Is It Possible To Charge My Laptop Using A Vehicle’s Electrical System?

Without a doubt, you will require the appropriate laptop accessories. To use the 12V power outlet, you may need a USB Type-C adapter or an AC inverter.

How Many Watts Do You Require For Charging Your Laptop In Car?

Let’s get directly to the point of your question. Determine how much electricity it would require if you installed it in your current vehicle.

The issue is that charging your laptop typically requires 60 to 70 watts. Furthermore, your car’s lighter plug is normally rated at 15 or 20 amps depending on the model.

When 15 amps are multiplied by 120 volts, you get 150 to 180 watts, which is more than enough to charge your laptop while on the go.

If the cigarette lighter outlet in your automobile can produce up to 20 amps, you should expect a maximum current of 200 to 225 watts at most.

You may charge your laptop at the same rate as charging it at home with regular electricity. It will also be charged without incident within a specific time limit.

An inverter is required to charge your laptop while traveling by car. Because it would protect your laptop while still providing it with the necessary current. As a result, it is vital to remember this at all times.

Charging Your Laptop with a USB-C Cable:

Fortunately, most new laptops include a USB-C connector that may also be used to charge the laptop. Furthermore, a dedicated charging connector for external devices is lacking in many recent PCs. You’ll need to plug them into a USB-C port to charge them. Furthermore, the charging port on newer Macbooks has been replaced by a more conventional Type-C port on the bottom.

Make Use Of Any 12V Outlets:

If your vehicle does not have any built-in USB ports, you can connect your device to the 12V cigarette lighter connection. To avoid damaging your laptop, connect it to the wall socket using a USB converter and a USB-C connector.

Charge Your Laptop With A Power Bank:

If your laptop supports USB-C charging, a Power Bank can be used to keep it charged while you’re on the go.

One disadvantage is that it takes a long time to charge the battery. Unless, of course, the output current of your power bank is sufficient. We strongly suggest this Anker Notebook Power Bank due to its amazing performance. It features a 45W USB-C port that can fully charge a laptop.

Charge Your Laptop Using An Inverter:

If your laptop lacks USB-C connectors, you’ll need to use an inverter in addition to the original charger.

To begin, you’ll need an automobile power inverter. You can convert 12V DC electricity from an outlet to 110V AC electricity with this device. You may charge your laptop while on the go by connecting it to the inverter.
