I have only had my Delta 2 about a week, but it has already been a game changer for me. It has become central to my quality of life. With 1800w of AC output in such a small and complete package I now can move more freely while maintaining my ability control my environment. I have severe food allergies and the Delta 2 allows me to take my food preparation on the road with me so that I can insure my food is allergen free and cooked to my preference. No more cold, water logged food on the go. I now have a small refrigerator, induction burner, and water pot in the trunk of my car, or in my SUV. I can pull over at the time and location of my choice and by doing so level out the nutritional intake that curbs the peaks and valleys associated with delayed meals. The Delta 2 is easy to use, has ample charging options, and is rock solid in its performance. Game changer and life changer.
