In today’s fast-paced digital world, staying connected and productive on-the-go is more important than ever. With the rise of remote work, digital nomadism, and constant travel, the need for reliable power sources has become increasingly critical. One of the most essential tools in our mobile arsenal is the humble power bank, capable of juices up our devices on the move. But when it comes to powering a laptop, the requirements are slightly different. So, what power bank can power a laptop?
Understanding Laptop Power Requirements
Before we dive into the world of power banks, it’s essential to understand the power requirements of your laptop. Laptops, unlike smartphones, require more power to operate, with most devices drawing between 40W to 100W. The power consumption depends on various factors, including:
- Screen brightness
- Processor usage
- Battery health
- Device age
To give you a better idea, here are some approximate power consumption levels for popular laptops:
| Laptop Model | Power Consumption |
| — | — |
| MacBook Air | 30W – 40W |
| Dell XPS 13 | 25W – 35W |
| Lenovo ThinkPad X1 Carbon | 35W – 45W |
Keep in mind that these values are approximate and may vary depending on your specific device and usage.
Key Considerations for Laptop Power Banks
When searching for a power bank capable of powering a laptop, there are several key factors to consider:
Capacity
The capacity of a power bank is measured in watt-hours (Wh) or milliampere-hours (mAh). A higher capacity means more energy storage, allowing you to charge your laptop multiple times. For laptop power banks, a minimum capacity of 20,000mAh (74Wh) is recommended.
Tip: Look for power banks with a capacity of at least 30,000mAh (111Wh) for extended laptop usage.
Output Power
The output power of a power bank determines how quickly it can charge your laptop. Look for power banks with an output power of at least 30W, but ideally 60W or higher. This ensures that your laptop receives a steady flow of power, even when running resource-intensive applications.
Ports and Charging Protocols
Ensure the power bank has multiple USB ports, including a USB-C or Thunderbolt 3 port, to accommodate your laptop’s charging requirements. Additionally, look for power banks supporting fast charging protocols like QuickCharge (QC), VOOC, or USB Power Delivery (PD).
Size and Weight
Laptop power banks are naturally larger and heavier than their smartphone counterparts. However, consider a power bank that strikes a balance between capacity and portability.

What is a power bank, and how does it work?
A power bank is an external battery pack that can be used to charge your laptop on the go. It’s essentially a portable charger that can be filled up with power beforehand, allowing you to top up your laptop’s battery whenever you need to. Power banks work by storing electrical energy in a battery, which can then be transferred to your laptop through a USB port.
Most power banks have multiple USB ports, allowing you to charge multiple devices at once. They often come with a variety of charging cables and adapters, making it easy to connect your laptop and start charging. Some power banks also have additional features, such as built-in cables, LED lights, or even solar panels to recharge the power bank itself.
What are the key factors to consider when choosing a power bank for my laptop?
When choosing a power bank for your laptop, there are several key factors to consider. First, you’ll want to think about the capacity of the power bank, measured in watt-hours (Wh). A higher capacity means you’ll be able to charge your laptop more times before needing to recharge the power bank. You’ll also want to consider the type and number of USB ports, as well as the output voltage and current.
Additionally, think about the size and weight of the power bank, as well as any additional features that might be important to you. Some power banks are designed to be ultra-portable, while others may be bulkier but offer more power. You’ll also want to check the compatibility of the power bank with your laptop, as well as any safety certifications or warranties that may be important to you.
How do I know what capacity power bank I need for my laptop?
To determine what capacity power bank you need for your laptop, you’ll want to consider a few factors. First, check the battery capacity of your laptop, usually measured in watt-hours (Wh). You’ll want a power bank with a capacity that’s at least equal to, but preferably higher than, your laptop’s battery capacity. Next, think about how often you’ll be using the power bank and how many times you’ll need to charge your laptop.
As a general rule, a power bank with a capacity of 20,000mAh or higher is a good starting point for most laptops. However, if you have a larger laptop with a higher battery capacity, you may need a power bank with an even higher capacity. Be sure to check the specifications of your laptop and the power bank you’re considering to ensure you’re getting the right one for your needs.
Can I use a power bank to charge my laptop while it’s in use?
Yes, you can use a power bank to charge your laptop while it’s in use, but there are some limitations to be aware of. Most power banks are designed to charge your laptop when it’s turned off or in sleep mode. However, some power banks are specifically designed to support “pass-through charging,” which allows you to charge your laptop while it’s in use.
When shopping for a power bank, look for one that specifically advertises pass-through charging or “power delivery” (PD) capabilities. These power banks are designed to provide a steady flow of power to your laptop, even when it’s in use. However, be aware that not all laptops support pass-through charging, so be sure to check your laptop’s specifications before making a purchase.
Are power banks safe to use with my laptop?
Power banks are generally safe to use with your laptop, but as with any electronic device, there are some precautions to take. First, make sure you’re buying from a reputable manufacturer that adheres to safety standards and regulations. Look for certifications like UL (Underwriters Laboratories) or CE (Conformité Européene), which indicate that the power bank has met certain safety standards.
Additionally, be sure to follow proper usage guidelines, such as keeping the power bank away from water and extreme temperatures. Avoid overcharging or undercharging the power bank, as this can affect its performance and lifespan. Finally, monitor your laptop’s temperature and performance when using a power bank, and stop using it if you notice any unusual behavior.
How do I maintain and prolong the life of my power bank?
To maintain and prolong the life of your power bank, there are several steps you can take. First, follow the manufacturer’s guidelines for charging and maintenance. Avoid overcharging or undercharging the power bank, as this can affect its performance and lifespan. Try to keep the power bank away from extreme temperatures, moisture, and physical stress.
Additionally, clean the power bank regularly to prevent dust and debris from building up. Store the power bank in a cool, dry place when not in use, and avoid stacking it with other devices. Finally, consider updating the power bank’s firmware periodically, if possible, to ensure you have the latest features and improvements.
Can I use a power bank to charge other devices besides my laptop?
Yes, most power banks can be used to charge other devices besides your laptop. In fact, many power banks come with multiple USB ports, allowing you to charge multiple devices at once. This can be especially useful when you’re on the go and need to top up your phone, tablet, or other devices.
Just be sure to check the power bank’s specifications to ensure it can support the devices you want to charge. Some power banks may have specific ports or adapters for certain devices, so be sure to check compatibility before making a purchase. Additionally, be aware of the power bank’s output voltage and current, as well as the input requirements of your devices, to ensure safe and efficient charging.
