Air fryers have transformed the way I cook—fast, clean, and impressively crispy. But when I recently tested two of the latest portable glass air fryers—the Ninja Crispi and the Kismile Portable Air Fryer—I realized not all compact models are created equal. Both promise nontoxic cooking, easy cleanup, and portability, but the way they perform day-to-day tells a very different story.
In this detailed comparison, I’ll walk you through the key differences, my hands-on experience, and which model I’d actually recommend depending on your needs.
Key Difference at a Glance: Ninja Crispi vs Kismile Portable Air Fryer
The Ninja Crispi Portable Glass Air Fryer feels more like a mini powerhouse—offering a 4-in-1 system with glass containers and the unique Crispi PowerPod that delivers the punch of a full-size air fryer. On the other hand, the Kismile Portable Air Fryer focuses on simplicity and automation with 5 preset modes, a more compact dual-bowl setup, and effortless usability.
In short:
- Ninja Crispi = power, flexibility, and meal variety.
- Kismile = simplicity, presets, and travel convenience.
- ALL-IN-ONE SYSTEM: Includes the Ninja Crispi PowerPod, 4-qt and 6-cup CleanCrisp glass containers, and 2 storage lids

Detailed Comparative Review – Design and Build Quality
Right out of the box, both models impressed me, but in different ways.
The Ninja Crispi looks and feels premium—sleek Cyberspace Gray finish, sturdy glass containers, and that satisfying weight that hints at durability. It’s a bit larger, yes, but it doesn’t feel bulky thanks to its well-thought-out design. The CleanCrisp glass containers are truly a standout—crystal clear, non-toxic, and built to last.
The Kismile Portable Air Fryer, in contrast, is smaller, lighter, and designed for portability. Its dual-glass bowls stack perfectly, and the non-slip feet make it safe to use even in a cramped RV kitchen or dorm. However, the glass feels thinner compared to Ninja’s, and while still durable, it gives off a more “compact appliance” vibe than a full-fledged cooking system.
Winner (Design): Ninja Crispi – more robust, professional-grade feel.
- ALL-IN-ONE SYSTEM: Includes the Ninja Crispi PowerPod, 4-qt and 6-cup CleanCrisp glass containers, and 2 storage lids

Ease of Use and Setup
When it comes to everyday use, Kismile wins for convenience.
You literally plug it in, choose one of the 5 presets, and let it handle the rest. Whether I roasted vegetables, reheated fries, or broiled fish, the presets were spot-on for timing and temperature. There’s no need to fiddle with manual settings—perfect for people who want quick, foolproof results.
The Ninja Crispi, on the other hand, offers more flexibility but requires a little more attention. You’ll need to select functions, set temperatures, and sometimes switch between containers using the Crispi Container Adapter. Once you get used to it, though, the control it gives is rewarding. I particularly liked the Recrisp mode, which revived soggy leftovers to near-restaurant quality.
Winner (Ease of Use): Kismile – effortless and intuitive.

Performance and Cooking Results
Now, this is where things get interesting.
The Ninja Crispi outperformed the Kismile in raw power and versatility. The Crispi PowerPod really does pack a punch—it evenly crisps chicken wings, bakes small batches of muffins, and handles full meals like a 4-lb chicken with veggies beautifully. The air circulation felt stronger and more consistent, giving that signature “Ninja crisp” texture that’s hard to beat.
The Kismile Portable Air Fryer still produces excellent results, but it’s better suited for smaller portions or simpler recipes. The Deep Roast mode worked wonders for frozen snacks, and the Broil mode added a nice sear to steaks. However, when I tried larger items like whole chicken or layered dishes, the heat distribution wasn’t quite as even.
Winner (Performance): Ninja Crispi – superior airflow and even cooking.

Functionality and Cooking Modes
While the Kismile offers one extra mode on paper (5-in-1 vs. Ninja’s 4-in-1), the Ninja’s modes feel more dynamic.
The Max Crisp setting delivers incredible texture without drying out the food, and the Bake function doubles as a mini oven replacement. The Recrisp feature alone makes it worth it if you often reheat fries or leftovers.
The Kismile presets, though simpler, cater to convenience. The Keep Warm function is a small but thoughtful touch—ideal for family dinners where not everyone eats right away.
Winner (Functions): Tie – Ninja for versatility, Kismile for simplicity.
Cleanup and Maintenance
Both air fryers make cleanup painless.
All glass parts and lids are dishwasher-safe, and there’s no greasy residue sticking to plastic or coated baskets like in traditional air fryers. I did notice, though, that the Ninja’s containers are heavier and take up more dishwasher space, while the Kismile bowls fit neatly and clean faster due to their compact size.
Winner (Cleanup): Kismile – faster and easier for small kitchens.

Portability and Storage
If you’re short on space or travel often, Kismile takes the crown. Its nested bowl design makes it easy to store, and the whole unit is lighter. I even carried it along for a weekend cabin trip—it fit in the car trunk perfectly.
The Ninja Crispi, while “portable” in name, feels more like a countertop appliance you’d keep in one place. It’s still more compact than a full-size fryer, but not something I’d pack up often.
Winner (Portability): Kismile – compact and genuinely travel-friendly.

My Verdict and Recommendation:
After weeks of testing both, I found that the choice depends on your lifestyle.
If you cook larger meals, love experimenting, and want full control over temperature and texture, the Ninja Crispi Portable Glass Air Fryer is worth every penny. It performs like a professional-grade appliance but still fits neatly on your countertop.
However, if you’re someone who values convenience, portability, and quick cleanup, the Kismile Portable Glass Air Fryer is the smarter buy. It’s compact, efficient, and ideal for solo cooks, couples, or those who travel often.
My Recommendation:
For power users and home cooks – Go for the Ninja Crispi.
For small kitchens, dorms, or travelers – Pick the Kismile Portable.
Both models are excellent in their own right, but the Ninja Crispi wins for performance, while Kismile triumphs in ease and practicality. Whichever you choose, 2025 is the year glass air fryers officially make plastic-coated baskets feel outdated.
