Each laptop includes a built-in battery. You need to supply electricity to the battery to charge it.

They are capable of charging a variety of devices, including laptops. Power banks of this size can be pretty costly, with some exceeding $50 at the time of writing. They are, however, worth the investment due to their ability to charge a variety of different types of devices on a single charge.

A power bank is always helpful to have on hand while travelling or if you cannot charge your laptop. Most power banks include protection features that automatically shut down the unit if it detects excessive heat, overcharging or a short circuit.

Before purchasing or using a power bank on your laptop, ensure that it’s labelled safe for charging laptops. 

Utilize a USB Type-c Power Bank

You can easily use a USB Type-C battery pack depending on the model of laptop you own.

If your computer includes a USB Type-C port, you can use a USB Type-C battery pack in the same way you would for your phone.

Charging in the Automobile

The car’s battery generates electricity, which is used to power various components. If you have the proper tools, you can use the electricity it generates to charge your laptop. All that is required is:

  • For the car adapter, we recommend using a USB Type-A connector to connect to the car and a USB-C connector for the laptop.
  • Most cars now come equipped with a USB charging port. As a result, you may not need to purchase a separate USB car charger.

The procedure for charging a laptop in your car is as follows:

  • To begin charging your laptop, you must start the car’s engine.
  • Connect the USB cable to the charging port on the computer. If you have a car charger, connect the charger and the USB to the car.
  • Plug the USB-C end into the USB-C port on your laptop, and it should begin charging.

It can offer you advantages if you kept an eye on the laptop while charging in the car. Leaving it unattended and exposed to direct sunlight for an extended period can result in theft or overheating.

Using a Battery Charger Externally

External batteries serve as a backup source of power for your laptop’s battery. This method will only work if your laptop’s battery is detachable. Because most external batteries are brand-specific, you will need to purchase one that is compatible with the brand of your computer.

External batteries provide direct power to your laptop’s battery. It’s essentially a tiny cable that connects directly to your battery and then to a wall outlet. These are extremely useful to have on hand if your laptop battery fails to hold a charge or has charging issues.

It is not as effective as it sounds, and you are probably better off purchasing a new laptop charger. Removing the battery from your laptop can be dangerous, and in some cases, it may void your laptop’s warranty.

External battery chargers are roughly the same price as a new laptop charger, so unless you’re committed to charging your laptop in this manner, it’s probably best to purchase a new charger.

As much as we desire this were true, your phone cannot charge the battery on your laptop. While laptops can charge phones, there is no way to charge laptops from phones. The purpose of USB is that only the output port allows electricity to flow. Even if you could reverse the flow, the phone would not generate enough wattage to recharge your laptop’s battery.
