The laptop is being made very professionally over time. It is being made smaller and slimmer to enhance its beauty. Its internal supply will also be smaller, so we see laptops with different supplies. But can we use 65w charger for 90w laptop? Can it be used safely?

Using the wrong charger can also damage your laptop, but in today’s advanced age, you can charge your laptop using a power supply more extensive than the required power. We will explore how it is possible to use a lower-wattage charger for your high-performance laptop without compromising its functionality or longevity.

Can we use 65w Charger for 90w Laptop?

We rely heavily on our laptops to keep us connected and productive. With the increasing demand for high-performance laptops, power requirements have also increased significantly. This has led to manufacturers providing higher-wattage chargers for their devices. An underpowered charger may result in slower charging times or even prevent the laptop from charging altogether.

While using an overpowered charger may not cause harm to your device, it could shorten your battery life expectancy. One way to determine if your charger is underpowered is by checking whether the voltage output matches your laptop’s requirements.
You risk damaging your laptop and the charging cable if it doesn’t fit.

Replace the Original Charger:

If you face any issues, it’s best to immediately replace your original laptop charger. Using a damaged or faulty charger can cause severe damage to both your laptop and the battery within it. Using an improper charger can lead to slower charging times and poor battery life in the long run. When choosing a replacement charger, ensure it is compatible with your laptop model.
Look for chargers with reputable brands and good user reviews.

A Laptop Charger Affects Performance:

Using a charger that doesn’t match your laptop’s specifications can cause damage to its battery and motherboard. This damage can cause your device to run slower or even crash. A factor that affects performance is the quality of the charger itself. Cheap chargers often need the safety features and voltage regulation systems found in original chargers. Using low-quality devices puts your system at risk.

Investing in a genuine charger that matches your laptop’s specifications for optimal performance and longevity is essential. A good charger will ensure your battery lasts longer while delivering consistent power output to maintain high speed and efficiency.

Use a 65w Charger in Place of a 90w Charger:

Using a higher-wattage charger than the one recommended by the manufacturer can cause some people to think it is better for their device. Using a 65w charger instead of a 90w charger may be better than it seems, and there are likely situations when this could be a good idea. Most modern laptops are designed to work well with chargers that have different wattages than their original ones.

If you have a 90w charger for your laptop but find it too heavy or bulky to carry around at you all the time, switching to a 65w charger could be a good solution. Not only will this shorten the weight of your bag, but it could also save you money since lower-wattage chargers are often less expensive.
Remember that using a lower-wattage charger may result in slower charging times or reduced performance if you run demanding applications.

What Happens if I use a 90W Charger Instead of 65W? 

Using a charger with a much greater wattage than the one that is relocated with your device might seem like an easy solution to charging your device faster, but it could cause problems in the long run. Although using a 90W charger instead of a 65W charger may not cause immediate harm to your device, you should be aware of its risks.

Using a higher-wattage charger can lead to overheating and potential damage to your device’s battery. The battery is designed to accept only a certain amount of power at once, and exceeding this limit can heat the battery cells and reduce its lifespan. If there are any faults in your device’s wiring or circuitry, using an incompatible charger could exacerbate those issues.
An issue with using an overpowered charger is that it may overload other components in your device.

Does a Higher-Watt Charger Damage the Battery?

Many believe using a higher-watt charger to charge their smartphone or laptop can damage it. That is not entirely true. Most modern devices are designed to handle different charging speeds and wattages without causing harm to the battery.

The wattage of a charger determines the speed at which it charges your device. A higher-watt charger will charge your device faster than a lower-watt one. This does not mean that it will damage your battery. Most modern batteries are equipped with intelligent charging systems that regulate the amount of power they receive and prevent overcharging or overheating.

Some manufacturers have designed their devices to support fast charging using high-watt chargers. Apple’s latest iPhones come with fast-charging capabilities that allow them to charge up to 50% in just 30 minutes using a 20W charger.

Final Words:

Not all laptops require the same amount of power to charge. Some laptops come with 65W chargers, while others demand a higher wattage charger of around 90W. Can we use 65w charger for 90w laptop? While it is possible to use a 65w charger for a 90w laptop, it is not recommended. The charger may not provide enough power to the laptop, leading to slower performance and potential damage over time. Sticking with the manufacturer-recommended charger is best to ensure your laptop operates at its full potential and doesn’t risk any damage. If you need more clarification:

  • Consult the manufacturer’s specifications or speak with a professional.
  • Don’t compromise on the health of your device for convenience.
  • Choose the right charger and keep your laptop running smoothly for years.


Do higher watts mean faster charging?

It depends on the related charger and battery being used. Higher-wattage chargers are more powerful and can charge a battery faster.

What happens if I use a lower-wattage laptop charger?

If you are using a lower-wattage laptop charger, it may not be able to supply sufficient power to your laptop. It could result in your laptop not charging or being less powerful. You should upgrade your charger if this is the case.

How do I know if my laptop is compatible with a 65w charger?

Ensure your laptop has a USB-C port, and your laptop’s battery is at least 50% charged. Check the power cord from your laptop to ensure it is compatible with a 65w charger. Also, check the charger’s voltage rating to ensure it is compatible with your laptop.
