If you’ve been searching for a space-saving, travel-ready air fryer that doesn’t compromise on performance, you’ve likely come across two popular contenders — the Ninja Crispi Portable Glass Air Fryer and the Kismile Portable Glass Air Fryer. Both have been making waves for their compact design, non-toxic glass bowls, and surprisingly versatile cooking functions. But when it comes down to everyday use, which one truly delivers a better experience?
After testing both models in my kitchen over a few weeks, I found that while they share several similarities — such as being compact, glass-based, and travel-friendly — their performance and usability differ in key ways that might sway your decision. Let’s break it all down.

Detailed Comparative Review

Design and Build Quality
The Ninja Crispi immediately stands out with its premium finish and sturdy glass containers. The TempWare glass gives it a solid, high-end feel, and I liked that it included two differently sized bowls — one for single meals and one for family portions. The heat-safe feet were a subtle but valuable feature — I could set it on my marble countertop without any worry.
The Kismile, however, impressed me with its sleek and compact body. It’s noticeably lighter and easier to move around — perfect for smaller spaces or even an RV kitchen setup. The glass bowls, while thinner, feel durable and the stacking design makes storage a breeze.
Verdict:
- Ninja Crispi feels more robust and premium.
- Kismile wins in terms of compactness and portability.
- ALL-IN-ONE SYSTEM: Includes the Ninja Crispi PowerPod, 4-qt and 6-cup CleanCrisp glass containers, and 2 storage lids

Ease of Use
This is where the Kismile Portable Air Fryer shines. The 5-in-1 pre-programmed settings make cooking foolproof — I could just press a button for “Roast” or “Broil” and let it do the rest. For busy mornings, that level of simplicity is a win.
The Ninja Crispi, on the other hand, gives you more manual control. You can tweak time and temperature precisely, which is perfect for those who like to fine-tune their recipes. The included Crispi PowerPod offers a handheld-style control system that feels futuristic, but it did take a bit of time to get used to.
Verdict:
- Kismile is better for convenience and beginners.
- Ninja Crispi caters to users who love custom control.
- ALL-IN-ONE SYSTEM: Includes the Ninja Crispi PowerPod, 4-qt and 6-cup CleanCrisp glass containers, and 2 storage lids

Performance and Cooking Results
The Ninja Crispi’s 1500W power paired with its Max Crisp mode delivered beautifully browned fries and crispy chicken in less than 10 minutes. The food tasted evenly cooked, and the air circulation felt strong and consistent.
The Kismile, while equally powerful on paper, took slightly longer for some recipes — particularly when using the larger bowl. That said, its Deep Roast mode was excellent for frozen snacks and reheating. Plus, the Broil function gave my vegetables a satisfying char that the Ninja slightly struggled to replicate.
Verdict:
- Ninja Crispi offers faster and more even cooking.
- Kismile gives more variety with its extra preset modes.

Cleaning and Maintenance
Both air fryers score highly here. Since they use glass containers, cleaning is quick and hassle-free. I simply popped them into the dishwasher, and they came out spotless.
However, Ninja’s snap-lock lids and overall build quality make cleanup and storage more organized. The nesting setup also means less clutter in your cabinets.
Verdict:
- Ninja Crispi has a slight edge for organization.
- Kismile is equally easy to wash and maintain.
- ALL-IN-ONE SYSTEM: Includes the Ninja Crispi PowerPod, 4-qt and 6-cup CleanCrisp glass containers, and 2 storage lids
-
Portability and Storage
If you travel often or have limited counter space, the Kismile clearly wins here. It’s lighter, smaller, and designed specifically for tight spaces like dorms or small apartments.
The Ninja Crispi, though portable, feels more like a full-size air fryer shrunk into a compact form. Its dual-container system means you can cook more but store slightly less efficiently.
Verdict:
- Kismile is the better choice for travelers or small kitchens.
- Ninja Crispi suits those who want more cooking capacity without going full-sized.
