When I compare single-serve coffee makers with built-in frothers, the key choice is whether you want drink customization, coffee flexibility, or a compact all-in-one setup. The Ninja PB051 stands out for its large 56-ounce reservoir and pod-or-grounds brewing; the Keurig K-Café SMART is the pick for app controls and adjustable drink settings; and the Tastyle K330MF models offer four brew styles and a detachable frother in a more straightforward package.

The tradeoffs are practical: the Keurig limits you to K-Cup pods and relies on WiFi for app features, while both Tastyle versions and the Ninja accept grounds as well as pods. The Ninja needs more counter space than the compact Tastyle brewers, and the two Tastyle listings share a model name and feature set but differ in color and listed wattage. I’ve ranked them by how well their frother, brew options, and day-to-day convenience work together—not by feature count alone.

Key Takeaways
- Ninja PB051 is the most flexible choice for pod and grounds brewing, with a 56-ounce reservoir and a fold-away frother.
- Keurig K-Café SMART gives the most drink adjustment, including five strength settings, six temperature settings, and hot or cold frothing.
- Both Tastyle K330MF listings offer four brew styles, six cup sizes, a detachable frother, and a 40-ounce removable reservoir.
- The black Tastyle listing specifies 1,000 watts, while the red listing says 10,000 watts; check the product listing because that spec is inconsistent with the other model details.
- Choose by routine: the Ninja for grounds flexibility and fewer refills, the Keurig for connected customization, or Tastyle for a compact, simpler setup.

More Details on Our Top Picks
Ninja PB051 Pods & Grounds Specialty Single-Serve Coffee Maker with Built-In Milk Frother
The Ninja PB051 earns my top spot because it balances the two parts of this category that most affect everyday use: coffee choice and milk preparation. It brews with K-Cup pods or fresh grounds, offers four brew styles, and has a fold-away frother for hot or cold foam. Compared with the Keurig K-Café SMART, it does not offer the same app-based scheduling and extensive temperature adjustment, but it avoids tying the owner to K-Cups alone.
Its 56-ounce removable reservoir is the largest listed here, a useful advantage for a household making several drinks before refilling. The machine also accepts travel mugs up to eight inches tall and brews servings up to a 24-ounce travel-mug size. That makes it more adaptable than the K-Café SMART’s listed maximum 12-ounce brew size, and slightly more accommodating for tall mugs than either Tastyle’s 7.3-inch clearance.
The tradeoff is a larger footprint than the compact Tastyle options, plus plastic construction rather than a more premium-feeling material. Its fold-away frother keeps the setup tidy when not needed, but milk residue still calls for regular cleaning. I’d choose it for a mixed pod-and-grounds household; I’d skip it if counter space is the main constraint or connected drink controls matter more than coffee-input flexibility.
Pros:- Brews with K-Cup pods or fresh grounds.
- Large removable 56-ounce water reservoir.
- Fold-away frother supports hot and cold foam.
- Fits travel mugs up to eight inches tall.
Cons:- Plastic construction may feel less premium.
- Bulkier than the compact Tastyle options.
- Frother needs regular cleaning to clear milk residue.
Best for: People who alternate between K-Cup pods and fresh grounds, make multiple drinks between refills, or use taller travel mugs.
Not ideal for: Buyers with very limited counter space or anyone who prioritizes WiFi controls and scheduled app brewing.
- Coffee compatibility:K-Cup pods and grounds
- Brew styles:Four
- Cup range:6 oz to 24 oz travel-mug serving
- Water reservoir:56 oz, removable
- Frother:Fold-away, hot and cold froth
- Travel mug clearance:Up to 8 in
- Power:1500 W, 120 V AC
Our verdict“I’d choose the Ninja PB051 for the strongest balance of brewing flexibility, reservoir capacity, and built-in frothing.”
Keurig K-Café SMART Single-Serve Coffee Maker with WiFi and Built-In Frother
If personalizing drinks matters more than choosing among coffee formats, the Keurig K-Café SMART is the clear alternative to the Ninja. It brews K-Cup coffee and pairs it with a built-in frother that offers three speeds and a cold setting. Five strength settings and six temperature settings give it more listed drink adjustment than either Tastyle machine, making it a good fit for people who regularly switch between milder coffee, stronger cups, and milk-based drinks.
Its connected features support remote and scheduled brewing through the Keurig app, with Alexa and Google Home compatibility also listed. That feature set gives it a different role from the button-operated Ninja and Tastyle machines: the Keurig is aimed at buyers who want more control from a phone or voice assistant. The catch is that WiFi is required for app features such as BrewID and Barista Mode, so buyers who prefer an uncomplicated offline appliance may not get much value from the added connectivity.
The biggest functional compromise is K-Cup-only brewing. Unlike the Ninja and both Tastyle models, this machine does not offer a grounds option in the supplied details. Its listed brew sizes also top out at 12 ounces, while the other models reach 24 ounces. I’d put it ahead of the Tastyle brewers for connected customization, but behind the Ninja for flexibility and larger servings. Choose it for app-led routines, not for grounds brewing or oversized mugs.
Pros:- Built-in frother has three speeds and a cold setting.
- Five strength and six temperature settings.
- Supports remote and scheduled brewing through the app.
- Works with Alexa and Google Home.
Cons:- Limited to K-Cup pods in the listed specifications.
- App features such as BrewID and Barista Mode require WiFi.
- Listed brew sizes stop at 12 ounces.
Best for: K-Cup drinkers who want adjustable strength and temperature, hot or cold frothing, and app-based scheduling.
Not ideal for: People who want to brew fresh grounds, avoid WiFi-dependent features, or make larger single servings.
- Coffee compatibility:K-Cup pods
- Brew sizes:2, 4, 6, 8, 10, and 12 oz
- Frother:Built-in; three speeds and one cold setting
- Strength settings:Five
- Temperature settings:Six
- Connectivity:WiFi and Keurig app
- Voice assistants:Amazon Alexa and Google Home
- Dimensions:12.1 x 11 x 17.2 in
Our verdict“I’d pick the K-Café SMART when connected controls and drink customization matter more than grounds compatibility or large servings.”
Tastyle Single-Serve Coffee Maker with Detachable Milk Frother, Black
The black Tastyle K330MF makes the most sense for buyers who want a compact, flexible brewer without making app controls the center of the experience. It handles K-Cup pods and grounds, gives six cup-size choices from 6 to 24 ounces, and has Classic, Bold, Over Ice, and Specialty settings. Those options put it closer to the Ninja than the K-Café SMART in coffee-input flexibility, though its 40-ounce reservoir is smaller than Ninja’s 56-ounce tank.
The detachable milk frother is useful for buyers who want to move or clean the frothing component separately. That differs from the Ninja’s fold-away arrangement, which stays attached to the machine, and from the Keurig’s integrated setup with speed and cold-froth controls. Tastyle’s design is the simpler fit for a kitchen where a removable frother is preferred over connectivity or more detailed milk settings.
Its travel-mug clearance is listed at 7.3 inches, below Ninja’s eight inches, and the body is plastic. One specification deserves a careful check: this black listing gives the brewer as 1,000 watts, while the near-identical red Tastyle listing states 10,000 watts. Since the models share the K330MF name and many core details, I would verify the exact listing before treating that difference as reliable. This is a practical pick, but not the one I’d choose for the biggest reservoir or the most refined control set.
Pros:- Works with K-Cup pods and ground coffee.
- Four brew styles and six cup-size options.
- Detachable frother and removable 40-ounce reservoir.
- Fits travel mugs up to 7.3 inches tall.
Cons:- Plastic construction is less premium than metal.
- Smaller reservoir than the Ninja PB051.
- Listed wattage differs sharply from the red K330MF listing.
Best for: Buyers who want a compact pod-and-grounds machine with several brew choices and a frother that detaches for cleaning or storage.
Not ideal for: People who need the largest reservoir, travel-mug clearance above 7.3 inches, or app-connected drink controls.
- Coffee compatibility:K-Cup pods and grounds
- Brew styles:Classic, Bold, Over Ice, Specialty
- Cup sizes:6, 8, 10, 12, 16, and 24 oz
- Water reservoir:40 oz, removable
- Frother:Detachable milk frother
- Travel mug clearance:Up to 7.3 in
- Listed power:1000 W, 120 V
- Other features:Auto clean, auto shut-off, descaling reminder
Our verdict“I’d choose this black Tastyle for a compact, adaptable coffee-and-frother setup, after verifying the wattage on the exact listing.”
Tastyle Single-Serve Coffee Maker with Detachable Milk Frother, Red
The red Tastyle K330MF shares the black model’s core appeal: one compact machine for pods or grounds, multiple serving sizes, and a detachable frother. I see its strongest case in the combination of four brew styles—Classic, Bold, Over Ice, and Specialty—and six sizes reaching 24 ounces. Compared with the K-Café SMART, it accepts grounds and supports larger listed servings; compared with the Ninja, it uses a smaller 40-ounce reservoir and has less travel-mug clearance.
For a buyer who wants iced coffee and specialty-style options alongside everyday brewing, Tastyle provides more listed brew-style choices than the Keurig’s description specifies. Its removable tank and dishwasher-safe parts also suit someone who wants a relatively simple cleaning routine. The detachable frother can be taken off rather than left folded against the machine, though that convenience also means it needs to be handled and cleaned as a separate component.
This model is not a meaningful feature upgrade over the black Tastyle listing: both carry the K330MF model name and nearly identical brew and reservoir details. The red version’s listed wattage is 10,000 watts, versus 1,000 watts for the black listing, an unusually large discrepancy that should be checked against the seller’s current specifications. Its plastic body and maximum 7.3-inch mug clearance are also limits. I’d select it for its listed color and shared compact feature set, not because the available details show it outperforming its black counterpart.
Pros:- Brews with K-Cup pods or grounds.
- Includes four brew styles and six cup sizes.
- Detachable frother and removable 40-ounce reservoir.
- Dishwasher-safe parts and automatic cleaning features are listed.
Cons:- Plastic construction.
- Brews up to 24 ounces at a time and fits mugs up to 7.3 inches.
- Listed 10,000-watt figure conflicts with the near-identical black model.
Best for: Buyers who want a red, compact brewer with pod-and-grounds flexibility, multiple brew styles, and a removable frother.
Not ideal for: Anyone expecting a clear feature advantage over the black K330MF, or who needs a large reservoir or extra-tall mug clearance.
- Model:K330MF
- Coffee compatibility:K-Cup pods and grounds
- Brew styles:Classic, Bold, Over Ice, Specialty
- Cup sizes:6, 8, 10, 12, 16, and 24 oz
- Water reservoir:40 oz, removable
- Frother:Detachable milk frother
- Travel mug clearance:Up to 7.3 in
- Listed power:10000 W, 120 V
Our verdict“I’d consider the red Tastyle for its color and flexible compact setup, but I would verify its listed power specification before choosing it over the black version.”
How We Picked
I ranked these machines around the needs behind this specific search: making one serving of coffee and adding frothed milk without needing a separate countertop appliance. I looked at brew input flexibility, cup-size range, reservoir capacity, frother configuration, drink controls, and the likely cleaning and counter-space tradeoffs. A frother matters most when it fits the buyer’s routine, so I distinguished detachable and fold-away designs from the Keurig’s integrated hot-and-cold frothing setup.
I also compared each machine against the others rather than treating a longer feature list as an automatic win. For example, the Keurig has more app and temperature controls, but its K-Cup-only setup is less flexible than the Ninja and Tastyle machines. The Ninja’s large reservoir helps frequent brewers, while Tastyle’s smaller footprint and detachable frother favor buyers who want a simpler arrangement. The supplied specifications include a questionable 10,000-watt figure for the red Tastyle listing, so I flag that discrepancy rather than treating it as a meaningful advantage. I did not infer performance beyond the provided product information.

Factors to Consider When Choosing Singleserve Coffee Makers With Builtin Frothers
I’d decide among these four by matching the machine to the drink routine, rather than treating every built-in frother as equivalent. The main differences are coffee input, frother design, drink controls, and refill frequency. Those factors matter more here than a long list of settings if they do not fit how you make coffee.
Choose between pods and grounds
The Keurig K-Café SMART is the straightforward choice for a K-Cup household, but its supplied specifications list no grounds option. Both Tastyle K330MF versions and the Ninja PB051 accept pods and ground coffee, which lets you use convenient single servings one day and your preferred grounds another. If you want that flexibility, I’d narrow the list to those three first. The Ninja and Tastyle models all reach a listed 24-ounce serving, while the Keurig’s listed sizes stop at 12 ounces.
Match the frother design to cleanup
The two Tastyle brewers have a detachable frother, which can be removed instead of remaining attached to the machine. Ninja uses a fold-away frother that tucks out of the way but still needs regular cleaning. Keurig’s built-in frother offers three speeds and a cold setting, which gives buyers more stated frothing control than the product details provide for Tastyle. I’d prioritize a removable component if separate handling suits your routine, and the Keurig if you specifically want hot-and-cold frothing settings.
Compare reservoir size and counter fit
Reservoir capacity shapes how often you stop to refill. Ninja lists 56 ounces, ahead of Tastyle’s 40 ounces; the Keurig capacity is listed as 1100 ml. That gives Ninja the clearest advantage for several drinks between refills. The tradeoff is footprint: Ninja is described as bulkier than the compact Tastyle options. Check the available counter area and cabinet clearance, especially for the Keurig, whose listed height is 17.2 inches. Mug fit matters too: Ninja allows up to eight inches, while Tastyle lists 7.3 inches.
Decide whether connected settings will get used
K-Café SMART adds WiFi, app features, scheduling, and voice-assistant compatibility, along with five strength and six temperature settings. Those controls make it the most customizable option on paper, but app features such as BrewID and Barista Mode require WiFi. The Ninja and Tastyle machines offer a more button-led approach in the supplied descriptions. I’d choose the connected Keurig if remote or scheduled brewing is part of the routine; otherwise, its extra controls may not offset its K-Cup-only format.
Treat the Tastyle wattage mismatch carefully
The red and black Tastyle listings share the K330MF name and nearly all described features, yet their power figures differ sharply: 10,000 watts for red and 1,000 watts for black. I would not use this discrepancy as a reason to rank either model ahead of the other. Confirm the current product details for the exact color and listing before buying. Both versions are described as plastic, use a removable 40-ounce reservoir, and provide six cup sizes and four brew styles.
Frequently Asked Questions
Which of these machines can brew both pods and ground coffee?
The Ninja PB051 and both Tastyle K330MF listings are described as compatible with K-Cup pods and grounds. The Keurig K-Café SMART is listed for K-Cup pods. If you want the option to use loose grounds without switching machines, choose among Ninja and Tastyle; Ninja has the larger reservoir, while Tastyle is positioned as the more compact setup.
Which coffee maker has the largest water reservoir?
The Ninja PB051 lists a 56-ounce removable reservoir, the largest capacity in this group. Both Tastyle models list 40 ounces, and the Keurig lists 1100 ml. A larger tank can mean fewer refill stops when making several drinks, though the Ninja is also described as bulkier than the compact Tastyle options.
Do all four frothers make cold foam?
The product details explicitly describe hot and cold frothing for the Ninja PB051, and the Keurig frother includes a cold setting. The Tastyle descriptions identify a detachable milk frother but do not specify hot or cold modes. If cold froth is a deciding feature, the supplied specifications make Ninja and Keurig the clearer choices.
Which model is best for a travel mug?
The Ninja PB051 has the greatest stated clearance at up to eight inches. Both Tastyle models list clearance up to 7.3 inches. The Keurig specifications do not state travel-mug clearance, so I would check the machine and mug dimensions before relying on that pairing. Ninja also lists a serving size up to 24 ounces, which better suits larger travel drinks than Keurig’s 12-ounce maximum.
Why do the two Tastyle listings show different wattage?
The red Tastyle listing gives 10,000 watts, while the black listing gives 1,000 watts, despite both being identified as model K330MF with similar features. The supplied information does not explain the difference, so I would verify the power specification on the exact listing before purchasing. Their shared features include four brew styles, six cup sizes, a 40-ounce removable reservoir, and a detachable frother.
Conclusion
For the widest mix of pod and grounds brewing, larger servings, and fewer reservoir refills, I’d choose the Ninja PB051. K-Cup drinkers who want app scheduling, voice-assistant support, and more strength and temperature adjustment are better matched to the Keurig K-Café SMART, provided WiFi-dependent features and pod-only brewing fit their routine. If compact size and a detachable frother matter more than connected controls, either Tastyle K330MF is a reasonable fit. I’d compare the red and black listing details carefully, especially their conflicting wattage figures, before choosing between those near-identical options.
