The Biggest Difference Between Ninja Coffee Bar and Keurig is:

Keurig relies on K-cups for its single-serve brewing. Coffee ground can be used with reusable K-cup filters. Ninja is a pod-free system. You don’t need any type of pods to brew coffee, just your favorite coffee ground.

Cup Size

The Ninja, depending on the model, has 6 or more different cup sizes, meaning that no matter the size of your cup you’ll find the right option for your needs. The Keurig has far fewer brewing options, usually one cup, and up to 3 different cup size options per device. The Ninja is far superior in this category. The different cup sizes allow you to pick and choose your amount of coffee without behind hindered or judged. You can have a tiny cup of coffee, or the biggest cup of coffee in the world without being hindered at all. Your coffee machine should work for you, and with the wide variety of cup sizes you’re going to be easily able to get the perfect cup of coffee out of every morning.

Brew Type

The Ninja Coffee Bar is able to make a wide variety of different brews. From solid bold coffee to iced coffee deliciousness the Ninja is able to do just about everything coffee related. The Keurig though is able to both make a wide variety of coffee and also make hot chocolate and other delicious hot beverages. It can’t make iced coffee though, and you can only choose the different pods to put in, unlike the Ninja, which allows you to brew a wide variety of different coffee types without a specialty pod. All you have to do is put in the coffee flavor you want, start to brew, and prep your taste buds.

Making Drinks Other Than Coffee

The Ninja Coffee Bar’s specialty is coffee. Iced coffee, bold coffee, original coffee, just about any kind of coffee the Ninja can make with very little effort. If you’re looking for something other than coffee the Keurig is the coffee maker to go with mostly because it can make hot chocolate and teas a well. The Ninja can manage to make those things as well, but it is a far more complicated process and you’ll need to clean the Ninja Coffee bar afterward. It’s best just for the Ninja Coffee Bar to stick with what it does best, making coffee. Coffee that rivals all other brews, no matter if its the single serve or carafe that’s brewed.


With the Ninja Coffee Bar you can get a wide variety of additions. The first is an Easy Frother, to get the best foam for your lattes and cappuccinos. Another is a Coffee Caddy, and a Coffee and Spice Grinder. These additions are just a few of the many that can be added onto your Ninja Coffee Bar, giving you a better cup every single morning. These accessories are not mandatory, but they are in fact super useful to each machine depending on the model and accessories you aquire for them. They can make your life much easier, simpler, and more carefree that it would be without them.

The Keurig has a wide variety of additions as well, with a drawer that goes under your Keurig you can also add a moving carousel that can be rotated, adding this near your Keurig displays the pods, but that’s about it. It doesn’t have very many additions at all and it’s rare that the Keurig has any extra additions besides the pod holders. These pod holders come in different sizes and shapes but they all do the same thing, hold Keurig pods. These pods are essential to work the Keurig, but it’s not essential to have them on display.


The Keurig usually costs roughly $100 which is significantly less than the $150 or more than the Ninja, but the Ninja has more additions and capabilities than the Keurig. So for more money you get a much better coffee maker that has variety and strength in each brew. The Keurig though is a cheaper option for those who aren’t terribly fussy over their coffee, and prefer to have a little hot chocolate from time to time. If you want a coffee maker that has the ability to make some okay coffee, along with other hot drinks, the Keurig is for you, but if you want restaurant quality coffee it’s always best to put your trust in a coffee maker that knows what it’s doing.

Which One to Buy

The one you should buy is up to you, it depends on what you want to get from your brewer. Tea, coffee, and hot chocolate are all options with the Keurig but the variety of just coffee products with the Ninja is difficult to pass up. If you only need coffee, tea, hot chocolate and more the Keurig is the best for you. You should also take into account clean up, filters, and other issues when you’re looking into buying either the Keurig or Ninja.

If you’re looking for just a delicious coffee maker the Ninja Coffee Bar is a wonderful addition to any kitchen as long as you need just coffee. Coffee is the focal point of the morning but occasionally wanting some hot chocolate, or tea instead of coffee is a common desire. Depending on if you need coffee or coffee and other hot drinks you should take into account the differences between the Ninja Coffee Bar and the Keurig.

Keurig K145 Coffee Maker

The Keurig K145 is suggested for users who appreciate the “getting used to” of single-cup machines as well as the ease of use and variability that comes along with it.

Below you will learn about all the areas the K145 covers, where it can do better, and who the ideal customer would be.


Like the previous model reviewed, the Keurig K145 also comes with a removable water reservoir. This makes it easy to refill and clean when necessary. Its capacity is 48 Oz. It fits perfectly into the unit, preventing outside dust and particle accumulation. The best part of this feature is the “Drain Brewer” button, allowing you to drain all the water so you can add fresh water.

The drop tray at the bottom of the machine is also easily removable, preventing annoying and time wasting spillage.

The K145 gets high scores for easy cleaning and maintenance.


Keurig revolutionized the coffee world with Flavored K-Cups. The K145 fits standard K-Cups, leaving the barista with hundreds of flavors to look forward to. This variety even features multiple options for tea and lemonade. there is truly something for everyone, not just coffee! Multiple beverage choices via a single machine. Amazing, right?

Further versatility is seen in the multiple cup sizes: 6 Oz. , 8 Oz. , and 10 Oz. Taste also differs among sizes. For seasoned coffee lovers, 8 Oz. features the perfect taste, but at 10 Oz. the coffee has been reported by some users to taste a little weak. With that said, you are free to experiment with multiple flavors and sizes before you find the option that is right for you. You even get a free trial pack of K-Cups with your patronage to Keurig!

It literally takes less than minute to brew a fresh cup. The built-in water reservoir further reduces the time it takes for consecutive cups.

The Keurig K145 suits the efficient American in office.

Built to Stand the Test of Time

The K145 has a heavier and better built housing, making it 2 lbs heavier than the K45. The internal pump is more powerful, reducing the brewing time comparatively. In addition, the heavy-duty power cable adds to its efficiency.

This unit was designed for a small restaurant or office in mind, making it relatively low maintenance and durable.

A frequently voiced complaint is the noise. Given the environment it is typically used in, it does not feature the Quit Brew Technology. This means it could reach loud noise levels. However, it is loudest in the first minute and bearable after that. Even at its loudest, it is still more quite than other kitchen appliances such as a mixer.

Importantly, this model is not compatible with My K-Cup. For baristas who require ground coffee, you are advised to look at other units.


If you prefer single cup coffee and desire an easy hassle free experience, then look no further than the Keurig K145 OfficePRO. It would most definitely be worthwhile to have on your countertop or office space. It is sturdy and doesn’t require much maintenance or cleaning. The design promotes usage of different sizes or flavors (tea and lemonade among others) and delivers reliable taste day in and out.

We would suggest this model over the Keurig K45 due to the features and positive user experience at a relatively higher cost. On the other hand, if your preference is ground coffee and My K-cup, then it is recommended you purchase the K45.

For users who like to begin their day with a steaming hot cup of coffee, the Keurig 2.0 offers programmable settings and would be the preferred machine.

Keurig K-Mini K15 Coffee Maker – Best for Small Space

Keurig K15 Coffee Maker
Keurig K15 Coffee Maker


The Keurig K15  is considered the most cost effective and small K-cup machine. The Mini is 10.8 inches tall and 6.9 inches wide, making it simple to move around. The dimensions make it ideal for people with limited counter-top space. While it doesn’t have carafe capability like the K20 model, the K15 fits all regular K-cups (with and without Keurig brand) and lets you make use of your own ground coffee. The design promotes simple usage, all you have to do is flip open the plastic lid located at the top of the reservoir. Then you use a cup to fill it, pick a K-cup flavor and push the brew button.

This single-use reservoir isn’t suited for everyone. The K15 requires a little time to warm up for each beverage you make. If you are a person who drinks lots of coffee, you would definitely want to spend a little more on a model that can brew multiple cups at once. A model like the K55 would suit you better, as it only needs to heat the water once to brew several cups consecutively.


The unit operation is kept simple. All you have to do is lift the lid off the reservoir, pour in the necessary amount of water and close the lid. Once the handle is lifted, water will begin to pour into the brewer. Once you have waited for all the water to drain, place your favorite K-cup into the holder and shut the handle. Push the Brew button (it will flash blue to notify you). Give the machine approximately 90 seconds to heat the water up and only an additional 20 seconds to dispense the beverage. The total time from brewing to drinking ranges averages about 2 minutes.

The K15 was designed with a single-use reservoir which requires filling for each cup of coffee you desire. This is a feature I did not enjoy at first, but I realized later this is an advantage. It ensures the water is fresh, an important variable when brewing quality coffee. Adding fresh water to the machine couldn’t be any easier. Fill your cup with fresh water, lift the lid and pour it into the machine. The reservoir is even located at the top of the unit for added convenience.

Unlike the other Keurig models mentioned above, the K15 doesn’t have buttons that are designed solely for each cup size. However, there are measurements in the water reservoir that show how much water to add for your desired beverage size. 6,8, or 10 ounces are available. Just add the water and let it reach the appropriate fill level and you’re in business! Simple and effective.

This machine fits all regular K-cups and is also compatible with My K-cup reusable filters. The removable drip tray means it also fits larger mugs.

Customer Service and Maintenance

The Keurig K15 comes with a limited one-year warranty that covers typical home usage. In order to keep your K15 in functional shape, it is suggested you clean the external parts of the brewer regularly. You should descale the unit every 3 ~ 6 months. Luckily, all you must do is detach the brew head which comes off with the click of a button. Customer service is just a phone call away, and is available 7 days a week at 866-901-BREW (866-901-2739).

Features to Consider When You Choose Keurig Models

It can be hard to keep all the different important features in mind when deciding between models. Here is a list that will get you going. Keep in mind your own unique needs when comparing models. These mainly apply to the K-Cup Brewing System models, are also suitable to other models as well.

Where the Machine Will Be Used

Most Keurig models are labeled UL and suggested for Household use only. If you plan on using the machine in an office, commercial building or some dorms you would benefit from a brewer that is listed for commercial use. Read on to learn more about why UL labels matter when choosing a single cup coffee maker.

Machine Size

If you have a tiny counter, you are most likely worried about the amount of space each machine will take up. Another concern might be if it will fit properly under upper cabinets. You can always set up a dedicated brewing station in or near the kitchen. You will find more suggestions and ideas here or on out Coffee Organizers Pinterest board.

Cup Size

Certain machines brew only a single cup size, while other models allow you to choose between 4-12 ounces per cup. Just keep in the back of your mind, the more water you use the milder the taste will be.

Brew Time

Most Keurigs typically only need a minute or less to heat up water from the reservoir and begin brewing. The Mini plus (without a water reservoir) can take 2-3 minutes. This is still much faster than other typical coffee brewing methods. When you add water, it is advised you use water that is room temperature. Otherwise, the wait for your favorite warm beverage will be longer.

Reservoir Build and Size

The Mini plus has a water tank that fits one cup of coffee. This means you must refill the machine each time you use it. The other models have removable reservoirs that makes it easier for you to fill it in your sink. The capacity for these tanks range from 40 to 80 ounces. These models also keep hot water ready for the quickest brewing and dispensing for other purposes.

Hot Water Dispensing

All Keurig Models have the capability of producing hot water for tea, hot chocolate or even instant oatmeal, etc. Some models allow access to this capability better than others. If this is a function that you place a lot of emphasis on, be sure to choose a machine with a hot water button.

Drip Tray

A drip tray is handy for cleaning spills and is typically day to remove. Removing the tray or turning it over usually allows for brewing of taller mugs (like a travel mug).

My K-Cup Usability

Not every machine is suitable for use with the My K-Cup filter (or other similar reusable filters). None of the 2.0 machines or commercial machines do ( the K155 is the exception). If you prefer to use K-Cup, then any Keurig model would best suit you. If you prefer to use your own grind, then the Mini Plus, Elite or OfficePro Premiere (which is also suited for home use).

Quiet Brew Feature

Most models have a feature called Quite Brew technology. This allows for quite coffee making. The only two models that don’t are the K10 Mini Plus and the OfficePro, so these machines are comparatively louder.

Energy Saving

Typical Keurig models have a feature that powers off automatically in 90 seconds after brewing is finished. The OfficePro has an auto shut off after 2 hours.

Programmable Feature

If you look forward to a steaming hot cup of coffee every morning, you can easily program certain models to be ready when you are.

Water Feed Plumbing Kit

The B150 and B155 models feature an optional plumbing kit that allows you to attach a water line to feed the water tank. This saves time and prevents trips to the sink. Do not forget that the B155 was also built for home use.

Water Filtering

You have the option of a water filter that can eliminate distracting tastes if present in your water.
