If you’re having trouble figuring out how much power your laptop is using when charging, then this is the article for you.

• How many watts does my laptop use when charging?
• How much electricity do laptops use?
• How many amps does a mobile phone charger have?

These are all questions about wattage.

The answer to “How many watts does a laptop use when charging?” can be found at the source of most chargers, the AC adapter.

An AC adapter converts household current (120V @ 60Hz) into low voltages that charge the internal components of the computer or device that it’s connected to.

Laptops are especially picky about their adapters because they require specific types of voltages in order to function correctly.

Typically, laptop adapters are anywhere between 18-20 volts, with that said, laptops can also accept 19 or 20 volts (depending on the wattage of the adapter).

Anything above or below that voltage is too great for most laptops to handle without doing some damage.

This is why you’ll find an AC adapter labeled with “Input: 100-240V” if you decide to look up the technical specs of your device. The more widespread range (100-240) allows room for voltage fluctuations during travel while still providing steady power to the battery.

Consequently, this makes it more difficult to calculate exactly how many watts an AC adapter puts out since there are more variables involved in determining its output than that of a normal household outlet.

## Central Processing Unit

Before we get into the watts used by different parts of your laptop, it’s important to understand what “Watts” actually are.

Watts (W) measure energy use over time, also known as power consumption.

This isn’t something you should be worried about when estimating how much wattage your laptop uses while charging, fortunately, these details are usually included in technical specs of AC adapters.

Knowing this will give you more insight on how many watts does my laptop use when charging?

Let’s find out.

## Dual graphics card

It can be helpful to know exactly how much wattage used by each component inside of our laptops, so that we can understand why they don’t work when we’re not within our house.

The power needs of these devices vary greatly, so let’s start by looking at one of the most energy-intensive components inside of your laptop, the graphics card.

Dual graphics cards are becoming more popular as technology advances and consumers continue to demand more from their hardware-based electronics.

There may be times where you’d rather play your games on an external monitor instead of your primary screen, but one thing remains consistent with this setup, both screens require energy.

The motherboard supports both graphics cards, which are then connected to their own respective power supplies that are called “e-GPU”.

Dual graphics card setup uses more energy, so it’s important to note how often you’re using this feature while working on your computer. If the e-GPU is being used daily or you’d like to save some money on your monthly electric bill, then it would be beneficial for you to look into a laptop that doesn’t have this feature or one that only has the GPU built into it.

## Central Processing Unit

Now, let’s take a look at the Central Processing Unit (CPU) inside of your laptop and how it affects your power consumption while you’re operating on battery life.

The wattage consumed by the CPU is largely based on its speed and type.

In addition, there are other factors affecting the wattage used by your CPU such as the operating system, background processes, and more.

## Conclusion

The most important thing to consider when it comes charging your laptop is how many watts of power an appropriate adapter will provide.

For example, if you have a wander weight battery that only supports up with low-wattage charges then this could become limiting in terms of speed and efficiency because there’s not enough food for all components involved so make sure before purchasing any accessories such as chargers or batteries know exactly what their total requirements are.
