Coffee makers are great. But before having one in your home, you must first know whether your home’s wiring will support it. So, how many amps does a coffee maker use?

The amp usage of a coffee maker is dependent on its features and brand. A 120 volts coffee maker, for example, uses about 5 to 13 amperes of electricity. 2-cup coffee makers utilize about 2.5 to 5 amps. 8 to 10-cup coffee makers generally use 8.3 amps to 12.5 amps.

How Many Amperes Does A 12 Cup Coffee Maker Use?

On average, a 12-cup Keurig brewing machine consumes about 200 watts to 400 watts of electricity. This corresponds to a current usage rate of about 1.37 amps to 3.33 amps. However, when Keurig brewers are in top brewing mode, they peak at about 1500 watts of electricity consumption. This is equivalent to 12.5 amps of current.

In contrast, a 12-cup Mr. Coffee Maker consumes a lesser amount of electricity, about 7.5 amps.

The number of amps used by a coffee maker is dependent on the voltage rating and watt rating. So to know the amp rating of your 12-cup coffee maker, you have to look at the label of the coffee maker.

It is essential to check the rating of your coffee maker before you buy or begin use. This is so that you are fully aware of what you are buying and how much electricity it consumes. In addition, every model of coffee maker has its specifications, which can vary significantly from coffee maker to coffee maker.

Nonetheless, you can find the information in the user manual or the box that came with the coffee maker. If, however, you can’t find the amp rating on the label, you can deduce it. Sometimes, only the power rating in watts is provided; the current in amperes is not included.

Consequently, to know the number of amps your 12-cup coffee maker uses, you need to know the voltage rating of the coffee maker. Most household kitchen electrical appliances are rated 110 volts or 120 volts.

The next step is simple since you know the coffee maker’s watt rating and the voltage. You have to divide the watt rating by the voltage rating to get the current rating in amps.

To illustrate, let’s say you check the label of your coffee maker, and the amp rating is not specified. Nevertheless, the power is indicated as 600 watts. Most kitchen electrical appliances are rated 110 volts or 120 volts.

To get the current in amperes, divide 600 watts by 120 volts. This gives you five amps, and consequently, represents the current used by your coffee maker on average.

How Many Amperes Does A Ninja Coffee Maker Use?

Ninja Coffee Maker

The Ninja Single-Serve Coffee Maker uses about 11.7 amps and is rated 1400 watts and 120 volts. The Ninja Coffee Bar CF091 series, which brews 10-cups, has a rating of 120 volts, 1450 watts, and uses 12.1 amps. In addition, the Ninja Coffee Brewer CE251 has a rating of 120 volts, power of 1100 watts, and uses 9.2 amps.

The number of amps a Ninja coffee maker uses is dependent on the make and model. The machines are of different brewing sizes with various features: the Single-Serve coffee maker, 10-cup coffee maker, 12-cup coffee maker, and other types.

How Many Amperes Does A Bunn Coffee Maker Use?

Bunn Coffee Maker

A Bunn coffee maker typically brews about 4 to 10 coffee cups at a go. Therefore, the amp usage will vary. However, a Bunn Coffee Maker with a rating of 120 volts and 900 watts uses about 7.5 amps of electricity.

Household Bunn coffee makers utilize just above 1 kilowatt of power each day. This will add an extra $5 to your electricity cost every month. It uses this much energy because Bunn coffee machines always need to be plugged in. This is so that the water in the tank is kept hot at all times.

However, if you unplug it when you want to make coffee and plug it back in, the coffee brewed will be cold. This is why the Bunn Coffee Maker is very fast in brewing coffee. In addition, it keeps the water preheated, so you don’t have to wait. Thus, it is recommended for commercial purposes.

Interestingly, you can get an appliance timer and attach it to your Bunn Coffee Maker. The timer will turn it off when you don’t need the coffee maker and turn it back on when you need it.

To illustrate, say you prefer taking your coffee in the morning between 7 am and 11 am. You can set the timer to turn the coffee maker on by 5 am. By 7 am, the water will be hot enough to make coffee.

Afterward, you can set the timer to turn the coffee maker off by noon. Using this method, you can conserve electricity because the coffee maker works for about 7 hours, not 24 hours. Of course, you can alter this timing to suit your time preferences.

How Many Amps Does A 5 Cup Coffee Maker Use?

On average, a 5-cup coffee maker uses about 5 to 8 amps of electricity. This information is usually specified in the coffee maker user manual. If it is not, but the wattage rating is, divide the wattage by the voltage rating. If the voltage rating is not specified, it should be 110 volts or 120 volts.

Furthermore, it is imperative to remember that this value can be more. This is because coffee makers who maintain hot water will consume more current, allowing you to make coffee in seconds. But, again, this is to keep the water at that temperature.

So, unless you need the coffee maker turned on at that time, you should do yourself some good by turning it off. This way, you can save yourself the extra cash that would have gone to your power company.

How Many Amps Does A Single Cup Keurig Use?

keurig coffee machine

A single-cup Keurig with a 120 volt and 1470 watt rating uses about 12.5 amps of electricity to brew coffee from cold water. However, this is only for the heating period. When dispensing or not heating, it uses a maximum of 0.13 amp.

This value, however, depends on the voltage rating of the Keurig coffee machine. This is because devices with a lower voltage rating consume higher amps.

On the contrary, Keurig machines with a higher voltage rating consume less current at a constant wattage rating. Nevertheless, most times, Keurig coffee machines are rated 120 volts.

Do Coffee Makers Use A Lot of Electricity?

On average, coffee makers work for about 10 minutes and make about 4 cups of coffee in the process. This amounts to about 800 watts an hour for an average coffee maker. This equates to about 0.13 kWh or 133.3 Wh. This is low compared to other household electrical appliances like television, microwave, refrigerator, dishwasher, etc.

Yet, they still consume energy because of the way they work. First, they convert electrical energy to thermal energy. This thermal energy is then used to warm the coffee water. They do this within minutes, and some even do this in seconds. This explains why they consume energy.

Most household models consume between 750 watts to 1200 watts, with automatic shutdown happening after about two hours. This corresponds to between 6.25 amps to 10 amps, which means that, on average, each pot of coffee you brew will use about 0.083 kWh of power.

Therefore, a full-sized, average, automatic coffee maker will consume about 730 kWh each year. This amounts to a cost of approximately $87.60 per year or $7.30 per month, assuming the rate is 12/kWh.


The current used by coffee makers is dependent on the model, the number of cups it brews, the power, and the voltage rating. You can know the amp rating of your coffee maker by checking the user manual. If it is not stated, but the power rating is stated, you can get the amp rating by dividing the Watts by 120 volts.
