargers. The third thing is the connector, which is only available in SKUs, though it should be EoL.

The only difference between the chargers is that the new SKUs have a more slender connector, allowing thinner and smaller chassis.

If you intend to use a different HP laptop charger from your HP laptop, look at the wattage: 65 and 45 watts. They are mainly for standard usage, which does not require much power.

Whereas, 90 and 110 watts power the small business class unit, including Elitebook 700 series and Probook, and larger consumer units.

Apart from that, 150-230 watts are made to handle the extra load of the laptop. You can use the chargers with the same voltage interchangeably. In some cases, lower specs are supported by the laptop. However, it will not result in a fast charge as your laptop’s charging circuit directs the charging process. 

Do All DELL Laptops Use The Same Charger?

Dell Laptops require their original laptop charger made with the special power requirements for charging. All the Dell Laptops do not use the same chargers.

However, when the chargers are paired with a compatible laptop model, they are designed to function with all other laptops with the same power output and connection.

Many Dell laptops require only 35 watts to function, where the other laptop requires more than 100w. A dell charger might charge your laptop, though the difference in power output can cause damage.

Voltage And Amp Complication

Even if your laptop and charger’s wattage is similar and the charger can charge your laptop, there is still a risk of laptop damage due to power source differences.

You calculate the wattage by multiplying the voltage and amperage. Any alternative charger amperage and voltage must match the original charger ratings. However, if you order a Dell manufacturer replacement charger, that might not damage your laptop.

Go By Wattage

A specific wattage is designed for all the Dell laptops that ensure their compatibility. Take, for example, if you use compatible chargers with 90W and 75W for your Dell laptop, you might receive a pop-up message of error when you switch the chargers.

On the other hand, you might not receive an error message with chargers from different brands such as Asus, Sony, or Targus with the same wattage and connection.

Do All LENOVO Laptops Use The Same Charger?

The answer is No. All the LENOVO laptops do not use the same chargers. If you search for the 20V, 90W, and 65W adaptors, the chargers are not the same. The series before T6x/Z6x/X6x/R6x used the same 16.5 voltage but included different plugs.

You can find the difference between the adapter design from 20V and 16V adapters. By just looking at their design, you can judge that they are not the same.

However, some Ideapad models have similar connectors, but they use higher power than 20V and cannot be interchanged with Thinkpad adapters. 

16V vs 20V Adapter

If your laptop uses a discrete GPU instead of an Intel GPU, which is shipped with 90 watts and 65 watts adapter, you should use higher wattage of 90 watts or above.

You can conveniently use either a 135w adapters on your laptop that uses either a 90W or 65W adapter. On the other hand, you should not use W510 with 90watts and 65 watts adapter; it will affect the functionality.

If your laptop uses a discrete graphics card and you use 65 watts adapter with it, the laptop will hold itself back from draining more power from lower power adapters.

This may result in slow charging and slow system performance when the laptop is on. Additionally, a higher wattage may cause you to run your laptop at high temperatures.

This year, all the models of Lenovo Thinkpad will use universal chargers based on USB Power Delivery 3.0 specification and a USB-C connector. That does not make you use the same charger for different Thinkpad models, but this power will be compatible with the laptop in the same series.

Do All SURFACE Laptops Use The Same Charger?

In the Surface laptops, the chargers for Surface Pro 6, Surface Laptop 3, and Surface Pro 4 come with the same connector. You can conveniently use either of the chargers on other devices.

In the case of Surface Pro 2 and Surface Pro, you can use the chargers of Surface 2 and Surface RT laptops. Surface 2 and Surface RT provide the output of a 24 Watt power supply, which is sufficient and designed to charge the other two devices. You can also use it the other way round.

The time taken by your laptop to charge with another charger will be different. Your laptop will take a longer time to charge than usual.

USB-C Port

If you own a USB-C charger, they work on all the Surface Laptops without causing any problems. However, you should keep few things in mind before using the USB-C charger with your Surface Laptops:

  • Make sure the USB-C charger you are using can provide equal wattage as required by your Surface Laptop.
  • If there is no power in your Surface laptop and the charger produces 60 watts of power, your Surface Laptop will turn on immediately. On the other hand, if you use a charger with less power, your laptop will not turn on until the battery is 10 percent charged. 
  • If you use a USB-A or low voltage charger, your system will charge slowly, and you might receive an error message stating, “PC is not charging.” 
  • You cannot use both a USB-C charger and Surface Connect Charger for charging your laptop. In that case, your laptop will charge from only the Surface Connect charger.
  • Surface Studio 2 comes with a USB-C port. However, it does not include a battery, which means it cannot receive power from a USB-C charger. You can only use the power chord that is particularly designed to power the Surface Studio 2.

Third-Party Compatibility

It is highly recommended not to use third-party accessories with your devices. They may be incompatible and may result in serious damage to your laptop. You should always use the original Microsoft-licensed accessories only.

Surface laptops can use the chargers from other surface laptops. However, original Surface chargers take care of the health of your Surface laptops.
