Laptop wattage

The almost common laptop wattage is 65W.

Based on a written report of 144 of the best selling laptops on the market, laptop wattage ranges from 30W to 200W.

All the same, there are some outliers. It'southward increasingly common to encounter gaming laptops with wattages in backlog of 200W (more on this beneath).

The tabular array below lists the wattage of some of the most popular laptops.

Laptop	Wattage
MacBook Air	30W
MacBook Pro 13″	61W

The wattage listed above is the manufacturer's listed wattage, also referred to as the power rating of the laptop. This is the maximum ability that the device will consume.

Even so, laptops don't ever operate at its maximum power consumption.

The amount of watts that a laptop will really swallow is different from its power rating.

So, next, let'southward accept a look at how many watts laptops really swallow.

How many watts does a laptop actually use?

Based on a study of 1,084 models, laptops use 0.34 watts in Off mode, 0.78 watts in Slumber style, ii.45 watts in Long Idle style and 5.91 watts in Brusk Idle mode, on average, per hour.

The most mutual amount of watts consumed by the all-time selling laptops these days is 65W (max). If Agile manner consumed half of its power rating (which is similar to the results from my exam below), per hour, this laptop would consume 32.5 watt hours of electricity.

Merely how many watts does a laptop use over longer periods of time?

Allow'due south assume, similar to ENERGY STAR, a typical daily usage of 14.3 hours in Off fashion, 0.3 hours in sleep mode and 9.4 hours in combined Idle and high performance modes.

The table below shows how many watt hours laptops use per day, month and year.

Mode	Watt hours used per 24-hour interval	Watts hours used per month	Watts hours used per yr
Off mode	four.88Wh	148.4Wh	one,780.4Wh
Sleep mode	0.23Wh	7.1Wh	85.2Wh
Active style (incl. high performance and active but idle modes)	50.34Wh	one,531.1Wh	1,8373.2Wh
Full	55.45Wh	1,686.6Wh	xx,238.8Wh

These results are based on standardized tests for 1,084 laptops, which were completed for Energy STAR certification. The information, for the 1,084 laptops, was sourced from energystar.gov. Equally a result, these figures relate to the best performing laptops on the market place.

Off mode uses less electricity than Sleep mode. However, due to the estimated elapsing of utilize in each way, Off mode consumes more electricity than Sleep mode per mean solar day.

On average, laptops utilise 55.45 watt hours of electricity per twenty-four hour period. Nevertheless, a consumption of 47.12 watt hours is about common. Overall, under typical usage conditions, laptops eat between 6.iii watt hours and 230 watt hours per twenty-four hour period.

In that location volition exist extreme usage conditions, however. But these results chronicle to typical usage of mod popular laptops.

Per month, on average, laptops swallow 1,686.vi watt hours of electricity, with ane,433.33 watt hours existence the most common. Laptops utilise betwixt 191.67 watt hours and vii,025 watt hours per month.

The amount of watts that laptops consume is more significant when we wait at the almanac figures.

Per year, laptops swallow xx,238.eight watt hours on average, but 17,200 watt hours is nigh common. Laptops employ betwixt 2,300 and 84,300 watt hours of electricity per yr.

The amount of watts consumed per year ranges dramatically. This demonstrates how of import it is to choose an efficient, ENERGY STAR certified, notebook.

How many watts my laptop uses – a real world test

Using an energy monitor / smart plug (bank check out the ane I used on Amazon here), I tested the bodily power consumption of my ASUS VivoBook 14" laptop.

How many watts the ASUS VivoBook uses:

0.33 watts in Off fashion.
3.89 watts in Sleep way.
nineteen.six watts in Active manner while writing on Google Docs.
21.5 watts in Active style while streaming YouTube.
45 watts at max power consumption, according to the manufacturer (I didn't manage to accomplish this wattage).

I obviously didn't complete these tests under the standardized test conditions required to become Free energy STAR certification – I was simply curious.

While I was at information technology, I was curious about how many watts the charger uses while it'southward plugged into the outlet merely non into the laptop. Allow'south take a look at the results of this test next.

How many watts does a laptop charger employ

Laptop chargers can continue to use electricity when they're plugged into the outlet and not plugged into the laptop.

However, the amount of electricity is tiny – a fraction of a watt.

Mod chargers tend to be more than efficient, reducing and, in many cases, eliminating the wastage.

In my case, the laptop charger I tested didn't consume whatsoever electricity when it was plugged into the outlet and not the laptop.

Nevertheless, a flake of a disclaimer is required. My energy monitor merely measures to 2 decimal places of 1 watt. Then the charger could exist consuming 100ths of a watt, but the energy monitor cannot choice that up.

When the charger is plugged into the laptop, power is consumed. This is the "Off way" mentioned above, where 0.33 watts per was being consumed.

Demand help ensuring y'all choose the right laptop charger? Go key laptop voltage details, including safety information, here: Laptop charger voltage – all you need to know.

Sidenote: I see many sources online confusing the charger ability / wattage rating with the amount of watts that it uses. You should expect your charger to not employ any noticeable amount of electricity. When a device is plugged into the charger just it is still in Off mode, you lot can wait the device / charger to draw less than one watt in many / most cases (when the battery is already fully charged).

OK, I've finished with my real-world tests. Let's get back to the written report, where I mentioned "outliers" – the gaming laptops. Let'south briefly take a look at the wattage of these side by side.

How many watts does a gaming laptop use?

Gaming laptop wattage ranges from 35W to 320W, and even more than is some cases. The corporeality of watts used during non-gaming modes is typical – from as depression equally 0 watts in Off mode, to around 20 watts in Idle mode.

However, the amount of watts gaming laptops use during high performance mode is significantly more than typical laptops.

And the amount of watts consumed will vary depending on the specs.

ASUS gaming laptops, specifically their ROG models, have a Total Graphics Power (TGP) that ranges from 35W to 150W, with 115W being the most common. And with a dynamic boost, the GPU power can reach 40W to 150W, with 130W now being the virtually common.Source

Besides, according to tomshardware.com, the Nvidia GeForce RTX 3080 Founders Edition has a 320W TGP.

And that's just the TGP.

Gaming laptops have a massive variety of specs and many are heavily customized.

Two of the best selling gaming laptops on bestbuy.com, the Dell G15 and the Zephyrus xv, have a ability rating of 180W and 200W respectively.

But, as mentioned, actual consumption differs from the power rating.

It wouldn't be unreasonable to call back that off-the-shelf gaming laptops use 2-5 times the corporeality of watts that a typical laptop uses.

When looking at the corporeality of watts that laptops use over long periods of fourth dimension, it's easier to work with kWh. 1 kWh = 1,000 watts.

And yous're billed per kWh of electricity that you eat.

For convenience, to assistance piece of work out the price to run laptops, let's take a look at laptop ability consumption in kWh.

Laptop power consumption (kWh)

The table below lists how many kWh of electricity that laptops use per day, month and year.

Manner	kWh used per 24-hour interval	kWh used per month	kWh used per year
Off fashion	0.0049 kWh	0.1484 kWh	ane.7804 kWh
Slumber fashion	0.0002 kWh	0.0071 kWh	0.0852 kWh
Active mode (incl. high performance and active but idle modes)	0.0503 kWh	1.5311 kWh	18.3732 kWh
Total	0.055 kWh	1.69 kWh	twenty.24 kWh

The data in this tabular array is like to the table immediately above and has the aforementioned usage assumptions.

With the ability consumption in kWh, we can easily work out the electricity cost. Assuming a toll per kWh of fifteen cents (the United states of america average according to Statista):

It costs $0.00825 per mean solar day, $0.25 per month and $3.04 per twelvemonth to run a laptop, on boilerplate.

The results in the tabular array above are the average figures from the study. The low to high power consumption ranges are quite substantial. To get a meliorate sense of how much electricity laptops use and cost to run, let's have a look at these ranges, along with the most common ability consumption.

How much electricity does a laptop apply? (kWh & $ ranges)

Laptops use between 0.0063 kWh to 0.2310 kWh of electricity per day, with 0.0471 kWh being the almost common.

At $0.15 per kWh, it costs from $0.000945 to $0.03465 per day to run a laptop. $0.007065 is the most mutual daily running price for laptops.

Per month, laptops consume between 0.192 kWh and 7.025 kWh of electricity, with one.433 kWh being the most mutual monthly power consumption.

The cost to run a laptop per calendar month ranges from $0.029 to $1.05 ($0.215 is the almost mutual monthly electricity cost).

Annually, laptops use between 2.three kWh and 84.three kWh of electricity, 17.two kWh being the virtually common.

The electricity cost per year to run a laptop ranges from $0.345 to $12.645, with $two.58 being the well-nigh mutual running toll.

So now we know how much electricity a laptop uses. Simply is information technology a lot?

Do laptops use a lot of electricity

No. Laptops exercise not employ a lot of electricity.

They are not considered energy guzzlers.

Laptops use ane,686.6 watt hours (i.69 kWh) of electricity per month, on average.

For perspective, this is equivalent to:

How many watts a microwave uses (specifically, a microwave with a ability output of 1200W) in 1 hour.
How much electricity a dishwasher uses afterward less than 1.v cycles.
How many watts a TV uses subsequently running for nearly 29 hours.

So, when compared to common household appliances at to the lowest degree, laptops do not use a lot of electricity.

Equally a result, they're relatively inexpensive to run, costing just $0.25 per month on boilerplate.
