Ninja Foodi MAX Dual Zone 4kg Food Capacity Air Fryer vs CRISPi 4-in-1 Portable Glass Air Fryer — Comparison

The Ninja AF400UK Foodi MAX Dual Zone 4kg Food Capacity Air Fryer is listed at £179 and sits as the large-capacity, dual-zone family air fryer in this comparison. The Ninja CRISPi 4-in-1 Portable Glass Air Fryer - FN101UKGY is also £179, but it sits in a very different portable glass-container line. With the same price, the choice is between maximum cooking volume and drawer convenience versus a smaller prep-cook-serve-store system.

AF400UK offers 4kg food capacity, 9.5l capacity in litres, Auto-Adjust Fan, 6 functions and dishwasher safe parts. FN101UKGY uses a 1700W Power Pod with two TempWare glass containers, 4-in-1 portable cooking, multiple functions, little-to-no-oil cooking and 1.4L or 3.8L container capacity. The AF400UK is much bigger and built for two-zone meals, while the CRISPi is more modular, portable and storage-friendly. The CRISPi supplies a wattage figure; the AF400UK data focuses on capacity and functions.

Choose AF400UK if you cook for a family, want mains and sides at the same time, or need enough space for larger portions without juggling batches. It suits meal prep, frozen foods and busy dinners. Choose FN101UKGY if you cook smaller portions, value glass containers and like moving food from prep to cooking, serving and storage with less dish swapping. It is better for compact kitchens, leftovers, lunches and buyers who do not need 9.5l of air frying space. Also consider worktop depth, basket shape, cleaning routine, portion size and whether you usually cook one large batch or two separate foods, because those habits decide whether capacity, timing aids, presets or portability feels more valuable in daily use.

Bottom line: "choose AF400UK if 4kg food capacity and 9.5l dual-zone cooking matter most / opt for FN101UKGY if a 1700W portable glass CRISPi system with 1.4L or 3.8L containers suits smaller meals."
