I just want to make a contribution in moving all the way up to the Cadillac of convenience cookers. I have the 6qt Ninja Foodi pressure cooker. It does air frying, broiling, sautéing, slow cooking, pressure cooking, steaming, and baking. I purchased a special made grill for broiling too. So it leaves grill marks on steaks when I grill them. It's a power hog. Although it's rated at 1800 watts AC 110, it tests out at around 1300 watts on average for things like broiling and air frying. On pressure cook settings it runs around 1100 watts. So you need a few top rated batteries and lots of solar.
I use it about 30 minutes for steaks, 10 minutes to preheat the grill and 20 at most to broil. It takes 30 minutes to go from the freezer with frozen chicken wings to the very best restaurant quality chicken wings on the plate. All this takes place in one pot. It's just knowing how. I can make a huge batch of chili in the single pot and use the sautéing feature to rewarm leftovers from the fridge. It makes perfect French Fries from frozen in around 17 minutes. It will pressure cook a full roast in 40 minutes. You can have leftovers for pulled beef or pork tacos, pulled pork barbeque sandwiches etc... It's convenient too. You slide the pot out and wash all the dishes in that same pot. Then you rinse out the pot and you are done.
Most recipes I just set it and forget it. It shuts itself off when its supposed to.
