The ninja dual zone Air fryer has a huge 7.6 L total capacity. There is two individual baskets which are 3.8 L each. It has six programs, which are Air fry, roast, bake, dehydrate, Max crisp and reheat. If you are only going to use one of the baskets then zone one is the default zone to cook with, but what I particularly like about this is that for instance you can air fry at 200° in zone one for 30 minutes and you can roast in zone two at 180° for 20 minutes at the same time by pressing sync and then start. This will start zone one and when it reaches the 20 minute timer zone two will come off of hold and start roasting. If you remove the basket such as for chips to give them a shake, then the timer will pause until The basket is re-inserted and if both zones are cooking it will pause both timers. The other option that I really like which is nice and easy and can maximise your output if you’re cooking the same thing, For example if you had to Air fryer 1.5 kg of chips. Then place your chips in both baskets and on the zone one display enter in your temperature timer and press match then start. This will duplicate all of the information to zone two, Which makes it easy and super efficient. The max crisp is set at 240° and this is the only function that The temperature can’t be changed, and it could be set to a maximum time of 30 minutes. The air fryer function can be set between 150 and 210° and has a time range between 1 minute to 1 hour. The roast function allows you to use the ninja as a conventional oven which has a temperature range of 120 to 210° and has a timer that can be set from one minute to four hours. The reheat function has a temperature setting of 130 to 210° and can be set from 1Minute to One hour. The dehydrate function allows you to gently remove moisture from meat, vegetables and fruits. This temperature can be set between 40 to 90° and has a set time of up to 12 hours allowing you to create healthy snacks. The bake function means that you don’t have to wait the usual 10 to 15 minutes that your conventional oven would take to pre-heat Which is perfect if you just want to knock up a quick dessert. The temperature setting is 120 to 210° and has a time range between 1 minute to 4 hours. This ninja air fryer is super easy to clean, compare to my previous Tower Air fryer baskets. Overall we are very satisfied with our purchase as it has so many functions, Not just an air fryer. I hope you have found my review helpful.
