At first when I was considering this thing, I thought the heat source was singular as well. But, it also carries a large heating element in lid. So it does use fully heated convection so in some ways quite similar to a regular pellet grill.
Not sure how Ninja engineers work their magic but they build some darn good appliances. I.E., many are now raving about Ninja's new all in one coffee maker. Glowing about how such an appliance can do it all (espresso, pourover, drip, styles). Not necessarily my cup o' tea, but, they seem to pull rabbits outta their hats for everything they touch.
In any case plan is to give it a whirl tonight. I have a whole tenderloin I'm gonna cut some steaks from if the youngest, her partner and the kids all come over. If not the plan is I may do a piece of pork belly I have in the freezer (I get from Costco). They sell cleaned PB that is "sliced" about 2" thick. So I enjoy slapping one of those on the pellet grill letting it smoke for a while then cranking the heat up to about 375-400 and letting it get "crispy".
But, BFletch's results speak volumes as do every other test I've read and viewed on YT. So, I have high hopes.
I know it likely will not work as my pellet smokers do, but from what I've seen it does darn close. Stay tuned, keep the popcorn buckets filled.
My biggest challenge right now is managing to keep it close enough to a 20 amp outlet (as it does draw about 17-18 amps), (I bought a suitable 12ga extension cord at Menards yesterday), and I have a 30amp breaker line in the garage.
Once weather gets better I am going to install a 20amp outlet on my deck.
My other challenge is the thing is a bit too large for what I thought would be a good folding table for it. It sort of fits it but, the feet hang over the front and rear edge. I'm hoping not to have to invest in the Ninja stand. Close to $200 just for that! I did also order a cover for it. I'll post up some photos in a bit. Once I get outside
