How To Charge A Laptop In A Car?

Last updated Aug 15, 2020

These days everyone is in a hurry due to ever-increasing work that requires caffeinated attention.

Caught in the middle of so many things such as weekend getaway or a family trip or maybe planning a friend’s destination wedding or perhaps just the usual hangout with friends, people carry their old portable yet reliable laptop with them to stream some movies or sort out some office work.

But when they boot up the laptop, they notice that their laptop has only 20% charge left and it looks like they either don’t have time to charge the laptop due to tight schedule or they are away from an outlet.

Have you faced such challenges before? Whatever the reason it is, your laptop’s battery draining is only going to be limiting your productivity, but don’t fear because if there is a will there’s a way and you can actually charge your laptop in a car without having a standard charger on you and if you put it that way it is quite simpler than you would imagine.

So, if you are caught up in such a situation, in this article I have tried my best to list all the ways you could charge your laptop in a car without having a standard charger.

The adapter (power inverter) for rescue

Although it is possible for you to charge up your laptop in the car, it isn’t that straight forward as plugging your charger into the charging port, due to the fact that cars don’t have laptop charging ports but it does have a 12v power outlet which is also called cigarette lighter port through which you can plug an adapter that will help you connect and charge your laptop or your phone.

This unique adapter is called a power inverter which is also considered a universal solution and it is usually compatible with any car and you can find them for a cheap price on the Amazon website. But you should know that you can’t charge your laptop or any other devices if your car’s engine isn’t running.

You can use Samlex PST 120W USB or any other brand to plug it into your cigarette port, and it features three prongs of plugs and a USB ports that can also be connected to laptop directly.

But on the flipside, these inverters can’t be used as permanent or primary charger methods due to the fact that they don’t produce perfect sine waves which can result in battery redundancy damage.

Power bank

If you can’t find a power inverter or want to avoid any damage caused by the power inverter, you can opt-out for a power bank, there are plenty of companies that make power banks big enough to fill your battery juice sufficiently.

They usually have USB type-C which is very efficient and has minimum power loss. Make sure your laptop has a port for USB Type-C to connect in order to charge your laptop through the power bank otherwise this method wouldn’t be of much use to you.

Power banks have plenty of other benefits because you can charge other devices such as mobile phones, tablets, etc. and they also tend to be portable and compact enough to fit into your pocket so you can take it anywhere you like without having it plugged to an outlet.

Universal laptop chargers

These might sound obvious but still, most laptop users aren’t familiar with them. They are specifically designed for these purposes and have an outlet that connects directly to car power ports, though this method eliminates the purpose of having a charging adapter at all which makes this method quite convenient and hassle-free, all you have to do is connect your laptop with the charger, just like you would connect a traditional laptop charger and then plug it into your car outlet.

Please note: there are plenty of car laptop chargers that might have a cheaper price tag but they tend to be less efficient. So, look for a quality charger with good reviews which would be worth the investment.


USB or Universal serial bus is a type of port you would normally see everywhere on digital appliances. They can be used to transfer data as well as charge them.

There are two standard types of USB that are widely used.

  • USB Type-A
  • USB Type-C

A USB type-A is widely used to charge many devices such as phones and tablets but it can’t be used to power your laptop battery, also they are not efficient in providing charge as compared to USB type-C which is a newer and a better technology when compared to Type-A.

Many manufacturers are moving to USB Type-C due to it being highly power-efficient with minimum power loss. Fortunately, it is also used by laptops to charge their battery due to the huge amount of power and wattage they can carry to replenish its battery.

A USB Type-C has an oval shape connector that can also be used as reverse and its main feature is to carry high power at much higher speeds (up to 20 Gbit/s) as compared to a USB type-A (up to 10 Gbit/s).

The connectivity process is simple, all you have to do is make sure your laptop supports USB Type-C connectivity. If it does, all you have to do is plug the USB Type-C charger into your laptop and the other end in the Car power outlet and it will start charging your laptop, it’s just that simple. Make sure your car’s engine is running though.


Although all of these solutions might or might not be helpful depending on your situation, I highly advised you to charge your laptop beforehand because none of these methods are as reliable as charging your laptop in a standard way.

I also advise you to keep an extra pair of batteries in case of an emergency. Furthermore, I have tried to keep this post very straightforward to avoid any mishaps or confusion. Having said that, I hope these tips help you during emergency situations.
