Honestly if you manage to fill the chip tray with ash when running a MES for a single cook my hat is off to you sir.
I use the
AMNPS or wood chips, depending on what I feel like doing. But you need not worry about emptying the wood chips any time soon during a smoke. Run one and add wood chips every 45 mins, you'll notice at the end, there's about still nothing in there. It does a very good job of atomizing the wood like it is meant to. It burns it to a fine ash.
Still with an electric, if you don't want to babysit, get an
AMNPS. Personally I still notice a huge difference in one way; the
AMNPS pellets never smell as good as wood chips.
