1. Determining the Right Size Generator for Your Travel Trailer
Choosing the correct generator size is crucial for powering your travel trailer effectively. A generator that’s too small won’t run your appliances, while one that’s too large is inefficient and bulky. Understanding your power needs is the first step in making the right choice.
1.1. Calculating Your Power Needs
To figure out what size generator for travel trailer you need, start by listing all the appliances you plan to use simultaneously. For each appliance, note its running wattage (the power it needs to operate) and its surge wattage (the power it needs to start). Add up all the running wattages, then add the highest surge wattage from your list.
Total Required Wattage = Total Running Wattage + Highest Surge Wattage
This total will give you a good estimate of the minimum generator size you need. For example, if your appliances have a total running wattage of 2000 watts and the highest surge wattage is 1000 watts, you’ll need at least a 3000-watt generator.

5. Specific Generator Sizing for Different Camper Types
To further refine your understanding of what size generator for travel trailer you need, let’s look at specific sizing recommendations for different camper types.
5.1. Generator Size for 30-Amp Campers
A 30-amp RV has one 30-amp service leg for powering appliances and outlets of 120 volts. Using the formula:
Wattage = Volts x Amperes
Wattage = 120 V x 30 Amp
Wattage = 3,600 watts
This means a 30-amp camper can use a shore power of 3,600 watts. So, the highest wattage you can use is 3600, making a 4,000-watt generator a suitable choice. On average, a 2,000 to 2,500-watt generator is a good fit for 30-amp campers.
5.2. Generator Size for 50-Amp Campers
Larger RVs provide two legs of 50-amp service. Multiplying the maximum power handling by two:
Wattage = Volts x Amperes
Wattage = 120 V x 50 Amp
Wattage = 6000 watts
Maximum power handling = 2 x 6,000 watts = 12,000 watts
Therefore, you can use a maximum of 12,000-watt generator for a 50-amp RV.
5.3. Generator Size for 50-Amp RVs with 2 AC Units
A 50-amp RV with two AC units typically needs a generator that has a power output of 4,000–8,000 watts. However, this may vary depending on the wattage of the RV AC and how long you would run two ACs.
For example, if each AC unit consumes around 600-1700 watts, you’ll need a generator that can supply more than that. The Jackery Solar Generator 2000 Plus Kit (4kWh) with a battery capacity of 4085.6Wh can run RV ACs for 1.0 – 2.8 hours, depending on the wattage consumption.
5.4. Generator Size for a 25-Foot Travel Trailer
To determine what size generator for travel trailer, specifically a 25-foot model, we can calculate as follows:
A 25-amp travel trailer will run on 120V and 25A.
Wattage = Voltage × Current = 120V × 25A = 3000W
This means a 3000-watt generator will be ideal for a 25-foot travel trailer. If you need some additional or spare power, you may go ahead with a 3500-watt generator for RV.
