Can You Charge Your Laptop with a Power Bank?

When you’re out and about and away from a power outlet, keeping your laptop running can be a challenge. One potential solution is to use a portable battery pack, or power bank. But can power banks actually charge laptops?

Compatibility Considerations

The first thing to consider is whether your laptop is compatible with charging from a power bank. Not all laptops can be charged this way.

  • USB-C Power Delivery (PD): Most new laptops with USB-C ports support USB-PD technology, which allows them to receive power from power banks that also support USB-PD.
  • Proprietary Charging Ports: Some laptops have proprietary charging ports that are not compatible with power banks. For example, Apple’s MagSafe charger cannot be used with power banks.

Charging Speeds

If your laptop is compatible with power bank charging, the next question is how fast it will charge. The charging speed depends on several factors:

  • Power Bank Capacity: Higher capacity power banks can provide more power and charge laptops faster.
  • USB-PD Rating: The USB-PD rating of both the power bank and the laptop determines the maximum charging speed.
  • Laptop Power Consumption: The power consumption of your laptop will affect the charging speed. Laptops with higher power requirements will charge slower.

In general, you can expect a 20,000 mAh power bank with a 60W USB-PD rating to charge a laptop with a 15-inch display at a rate of about 30% per hour.

Tips for Optimal Performance

To get the best results when charging your laptop with a power bank, follow these tips:

  • Use a High-Quality Power Bank: Opt for a power bank with a reputable brand, a high capacity, and a USB-PD rating that matches or exceeds your laptop’s power requirements.
  • Use the Right Cable: Use a USB-C to USB-C cable that supports USB-PD. This will ensure the fastest possible charging speed.
  • Minimize Battery Usage: To charge your laptop more quickly, reduce battery usage by closing unnecessary programs, dimming the screen, and turning off Bluetooth and Wi-Fi.
  • Charge the Power Bank Regularly: To ensure that your power bank is always ready to charge your laptop, keep it fully charged.

Conclusion

Whether or not you can charge your laptop with a power bank depends on your laptop’s compatibility and the capacity and USB-PD rating of your power bank. By following the tips outlined above, you can optimize the charging process and keep your laptop running when you’re on the go.
