Can I use a 45w adapter on a 65w laptop?

If you’re wondering whether you can use a 45w adapter on a 65w laptop, you’re not alone. Many people are unsure about the compatibility of different power adapters with their laptops. In this article, we will address this question directly and provide a clear answer. So, without further ado, let’s dive into it!

Can I use a 45w adapter on a 65w laptop?

Yes, you can use a 45w adapter on a 65w laptop. Laptops are designed to be compatible with a range of wattages, and using a lower wattage adapter will not damage your laptop. However, there are a few things you should keep in mind.

While a 45w adapter will work, it may not provide enough power to charge your laptop while you’re using it. If you’re running intensive applications or your laptop’s battery is low, the 45w adapter might not be able to supply sufficient power, resulting in a slower charging rate or even draining the battery.

Additionally, using a lower wattage adapter may limit the performance of your laptop. If your laptop requires 65w of power to operate optimally, using a lower wattage adapter may cause it to throttle performance to conserve power. This can result in slower processing speeds and reduced overall performance.

On the other hand, using a higher wattage adapter than necessary is usually not a problem, as laptops are built with safeguards to prevent damage from excessive power. While it’s generally safe, there’s no benefit to using a higher wattage adapter unless your laptop requires it.
