As an Amazon Associate, The Counter Lab earns from qualifying purchases. We don’t do hands-on testing and we don’t accept free units.

Cosori and Ninja are the two brands that dominate the basket-style air fryer shelf, but they win on different spec sheets. Cosori’s verified picks lead on warranty length and published detail per dollar. Ninja’s lead on raw wattage and on the only true dual-basket design in our comparison. Here is how the five fryers we’ve fully verified stack up — and which one fits which kitchen.

The models we’re comparing

From Cosori: the TurboBlaze 6.0-Qt (CAF-DC601-KUS), our best-overall pick, and the compact Lite 4.0-Qt Smart (CAF-LI401S-AUS). From Ninja: the Air Fryer Pro 4-in-1 (AF141) and the two-basket DoubleStack XL (SL401). Sitting outside both brands as a premium reference point: the Typhur Dome 2 (AF05).

Head-to-head

One number is missing from most of this table on purpose: noise. Only Typhur publishes a noise figure (51 dB, from its product page). Neither Cosori nor Ninja publishes one for these models, so we leave it blank rather than estimate it.

Where Cosori is stronger

Pros (brand level)

• Warranty: both verified Cosori picks carry a 2-year limited warranty — twice the term of both Ninja picks at similar prices.
• Specs per dollar: the TurboBlaze pairs the widest verified temperature range here (90–450°F) with the lowest verified price in the comparison, $89.99.
• Published detail: Cosori publishes full dimensions, weight, wattage and voltage on its own pages, which makes counter-fit checks possible before you buy.
• Small-and-smart option: the Lite is the lightest fully verified pick here (9 lb) and the only sub-$100 model with app control (VeSync, with Alexa/Google support).

Cons (brand level)

• No dual-basket model in our verified set: cooking a main and a side at the same time means batches on a single-basket Cosori.
• No published noise figures on either pick.

Where Ninja is stronger

Ninja is the bigger, more established name in this category, and on the specs we verified it earns that position in two specific places rather than across the board.

Pros (brand level)

• Top wattage in the class: the AF141’s 1,750 W is the highest in the under-$100 group.
• The dual-basket answer: the DoubleStack XL stacks two independent 5-qt baskets vertically — two foods at two temperatures in a 13.07-inch-deep footprint, where side-by-side dual baskets would sprawl.
• Counter-friendly depth: the AF141 is only 10.55 inches front-to-back, slimmer than most 5–6 qt baskets and easier under low cabinets.
• No account required: the AF141’s 4-in-1 controls work without an app sign-up.

Cons (brand level)

• 1-year warranties on both picks — half of Cosori’s coverage at the same money.
• Availability caution: the AF141 was flagged out of stock on the manufacturer’s own page when we read its price, so check stock before planning around it.
• Spec gaps: Ninja does not publish a temperature range for the SL401 on the page we read, and publishes no noise figures either.
• The SL401 is tall and heavy (17.72 in, 25.13 lb): measure cabinet clearance and shelf space first.

The premium outsider: Typhur Dome 2

The Typhur Dome 2 ($299.95, read at Typhur.com on Oct 7, 2026) doesn’t belong to either camp, and it’s the honest reference point for what more money buys. Its 5.6-qt dome fits a 12″ pizza, it heats from the top and bottom (neither brand above publishes dual-element heating), and it’s the only fryer here with a manufacturer-published noise figure: 51 dB. The trade-offs are a wide 19.7-inch footprint, a price more than three times the TurboBlaze’s for similar basket volume, and a warranty term that wasn’t published on the page we read — check it before buying. Buy it for the published quiet figure and the dual heat, not for capacity.

Verdicts by case

Small kitchen: the Cosori Lite. At 9 lb with the smallest footprint among our fully verified picks, it’s the one that lives in a cupboard between uses — and you keep the 2-year warranty and app control. If counter depth rather than storage is your constraint, the AF141’s 10.55-inch depth is the slimmest single-basket option here.

Family of 3–5, one basket: the Cosori TurboBlaze. Six quarts, 1,725 W, the 90–450°F range, two years of warranty, and the lowest verified price in this comparison ($89.99). On published specs per dollar, it’s the fryer to beat.

Budget buy: the TurboBlaze again — it’s simply the cheapest verified pick here. The AF141 ties the Lite at $99.99 and makes sense instead if you want maximum wattage and no app account; just note the 1-year warranty and recheck stock.

Two dishes at once: the Ninja DoubleStack XL, unopposed. Two 5-qt baskets, 10 qt total, in a footprint narrower than any side-by-side dual. Budget for the height (17.72 in) and the 1-year warranty.

Quiet or low-profile premium: the Typhur Dome 2 — the only published 51 dB figure and a 10.3-inch-tall dome that slides under cabinets taller fryers can’t.

How we compared

Manufacturer spec sheets and official manuals first, retailer listings second, never another review site’s numbers. Every price was read on a live page on Oct 7, 2026 and is stamped with its store above; Amazon prices move independently of the brand-store reads, so re-check at checkout.
