I hear what you're saying. I went to Nepal and was very concerned about the food, water and my unadventurous diet preferences.
Staying in guest houses there were no microwaves, no irons (and no heat). I took lots of dried soups and ramen and this electric pot. I also had a converter that made it okay for 220v, but see they now have a dual voltage model. The pot is small with a wide mouth and, can be stuffed with other items when packing. There was plenty of agreeable and safe food, and we used an ultraviolet light to sterilize drinking water so I never used the pot but was glad to have it.
