    How Big of a Generator to Run My 3500 RV AC and Appliances? Clear Guidance for Getting Started

    Ethan WalkerBy Ethan WalkerJune 30, 2026No Comments5 Mins Read

    To effectively run a 3500 BTU RV AC unit along with essential appliances, a generator with at least 3000 watts of starting power is recommended. This ensures that both the air conditioning and other devices can operate simultaneously without overloading the generator.

    Power Requirements for 3500 BTU RV AC

    Calculating the power requirements for your RV is critical for selecting the right generator. The starting wattage of your AC unit is typically higher than its running wattage. For a 3500 BTU air conditioner, expect the starting wattage to be around 2000 to 3000 watts, while the running wattage is about 1000 to 1500 watts.

    When considering other appliances, add their wattages to determine the total power requirement. Common appliances include:

    • Refrigerator: 600-800 watts

    • Microwave: 800-1200 watts

    • TV: 100-400 watts

    • Coffee Maker: 600-1200 watts

    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.
