While brewing coffee, ever wonder how much energy it consumed per cup? Well, the question is unusual.
But as sensible citizens, this question can tickle in heads of many coffee lovers. If not, there’s no harm knowing that. Instead, that can help you to save some wattage.
Watts usage for a coffee maker
As you prepare one cup of coffee, it takes at least 150 to 450 watts. In one hour, one can easily brew 4 cups of coffee which is equivalent to 800 watts (0.133 kWh). That stands for 80 watts per minute. No wonder, its startup wattage usage is in the range of 600 to 1500 watts.
Well, this is just an overview. To know the details of the energy consumption, an elaborated section is outlined.
Per minute:
To find the watt a coffee maker uses in one minute cannot be identified manually. Instead, you need to do calculations to find that out.
To brew a coffee of one cup, depending on the coffee maker, it most often needs twenty-five to thirty minutes. As one coffee takes a maximum of 450 watts to make one cup, it can be expected to use 80 watts in one minute.
It’s not a big value. But yes, it can build up to a larger value in the long run. However, faster coffee makers can solve this trouble.
Per hour:
Typically, a standard coffee maker has the capability to make four cups of coffee per hour. Thus, it is clear that it might take up to 800 watts.
A generalization format is 0.133 kWh. As this helps us to find the exact cost, it is the most used unit that is needed for reliable comparison.
According to the official value, the US energy consumption chart shows the amount per kWh is not more than 13.19 cents. This is no less than 0.2 cents per hour.
Don’t underestimate it. These small cents can add up to large bills if not taken care of beforehand.
Per day:
People do not drink coffee all day. Not even a coffee fan. Backed up by research, however, this data suggests, that most people in the US drink at least two to four cups of coffee per day on regular basis.
Simply, that makes it a value closer to 800 watts again. But wait! There are occasions too, right? Won’t that make any difference?
Sadly, this can push the values to heaven. For parties and friendly hangouts, a minimum of 2000 watts can be used up in one day. And, that’s quite a lot!
Per month:
Again, back to normal math. If one user drinks four cups of coffee a day and uses at least 800 watts, in a month it can be as high as 24000 watts.
To put it succinctly, the value would be as high as 3.99 kWh per month. Honestly, this value is no less.
Apart from that, occasions can add up to this value and literally shake the expenses. Thus, awareness is what you need.
Startup:
Due to various brands and models out there, it is challenging to say a precise value for this. But a range of values would suffice the curiosity of the users.
Most often the startup wattage value of a regular coffee maker can lie between 600 to 1500 watts. And sometimes even more.
To see the power consumption before is the safest option. And if your one has a lower input than this, you are too lucky.
Will a 1000 watt inverter run a coffee maker?
To function, a lot of people depend on a cup of coffee in the morning. But the catch is without an inverter this simple thing can be tough.
For a regular coffee, an inverter of 750 watts is good to go. Nonetheless, if you want to remain safe, it is often recommended to use at least 1000 watt inverter.
Don’t panic. A 1000 watt inverter will be just a perfect solution for you. Also, keep in mind an increasing consumption of coffee beans can take this level higher.
One common example is an espresso maker. When trying it, one must have an inverter of at least 2000 watts for safety.
How much does it cost to run a coffee maker?
Generally, a coffee maker costs 13.19 cents per minute. Thus, when one makes 4 cups of coffee in one hour it costs 20 cents approximately. Though most coffee makers show this value, sometimes it can be as low as 10 cents and as high as 30.
Keurig:
If you use the Keurig coffee maker, one of the aesthetic pieces of the market, you might need more cash save for it. Initially, it requires a high startup wattage of 1500. That clearly stands for at least 2 cents already.
Cuisinarts:
Other than Keurig, there are Cuisinarts. With the high posh body, it also has energy efficiency power. For this, they often won’t cost you more than 20 US dollars per year.
Single cup:
Well, these are all estimations. However, for a single cup, your coffee maker uses 150 to 300 watts. And as the electricity prices are yet not that expensive, it would not cost you more than 16 cents.
What factors determine coffee maker watt usage?
Although we tried to line up some common coffee maker watt usage, there is no certainty for these. As myriads of factors determine the usage, the power consumption is also varied due to these factors.
Looking at them minutely would help you to find the real correlation between them. Plus, users can know how to limit their power usage through this.
Device Type and Model:
Not all coffee makers are the same. According to the various types, models, and brands, they may use greater power per hour. For instance, Nespresso can use up to 1500 watts per hour, whereas, the Drip brand has a record for only 650 to 800 watts
Energy efficiency:
Most devices, nowadays, have an innovative energy-efficient function. This is really helpful for the users. Unbelievably, this can reduce bills by 50%. Thus if you use these, surely you’ll land with fewer bills at the end of the month.
Frequency:
In case you drink more cups of coffee, sadly this will cost you more power and money. The total cost per month depends on this factor. In addition to this, on occasion or at tea parties, this value can increase drastically.
Amount of coffee beans:
Not all love light coffee. Rather, dark coffees are really trendy nowadays. And without a doubt, for this, you need loads of coffee beans. As a result, to brew such coffee beans, they need greater watts.
But if you are good with the light ones. Stay relieved!
How do I check the power consumption of my coffee maker?
Checking the power consumption of the coffee maker requires simple math. It’s no hassle. Instead, you can ace it with some simple steps.
Identify its voltage and current:
To get the accurate amount of power consumption, try to find out the value of the current and voltage used for each cup. Usually, you’ll find it at the rear part of the device.
However, if you don’t find it there, you can look through the manuals. The information will be indeed provided there.
Multiply to find power:
Now, that’s easy. A simple calculation can help you to find out the power.
At first, multiply the value of current with the voltage amount. Bingo! It is the power the coffee maker needs per cup
Find out the time:
It’s time to find out the time for preparing each cup. Typically, it will be no more than 25 minutes.
Start the stopwatch when you start brewing. As soon as you see your cup is filled, stop the timer. This is the time you spent on each cup
Find energy consumed:
The next step is relatively simple. A simple physics formula is all you need.
Firstly, divide the power value by 1000 to find it in kilowatts. Later on, divide the value by the hour. To exemplify, for 25 minutes use 0.42 hours. The value you got is the energy consumed per cup in kWh.
Find for per month:
To estimate the cost of coffee drinks per month, this calculation is crucial. Thus, it is highly recommended by the experts.
For this, multiply it by the cups of coffee you drink per day. Then, multiplying by 30 is all needed to find out the total consumption per month.
Final Thoughts
Overall, coffee makers do not usually use much energy. Good for coffee lovers. Most often, one cup requires no more than 450 watts, and per day it will not be greater than 800 watts. However, the startup watt can be as high as 1500 watts. Still, this data vastly depends on several other factors.
