What Size Generator for Camper? Pop-Up, 30 Amp & RV Chart
If you are asking what size generator you need for a camper, start with the camper type, the air conditioner size, and whether your rig uses a 30 amp or 50 amp electrical service.
Quick answer: most pop-up campers can use a 2,000W to 2,400W inverter generator for lights, charging, a small fridge, and basic campsite loads. Most 30 amp travel trailers with a 13,500 or 15,000 BTU RV air conditioner need a 3,500W to 4,500W inverter generator. Larger motorhomes or 50 amp RVs often need 6,000W to 8,000W, especially when running more than one air conditioner.
Camper Generator Size Chart
This chart answers the common search questions: what size generator for camper, how big of a generator to run a camper, and how many watt generator to run a camper.
| Camper Type | Common Power Needs | Recommended Generator Size | Best Fit |
|---|---|---|---|
| Pop-up camper / A-frame / small camper | Lights, device charging, small fridge, fan, coffee maker used carefully | 2,000W to 2,400W inverter generator | Lightweight camping power without oversizing |
| Small travel trailer without AC use | Battery charging, lights, fridge controls, laptop, router, small appliances | 2,400W to 3,000W inverter generator | Quiet basic power when the air conditioner is not required |
| 30 amp camper or travel trailer with one RV AC | 13,500 or 15,000 BTU rooftop AC, microwave used separately, fridge, lights | 3,500W to 4,500W inverter generator | Most common answer for 30 amp RV camping |
| Large fifth wheel or motorhome | Multiple appliances, higher surge loads, possible dual AC use | 6,000W to 8,000W generator | High-capacity RV and backup power needs |
| 50 amp RV | Two air conditioners, larger appliances, more simultaneous loads | 6,800W+ or paired generator setup | Best for users who need more than basic campsite power |
Rule of thumb: choose enough wattage for your normal running load plus the highest starting surge from one major appliance, usually the RV air conditioner.
What Size Generator for Pop Up Camper?
For the GSC query generator for pop up camper, the most useful answer is direct: a pop-up camper usually does not need a large 4,500W generator unless you plan to run a high-draw air conditioner or several heavy appliances at the same time.
A 2,000W to 2,400W inverter generator is usually the best generator size for a pop-up camper because it can cover typical campsite loads while staying easier to move, store, and manage.
Good Match
Lights, phones, laptops, small fridge, fan, battery charging, and light kitchen use when managed one appliance at a time.
Watch the Surge
Coffee makers, kettles, microwaves, and AC compressors can spike power demand. Do not judge only by running watts.
Do Not Oversize
For simple pop-up camper power, a much larger generator may add weight, noise, fuel use, and storage hassle.
What Size Generator Do I Need for a 30 Amp Camper?
For a 30 amp camper, the practical answer is usually 3,500W to 4,500W. A 30 amp RV connection can theoretically use up to 3,600 watts at 120V, but generator sizing also has to account for startup surge from the air conditioner.
If your 30 amp camper has a 13,500 or 15,000 BTU rooftop AC, a 2,000W generator is usually too small. A 4,500W inverter generator gives more headroom for AC startup, fridge operation, lights, charging, and occasional microwave use when loads are managed properly.
What Size Generator Do I Need for a Travel Trailer?
Most travel trailer owners are trying to power three things: the RV air conditioner, the refrigerator system, and normal campsite essentials. If you want to run the AC, the best generator size for a travel trailer is commonly 3,500W to 4,500W.
If you do not need AC, a smaller inverter generator may be enough. If you want to run AC and a microwave at the same time, you may need more capacity or you may need to run one high-draw appliance at a time.
How Many Watts Does It Take to Run a Camper?
To calculate camper generator size, list the appliances you want to run at the same time, add their running watts, then add the largest starting surge. Motors and compressors usually need more power at startup than they do while running.
| Appliance | Typical Running Watts | Typical Starting Watts | Generator Sizing Note |
|---|---|---|---|
| 13,500 BTU RV air conditioner | 1,300W to 1,500W | 2,800W to 3,200W | Often the main reason a camper needs 3,500W+ |
| 15,000 BTU RV air conditioner | 1,500W to 1,800W | 3,000W+ depending on unit and conditions | Choose more headroom for hot weather and older AC units |
| Microwave | 1,000W to 1,500W | 1,000W to 1,500W | Avoid running it with AC startup on smaller generators |
| Portable fridge or freezer | 300W to 700W | 600W to 1,200W | Check the appliance label for accurate numbers |
| Coffee maker or electric kettle | 800W to 1,500W | 800W to 1,500W | Use one heavy appliance at a time on smaller setups |
| LED lights, phone charging, laptop | 5W to 150W | Usually minimal | Small loads rarely decide generator size |
Can a 2000 Watt Generator Run a Camper?
A 2,000 watt generator can run a small camper or pop-up camper if you are powering basic loads such as lights, charging, a small fridge, and a fan. It is usually not the right choice for starting a standard RV rooftop air conditioner.
If your search is can a 2000 watt generator run a camper, the better answer is: yes for light camping power, no for most RV AC use. For AC, move up to the 3,500W to 4,500W range.
Inverter Generator vs Open-Frame Generator for Campers
Modern campers often include sensitive electronics such as converters, thermostats, TVs, routers, and battery chargers. For RV and camper use, an inverter generator is usually the better fit because it is designed to provide cleaner power and a quieter camping experience than many open-frame jobsite generators.
When choosing a generator for a camper, look for the right wattage, RV-ready outlet compatibility where needed, manageable noise, and enough surge capacity for the appliances you actually use.

Frequently Asked Questions
What size generator do I need for my camper?
For a small camper or pop-up camper, start around 2,000W to 2,400W. For a 30 amp camper with one RV air conditioner, start around 3,500W to 4,500W. For larger RVs or 50 amp setups, consider 6,000W to 8,000W or more depending on the load.
What size generator for pop up camper?
A 2,000W to 2,400W inverter generator is usually the best size for a pop-up camper when you are powering lights, charging, a small fridge, fan, and occasional small appliances.
What size generator for 30 amp camper?
Most 30 amp campers with one rooftop AC are better matched with a 3,500W to 4,500W inverter generator. This gives more surge capacity for AC startup than a small 2,000W unit.
Can a 2000 watt generator run a camper air conditioner?
Usually no. A 2,000W generator may run basic camper loads, but most RV rooftop air conditioners need a larger generator because of compressor starting surge.
How big of a generator to run a camper and microwave?
If you want to run a camper air conditioner and microwave, a 4,500W class generator is often a better starting point. On smaller generators, avoid running high-draw appliances at the same time.
Choose the Right Camper Generator Before Your Next Trip
Match your generator to the camper type, AC size, and real appliance load. For simple pop-up camper power, compare the 2400P. For many 30 amp travel trailers, compare the 4500PD Series. For larger RV and home backup needs, review the 6800PD/PT Series.
