What Is the Ninja Crispi?
The Ninja Crispi is a unique glass air fryer system that uses a removable PowerPod containing the heating element and controls. Instead of cooking in a traditional drawer basket, food is cooked inside transparent glass containers that can also be used for serving and storing meals.
The Crispi range was designed with portability and convenience in mind. The PowerPod can be attached to different-sized containers, making it easy to switch between cooking a single meal and preparing food for multiple people. Full specifications for the current range are listed on the official Ninja UK site.
What Is a Traditional Ninja Air Fryer?
Traditional Ninja Air Fryers use drawer-style baskets and are available in several formats:
- Single basket models
- Dual-zone air fryers
- FlexDrawer models
- Large family-sized air fryers
These appliances are designed primarily for everyday cooking and often include multiple cooking functions such as Air Fry, Roast, Bake, Reheat, Dehydrate, and Max Crisp. You can see how the leading models stack up in our round-up of the best air fryers UK.
Cooking Performance
Both appliances deliver the crispy results Ninja is known for.
The Ninja Crispi performs particularly well for smaller portions, leftovers, snacks, and meal-prepped dishes. The transparent glass design allows you to monitor food without opening the container.
Traditional Ninja Air Fryers generally offer more powerful cooking performance, larger cooking areas, and faster preparation of family-sized meals. Models such as the Ninja Foodi MAX Dual Zone AF400UK allow you to cook two different foods simultaneously using separate baskets. Whichever model you choose, the Food Standards Agency guidance on cooking food thoroughly is worth a read, particularly for chicken and other high-risk foods.

Capacity
Capacity is one of the biggest differences.
The original Ninja Crispi includes smaller glass containers designed for one to two people, while larger Crispi Pro models can handle family meals. However, most standard Ninja Air Fryers still offer significantly more cooking space.
For large families or batch cooking, traditional Ninja Air Fryers are usually the better option. If you are unsure how much space you actually need, our guide to what size air fryer you need walks through the maths.

Portability and Storage
This is where the Ninja Crispi shines.
The removable PowerPod and stackable glass containers take up less space than many conventional air fryers. The system can be packed away when not in use, making it ideal for small kitchens, flats, caravans, and holiday homes.
Traditional air fryers are bulkier and typically remain on the kitchen worktop.

Cleaning
The Ninja Crispi uses dishwasher-safe glass containers, allowing you to see exactly how clean they are after cooking. Many users also appreciate cooking without traditional non-stick baskets.
Traditional Ninja Air Fryers are generally easy to clean too, but larger baskets can take up more dishwasher space.

Features
The latest Ninja Crispi Pro models include up to seven cooking functions and temperatures up to 230°C.
However, premium Ninja Air Fryers still offer the widest range of features, including:
- Dual-zone cooking
- Smart Finish
- Match Cook
- Larger capacities
- Multiple cooking modes
These features can make meal preparation easier for busy households. For independent lab testing on crisping and evenness across brands, the Which? air fryer reviews are a useful sense-check.

Value for Money
The Ninja Crispi is innovative and convenient, but its unique design comes at a premium price.
Traditional Ninja Air Fryers often provide larger capacities and more features for a similar or lower cost.
For most buyers, a standard Ninja Air Fryer offers better value. Running costs are broadly similar between the two, and both are far cheaper to run than a conventional oven — our air fryer running costs UK guide and our air fryer vs oven comparison break down the numbers.

Frequently Asked Questions
Is the Ninja Crispi better than a normal Ninja air fryer?
Not outright. The Ninja Crispi is better for portability, meal prep and cleaning thanks to its glass containers, but a traditional Ninja air fryer wins on capacity, cooking functions and value for money. For most UK households cooking family meals, a standard Ninja air fryer is the more practical buy.
Can you cook a full family meal in the Ninja Crispi?
The larger Crispi Pro containers can handle a family meal, but the standard Crispi containers are sized for one to two people. If you regularly cook for three or more, a dual-zone Ninja air fryer such as the Foodi MAX Dual Zone will save you batch cooking.
Are the Ninja Crispi glass containers dishwasher safe?
Yes. The glass containers and lids are dishwasher safe, which is one of the system’s biggest practical advantages. The PowerPod itself contains the heating element and electronics, so it should be wiped clean by hand rather than submerged.
Does the Ninja Crispi cost more to run than a normal air fryer?
No meaningful difference. Both draw broadly similar wattage and cook far faster than a conventional oven, so running costs work out at a few pence per meal. Our air fryer running costs guide has the full breakdown at current UK energy prices.
Which Ninja air fryer is best for a small kitchen?
If worktop space is genuinely tight, the Ninja Crispi is the best option because the PowerPod and containers can be stored away in a cupboard. If you can spare the space, a compact single-basket Ninja air fryer gives you more capacity for the money.
Final Verdict
The Ninja Crispi is one of the most innovative air fryers released in recent years. Its portable glass container system is perfect for smaller households, meal prep enthusiasts, and anyone looking for a more versatile cooking and storage solution.
However, for most UK households, a traditional Ninja Air Fryer remains the better buy. Larger capacities, more cooking functions, and better value for money make it the more practical choice for everyday cooking.
If convenience and portability are your priorities, choose the Ninja Crispi. If you want the best all-round air fryer experience, choose a traditional Ninja Air Fryer.
