Methods to Charge Laptop in Car

There are five approaches by which you can quickly charge your laptop inside your car. You may need to buy a few extra things, but it will be worth it.

1. By Using a Laptop charger

One of the best ways to use it at this time is using a laptop charger. Many laptop chargers come with a modified adapter that can easily attach to your car’s outlet. If you can find a charger compatible with your vehicle and your laptop, then this might be your permanent solution.

It is a reasonably inexpensive way to charge your laptop without spending a lot of bucks. If you are trying to find a way to charge a laptop in a car without an inverter, this is the best method you can find online. Go to a store nearby or search online for a charger compatible with your laptop.

2. By using Usb-C

All modern laptops nowadays come with a USB-C port. When you find that there is no other way to charge your laptop, go for this one. You will need a USB-C cable to do so. Plugin the other side into the car’s outlet or any USB port and plug the other USB C type into the laptop. It is an effective way to charge your laptop.

But make sure you check the car’s battery if it is capable enough to charge your laptop. That’s a straightforward approach as most laptops come with a type C charging port. Easy peasy. Now you don’t have to bother about charging your laptop and focusing on what matters: the work.

3. By Using a Powerbank

Another successful way that people use to charge their laptops in the car is by using a Powerbank. It is an affordable way to charge your laptop on the go. But these power banks can sometimes lack the required charge. They can only charge your laptop entirely once or twice according to their capacity.

You can also find some fantastic power banks with high capacity that will be able to charge your laptop even thrice. It depends upon the sum you are spending to buy one for yourself. These power banks have a USB port, so if you can charge your laptop with a USB C type, you won’t face any problems.  Did you know, Why Would not My Laptop Turn On? (Step by Step Guide)

4. By Using an Inverter

The one way to charge your laptop or any other device inside your car is by buying an Inverter. You can find many affordable inverters that can be connected to your car’s outlet. These contain a standard three-plug socket, and some can even have a USB port to connect more devices.

The power of inventors ranges from 150-watts to 1000-watts. The greater the power of the inverter, the more efficiently it will charge your laptop. I will also recommend a few products, so if you are thinking of buying an inverter, the below list will surely help you decide.

Top 3 Best Inverters:

1. Bestek 200 Watt Inverter

The Bestek inverter is one of the best and most common inverters used by people who want to keep their devices charged on their journey. It has a user-friendly design and has two 120V outlets and two USB ports. You can attach up to four devices on it but make sure you don’t, as it might cause a drain in your car’s battery.

The company claims that it has a power efficiency of 92.

2. MaxBoost 300 Watt Inverter

This Maxboost Inverter provides efficient and powerful charging. There are two 110V AC ports along with few other small ports to connect different devices. It has an ideal size that makes it highly portable. This inverter has a robust metal build so that you can think of it as a very durable power inverter. They have also used a technology inside it to avoid overcharging, overheating, and short-circuiting, etc., providing maximum safety.  Did you know, What is the Most Common Pointing Device on Laptops?

3. Ampeak 2000 Watt Inverter

The Ampeak has a powerful 2000 watt power supply that will continuously provide you with a high power surge. You can find three AC to DC outlets. Thus, you can easily attach three devices simultaneously, but make sure to check if your car’s battery is compatible enough to withstand such load. This inverter has all-around protection with two cooling fans and many more features.

Will the Inverter drain my car’s battery?

Yes, they can. If you use an Inverter with a higher watt power, you can end up draining your car’s battery completely. It is recommended that you use an Inverter with the power of 150 to 300 watts. There are inverters with a capacity of over 1500 watts, and if you have the budget, then you can buy that one. You can also use it outside your car during camping or any other place.

Are Inverters bad for the car?

Not really. The power outlet present inside the car only allows 12V that is essential to charge any device. Most cars are compatible with a 150 watts or 300 watts inverter, and if you go above it, it will cause a massive drain in your car’s battery. So make sure to check which inverter is compatible with your automobile.

5. By using an external battery charger

If you cannot afford to use any of the ways mentioned above, then the last thing you can do is externally charge your laptop’s battery. If you don’t have a USB C port on your laptop to charge it, this method will help you a lot.

You may not be able to perform it if your laptop has a built-in battery. You can only achieve it with a removable battery. You only have to pull out the battery and attach it to a charging source. For it, you will need a compatible charger too. If you desire to keep using your laptop, you would have to spend some extra bucks.

Either you buy an external charger or an inverter or an adapter, all of them will be useful for you at some point. If one method fails, use the other, and always remember to pack all the necessary stuff to ruin your trip.
