⚡ The short answer
These are the same air fryer at two sizes. Get the AF101 (4-qt) if you cook for one or two and want the smallest footprint and lowest price.
Get the AF150 (5.5-qt) if you cook for three or more, want to fit a whole small chicken, or prefer its roomier basket — it costs a little more for the extra capacity.
The 30-second version
The Ninja AF101 and AF150 share the same core design, the same simple controls, and the same reliably crispy results Ninja is known for. The decision between them is almost entirely about capacity vs. counter space vs. price — not cooking quality. The AF101 is the compact 4-quart best-seller; the AF150 is the larger 5.5-quart version for a few dollars more. Below is exactly how they differ.

Which one should you buy?
Buy the AF101 if…
You cook mostly for one or two people, counter space is tight, or you want the lowest price. It handles everyday portions — wings, fries, a couple of chicken breasts, roasted veg — without taking over your kitchen.
Buy the AF150 if…
You regularly cook for three or more, you like to batch-cook, or you have been frustrated by a 4-quart basket being too small for a whole chicken or a full side of vegetables. The extra 1.5 quarts is the difference between one batch and two, and it is usually only about $30–40 more.

Frequently Asked Questions
What is the difference between the Ninja AF101 and AF150?
The main difference is capacity: the AF101 has a 4-quart basket and the AF150 has a larger 5.5-quart basket. The AF150 also has slightly higher wattage and one extra cooking program, and it costs a bit more. Cooking performance and controls are essentially the same — both deliver the crispy results Ninja is known for.
Is the AF150 worth the extra money over the AF101?
If you cook for three or more people or want to fit a whole small chicken, yes — the extra 1.5 quarts is meaningful and the price difference is usually only about $30–40. If you cook for one or two, the AF101 is the better value and takes up less counter space.
Do the AF101 and AF150 cook differently?
No. Both use the same air-frying technology, the same 105–400°F temperature range, and the same style of easy-clean, dishwasher-safe basket. Cooking times and results are effectively identical for the same food — the AF150 just lets you cook more of it at once.
Can the Ninja AF101 fit a whole chicken?
A small whole chicken (around 3–4 lb) can fit in the AF101, but it is a tight squeeze and airflow suffers. If cooking whole chickens is a regular thing for you, the larger AF150 (or a 6-quart-plus model) is a better fit.
