Can these types of charcoal burners work with CO methods?

I think those are for "coconut" charcoal, not "regular" charcoal. And they seem small, like they wouldn't hold enough, so you'd need several. I don't think I'd use them for lump charcoal, which is what's recommended for CO. I'll stick to just lighting the "regular" charcoal in the conventional way. I don't want to reinvent the wheel.

Okay, so for this method, in plain English, I take these charcoal, burn them on this grill, wait for smoke to clear, and take grill into enclosed airtight space? Will these products work?
