Ninja Crispi
Ninja · Air fryers · Model FN101 · CRISPi 4-in-1 (series FN101) · Variant: 4-in-1 portable glass air fryer, 3.8 L and 1.4 L glass containers; US 1,500 W Max Crisp version · Markets: US, GB, DE
Ninja's portable glass air fryer as seven reviews across six editorial groups saw it: excellent crisping and easy cleaning, but a 3.8 L capacity, no temperature dial, scorching vegetables and coated crisper plates.
Verdict
Ninja Crispi 4-in-1, verdict. Seven full reviews across six independent editorial groups agree that the glass PowerPod system crisps fries, wings and leftovers as well as a full-size basket fryer, and that cook-serve-store glass is easier to clean. Reviewers split on almost everything else: the 3.8 L and 1.4 L pair suits one or two people, the 4-in-1 has no temperature dial, vegetables scorch, and the crisper plates are coated even though the chamber is not. WIRED scored 7/10, TechRadar and Tech Advisor 4/5, and n-tv made it its glass air fryer test winner. Prices are volatile.
Why medium confidence: 6 independent editorial groups. Score spread (standard deviation) of 4.7 points. Reviewers disagree on a decisive attribute: Capacity, Value. Most qualifying reviews are older than 18 months. Open alerts indicate the evidence may change soon. Only 3 of 6 independent groups publish a numeric score.

What reviewers agree on
- Ease of use · praised by 3 of 6 sources
Which sources said this
- CNN Underscored — positive: The Crispi is described as ridiculously easy to use and, even better, easy to store.
- Ideal Home — positive: The PowerPod itself is described as seamless to use, and the reviewer had no trouble with the two-container workflow.
- WIRED — positive: Plug the unit in, turn it to one of four settings and press go; the reviewer describes the routine as that simple.
Common criticisms
No criticism was shared by enough independent sources to count as consensus.
Where reviewers disagree
- Capacity
· 1 positive, 3 negative, 2 mixed
Which sources said this
- CNN Underscored — mixed: The 4 qt container covered one dinner for a teenager; the piece records no test above that scale.
- Good Housekeeping UK — negative: Framed as a pick for smaller families, couples, meal prepping and office lunches rather than big family dinners.
- Ideal Home — negative: Even the largest 3.8 L container will not suffice for cooking for a crowd, and heavy-duty family cooking is listed as a reason to avoid it.
- n-tv Produkt-Check — mixed: Calls the two containers suitable for families and singles alike, yet its own stacked potatoes came out partly raw, which is the practical ceiling.
- Tech Advisor — negative: Cooking capacity is the one area where it cannot compete with most models, and it is listed as not ideal for larger items.
- WIRED — positive: The two container sizes suit singles and couples, and the reviewer expects the unit to become a regular sight in dorm rooms and tiny apartments.
- Controls and presets
· 1 positive, 3 negative, 1 mixed
Which sources said this
- Good Housekeeping UK — mixed: Roughly five minutes to feel confident with the controls, but only four functions, one compartment and no pre-programmed foods.
- Ideal Home — positive: The only qualifying review stating that the preset time and temperature can be changed with the controls; the manufacturer publishes fixed bands per mode and three other groups disagree.
- n-tv Produkt-Check — negative: No individual temperature setting: the temperature cannot be set or read manually, and there is no shake reminder.
- Tech Advisor — negative: Modes are not adjustable the way a standard oven is, and the reviewer warns that a cheaper three-mode Crispi is sometimes sold in the US.
- WIRED — negative: Four squishy settings and less-than-precise temperature control; the printed per-mode temperature ranges cannot fully be trusted in practice.
- Portability and storage
· 1 positive, 1 negative, 2 mixed
Which sources said this
- CNN Underscored — positive: Compact enough to leave the countertop altogether, which is the point of the glass-container design.
- Good Housekeeping UK — negative: The large container plus the PowerPod weighs around 7 kg; an hour-long commute with it in tow is not something the reviewer would repeat daily.
- Ideal Home — mixed: Much more portable than a typical air fryer, but the reviewer expected a rechargeable battery and found the PowerPod must be plugged into the mains.
- WIRED — mixed: The 1,500 W unit is described as weighing a mere 3 lb or so and fits in some purses, but it still needs mains power rather than a battery.
- Value
· 1 positive, 2 negative, 1 mixed
Which sources said this
- Good Housekeeping UK — mixed: Priced at GBP 179 on Amazon at review time; treated as worth it for its niche rather than cheap against larger basket fryers.
- TechRadar — negative: Value scored 3/5 on the report card, the lowest sub-score, with cheaper no-frills air fryers named as the alternative for bargain hunters.
- n-tv Produkt-Check — positive: Judged good value for money at about EUR 180 in June 2026, on top of winning the four-way comparison.
- Tech Advisor — negative: Cheaper than Ninja's other top air fryers but much pricier than most rivals of the same size, which usually sell well under GBP 100.

What buyers report
What creators showed
Best for
- One or two people in a small kitchen. Tech Advisor, Good Housekeeping UK, Ideal Home and WIRED all frame the two-container system as a couples, students or single-household buy rather than a family one.
- Reheating and re-crisping rather than batch cooking. Recrisp is the mode reviewers single out: WIRED for potluck and office lunches, CNN for fridge leftovers and n-tv for pizza in five minutes.
- Buyers who want a coating-free cooking chamber. The container and lid that touch food are borosilicate glass, not nonstick, with the caveat that the crisper plate sitting inside them is coated.
Skip it if
- You regularly cook for four or more. Four groups call capacity the product's ceiling, and n-tv's own comparative test ended with stacked potatoes still raw in places.
- You want to set a temperature. The 4-in-1 offers four preset modes with fixed bands, and Ninja's later Crispi Pro added the adjustable temperature this model lacks.
- You plan to carry it around. The PowerPod alone is light, but the set with the large container weighs about 7 kg and still needs a mains socket. There is no battery.
- The crisper plates are coated even though the cooking chamber is not. WIRED calls them PFAS-free ceramic, n-tv describes aluminium and then ceramic plates, Amazon DE lists them as nonstick, and a creator says SharkNinja told him stainless steel with a nano-ceramic coating. The exact material is NOT CONFIRMED.
- Function names change by region on Ninja's own confirmation: Max Crisp on the US unit was adapted to Keep Warm for the UK unit, so a US review and a UK review describe functionally different appliances. A cheaper three-mode US version also exists and no source names it.
- Capacity is the sharpest disagreement. Ninja claims the system feeds up to six; Tech Advisor, Ideal Home and Good Housekeeping UK all put it at one or two people, and n-tv's test finished with stacked potatoes raw in places.
- Cleaning is praised and criticised in the same breath. Three groups in three countries independently report food and moisture trapped between the glass and the plastic handles and feet, which are fixed and cannot be removed for washing.
- Price is volatile and market-specific: USD 152.95 in the US, CAD 193.36 in Canada, EUR 179.99 list in Germany and EUR 94 in France in September and October 2026, against USD 159.99 at launch. The 2025 reviews scored a product costing 20 to 40% more.
- Vegetables are the documented weak point. WIRED reports broccoli and zucchini singeing before they cook, TechRadar says raw vegetables come out blackened rather than tender, and n-tv pulled its broccoli at 18 minutes. Ideal Home is the one qualifying review that reports vegetables without complaint.
- Bake mode is deeply assessed by only one group, which browned the top and left the middle raw for thicker items. Whole-chicken results are unresolved too: about 70 minutes with skin that never really crisped.
- Temperature accuracy rests on a single measurement. WIRED found the unit running at least 10 F colder than advertised; no other group measured it, and Ninja's own spec tables contradict its listing titles at 450 F versus 400 F.
- The controls verdict rests on a split the evidence does not close. Ideal Home alone says the preset time and temperature can be changed; n-tv, WIRED and Tech Advisor say they cannot, and Ninja publishes fixed bands per mode.
- The 4-in-1 is no longer the top of its line. Ninja has since shipped the 5-in-1, the Crispi Pro 6-in-1 and 7-in-1 with adjustable temperature and 1,800 W, the Pro XL, a DualZone and a Crispi microwave air fryer, so buyers may be comparing against the wrong model.
- Coverage is uneven in time and discipline. The two numeric scores date from January and March 2025, the newest qualifying review is June 2026, and none of the seven comes from a dedicated food publication: the strongest culinary group, Dotdash Meredith, was unreadable.

How we reached this verdict
7 full professional reviews qualified, representing 6 independent editorial groups, published between Jan 2025 and Jun 2026. Each group counts once and weighs the same; when a group has several titles, their scores are averaged into one. Scores were converted linearly to a 0–100 scale, and the number rests on the 3 groups that publish one; reviews without a score inform the consensus but not the number. Buyer and creator signals are shown separately and are not averaged into the Quorum Score. Research cut-off: Oct 4, 2026. Methodology 1.1. Main limitation: only 3 of 6 independent groups publish a numeric score. Read the methodology.
