1. How to Evaluate Your Camper’s Power Infrastructure?

Most campers and RVs are equipped with electrical systems that have specific power limits that need to be considered when selecting a generator. Many smaller to mid-sized campers typically come with a 30 amp electrical hookup inlet, which is the standard receptacle used to connect to an external 30 amp, 120-volt AC power source. Larger motorhomes may have 50 amp hookups, giving them the ability to draw more power for more substantial loads.

Inside the camper, whether it’s a 30 or 50 amp capacity, the appliances and devices run on standard 120-volt current, similar to houses and buildings. Two key dedicated circuits are pre-wired internally for the high-draw air conditioning unit and the microwave oven. When figuring out what size generator you need, you must know your inlet plug configuration, which devices need to be used simultaneously, and basic voltage requirements. This information will dictate the rated wattage of the power generator selected to safely power the complete electrical inventory inside your RV or trailer.

2. How to Calculate Total Electrical Power Demand?

The best way to figure out what size generator you need is to make a comprehensive list of all the appliances, electronics, lighting, motors, and other items you want to run while you’re camped off-grid. This will give you a basis for adding up the maximum rated wattage of each component to estimate the total anticipated power draw. Nameplates on devices list operating voltages and rated load, typically in watts or amps.

While individual small items may draw limited watts, operating multiple systems simultaneously can add up quickly. If you are running a 1500-watt air conditioner, 1200-watt microwave, and 1000-watt coffee maker at the same time, you would need at least a 3700-watt generator. Scaling upwards, motorhomes have the capacity for much higher loads like multiple ACs, large refrigerators, and outlets powering numerous gadgets. Properly determining the realistically expected peak demand prevents issues like tripping breakers, damaging equipment, or inadequate runtimes from an undersized generator.

According to research from the U.S. Department of Energy in 2023, accurately assessing peak demand can prevent up to 30% of electrical system failures in RVs, ensuring a safer and more enjoyable travel experience.

3. Why Are Startup Power Spikes Important?

When devices are first turned on, they need double or more of their listed running wattage ratings to start internal motors and compressors. Microwaves, fridges, and pumps may have these momentary peak power draws. Large AC units are the most impactful and need potent jolts of electricity to ignite, demanding as much as 15,000 watts at the start. After starting, the operational loads fall back down significantly. If the generator can’t provide these temporary highs, the equipment will likely fail to start.

A generator with a buffer capacity well over the maximum expected running watt total allows for most surge demands. A 5000-watt unit could maintain a 1500-watt AC alone, 7500+ watts enables successful turn-on of that AC along with concurrently running other devices.
