Can You Charge A Laptop With A Power Bank


In today’s mobile world, power banks have become indispensable for keeping our devices powered up on the go. But can these portable chargers also be used to charge laptops? The answer is yes, but it’s not always straightforward. In this article, we’ll explore everything you need to know about charging a laptop with a power bank, including compatibility, efficiency, and practical tips.


1. Power Output

The most critical factor determining compatibility is the power output of the power bank. To charge a laptop, you need a power bank that can deliver enough power to meet the laptop’s power requirements. Most laptops require between 45 and 90 watts of power. Power banks typically provide between 5 and 60 watts, so it’s essential to check the specifications of both devices before attempting to charge.

2. Voltage

The voltage of the power bank should also match the voltage of the laptop. Most laptops use 19 or 20 volts, while power banks usually provide 5, 9, or 12 volts. If the voltages don’t match, you may damage your laptop.

3. Connector Type

Finally, the connector type on the power bank must be compatible with the charging port on the laptop. Most laptops use USB-C or USB-A ports, so ensure your power bank has the appropriate connectors.


1. Capacity

The capacity of the power bank determines how long it can charge your laptop. Measure capacity in milliamp-hours (mAh). A higher mAh rating indicates a more extended charge time. For example, a 10,000 mAh power bank can typically provide about 2-3 hours of charging time for a laptop with a 50 Wh battery.

2. Charging Time

The charging time depends on the power output of the power bank and the capacity of the laptop’s battery. A higher power output will charge the laptop faster, and a larger battery will take longer to charge.

Practical Tips

1. Choose a High-Quality Power Bank

Invest in a reputable brand that offers high-quality power banks with reliable performance and safety features.

2. Check Compatibility

Always check the specifications of your laptop and power bank to ensure compatibility before attempting to charge.

3. Use the Right Connector

Use the appropriate cable and connector to connect the power bank to your laptop.

4. Monitor Charging Progress

Keep an eye on the charging status to avoid overcharging or undercharging.

5. Store Properly

When not in use, store the power bank and cables properly to preserve their longevity.


Charging a laptop with a power bank is feasible with the proper compatibility and efficiency considerations. By following the tips outlined in this guide, you can ensure a safe and effective charging experience. Remember to choose a high-quality power bank, check compatibility, use the right connector, monitor charging progress, and store properly to maximize performance and extend the lifespan of both devices.
