Ninja PB051 vs CE251: Which Coffee Routine Fits You?

This is a serving-format choice rather than a tested brew-quality ranking. Pick the PB051 for documented single servings with pods or grounds and its four brew styles with a fold-away frother; pick the CE251 for a glass-carafe drip routine with small-batch, Delay Brew and warming-plate controls.

The buying question

Should the PB051’s pod-or-grounds single servings and specialty drink workflow take priority, or does the CE251’s grounds-to-carafe routine fit better?

PB051 gives more ways to make one cup at a time, including pods and a built-in frother; CE251 centers on brewing a carafe with small-batch and scheduled-brew controls.

Quick verdict

When to skip: Your main need is an espresso or bean-to-cup workflow; these two choices are a single-serve pods/grounds brewer and a drip carafe brewer.
When the recommendation changes
  • Your serving pattern shifts from single cups to shared carafes, or vice versa.
  • A scheduled carafe or small-batch setting matters more than pod compatibility, iced brewing or frothing.

The differences that matter

Serving Workflow And Format

Ninja PB051 Single-Serve Pods & Grounds Specialty Coffee Maker (Black)

PB051 makes single servings with pods at 6, 8, 10, or 12 oz, or grounds at 6, 8, 10, 12, 14, 18, or 24 oz; it has a 56 oz removable reservoir and accepts a travel mug up to 8 inches tall.[1, 2]

Ninja Fresh Brew CE251 12-Cup Coffee Maker (Stainless Steel)

CE251 is a drip brewer with a glass carafe; its manual charts 2 or 4 cups with Small Batch and 6, 8, 10, or 12 cups for full-carafe brewing. The manual identifies a 60 fl oz water-reservoir/carafe limit.[3, 4]

What this changes: Choose by how coffee is portioned: PB051 supports one-at-a-time pods or grounds and travel-mug portions; CE251 is organized around brewing grounds into a shared carafe, including small batches. The cup chart is the manufacturer’s brewer scale and should not be treated as 8 oz household mugs.[1, 3]

The better fit depends on your priorities

Brew Customization And Daily Workflow

Ninja PB051 Single-Serve Pods & Grounds Specialty Coffee Maker (Black)

PB051 offers Classic, Rich, Over Ice, and Specialty styles for pods or grounds and includes a removable fold-away frother for hot or cold milk froth.[1, 2]

Ninja Fresh Brew CE251 12-Cup Coffee Maker (Stainless Steel)

CE251 offers Classic and Rich brew controls, a Small Batch setting for 4 cups or fewer, Delay Brew scheduling, and an adjustable warming plate.[3]

What this changes: PB051’s documented controls suit individual drinks with an iced or concentrate-and-froth workflow; CE251’s controls are geared toward timing and serving a carafe. These are different feature sets, not evidence that either machine makes better-tasting coffee.[1, 3]

The better fit depends on your priorities

Best for your routine

One-at-a-time drinks with a pod-or-grounds choice and iced/specialty options

Best fit: Ninja PB051 Single-Serve Pods & Grounds Specialty Coffee Maker (Black)

Based on listed features, not comparative testing.

The PB051 documents single-serving sizes, pod and grounds use, Over Ice/Specialty styles and an included frother; this recommendation is about matching those features to the routine, not measured taste or speed.

Value and trade-offs

The offers shown are per listed package; check the quantities and current terms on Amazon before comparing totals.

Compare the current offers against the feature you will actually use: the PB051’s pod/single-cup and specialty workflow or the CE251’s carafe and scheduling workflow.

Price observations are current-only; there is insufficient price history to assess purchase timing.

Limitations

  • No hands-on brewing or controlled taste, temperature, speed, or reliability comparison was performed.
  • Do not interpret advertised brew styles as evidence that one coffee tastes better.
  • The exact CE251 manufacturer guide and compatible replacement-reservoir page specify 60 fl oz. Use that documented capacity when planning a batch.
  • The manufacturer’s “cup” markings and chart are not represented as standard 8 oz mugs.

Questions shoppers ask

Can the PB051 use either pods or ground coffee?

Yes. SharkNinja lists both for PB051 and gives separate pod and grounds serving sizes; its guide describes installing the matching pod adapter or permanent filter.

Does the CE251 make twelve 8-ounce cups?

The CE251 manual labels its full-carafe chart up to 12 cups and separately states a 60 fl oz reservoir/carafe limit. Treat those markings as the brewer’s own cup scale, not twelve standard 8-ounce mugs.
