We replaced the ineffective Gaganeau quartz unit with a 220vac two burner induction unit that was the same size so no need to cut anything. Simple to remove the wires from the old G unit and wire in the new unit. When parked dry camping without the generator, or on 120vac 30 amp shore power, we keep a portable unit in a kitchen drawer (look for one that fits the width and length of your drawers). That sits on top of the kitchen counter when needed. While using it off the inverter it draws 144 amps indicated on one of the Magnum inverters when on high. Boils water for French press coffee in about 5 minutes depending on altitude so consumes about 12 amp hours to make a pot of coffee. We also keep another one in a drawer in the outdoor entertainment center for use outdoors. So far, we have not seen much difference in performance or reliability brand to brand. All are far, far better than the old G unit.
