Quick Answer
For camping with a trailer, a 2000-2500 watt generator is often sufficient to power essential appliances like lights, refrigerators, and water pumps, while also providing some power for charging devices.
Choosing the Right Generator Size
When selecting a generator for camping with a trailer, it’s essential to consider your specific needs and the appliances you plan to power. A general rule of thumb is to choose a generator that provides 10-20% more power than your maximum expected load. For example, if you have a 1500 watt refrigerator, a 2000 watt generator would be a good choice to account for other power-hungry appliances.
Calculating Your Power Needs
To determine the right generator size for your trailer, make a list of the appliances you plan to power and their respective wattages. Start with essential items like lights, refrigerators, and water pumps, and then consider adding power for charging devices like laptops and cell phones. Don’t forget to include any power-hungry appliances like air conditioners or microwaves, if you plan to use them. A rough estimate of the total power needs for a typical trailer setup is:
- Refrigerator: 1500-2000 watts
- Lights: 100-200 watts
- Water pump: 200-400 watts
- Laptop charging: 65 watts
- Cell phone charging: 5-10 watts
Generator Sizing Considerations
When choosing a generator, also consider other factors like efficiency, noise level, and fuel type. Look for a generator with a high surge capacity to handle the initial power spikes when starting appliances. A diesel or propane generator may be a better choice for larger trailers or those that require high power output. Always check the generator’s specifications and manufacturer recommendations to ensure it meets your needs and complies with local regulations.
