# How Many Watts Does a Laptop Charger Use

Laptops are one of the most popular electronics on the market, and they continue to grow in popularity. One of the main reasons people love laptops is because of their portability. You can take them with you wherever you go, and they’re small enough to fit in most bags. But, one of the downsides of laptops is that they require a charger. And, if you’ve ever wondered how much power those laptop chargers use, you’re not alone.

A laptop charger typically uses between 45 and 90 watts of power. The specific wattage will depend on the make and model of the laptop, as well as the charger itself. Some chargers are more energy-efficient than others, so it is important to check the wattage before purchasing a new one.

The average laptop uses between 15 and 20 watts of power when in use. This means that a laptop charger uses two to three times as much power as the laptop itself. Chargers for other devices, such as smartphones, typically use much less power.

## Why is this Wattage Important?

How Many Watts Does a Laptop Charger Use?

The wattage of a laptop charger is important for two reasons: 1) to make sure that the charger can provide enough power to charge the laptop battery, and 2) to make sure that the charger does not use too much power and cause an electrical hazard.

The wattage of a laptop charger is typically between 45 and 90 watts. The higher the wattage, the faster the charger will be able to charge the laptop battery. However, using a charger with too high of a wattage can cause damage to the battery or the laptop.

It is important to check the wattage of your laptop charger before using it. You can usually find the wattage listed on the charger itself, or in the documentation that came with your laptop. If you are unsure, you can always contact the manufacturer of your laptop or the charger for more information.

### How to Calculate Your Laptop’s Wattage

How Many Watts Does a Laptop Charger Use?

To calculate your laptop’s wattage, you’ll need to know the number of volts and amps your charger uses. The formula for wattage is volts x amps = watts.

For example, if your charger uses 19 volts and 3.42 amps, your laptop’s wattage would be 19 x 3.42 = 64.98 watts.

Keep in mind that the wattage of your laptop’s charger is not always the same as the wattage of your laptop. Some laptops require more watts to charge than others.

If you’re not sure how many watts your laptop charger uses, you can usually find this information on the charger itself or in your laptop’s manual.

### How to Find the Right Laptop Charger

It’s important to make sure you have the right laptop charger for your device. The wrong charger could damage your computer or cause it to overheat. There are a few things to keep in mind when choosing a charger for your laptop.

First, you’ll need to know the wattage of your laptop. This information can be found in the owner’s manual or on the manufacturer’s website. Once you know the wattage, you can choose a charger that is rated for that amount of power.

Next, you’ll need to know the voltage of your laptop. The voltage is typically printed on the laptop itself or in the owner’s manual. Once you know the voltage, you can choose a charger that is rated for that voltage.

Finally, you’ll need to know the amperage of your laptop. The amperage is typically printed on the laptop itself or in the owner’s manual. Once you know the amperage, you can choose a charger that is rated for that amperage.

Once you have all of this information, you can start shopping for the right laptop charger. Be sure to compare prices and reviews before making your final purchase.

### How many watts does a laptop charger use?

A standard laptop charger uses approximately 85 watts of power. This number can fluctuate depending on the make and model of the laptop, as well as the efficiency of the charger itself. Some laptop chargers are designed to be more energy efficient than others, and may use as little as 60 watts of power.

The wattage of a laptop charger is important to consider for a few reasons. First, laptops are typically used on the go, and so their chargers need to be able to work with a variety of different power outlets. Second, the wattage of a charger can affect how quickly it charges the laptop’s battery. A higher wattage charger will typically charge the battery faster than a lower wattage charger.

When choosing a laptop charger, it is important to consider the wattage rating of the charger and match it to the needs of your laptop. A higher wattage charger is not necessarily better, and may even be less efficient, so it is important to choose the right charger for your laptop.
