I bought Yamaha clean generator when I purchased my FEC. It runs the laptop but gives the cooker fits. I switched to a deep cycle marine battery with a sine inverter last year and it works perfect. Cookshack gave me several controllers to try to see if that was the issue but they all did the same thing. It is not an IQ by the way, just the old Traeger controller.
FEC 100--Sold and sorely missed.
