Keurig’s K-Duo Hot & Iced Gen 2 stands out for its listed 72-ounce reservoir, MultiStream Technology, Strong Brew, and iced setting. The K-Duo Plus is a separate model: consider it if you prefer a 12-cup thermal carafe, programmable brewing, Pause & Pour, or a reservoir that can be repositioned.
“K-Duo” covers different configurations, so this comparison keeps the Gen 2 and Plus distinct. It uses manufacturer-listed features for the Ninja CFP101, K-Duo Hot & Iced Gen 2, and K-Duo Plus. It does not establish which brewer makes better-tasting coffee, lasts longer, or costs less over time.
Which model fits your routine?
- Choose the Ninja DualBrew CFP101 if you want nine grounds brew sizes, four pod sizes, and three named brew styles—Classic, Rich, and Over Ice—in one machine. Its included carafe is glass, and it has an adjustable warming plate.
- Consider the K-Duo Hot & Iced Gen 2 if the listed combination of a 72-ounce reservoir, MultiStream Technology, Strong Brew, and an iced beverage setting best matches what you value. The reviewed product listing does not expose a full specification panel, so details beyond those highlights should be checked in the current manual.
- Consider the K-Duo Plus if you want a 12-cup thermal carafe, a multi-position reservoir, programmable operation, and Pause & Pour. These are Plus features, not features to assume across every K-Duo configuration.
All specifications below are manufacturer listings, not independent test results. Features and availability can change; the cited pages were reviewed on October 7, 2026.
How do their brewing options compare?
| Model | Grounds and pod sizes | Named brew options |
|---|---|---|
| Ninja DualBrew CFP101 | Nine grounds sizes, from a small cup through a full carafe; pods in 6, 8, 10, or 12 ounces | Classic, Rich, and Over Ice |
| K-Duo Hot & Iced Gen 2 | Not stated in the reviewed product listing | MultiStream Technology, Strong Brew, and an iced beverage setting |
| K-Duo Plus | Four sizes for single-cup brewing and four sizes for carafe brewing; the listing gives 6, 8, 10, or 12 ounces/cups | Not stated in the reviewed product listing |
For the CFP101, the range of grounds sizes is useful if you switch between a single serving and a larger batch. Keurig’s Plus listing describes four sizes for each brewing mode. Although both brands offer iced-oriented features on the models listed here, their labels are not evidence that the settings produce equivalent coffee.

SharkNinja describes the CFP101 as brewing “Classic, Rich, and Over Ice” from grounds or pods; that is the manufacturer’s wording, not a comparative taste claim. See the CFP101 product listing and Keurig’s Gen 2 listing and Plus listing.
Reservoirs, carafes, and keeping coffee warm
| Model | Water reservoir | Carafe and warming details listed |
|---|---|---|
| Ninja DualBrew CFP101 | Removable, 60 ounces | 12-cup glass carafe included; adjustable warming plate keeps coffee warm for up to four hours |
| K-Duo Hot & Iced Gen 2 | Single reservoir, 72 ounces | Not stated in the reviewed product listing |
| K-Duo Plus | 60 ounces; multi-position arrangement | 12-cup thermal carafe |
A larger listed reservoir may mean fewer refills for some routines, but actual refill frequency depends on how much and how often you brew. The CFP101’s warmer and glass carafe suit someone who wants coffee kept on a warming plate; the Plus’s thermal carafe offers a different setup. The reviewed product pages do not provide a controlled heat-retention comparison.

Programming, counter space, and day-to-day fit
SharkNinja lists Delay Brew and Keep Warm for the CFP101. Keurig lists programmable operation and Pause & Pour for the K-Duo Plus. The listings do not establish exact scheduling behavior, so consult the manual for the specific model if a particular start time or sequence matters.
For countertop planning, the manufacturer lists the CFP101 at 13.07 inches high by 12.01 inches wide by 17.4 inches deep. The K-Duo Plus is listed at 14.19 inches high by 7.68 inches wide by 15.88 inches deep. Compare width, depth, and overhead clearance against your available space; manufacturers may use different measurement conventions. The reviewed Gen 2 listing does not state dimensions.

Confirm current availability and compatibility before ordering; do not assume parts fit another DualBrew model or a Keurig brewer.
The CFP101 listing specifies a one-year limited warranty. Check the product listing and warranty terms for the applicable region and purchase before relying on coverage details.

Which should you buy?
- Pick the CFP101 when its nine grounds sizes, glass carafe, warming plate, or named brew styles map most closely to how you prepare coffee.
- Pick the K-Duo Hot & Iced Gen 2 when its listed 72-ounce single reservoir and highlighted MultiStream, Strong Brew, and iced setting are the features you want; verify additional specifications for the exact model before purchase.
- Pick the K-Duo Plus when a thermal carafe, multi-position reservoir, programmable operation, and Pause & Pour matter more than the CFP101’s broader listed grounds-size range.
Prices, promotions, stock, and accessory fit are not established as stable comparisons by these manufacturer listings. Confirm the exact model name and current terms on the product page before buying.
