Can You Charge a Laptop with a Portable Charger?


In the era of constant connectivity, our laptops have become indispensable tools for work, entertainment, and communication. However, their limited battery life can be a major inconvenience, especially when we’re on the go.

Portable chargers, also known as power banks, offer a convenient solution to this problem. They provide a portable source of power that can recharge your laptop without the need for an outlet. But before you invest in a portable charger, it’s important to understand whether it can charge your laptop and what factors to consider.


The first and foremost consideration is whether your laptop is compatible with portable chargers. Most modern laptops can be charged via a USB-C port or a Thunderbolt port. If your laptop has one of these ports, it is highly likely that it can be charged with a portable charger.

Note: Some older laptops may require a dedicated charging port. In such cases, portable chargers may not be able to charge the laptop.

Power Requirements

Once you’ve established that your laptop is compatible with portable chargers, the next step is to determine the power requirements.

  • Voltage: Laptops typically require a voltage of 19V or 20V for charging. Portable chargers can provide voltages ranging from 5V to 20V.
  • Amperage: The amperage rating of your portable charger should be sufficient to provide the required power for your laptop. A higher amperage rating will allow for faster charging.

You can check your laptop’s charger or the user manual to determine the voltage and amperage requirements.

Choosing the Right Portable Charger

Not all portable chargers are created equal. When choosing a portable charger for your laptop, consider the following factors:

  • Capacity: The capacity of a portable charger is measured in milliamp-hours (mAh). The higher the capacity, the more power the charger can store.
  • Power Output: The power output of a portable charger is measured in watts (W). Ensure that the charger’s power output is sufficient to meet the power requirements of your laptop.
  • Ports: The portable charger should have a USB-C or Thunderbolt port that is compatible with your laptop’s charging port.
  • Features: Some portable chargers offer additional features such as fast charging, pass-through charging, and built-in cables. Consider these features based on your needs.
