If you’re considering an induction stove, as others say, the type of cookware is important. The pans need to be steel based, so some popular brands won’t work (Ridge Monkey for example). Also, some Camping pans such as the Outdoor Revolution and Outwell folding pans may not work as their steel bases deform when hot, and the base needs to be perfectly flat for induction to work.
We use a Campingaz Partygrill 400 for outdoor cooking, using the 907 bottle, of which we carry 2 including the one in the we van. So far we’ve had no issues getting refills, and one bottle does us for an entire season on camping with 90% outdoor use, and mostly using it to boil up pans etc.
However. I do get the point of using EHU if you have it, and we see other campers using George Foreman type grills more often these days.
