If you are either already experienced with some basic html and javascript or willing to learn some, reveal.js is my goto for things outside of work (really need to stick to the presentation file/application that is standard at the company in those settings). The creator also has slides.com, but you'll have to pay to get much use out of it (free edition limits to 5 presentations and they are all publicly viewable/searchable and can have ads added to them).
