Can a phone charger charge a laptop? The short answer is no. While it may seem convenient to use your phone charger to power up your laptop, unfortunately, it won’t work. The reason lies in the power output of the charger. Phone chargers typically provide a lower voltage and wattage than what a laptop requires to function properly. So, if you’re searching for a quick fix to charge your laptop, using a phone charger isn’t the solution you’re looking for. But worry not, as we delve deeper into the topic, we’ll explore alternative options that will meet your laptop charging needs. So, let’s get started!
Can a Phone Charger Charge a Laptop?
Have you ever found yourself in a pinch, with a dying laptop battery and no charger in sight? In these moments of desperation, you may have wondered if it’s possible to use your phone charger to power up your laptop. After all, they both have USB ports, so it seems like a logical solution. But can a phone charger really charge a laptop? Let’s dive into the details and find out.
The Difference between Phone Chargers and Laptop Chargers
To understand whether a phone charger can charge a laptop, it’s important to recognize the differences between the two types of chargers. Here are a few key distinctions:
1. Voltage: Phone chargers typically provide a lower voltage output, usually 5 volts, while laptop chargers deliver a higher voltage output, usually ranging from 16 to 20 volts.
2. Amperage: Phone chargers usually have a lower amperage output, typically around 1 amp, whereas laptop chargers have a higher amperage output, ranging from 2 to 6 amps.
3. Power Delivery: Laptop chargers are designed to provide a higher wattage to meet the power demands of a laptop, while phone chargers are optimized for charging smaller devices like smartphones and tablets.
4. Connector: Laptop chargers come with a specific connector that is designed to fit into the laptop’s power port, while phone chargers have a different connector that fits into the phone’s charging port.
Given these differences, it’s clear that phone chargers and laptop chargers are not interchangeable. However, there are some situations where a phone charger may be able to provide a limited charge to a laptop.
Can You Charge a Laptop with a Phone Charger?
In most cases, using a phone charger to charge a laptop is not recommended. Here’s why:
1. Incompatible Voltage and Amperage: As mentioned earlier, phone chargers provide a lower voltage and amperage output compared to laptop chargers. Using a phone charger with a laptop could result in insufficient power supply, leading to slow charging or even damage to the laptop’s battery, charging circuitry, or other internal components.
2. Underpowered Charger: Even if a phone charger is able to fit into a laptop’s power port, it may not have enough power to charge the laptop while it’s in use. Laptops typically require more power than phones, especially when performing resource-intensive tasks like gaming or video editing. Using a phone charger in such cases may not provide enough power to keep the laptop running or charge it at a reasonable rate.
However, there are a few exceptions and workarounds that may allow you to charge your laptop with a phone charger in certain situations.
Exceptions and Workarounds
While it’s generally not recommended to use a phone charger to charge a laptop, there are a few scenarios where it might be possible:
1. Low Power Mode: If your laptop has a low power mode or battery-saving feature, enabling it can help reduce the power consumption, allowing a phone charger to provide a small charge. However, this will only extend the battery life slightly and is not a long-term solution.
2. USB-C Power Delivery: Some newer laptops, particularly those with USB-C ports, may support USB Power Delivery (USB-PD) technology. USB-PD enables higher power delivery, allowing the laptop to charge using a compatible USB-C charger. In this case, you can use a USB-C phone charger that supports the appropriate power delivery standard to charge your laptop.
3. USB Power Banks: Portable USB power banks designed for charging smartphones and tablets often have higher power outputs. In some cases, these power banks may have enough wattage and amperage to charge a laptop. However, not all power banks are capable of providing enough power, so it’s crucial to check the specifications and ensure compatibility before attempting to charge your laptop.
4. USB to Laptop Charging Cables: There are USB to laptop charging cables available on the market that claim to allow you to charge your laptop using a USB charger. These cables often have a step-up converter built-in to boost the voltage and amperage to match the laptop’s requirements. However, it’s essential to research and choose a reliable and compatible cable to avoid potential damage.
The Risks of Using a Phone Charger to Charge a Laptop
While there might be some cases where you can use a phone charger with your laptop, it’s important to be aware of the potential risks involved:
1. Damage to Laptop Components: Using a phone charger that doesn’t provide the appropriate voltage or amperage can potentially damage your laptop’s battery, charging circuitry, or other vital internal components. This can result in expensive repairs or the need for a replacement.
2. Slow Charging or No Charging: Even if your laptop manages to charge with a phone charger, the charging process will likely be much slower compared to using a laptop charger. In some cases, the phone charger may not provide enough power to charge the laptop at all, especially if you’re using resource-intensive applications.
3. Voiding Warranty: Using a charger that is not recommended or provided by the laptop manufacturer may void your warranty. Manufacturers typically specify the type of charger that should be used with their laptops, and using a phone charger may be considered a violation of the warranty terms.
In conclusion, while it may be tempting to use a phone charger to charge your laptop in a pinch, it’s generally not recommended. The differences in voltage, amperage, and power delivery make phone chargers unsuitable for charging laptops. Attempting to charge your laptop with a phone charger can result in slow charging, potential damage to your laptop’s components, and may even void your warranty.
If you find yourself without a laptop charger, it’s best to seek out a compatible replacement or consider alternative options like USB-C chargers or power banks specifically designed for laptops. Always prioritize the safety and longevity of your laptop by using the appropriate charger recommended by the manufacturer.
Remember, it’s essential to consult your laptop’s user manual or contact the manufacturer for guidance on charging options and compatible chargers.
Frequently Asked Questions
Can a phone charger charge a laptop?
Yes, a phone charger can charge a laptop, but it depends on certain factors such as the charger’s specifications and the laptop’s power requirements.
What are the key factors that determine if a phone charger can charge a laptop?
The key factors include the charger’s wattage, voltage, and amperage ratings, as well as the laptop’s power input requirements. These specifications need to be compatible for the charger to effectively charge the laptop.
Is it safe to use a phone charger to charge a laptop?
Using a phone charger to charge a laptop is generally not recommended. Phone chargers are designed to deliver lesser power compared to laptop chargers. This may result in slow charging, inadequate power supply, and potential damage to the charger, laptop, or both.

However, it is essential to exercise caution and ensure compatibility to avoid any potential issues.
Final Thoughts
A phone charger typically cannot charge a laptop due to differences in power requirements and connector sizes. Phone chargers tend to have lower wattage outputs compared to laptop chargers, which makes them insufficient to power up a laptop. Additionally, laptops usually require a larger connector size than what phone chargers are equipped with. Attempting to use a phone charger to charge a laptop can result in slow or no charging, or even damage to the laptop’s battery or charging circuitry. It is therefore recommended to use the appropriate charger specifically designed for your laptop.
