Ninja vs Keurig Feature Comparison

1. Choices available for preparing coffee

Both Keurig and Ninja provide a wide range of options for making different types of coffee. The most crucial and standout feature shared by both is the capacity to make a complete glass carafe with 12 cups or single-serve alternatives for coffee extract.

The Keurig coffee machine features separate brew heads that may either make a single cup or an entire pot of coffee. You also can use the Ninja’s single brew head, which, with an adapter, can make coffee hot from either a K-cup pod or ground coffee. Using the carafe indicates that you will require a space where the adaptor may be kept while you are brewing.

2. Options for brewing with a specialty focus

The Ninja is a standout choice regarding unconventional ways of brewing. The Ninja is capable of preparing iced coffee, brewing a coffee concentrate that is quite robust, and even includes a specialty brew option that can be used to prepare beverages similar to espresso.

There is a stronger brew option available with the Keurig, but it does not have any more options for preparing specialty beverages.

3. Water storage facilities

The Ninja coffee bar includes a water reservoir with a capacity of sixty ounces that can be used for both the single-serve and the carafe brewing modes. This will allow you to save time and make your morning routine more straightforward. The Keurig also comes with a water reservoir that holds sixty ounces and may be used for any of the brewing choices.

Both of the coffee makers include a water reservoir that can be removed from the machine, which is a convenient feature. This makes it so that the larger water reservoirs can be easily refilled without relocating the undisputed coffee machine.

The Ninja has a location for the water reservoir that can be adjusted, which is one of its most notable features. Depending on the available space, you can place the removable water reservoir either on the side or the back of the pod-based coffee machine.

4. Size possibilities for carafes of brewed beverage

Carafes that hold 12 cups are included with both of the machines. The carafe of the Keurig is made of glass, but the one that comes with the Ninja may either be made of glass or stainless steel. Both of these machines have the capability of brewing a pot of coffee with 6, 8, 10, or 12 cups.

The Keurig does not have the capability of brewing traditional, rich, or specialty pots of coffee in the carafe as the Ninja does; however, the Ninja does.

5. Options for brewing sizes in K-Cup coffee pods

Four different cup size options are available on a Keurig coffee maker: 6, 8, 10, and 12 ounces. Similarly, the single-serve option of the Ninja may make a cup with a capacity of 6, 8, 10, or 12 ounces.

If you pick one of the non-pod alternatives, the Ninja also has the distinct capability of brewing more giant single-serve cups of coffee. Those individuals who want a bit more strong coffee in the morning will find that the XL cup size, which can hold up to 24 ounces, is the ideal option.

6. Programmable options

Both coffee makers have programmed brewing settings that allow you to select the time up to 24 hours in advance when you would like your more robust coffee to be ready to brew. Put it on automatic mode and walk away!

The Keurig also comes with a technology called “smart start,” which preheats the water and then brews it all in one easy step. There is no need to wait for the simplistic coffee machine to heat up before choosing the size of cup you want the machine to make.

The Ninja coffee maker takes customization to the next level by giving users control over brew time and strength. Due to the adjustable strength settings, you can craft your ultimate cup of joe, no matter if you prefer a light or dark blend.

7. Integrated pausing and pouring function

The Keurig and the Ninja have a function known as “stop and pour” that allows the user to temporarily halt the brewing process to pour a cup of coffee warm before emptying the entire pot. The pause button on the Ninja is not always going to be there. There is a manual switch that you may move over to stop the flow; however, you must remember to move it back to its original position when you have finished stopping the flow.

8. Display

The Keurig coffee machine includes a tiny display panel with a backlight. This screen shows the current time and includes indicators for the cup size and brew strength. The Keurig coffee maker features a display that provides all the same information as the Ninja coffee maker, plus it tells you how many cups or ounces of coffee it will brew. The display on the Ninja coffee maker is large and simple to see.

In addition, the front panel of the Ninja display has an innovative feature of the clock so that you can quickly keep track of the current time.

9. Dimensions

The Keurig coffee maker has a height of 12.92 inches, a width of 10.94 inches, and a depth of 12.76 inches, whereas the Ninja coffee maker has dimensions of 11.39 inches in length, 9.13 inches in width, and 15.54 inches in height.

10. Frother for milk

A frothing arm is included in the design of the Ninja DualBrew entire coffee machine. You won’t be able to create hot milk drinks with it because it doesn’t have a heater, but you’ll have no trouble making cappuccinos or lattes with it. The fresh milk frother that comes with the Keurig K-cafe coffee machine is missing in action.
