How To Avoid Buying The Wrong Laptop Power Charger

While they may seem like a simple accessory, there’s more than meets the eye when it comes to ensuring you have the correct charger for your laptop. Unfortunately, not all laptop chargers are created equal, and purchasing the wrong one can lead to frustration and even damage your laptop. With so many options available in the market, it’s easy to fall into the trap of purchasing the wrong charger for your laptop. In this article, we will guide you through essential factors to consider before purchasing and provide invaluable tips on avoiding common mistakes.


Cheap units are red flags.


Cheap units are often red flags when buying laptop power chargers. While the price may be tempting, these cheap units are usually of poor quality and can cause more harm than good to your laptop. 


Avoid universal power chargers.


One of people’s biggest mistakes when purchasing a laptop power charger is opting for a universal charger. While these chargers claim to work with any laptop model, they often have compatibility issues and can even cause damage to your device.

Universal chargers are not explicitly designed for each laptop model, which means they may not provide the correct voltage or amperage required by your device. It can result in undercharging or overcharging, leading to battery problems and reduced performance.

Always opt for a charger designed for your laptop model to avoid this situation. These chargers match your device’s power requirements, ensuring safe and optimal charging.


Another brand’s charger is dangerous.


When buying a laptop power charger, taking a proactive approach is essential. Many people assume that any charger with the proper connection will suffice, but this can be a dangerous assumption. Using another brand’s charger may cause more harm than good, as each laptop manufacturer designs chargers specifically for their devices. These charges are not only compatible in terms of physical connection but also in terms of voltage and wattage.

Using a charger from another brand can result in incorrect voltage being supplied to your laptop, which could lead to overheating or even electrical damage. Additionally, the wattage might need to be increased to power your laptop appropriately or charge the battery efficiently. This can lead to slower computer performance and shorter battery lifespan. Therefore, always opting for chargers designed for your laptop model is crucial to avoid buying the wrong power charger.




In conclusion, purchasing the wrong laptop power charger can be frustrating and costly. By taking the time to research and understand the specific requirements of your laptop, you can avoid these issues altogether. By following these guidelines, you can save valuable time and money in the long run by avoiding buying the wrong laptop power charger. Always check the voltage, amperage specifications, connector size, and type to ensure compatibility with your device.



Frequently Asked Question


How do I make sure I buy the correct laptop charger?


When purchasing a laptop charger, there are a few key factors to consider to ensure you buy the right one. Firstly, check the compatibility of the charger with your laptop model. Look for the specific voltage and amperage requirements mentioned in your laptop’s user manual or on its label. Matching these specifications with the charger you intend to purchase is crucial.

Secondly, consider the connector type. Laptop chargers come with various types of connectors, so make sure the one you choose matches the port on your laptop. You can consult your laptop’s user manual or physically inspect the port to determine the required connector type.

Reading customer reviews and checking for warranty options can also help you make an informed decision when purchasing a laptop charger. Copied!


Can I use a 65-watt charger on a 45-watt laptop?


Yes, you can use a 65-watt charger on a 45-watt laptop. The wattage rating of the charger refers to its maximum output capacity, meaning it can provide up to 65 watts of power if needed. However, it doesn’t mean the laptop will always draw 65 watts. 

Using a higher-wattage charger than your laptop requires is generally safe as long as both the charger and laptop are compatible regarding voltage and connector size. It may be beneficial as the charger will have more power available for other devices or for charging your laptop faster if needed. Ensure the voltage and connector are compatible before using a different charger with your laptop.


What is the minimum watt to charge a laptop?


A laptop’s specific model and power requirements determine the minimum wattage necessary for charging. Generally, most laptops have a charging wattage range of 30-70 watts. However, using the charger that came with your laptop or one that meets or exceeds the manufacturer’s specifications is recommended.


Why are laptop chargers different?


Laptop chargers come in various shapes and sizes, often leaving us wondering why they can’t all be the same. The reason behind this is not just another example of technology companies purposefully complicating our lives. The differences in laptop chargers can be attributed to various factors such as power requirements, connector types, and design limitations.

One of the primary reasons for the variation in laptop chargers is the power requirements of each device. Different laptops have different power needs based on their specifications and processing capabilities. For example, a high-performance gaming laptop requires significantly more power than a lightweight ultrabook. As a result, manufacturers optimize their chargers accordingly to ensure each device receives the necessary electrical current.

Another factor is the connector type used by different laptops. Several connector designs are available in the market, including barrel connectors, USB-C ports, and proprietary connectors specific to certain brands or models. This variation can often lead to frustration when you need to remember your charger or borrow one from someone using a different brand model.


Are replacement laptop chargers safe?


Yes, replacement laptop chargers can be safe if purchased from reputable sources and meet the necessary safety standards. 

To ensure the safety of your laptop and yourself, purchasing replacement chargers from reputable sources or directly from the laptop manufacturer is recommended. It will help minimize any risks associated with using a replacement charger and give you peace of mind knowing that your device is being charged safely.

However, it is always recommended to exercise caution when using any electrical device. It is essential to monitor the charger for any signs of overheating or damage and discontinue use immediately if any issues arise. Regularly inspecting the charger’s cable for fraying or exposed wires can also help prevent potential hazards.


Are broken chargers safe?


Broken chargers can pose a safety risk and should not be used. When a charger is broken, it may have exposed wires or frayed insulation, leading to electrical shocks or fires.

Using a broken charger risks your safety and risks damaging your electronic devices. A faulty charger can deliver an inconsistent or incorrect voltage, which may damage your device’s battery or other components. Chargers in good condition and designed explicitly for your device are always recommended to ensure proper charging and prevent any potential damage.


What voltage is a laptop plug?


In most countries, the standard voltage for laptop plugs is 110-240 volts. This wide range allows laptops to be used in different countries without a voltage converter. 

It is also worth noting that laptops typically come with a power adapter or charger that converts the AC voltage from the wall outlet to a lower DC voltage suitable for charging the laptop’s battery. The output voltage of this charger can vary between 12-20 volts DC, again depending on the specific laptop model.


Can I charge my laptop with an Android charger?


No, you cannot charge your laptop with an Android charger. Laptops typically require a higher voltage and wattage to charge compared to smartphones. Android chargers are designed specifically for charging Android devices with lower power requirements. Attempting to use an Android charger to charge your laptop may result in slow or no charging.
