Best Ways to Charge your laptop in Car

How to charge laptops in a car

Working on the move has become the new normal in recent years. Professionals in every profession rely on laptop computers to work and attend meetings while on the road. So you can’t afford for the laptop battery to die.

The issue with a depleted laptop battery in a car is that it cannot be recharged using a standard charger. To connect the laptop charger, you must have supporting accessories that allow you to use the vehicle’s electrical system.

In this post, we will show you how to charge a laptop in your car using several techniques.

Use an inverter to charge a laptop.

To charge your laptop, you typically utilise an Alternating Current (AC) source. A car’s battery, on the other hand, offers Direct Current (DC) energy. You cannot utilise direct current to power an AC-powered item.


In general, a power inverter is a global solution that will function in any car and with any laptop. As an added plus, most power inverters are reasonably priced.

A power inverter fits into the car’s outlet and has two standard three-prong plugs as well as a pair of USB ports for immediately plugging in your laptop’s power adapter. There will also be a few of USB ports for your other portable devices.

However, power inverters have several drawbacks. Their power output may not be enough for your laptop, for example, and low-cost ones do not produce pure sine waves, which might harm sensitive electronics.

Use a power bank to charge a laptop.

A power bank can be used to charge a laptop in the same way that it can be used to charge a smartphone. For a laptop, though, you will need a larger capacity power bank than you would for a smartphone. A power bank’s capacity is measured in mAh (milliampere-hour) and W. (Watts).

A laptop battery requires a minimum of 40W to charge. As a result, you must get a laptop power bank.

If you have a modern laptop with a USB-C or Thunderbolt charging connector, you can charge it in the car without even starting it. You’ll just need a Power Delivery (PD) power bank. Power Delivery power banks have the capacity to charge a laptop via a USB-C connector. Unfortunately, if your laptop has a proprietary charging connector, this approach is not an option.

Use a USB charger to charge a laptop.

A USB laptop charger is another simple way to charge a laptop in your automobile. A Type-C USB laptop charger will provide an exact voltage supply from the vehicle’s battery to the laptop’s battery. This solution, however, is only applicable if your laptop has a Type-C USB connector.

This is similar to using a power bank with PD but you can expect a constant power supply since the power is directly coming from the car’s battery.

Use a laptop charger

Another option is to use a laptop vehicle charger, which, unlike the inverter with a three-pronged plug, is designed exclusively for a specific model laptop. They are just like your laptop charger but they don’t have three-pin. Instead, it directly connects to your car’s charging port.

This solution is very useful but it has a major downside. It is not widely available and it can be unreliable since they do not come with the company’s standard charging input.

Is charging a laptop in your car safe?

It is safe to charge a laptop in a car as long as the proper connections and inverters are used. The danger comes in failing to evaluate the quality or compatibility of charging cables, inverters, power banks, and other devices used for charging. The wrong gadgets might damage your laptop or the electrical outlets in your automobile. As a result, you must exercise caution while selecting a vehicle laptop charger, inverter charger, USB cords, and so on.

Does the car battery get depleted by charging a laptop?

Yes, that is conceivable. Charging a laptop while the car is parked will deplete the battery. Charging a laptop while driving, on the other hand, does not deplete the vehicle’s battery. If you leave a laptop plugged in to charge overnight in a parked automobile, the battery will be significantly depleted.

When the engine is turned off, the battery powers all of the car’s electrical systems. As a result, leaving the headlights on or charging a laptop overnight diminishes the automobile battery.

If you wish to charge your laptop in a parked automobile, your car must have a deep-cycle battery. Unlike a standard automotive battery, a deep-cycle battery recharges fast after being discharged.

Charging your laptop in a car is not easy and straightforward as charging your phone, mainly because of the higher power required by the laptop. If you have a daily use laptop which usually doesn’t need much power, you can use easily use any of these methods to charge your laptop.
