What Size Generator for Camper? Pop-Up, 30 Amp & RV Chart
Find the right generator size for a pop-up camper, 30 amp travel trailer, or larger RV. Use this 2026 wattage chart to match your camper type, air conditioner size, and real appliance load before your next trip.
Quick answer: a small pop-up camper usually needs a 2,000W to 2,400W inverter generator for lights, charging, a small fridge, fans, and light appliances. A 30 amp camper with one 13,500 or 15,000 BTU RV air conditioner usually needs a 3,500W to 4,500W inverter generator. Larger RVs, fifth wheels, dual-AC setups, or heavier appliance use may need 6,000W to 8,000W+ or a professionally planned power setup.

Camper Generator Size Chart
This chart answers the main sizing questions: what size generator for camper, how big of a generator to run a camper, what size generator for 30 amp camper, and what size generator for pop up camper.
| Camper Type | Typical Power Needs | Recommended Generator Size | Best Fit |
|---|---|---|---|
| Pop-up camper / A-frame camper | Lights, phone charging, small fridge, fan, battery charging, occasional coffee maker | 2,000W to 2,400W inverter generator | Quiet, lightweight camping power without oversizing |
| Small camper without AC use | Battery charger, LED lights, fridge controls, laptop, router, small appliances used one at a time | 2,400W to 3,000W inverter generator | Basic campsite power when rooftop AC is not required |
| 30 amp camper / travel trailer with one RV AC | 13,500 or 15,000 BTU rooftop AC, refrigerator, lights, charging, occasional microwave | 3,500W to 4,500W inverter generator | Most common range for 30 amp RV camping |
| Large travel trailer / fifth wheel | Higher appliance load, larger AC, microwave, battery charging, more simultaneous use | 4,500W to 6,800W+ | More headroom for hot weather and heavier loads |
| 50 amp RV or dual-AC RV | Two AC units, larger appliances, high simultaneous demand | 6,000W to 8,000W+ or a planned RV power setup | Not every portable generator can supply full 50 amp RV service; size by the exact loads you will run |
Rule of thumb: add your running watts, then add the largest startup surge from one major appliance. For many campers, the rooftop air conditioner is the load that decides generator size.
What Size Generator for Pop Up Camper?
For a pop-up camper, the best generator size is usually 2,000W to 2,400W. This covers the loads most pop-up camper owners actually use: lights, device charging, a small fridge, fan, battery charging, and occasional light appliance use.
A large 4,500W generator is usually unnecessary for a simple pop-up camper unless you plan to run a high-draw air conditioner, a microwave, or multiple heavy appliances at the same time. For searchers comparing a generator for pop up camper, the strongest practical answer is: choose the smallest inverter generator that can handle your real peak load with safe headroom.
Best Size
2,000W to 2,400W is the normal sweet spot for simple pop-up camping power.
Use Case
Lights, charging, small fridge, fan, battery charging, and one small appliance at a time.
When to Size Up
Move higher if your pop-up camper has AC or you want more appliance headroom.
What Size Generator Do I Need for a 30 Amp Camper?
A 30 amp camper uses 120V service, so the theoretical maximum is about 3,600 watts. In real use, generator sizing is not just about the 30 amp plug. You also need enough starting wattage for the RV air conditioner compressor.
For most 30 amp campers with one 13,500 or 15,000 BTU rooftop AC, a 3,500W to 4,500W inverter generator is the practical range. A 2,000W generator may run lights and charging, but it is usually too small for reliable RV AC startup.
If your camper has a soft-start kit on the air conditioner, your startup demand may be lower. If you are camping in hot weather, using an older AC unit, or running a microwave and AC close together, choose more headroom.
What Size Generator Do I Need for a Travel Trailer?
Most travel trailers need either a small generator for basic campsite power or a larger generator for air conditioning. Without AC, many travel trailers can operate on a 2,400W to 3,000W inverter generator if appliances are managed carefully. With one rooftop AC, most users should start in the 3,500W to 4,500W class.
If you want to run the AC, microwave, coffee maker, and battery charger at the same time, you may need a larger generator or you may need to manage loads one at a time. The safest sizing method is to check the appliance labels in your RV and compare both running watts and starting watts.
How Many Watts Does It Take to Run a Camper?
To calculate camper generator size, list what you need to run at the same time. Add the running watts, then add the largest starting surge. Motors and compressors usually draw much more power for a few seconds when they start.
| Camper 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 | Main reason many campers need 3,500W+ |
| 15,000 BTU RV air conditioner | 1,500W to 1,800W | 3,000W+ depending on model and conditions | Choose extra headroom in hot weather |
| Microwave | 1,000W to 1,500W | Usually similar to running watts | Avoid running with AC startup on smaller generators |
| RV refrigerator / small fridge | 300W to 700W | 600W to 1,200W | Check the appliance label for exact numbers |
| Coffee maker / electric kettle | 800W to 1,500W | Usually similar to running watts | Use one heavy appliance at a time |
| Battery charger / converter | 300W to 1,000W | Varies by system | Can add meaningful load while charging depleted batteries |
| LED lights, phone charging, laptop | 5W to 150W | Minimal | Small loads rarely decide generator size |
Can a 2000 Watt Generator Run a Camper?
Yes, a 2,000 watt generator can run a small camper or pop-up camper when you are powering light loads: lights, charging, a small fridge, a fan, and maybe one small appliance at a time. It is not usually the right choice for starting a standard RV rooftop air conditioner.
For the query can a 2000 watt generator run a camper, the best answer is: yes for basic camper power, usually no for RV AC. If AC matters, move up to the 3,500W to 4,500W range.
Can a 3000 Watt Generator Run a Camper?
A 3,000 watt generator can run many small camper loads and may run some smaller RV air conditioners, especially if the AC has a soft-start kit. However, it can still be tight for a 13,500 or 15,000 BTU rooftop AC plus normal appliances.
If you want a more comfortable setup for a 30 amp camper, a 4,500W class inverter generator usually gives better startup headroom and fewer load-management problems.
Inverter Generator vs Open-Frame Generator for Campers
For camper and RV use, an inverter generator is usually the better fit. Campers often include sensitive electronics such as converters, thermostats, TVs, routers, and battery chargers. Inverter generators are designed to provide cleaner power and a quieter campsite experience than many open-frame jobsite generators.
When comparing a camper generator, look at wattage, starting watts, outlet compatibility, sound level, fuel type, weight, and whether the generator is easy to move around the campsite.

See the ERAYAK 6800PD/PTGenerator Safety for Camper and RV Use
Important safety notice: never run a generator inside a camper, RV, tent, garage, truck bed cap, or any enclosed or partially enclosed space. Operate the generator outdoors with exhaust pointed away from people, doors, windows, vents, and neighboring campsites. Use a working carbon monoxide alarm in your RV, keep the generator dry, use properly rated outdoor cords, and follow your generator manual, RV manual, campground rules, and local electrical requirements.
