Are you planning a trip with your RV and wondering what size generator you need to keep your air conditioner running smoothly? Choosing the right generator size is crucial to stay cool and comfortable without overloading your power source.
If your generator is too small, your AC won’t run properly, and if it’s too big, you could be wasting money and fuel. You’ll discover exactly how to find the perfect generator size for your RV air conditioner. Keep reading to avoid common mistakes and enjoy your travels without breaking a sweat.
Rv Air Conditioner Power Needs
RV air conditioners need different power levels to run well. The typical running wattagefor a small RV AC is about 1,200 to 1,500 watts. Larger units may use up to 2,000 watts. The starting wattsare higher. This is the extra power needed when the AC first turns on. It can be 2 to 3 times the running watts. So, a 1,500-watt running unit might need 3,000 to 4,500 starting watts.
The type and size of the air conditioner also affect power needs. Roof-mounted AC unitsoften use less power than window units. Bigger ACs cool more space but need more energy. Knowing these numbers helps choose the right generator size for your RV.

Choosing The Right Generator Size
Choosing the right generator size is key to running your RV air conditioner smoothly. The generator must handle the starting and running wattsof the AC unit. Most RV air conditioners need 2,000 to 3,500 wattsto start and about 1,200 to 1,800 wattsto run.
Consider other RV appliances like lights, fridge, and microwave. These add to the total power needed. It’s smart to choose a generator with extra capacityfor these devices.
Air conditioners use more power when they start. This peak power demandcan be 2-3 times the running watts. Pick a generator that can handle these surges without tripping.
| Appliance | Starting Watts | Running Watts |
|---|---|---|
| RV Air Conditioner | 2,000 – 3,500 | 1,200 – 1,800 |
| Refrigerator | 600 – 1,200 | 200 – 600 |
| Lights | 100 – 300 | 50 – 150 |
Types Of Generators For Rv Use
Portable generatorsare easy to carry and use. They run on gasoline and are good for short trips. These generators can handle small to medium power needs, including RV air conditioners. They are usually loud and may not be the best for quiet campsites.
Inverter generatorsprovide clean and stable power. They are quieter and more fuel-efficient than portable types. Inverter generators are great for sensitive electronics and can adjust power output based on demand. This saves fuel and reduces noise.
Dual-fuel and solar optionsoffer more flexibility. Dual-fuel generators can run on gasoline or propane, giving you more fuel choices. Solar generators use sunlight to produce power, which is quiet and eco-friendly. However, solar power may not always meet high energy needs like running an RV air conditioner continuously.
Calculating Total Power Needs
List all devices you want to power in your RV. Include lights, fridge, TV, and especially the air conditioner. Write down each device’s running wattageand starting wattage. Starting wattage is higher for some devices like the AC.
Calculate total running watts by adding all running wattages. Then, add the highest starting wattage to the total. This gives you the peak power neededto start and run everything.
Include a safety margin to avoid overload. Add about 20-25% extra powerto the total watts. This helps the generator run smoothly without strain. It also covers small power surges or future devices.
| Device | Running Watts | Starting Watts |
|---|---|---|
| Air Conditioner | 1500 | 2200 |
| Fridge | 200 | 600 |
| Lights | 100 | 100 |
| TV | 100 | 100 |
Generator Features To Consider
Noise levelsmatter a lot for RV trips. A quiet generator keeps your stay peaceful. Choose models with noise ratings under 60 decibels for comfort.
Fuel efficiencyhelps save money and reduces trips to refill. Generators using less fuel per hour run longer and cost less to operate.
Portability and weightaffect how easy it is to move your generator. Lighter, compact designs fit better in small spaces and are easier to carry.
Runtime and fuel tank sizedecide how long the generator works without stopping. Bigger tanks mean longer power but add weight. Balance your need for time and portability.

Installation And Safety Tips
Proper ventilationis key to keep your RV safe and cool. Make sure the generator is placed in an open area. Avoid spots with blocked airflow. This prevents overheating and lets fumes escape.
Grounding and wiringare essential to avoid electric shocks. Connect the generator to your RV using the right cables. Use a ground fault circuit interrupter (GFCI)for extra safety. Check connections often for wear or damage.
- Avoid carbon monoxide risksby never running the generator inside the RV.
- Keep the generator far from doors and windows.
- Install carbon monoxide detectorsinside the RV for early warnings.
- Turn off the generator before sleeping to stay safe.
Maintaining Your Generator
Keep your generator in good shape for the best performance. Regular oil changes and air filter checks help it run smoothly. Clean or replace spark plugs to avoid start-up problems. Check for loose wires or parts that might cause issues.
Store fuel safely in approved containers, away from heat or sparks. Use fresh fuel to prevent clogging. Add fuel stabilizers if storing for a long time. Always refill the tank before a trip to avoid running out.
| Common Issue | Possible Cause | Simple Fix |
|---|---|---|
| Generator won’t start | Empty fuel tank or old fuel | Refill or replace fuel |
| Low power output | Dirty air filter or spark plug | Clean or replace parts |
| Overheating | Blocked ventilation or oil level low | Clear vents and check oil |
