The Ninja Foodi Possible Cooker Pro has many features including braise, slow cook high and low, proof, steam, keep warm, steam, sear/sauté, sous vide, and bake. All of these functions can be found on other multi-function appliances but the question is, do these functions work the same in all machines.
I spent several days testing the temperature of the functions in the Ninja Foodi Possible Cooker Pro and have compared them to the temperatures of some of the same functions in my Crockpot.

This recipe was made using the Ninja® Foodi® PossibleCooker™ PRO. Any slow cooker can be used for this recipe.
One of the most commonly asked questions about the Ninja Foodi Possible Cooker Pro is how does it compare to other cookers and can recipes for other cookers be used in the Ninja Foodi Possible Cooker Pro and achieve the same results. Many of these questions are specific to the slow cook function.
Well, instead of guessing and having my recipes not turn out as expected, I started experimenting! I tested out the slow cook low and hi, braise, keep warm, sous vide, sear/sauté high and low, proof, bake, and steam functions on the Ninja Foodi Possible Cooker Pro.
Something to keep in mind is that all of these tests were done on water. Water does not cook at the same temperature as food. Water boils at 212 degrees Fahrenheit so you will not see any temperature measurements higher than 212 degrees. These tests were done to see how the Possible Cooker compares to the Crockpot and to check to see how quickly the temperature changes based on the different settings.
For the testing, I added approximately 18 cups of room temperature water to the 1200 Watt Ninja Foodi Possible Cooker Pro (up to the sous vide line inside the pot) and the same amount of water to the crockpot. All of the experiments started with the same amount of room temperature water in a room temperature pot. The temperature of the water was taken with an instant read thermometer.

Slow Cook Low
I tested the slow cook low function every five minutes in the Possible Cooker Pro and in the Crockpot. The Possible Cooker Pro was much quicker to heat up than the Crockpot. It took almost 3 hours for the Crockpot to catch up the Possible Cooker. After 3 hours of cook time, the temperatures were pretty close, with the Crockpot ending the 8 hour slow cook time a few degrees warmer than the Ninja Foodi Possible Cooker Pro.

Slow Cook High
I tested the slow cook high function every five minutes in the Possible Cooker Pro and in the Crockpot. The Ninja Foodi Possible Cooker Pro started out much warmer than the Crockpot and I wasn’t even sure if the Crockpot was going to get up to the same temperature as the Possible Cooker. It took almost 2 hours for the Crockpot to reach the same temperature as the Possible Cooker. The slow cook high function is very similar to the braise function on the Ninja Foodi Possible Cooker Pro.
Based on the very small differences in temperatures, I would expect the results to be very similar for the slow cook high and braise on the Possible Cooker. However, the Crockpot does not reach the max temp until about the 2 hour mark. This means that the Crockpot will cook slower than the Ninja Possible Cooker on slow cook high or on braise. I would recommend increasing the cook time in the Crockpot if you are going to use it. I have not experimented with comparing cook times for proteins in the Ninja Foodi Possible Cooker Pro and the Crockpot yet, but will update the post once I have a good idea of how much longer the Crockpot will take.

Bake
There is no comparison between the Ninja Foodi Possible Cooker Pro and the Crockpot because the Crockpot does not have the bake function. During the bake function, it takes roughly 35 minutes for the water to boil.

Braise
There is no comparison between the Ninja Foodi Possible Cooker Pro and the Crockpot because the Crockpot does not have the braise function. The braise function is VERY similar to the slow cooker high function. Both reached max temp at around the one hour mark. The braise function is a few degrees (about 5) lower than the slow cook on high in the Ninja Foodi Possible Cooker Pro for the first hour. But, they are so similar that I would expect to have very similar results using the braise and slow cook high in the Possible Cooker.

Keep Warm
The keep warm function are very similar between the Ninja Possible Cooker and the Crockpot. You should have similar results with both machines.

Steam
There is no comparison between the Ninja Foodi Possible Cooker Pro and the Crockpot because the Crockpot does not have the steam function. The Possible Cooker does need to pre-heat for several minutes before adding food. I was surprised to see that the Possible Cooker got up to 187 degrees Fahrenheit quite quickly! And, it stayed at the same temp for about 20 minutes and then the temperature started to decline. The steam function only lasts for 1 hour-but you should not need to steam anything for longer than an hour. If you do, then I would recommend using a different function.

Sous Vide
There is no comparison between the Ninja Foodi Possible Cooker Pro and the Crockpot because the Crockpot does not have the sous vide function. The interesting thing about the sous vide function was that there is a preheat time, and then once it gets up to temperature the machine beeps and tells you to add food. However, the temperature of the water is not actually at the desired temperature. It took almost 20 minutes AFTER the machine said to add food for the water to actually reach the desired temperature. Be sure to measure the temperature of the water BEFORE adding the food to make sure the temperature is correct. Once the temperature reached 165 degrees, it pretty much stayed there for the remainder of the 8 hour testing time.

Sear/Sauté
There is no comparison between the Ninja Foodi Possible Cooker Pro and the Crockpot because the Crockpot does not have the sear/sauté function. There isn’t a huge difference in the temperature between the sear/sauté low and high setting on the Ninja Possible Cooker Pro. On average, the high setting is about 10 degrees warmer than the low setting, until you have been using the function for about 30 minutes. After 30 minutes, the temperature is about the same for both the high and low setting. Both the high and low settings take about 35 minutes to reach max temp of 212 degrees. However, when you are searing food instead of water, you will notice that the high setting does seem to cook much hotter and faster than the low setting, even if that doesn’t 100% translate to the water test.

Proof
There is no comparison between the Ninja Foodi Possible Cooker Pro and the Crockpot because the Crockpot does not have the proof function. Proof has the lowest temperature option out of all of the functions on the Ninja Possible Cooker Pro. It took about 35 minutes for the water to get up to 100 degrees but once it got there it stayed there pretty consistently.
