Ninja and Tower are two of the most recognisable air fryer names on Amazon UK, but these two models sit at opposite ends of the shelf. The Ninja Foodi MAX Dual Zone AF400UK is a large 9.5L twin-drawer machine built for families: two independent 4.75L zones that cook at different temperatures and finish together, plus six functions including roast and dehydrate. The Tower T17023 Vortx is a tiny 2L single-basket fryer designed for one person, a small kitchen and the lowest possible price. One is a versatile batch-cooking centrepiece; the other is a compact everyday helper. This comparison breaks down the specs, the trade-offs and which one genuinely suits your kitchen, so you can choose the right air fryer with confidence.

Our Verdict

The Ninja Foodi MAX Dual Zone AF400UK and the Tower Vortx 2L are not really rivals — they suit very different buyers. The Ninja is the better air fryer for families and anyone who wants versatility: 9.5L across two independent 4.75L zones, a digital touchscreen and Sync Finish so a main and a side are ready together. The Tower is the pick for a single person, a very small kitchen or the tightest budget — 2L is enough for one, and its compact size and low price are the whole point. Choose the Ninja for capacity and features; choose the Tower if you cook for one and want the cheapest, smallest option.

Our process

How we choose our picks

We don’t lab-test products ourselves. Instead we synthesise the strongest independent evidence — current Amazon UK listings, verified-buyer feedback, published specs and UK pricing — into clear, honest recommendations. We earn a commission if you buy through our links, but that never changes which products we rank.

  • Current UK availability

    We only shortlist products actively listed and in stock on Amazon UK, checked against live catalogue data — not last year’s models.

  • Publicly visible buyer feedback

    We look at how each product is received by UK shoppers — its overall rating standing and the praise or complaints that recur in public reviews — rather than relying on a single reviewer’s opinion.

  • Published specs & value

    We compare manufacturer specifications, typical UK price bands, warranty and running costs so each pick is right for a real budget and use-case.

  • UK-specific fit

    We factor in UK voltage, plug/fitting standards, CE/UKCA marking and Consumer Rights Act cover — details that generic global lists miss.

More about our standards on the About page.

Buying Guide

  • 1Match capacity to household size — the Ninja's 9.5L splits across two 4.75L drawers and feeds a family in one batch, while the Tower's 2L basket realistically suits one person only.
  • 2Decide if you need dual-zone cooking — the Ninja can run a main and a side at different temperatures and finish them together with Sync Finish, whereas a single 2L basket means cooking one thing at a time.
  • 3Measure your worktop — the Ninja is a large twin-drawer unit around 42cm wide that needs a dedicated spot, while the Tower's compact footprint tucks into the smallest kitchens.
  • 4Weigh the controls — the Ninja's digital touchscreen gives precise time and temperature across six functions, while the Tower keeps costs down with a simple manual dial and a 30-minute timer with auto shut-off.
  • 5Set your budget — the Ninja sits at the premium end around £150–£180, while the Tower is a budget buy; if the lowest price matters most, the compact Tower wins on cost.
  • 6Think about cleaning — the Tower's single 2L non-stick basket is quick to wash and lift out, while the Ninja gives you two larger drawers to clean after a big cook.

Editor's Note

These two barely compete — they solve different problems. The Ninja Foodi MAX Dual Zone earns its size if you cook for a family or want a main and a side ready together; its 9.5L twin drawers and Sync Finish do things no 2L fryer can. The Tower Vortx makes sense only if you cook for one and want the smallest, cheapest option on the shelf.

Our Take

Cooking for one in a tiny kitchen on a tight budget? The Tower Vortx 2L is all you need. For families, batch cooking or two-food-at-once versatility, the Ninja Foodi MAX Dual Zone is worth the extra space and spend.

Questions & answers

Frequently asked questions

Is the Ninja or Tower air fryer better?
It depends on who you are cooking for. The Ninja Foodi MAX Dual Zone is better for families and anyone who wants to cook two foods at once, with 9.5L across two independent 4.75L zones and a digital touchscreen. The Tower Vortx 2L is better for one person, a very small kitchen or the tightest budget — it is far more compact and cheaper, but its single 2L basket only realistically serves one.
What is the difference between Ninja and Tower air fryers?
These two models are worlds apart. The Ninja Foodi MAX Dual Zone AF400UK is a large 9.5L twin-drawer fryer (2 x 4.75L) with a digital touchscreen, 2470W and six functions including roast and dehydrate. The Tower T17023 Vortx is a compact 2L single-basket fryer with a manual dial, 1000W and a 30-minute timer. The Ninja suits families and batch cooking; the Tower suits one-person meals in a small kitchen.
Is a 2L air fryer big enough?
A 2L air fryer like the Tower Vortx is best for one person and single portions — chips, a couple of pieces of chicken or a small batch of veg. It is too small for a family or for cooking a main and a side together. If you regularly cook for two or more, step up to a larger model such as the Ninja Foodi MAX Dual Zone's 9.5L.
Does the Tower air fryer have dual zones like the Ninja?
No — the Tower T17023 Vortx is a single 2L basket, so it cooks one food at a time. Dual-zone cooking is the Ninja Foodi MAX Dual Zone's headline feature: two independent 4.75L drawers that can run at different temperatures and finish together with Sync Finish. If cooking two things at once matters to you, the Ninja is the one to choose.
