One common question that arises, especially for laptop users on the go, is whether it’s possible to charge a laptop using a power bank. The answer to this question is a big ‘YES.’ However, before you are overly excited, there are some things you out to know in order to make the action successful.

1. Understanding Laptop Power Requirements:
Laptops typically have varying power requirements, depending on the make, model, and specifications. The power needed to charge a laptop is measured in watts (W). To find your laptop’s power requirements, check the charger or power adapter that came with your device. It should provide information on the output voltage (V) and current (A). Most laptops require 16V-20V output while most power banks supply 5V USB output.
2. Choosing the Right Power Bank
Not all power banks are created equal, and their compatibility with laptops depends on their output specifications. Look for a power bank with an output voltage and current that match or closely align with your laptop’s requirements. USB-C power banks have become popular for laptop charging due to their higher power delivery capabilities. Ensure that the power bank has sufficient capacity (measured in milliampere-hours or mAh) to provide a full charge to your laptop.
Power banks are rated in terms of capacity, usually measured in milliampere-hours (mAh) or watt-hours (Wh). The capacity determines how much energy the power bank can store and deliver. Higher capacity power banks can provide more charges, but they are also bulkier. Consider your specific needs and the size of the power bank you are comfortable carrying.
3. Check the Connector
Laptops come with different charging ports, and it’s crucial to have the right cable and connector to link your power bank to the laptop. USB-C is becoming a standard for many modern laptops, but some may still use proprietary connectors. Ensure that your power bank comes with the appropriate cables and connectors or purchase them separately.
How to Charge Your Laptop with a Power Bank
- Connect the power bank to your laptop using the appropriate cable and connector.
- Turn on the power bank and ensure it has sufficient charge.
- Your laptop should recognize the external power source and start charging.
- Monitor the charging progress to ensure a steady and safe charging process.
Wrap-Up: As I shared in the introduction of this article, it is possible to charge your laptop using a strong power bank. Also, note that charging protocols are supported by your laptop and the power bank. Some laptops support fast charging or proprietary protocols, and not all power banks may be compatible. That being said, charging your laptop with a power bank will definitely portray different characteristics like slow charge, and battery drain compared to charging from a power source.
