One-line verdict
A portable air fryer with proper glass containers and storage lids is brilliantly civilised, provided 3.8L is enough food for your particular domestic circus.
Best for
Small households and lunch-preppers who want to cook in glass containers, store the leftovers, then give them a less mournful second outing.
Skip it if
Skip it if you regularly need to cook beyond a 3.8L container’s capacity or dislike managing an adaptor as part of dinner.
The full picture
Air fryers have become the kitchen equivalent of a flat-pack ottoman: everyone has one, nobody quite remembers where it is meant to live, and leftovers still end up in a random plastic box with a missing lid. The Ninja CRISPi FN101UKSG attempts to tidy up that particularly modern bit of domestic nonsense by making its cooking vessels glass containers that also come with storage lids.
The set includes a 1.4L container for smaller jobs and a 3.8L container for the more ambitious version of dinner, plus two non-stick crisper plates. Above them sits Ninja’s 1,700W PowerPod, which provides Air Fry, Roast, ReCrisp and Keep Warm functions. The point is not culinary wizardry; it is a more coherent route from cooking to storing than decanting everything into the Tupperware drawer of broken promises.
We think that makes it one of the more persuasive compact-air-fryer concepts. The glass containers are borosilicate glass with BPA-free plastic handles, while the crisper plates have a PFAS- and PTFE-free nano-ceramic coating. Ninja describes the containers as designed for non-toxic cooking and storing, which is refreshingly specific in a category often content to shout “crispy” until everyone gives up asking questions.
There is a little ceremony involved. The larger 3.8L container requires the supplied adaptor, while the adaptor must not be used with the 1.4L container. Still, this is a clear choice for people whose kitchen ambition is not a banquet, but a decent hot meal and leftovers that do not emerge from the fridge looking like an apology.
The Irresistible
- The useful idea is the container system: one 1.4L and one 3.8L glass vessel, each with a storage lid, so cooking and putting food away can happen without an extra round of pot archaeology.
- Four functions—Air Fry, Roast, ReCrisp and Keep Warm—make the PowerPod more considered than a one-trick crisping machine.
- The borosilicate glass containers, BPA-free handles and PFAS- and PTFE-free crisper-plate coating give the materials story some welcome substance.
The Clever Part
- Two non-stick crisper plates are included, one for each CleanCrisp container.
- The 1,700W PowerPod has a UK plug and is rated at 240V and 8A, so the UK FN101UKSG specification is properly stated rather than left to international-listing roulette.
- The containers are dishwasher-safe, which matters because a clever leftover system becomes considerably less clever when it creates a sink-side tribunal.
- A two-year guarantee is included.
The Fine Print
- Cooking with the 3.8L container requires the PowerPod adaptor; the same adaptor must not be used with the 1.4L container, so the setup has one rule to remember.
- Its listed dimensions are 34.5cm high, 30.4cm wide and 34cm deep; portable does not mean it vanishes into a drawer between toast and regret.
The Reality Check
- The largest supplied container is 3.8L, so this is a poor fit for households routinely cooking large quantities in one go.
Buyer questions answered
How much food can the Ninja CRISPi 3.8L air fryer cook?
The Ninja CRISPi FN101UKSG includes a 3.8L glass container, alongside a smaller 1.4L container. That gives it two genuinely distinct formats rather than asking one bowl to audition for every meal.
What can the Ninja CRISPi air fryer do besides air frying?
It has Roast, ReCrisp and Keep Warm functions as well as Air Fry. ReCrisp is the useful little extra for food that has spent too long becoming psychologically attached to the fridge.
Does the Ninja CRISPi 3.8L container need the adaptor?
Yes, the adaptor should be used when cooking with the 3.8L container and must not be used with the 1.4L container. A small rule, but one worth knowing before supper becomes an instruction-manual event.
