Method 1: Inverter

You can use an inverter to charge your laptop by connecting it to the charging port in your car. Inverters are usually pretty big and have a connection for USBA and a three or two pronged plug.

This means you can plug in most laptop chargers into the inverter which will convert the current to the correct and useable current for your laptop. Keep in mind that everytime it converts the current you lose about 10% of electricity.

There are different types of inverters you can get. Either you can get a small portable one that sits infront of your cigarette lighter port, or you can buy a bulky power inverter which can be connected directly to your car’s battery via a cable and placed in the back.

Here are the steps to charge your laptop with an inverter:

  • Turn on your car’s engine
  • Plug your inverter into your car’s cigarette lighter port
  • Plug your laptop charger into the inverter
  • Plug the cable that runs from your laptop charger into your laptop.

Method 2: Car Laptop Charger

On Amazon and eBay, you can get some pretty cheap car laptop chargers. They are small device that connects to your car’s charging port and they often have a universal adapter cable which is what can be plugged into your laptop for charging.

Here are the steps to charge your laptop with a car laptop charger:

  • Turn on your car’s engine
  • Plug the car laptop charger into your car’s cigarette lighter port
  • Plug the universal adapter end into your laptop to charge.

Method 3: Power Bank

Power banks are a great option to charge your laptop on a road trip. You don’t need to use your car’s battery or plugs at all. You just need to purchase a small power bank and charge it up full of electricity before heading out.

Then all you do is make sure you have a USBA to USBC connector that goes from the powerbank into your laptop. If your laptop doesn’t have a USBC port then get another cable accordingly.

Here are the steps to charge your laptop with a power bank:

  • Plug the USBA head of the cable into the power bank
  • Plug the USBC head of the cable into your laptop.

Method 4: USB Charger

An easy method to charge your laptop in your car is by purchasing a USB laptop charger that is designed for cars and comes with a USBC cable. A lot of newer cars have USB charging ports already built in.

The only thing left for you to do is to change the current to the correct current for your laptop. The easiest way to do that is to use a USB laptop charger.

These chargers are pretty cheap and an easy option if you have a usb port in your car.

Here are the steps to charge your laptop with a USB charger:

  • Turn on your car’s engine
  • Plug the USB charger into your car’s USB port
  • Plug the USBC cable that runs from the charger into your laptop.

Is It Safe To charge a laptop with the car

Yes, its perfectly safe to charge your laptop with the car battery as long as you have an inverter that transmutes the AC current to DC to be able to be used by your laptop.

Sometimes inverters emit electro magnetic waves that can interfere with your car’s computers, but it’s pretty rare that they will have much of an effect. Perhaps on older vehicles it could be a problem, but not on newer ones.

If your car doesn’t start while you are charging your laptop via an inverter, remove the inverter, and then your car should start. Sometimes the inverter messes with your car’s electronics systems.

Cheaper inverters which you can get for around $5-$10 are more likely to cause issues than the more quality ones.

How to charge laptop in car without an inverter

You can charge your laptop in your car without an inverter by using a laptop car charger. These chargers come with a connection to your cigarette lighter port and a USBC or universal adapter cable that plugs straight into your laptop to charge it.

Will charging a laptop in a car drain the battery

No, if your car is moving then a laptop charger connected to your car’s battery will not drain it. However, if your car is stationary or the engine is off then the laptop charger will drain the car’s battery.

While your car is moving, it’s charging the battery itself. This means that you won’t lose any charge in your car’s battery by connecting a laptop to it.

If you use an inverter to charge your laptop and leave it in your car overnight while the engine is off, then it could drain your battery by the morning.

To use the car’s electricity from the battery you will have to convert it from AC to DC by using an inverter. This means you will lose 10% of the electricity current.

Conclusion

Those were the best 5 ways to charge your laptop in your car. Make sure you do most of these methods while the car is running and always unplug your inverter or car charger from your laptop when the car is off to prevent it from draining the battery.
