Hi, I’m Ethan Walker, and I created Generator Savvy to make generator topics easier to understand without all the fluff. I’ve always been the kind of person who researches gear before buying it, especially when it comes to backup power, camping equipment, RV setups, and home preparedness. Over the years, I found that generator advice online was often either too technical or too vague. That pushed me to start writing clear, practical content that helps everyday people compare options, understand how different generators work, and make smarter buying decisions. At Generator Savvy, I focus on real-world questions about portable generators, inverter models, dual fuel options, camping use, RV compatibility, fuel choices, and backup power planning. My goal is simple. I want this site to be a useful place for people who want straight answers before they spend money or depend on a generator when it matters most.
