I have the original 6qt Instant Pot Vortex. The all stainless steel one, not the newer one with the window (which I haven't tried). My wife's household aides (who all have one of the many Ninja variants) LOVE it, as do I.
I have an IP Vortex 6-qt basket. About 5 years old I think. I use it for salmon, pork, beef, and especially chicken. I bought it specifically for chicken, and the good news is that it works for so many other things, as well. I use garlic salt on bone-in, skin on chicken thighs with the roast feature at 3:50° for 25 minutes. I throw in a couple of small red skin potatoes with the chicken, and if I’m having a root vegetable, I throw those in as well. I do not turn or flip the meat. The air fryer is a convection oven with good airflow and the meat gets cooked. If I’m doing asparagus or summer squash, I prep them while the chicken cooks and then those cook in the five to ten minutes while the chicken rests before eating. Brussel sprouts I time a little differently. For salmon, mahi-mahi, swordfish, etc. I also use the roast function and may (or may not) flip the meat during the cooking process. I have done pork loin and tenderloin in the air fryer, but have discovered that I prefer pork bites more than just the loin, or tenderloin. I use a smoked salt on the meat about an hour before cooking. I cook the bites in a mesh basket, spray them with a little bit of oil before cooking. I use the air fryer setting. I do something similar for steak bites . This is purely my preference. I have cooked sausage and peppers in the air fryer with excellent results. The sausage isn’t the healthiest of choices, but I feel it’s offset by the peppers, onion, and garlic. I also use my air fryer for desserts. Using it as an oven. Mine has a “bake“ feature. I mix up a batch of cookie dough, I have a small 4 1/2 inch cast-iron cookie skillet. I bake one cookie at a time which allows me portion control. It is a large cookie. I have also used my air fryer to make fruit, crisp, bread, pudding, pumpkin, custard, all in individual ramekins. I have pretty much not used my oven and barely my stove top since getting my air fryer and coupling that with my IP pressure cooker for soups, stews, chili, etc. I still use my stove top and my toaster. I use my microwave/convection oven for some things, but not as many as I used to.
Got a used Instant Pot Vortex 6 qt off of fb marketplace recently and I’ve used it daily ever since. I can’t attest for the other brands, but I love the simplicity of the buttons (even though there’s more than two) and the window/light feature is incredibly useful. Highly recommend the Instant Pot air fryer line
Instant Vortex 6 qt. I have cooked a whole chicken, wings, and they have come out delicious. They also excel at reheating frozen foods. A comment above also reminded me that my MIL was so excited to get an air fryer and she did not believe me that her CONVECTION OVEN already did the same thing 🙄She also doesn’t understand how the thanksgiving turkey gets done so much faster when I do it (I use the convection oven)
I'm in the same boat as OP. I had a Instapot Vortex 6 for a few years with a 3 prong plug and a couple weeks ago it got knocked off the top of the fridge where I stored it and it wouldn't work after it's unfortunate battle with gravity. My friend bought me a new one, same model and make, and it only had a 2 prong plug. This concerned me to the point I wasn't comfortable even plugging it in so we sent it back. Then she purchased another one from a large retailer which arrived with a 2 prong plug. I have a Ninja one coming in the next day or two but don't know if it has a 3 prong plug or not. Google says the 3 prong plugs arent necessary if the appliance is double insulated but my neighbor has been an electrician for over 30 years and I trust him. He says it's super dangerous to run such a high amp draw appliance without a dedicated ground plug
I got the instapot 6th vortex air fryer and it is great. It was that or the ninja crispy and at the time the instapot was on sale so I pulled the trigger on it.
