This comprehensive guide will provide you with everything you need to know about charging your laptop in your car safely and efficiently.

Is It Safe to Charge a Laptop in a Car?

Yes, it is generally safe to charge a laptop in your car. However, there are a few precautions you should take to ensure the safety of your laptop, car, and yourself.

Safety Tips:

  • Use a high-quality power inverter.
  • Make sure the power inverter is rated for the wattage of your laptop.
  • Do not exceed the power limit of the power inverter.
  • Do not leave the power inverter plugged in when not in use.
  • Avoid charging your laptop in direct sunlight or extreme temperatures.

Methods to Charge a Laptop in a Car

There are multiple ways to charge a laptop in your car, depending on the type of laptop you have and the equipment you have available.

1. Using a Power Inverter with 12V Outlet

This is the most common method for charging a laptop in a car. A power inverter converts the 12V DC power from your car’s battery into 120V AC power, which is compatible with your laptop’s charger.


  1. Connect the power inverter to your car’s 12V outlet.
  2. Plug your laptop’s charger into the power inverter.
  3. Connect the charger to your laptop.

2. Using a USB-C Power Adapter

If your laptop has a USB-C port that supports Power Delivery, you can use a USB-C power adapter to charge it in your car. This method is more efficient and compact than using a power inverter.


  1. Connect the USB-C power adapter to your car’s USB-C port.
  2. Connect the USB-C cable to your laptop.

Charging Compatibility

Not all laptops can be charged in a car. Here’s what you need to check:

Laptop Compatibility:

  • Make sure your laptop has a power adapter that is compatible with 120V AC power.
  • Check the wattage of your laptop’s power adapter and ensure the power inverter you use has a higher wattage rating.

Car Compatibility:

  • Make sure your car’s 12V outlet or USB-C port provides enough power for your laptop.
  • Check the owner’s manual for your car to determine the maximum supported wattage.


Can I charge my laptop while the car is off?
Yes, but it will drain your car’s battery. It’s recommended to only charge your laptop with the car running.
How long does it take to charge a laptop in a car?
The charging time will vary depending on the wattage of your power inverter, the size of your laptop’s battery, and the remaining battery level.
Can I use a regular wall charger to charge my laptop in a car?
No, regular wall chargers are designed for 120V AC power, which is not available in a car. You must use a power inverter or USB-C power adapter.


Charging your laptop in your car is a convenient and practical way to keep your device powered up on the go. By following the safety precautions and using the appropriate methods, you can charge your laptop safely and efficiently. Whether you’re a road warrior, a mobile worker, or simply someone who needs to stay connected while on the move, knowing how to charge your laptop in your car can make all the difference.
