What to Look for When Buying a Universal Laptop Charger


When it comes to laptop accessories, a universal laptop charger is a valuable tool. It provides the convenience of being able to charge multiple devices with a single charger, making it an essential piece of kit for those who frequently use different laptops or travel regularly. However, not all universal laptop chargers are created equal. This article will guide you through what to look for when buying a universal laptop charger, ensuring you make a purchase that is both effective and safe.

Understand Your Laptop’s Power Requirements

Before purchasing a universal laptop charger, it’s essential to understand your laptop’s power requirements. Look for the voltage (V) and current (A) specifications, typically found on the laptop’s original charger or in the user manual. Ensure that the universal charger you choose can provide the required power output to efficiently and safely charge your laptop.


A universal laptop charger’s primary feature is its ability to charge multiple devices. It achieves this through interchangeable charging tips that can be switched to fit different laptop models. When choosing a charger, ensure it comes with a comprehensive set of tips compatible with various laptop brands and models. If your laptop uses a USB-C port for charging, ensure the charger supports USB-C Power Delivery.

Power Output

The power output of the charger, measured in watts (W), is another crucial factor. A charger with a higher power output will be able to charge your laptop faster, but it also needs to match your laptop’s power requirements. Too much power can potentially damage your laptop, while too little power will not charge it effectively. Aim for a charger with a power output similar to your laptop’s original charger.


If you’re often on the go, the size and weight of the universal charger will be a significant factor. Look for a compact and lightweight design that won’t add too much bulk to your laptop bag. Some models may also include features like built-in cable management or foldable plugs for added convenience.

Safety Features

Safety is paramount when it comes to electronic devices. A good universal laptop charger should have built-in safety features to protect both your laptop and the charger. These might include over-voltage protection, over-current protection, and short-circuit protection. Also, look for chargers that meet safety standards and certifications such as UL or CE.


Lastly, consider the warranty offered by the manufacturer. A warranty provides assurance that the company stands behind its product and is willing to provide a replacement or repair if the charger fails due to a manufacturing defect. A longer warranty period typically indicates a higher level of confidence in the product’s quality and durability.


Buying a universal laptop charger is a decision that should be made with careful consideration of your needs and the product’s features. By understanding your laptop’s power requirements, ensuring compatibility, considering power output, prioritizing portability, looking for safety features, and checking the warranty, you can find a charger that provides convenience and peace of mind. Remember, the goal is not just to find a charger that can power your laptop, but one that can do so efficiently, safely, and reliably.
