Hitting the open road in your RV is all about freedom, but sometimes that freedom comes with a warm cabin, especially when you’re boondocking or dry camping without shore power. Most RV air conditioners (ACs) are power-hungry beasts, especially during startup, often needing a surge of power that a smaller generator just can’t provide. That’s where the quest for the best 2000 watt generator for RV air conditioner really begins – and often ends with a smart solution: a soft start device.
Many RVers want to use a compact, quiet, and fuel-efficient 2000-watt inverter generator to power their 13,500 BTU or 15,000 BTU RV AC. The good news? It’s totally possible! The secret lies in pairing that generator with a specialized “soft start” module. This device dramatically reduces the initial power surge an AC compressor demands, allowing your smaller generator to handle the load gracefully.
In this article, we’ll dive into the top soft start solutions and the best 2000-watt class generators, plus some innovative cooling options, to keep your RV cool and comfortable on your adventures. Let’s find the perfect setup for your rig!
Why a 2000-Watt Generator Needs a Little Help (Introducing Soft Starters)
Your RV’s air conditioner, particularly its compressor, requires a significant burst of electricity to kick on. This initial “starting wattage” or “LRA” (Locked Rotor Amps) can be 3-7 times higher than its continuous “running wattage.” A standard 13,500 BTU RV AC might run on about 1,500-2,000 watts, but its startup could demand 3,000-4,000 watts! That’s far more than a typical 2000-watt generator can deliver.
Soft start devices act like a power buffer. They intelligently ramp up the power to the AC compressor over a few seconds, instead of all at once. This smooth startup drastically cuts down the power surge, allowing smaller generators, like our target 2000-watt models, to power your RV AC without tripping breakers or stalling out. They’re a game-changer for anyone looking to optimize their boondocking experience.

What to Look For When Choosing Your Setup
To ensure you pick the best 2000 watt generator for RV air conditioner needs (plus the right soft start), consider these factors:
- Generator Running & Starting Watts: Make sure the generator’s running watts can handle your AC’s running watts, and that the soft start effectively lowers the AC’s starting watts to below the generator’s surge capacity.
- Noise Level: For RV camping, especially in shared spaces or quiet zones, a generator with low decibels (dB) is crucial. Inverter generators are typically the quietest.
- Fuel Efficiency: Look for features like “Eco Mode” or “Smart Throttle” to conserve fuel, extending your run time on a single tank.
- Clean Power (THD): If you plan to power sensitive electronics like laptops, TVs, or your RV’s control panel, choose an inverter generator with a Total Harmonic Distortion (THD) of 5% or less.
- Portability & Weight: A 2000-watt generator should be relatively lightweight and easy to carry, especially if you’ll be moving it frequently.
- Outlets: Ensure it has the necessary outlets (e.g., 120V AC, USB, 12V DC, and ideally a TT-30R RV-ready outlet if it’s a larger model).
- Parallel Capability: If you think you might need more power in the future, a generator that can be paralleled with another unit is a smart investment.
- Soft Start Compatibility: Verify that the soft start device is compatible with your specific RV AC model.
- Installation Ease for Soft Starts: While many offer DIY guides, consider your comfort level with electrical work.
FAQ Section
Q1: Can a 2000-watt generator really run my RV air conditioner?
A1: Yes, absolutely! While most standard RV AC units (13,500 BTU or 15,000 BTU) have a startup power draw that exceeds a 2000-watt generator’s capacity, pairing the generator with a soft start device makes it possible. The soft start significantly reduces the AC’s initial power surge.
Q2: What is a soft start device and how does it work?
A2: A soft start device is an electronic module installed on your RV’s AC compressor. Instead of allowing the compressor to demand a huge rush of power all at once when it starts, the soft start gradually ramps up the voltage and current over several seconds. This smooths out the startup, drastically reducing the peak power draw, often by 65-75%.
Q3: Is installation of a soft start device difficult?
A3: For most soft start devices, installation involves basic electrical wiring skills and tools. Manufacturers often provide detailed guides, video tutorials, and even live technical support. If you’re comfortable with simple wiring, it’s a DIY project; otherwise, a qualified RV technician can install it for you.
Q4: Will a soft start device void my RV AC warranty?
A4: Generally, no. Most soft start manufacturers design their products to be compliant and not interfere with AC warranties. In fact, by reducing stress on the compressor, a soft start can potentially extend the life of your AC unit. Always check with your AC manufacturer if you have concerns.
Q5: What size generator do I need for my RV AC without a soft start?
A5: Without a soft start, a 13,500 BTU RV AC typically requires a generator with at least 3,000 to 3,500 running watts and even higher surge wattage. A 15,000 BTU AC would likely need 3,500-4,000+ running watts. This often means a larger, heavier, and louder generator.
Q6: Can I run other appliances while my 2000-watt generator is powering the AC (with a soft start)?
A6: It depends on the generator’s remaining capacity and the power draw of your other appliances. A 2000-watt generator typically provides around 1,600 running watts. Once your AC is running (consuming maybe 1,200-1,800 watts), you’ll have limited power left for high-draw items like microwaves or hair dryers. Low-wattage appliances like lights, phone chargers, or a TV might be fine.
Q7: Are inverter generators better than conventional generators for RV ACs?
A7: Yes, inverter generators are almost always preferred for RV use, especially for sensitive electronics and ACs. They produce “clean power” (pure sine wave) with low THD, which is safer for your RV’s sensitive electronics. They are also significantly quieter, more fuel-efficient, and often more portable than conventional generators.
Q8: What is “boondocking” and how does a 2000-watt generator help?
A8: Boondocking (or dry camping) refers to camping without hookups to electricity, water, or sewer. A 2000-watt generator, particularly when paired with a soft start for your AC, allows you to enjoy comfortable cooling and power for other essentials, extending your time off-grid in remote or dispersed camping locations.
Conclusion
Finding the best 2000 watt generator for RV air conditioner needs isn’t just about picking a generator; it’s about creating a smart, efficient power solution. By combining a reliable, quiet 2000-watt inverter generator with a high-quality soft start device, you unlock the ability to keep your RV cool and comfortable virtually anywhere.
Whether you opt for the proven performance of a Micro-Air EasyStart or the robust support of SoftStartRV, these devices are truly transformative for small generator owners. Pair them with a quiet workhorse like the A-iPower 2000W or a versatile WEN Dual Fuel unit, and you’ll have a powerful, portable, and fuel-efficient setup for all your RV adventures. Don’t let power limitations dictate your travel plans – embrace the freedom of efficient cooling on the go!
