Yes, the feeder works the same for both chips, chunks, or pellets. The screen hole size at bottom of feeder is small enough to hold pellets. Something you can't do with the AMNPS is a mod i did with the cold smoker. I modified it to accommodate a variable air pump at bottom where wood source burns. This mod with the variable air pump allows for burn rate control. I don't see how you could do this with a AMNPS. Your table issue would be difficult to accommodate the cold smoker without an additional table.
I'm just all for keeping it simple with no mods if I can get the results I want. If the AMNPS hadn't been invented I would have gone with MES Cold Smoker and would have made it work with both units on tables or a MES stand.
