Ordered a Black and Decker unit and it works marvelously. It’s a bit smaller than I want but it doesn’t piss of the multiplus and it cooks FASTER. French Fries in 6 minutes instead of 15. Not sure what Ninja is doing but I will be avoiding their brand from now on. I sent them the same video and they are saying I have to send the unit to them to test, but unless they have a victron, it’s not going to happen, this oven works fine on wall power because the grid doesn’t care about the PF of one little air fryer.
I still think this is a shared problem but with the Black and Decker is onboard, I have one less thing to worry about. B&D could learn a bit about UI from Ninja, but at least the engineering part of their product is solid.
