Are you tired of your RV’s air conditioner tripping breakers every time it kicks on? Or perhaps your small generator struggles to get your AC compressor going, limiting your off-grid adventures? You’re not alone! Many RVers face these power struggles, especially when trying to run multiple appliances or when hooked up to limited shore power. Thankfully, there’s a brilliant solution: an easy start RV air conditioner kit, also known as a soft start kit.
These clever devices dramatically reduce the initial surge of power (or “inrush current”) that your RV’s air conditioner demands when it starts up. This means less stress on your generator, fewer tripped breakers, and often, the ability to run your AC on smaller generators or 20-amp household connections. It’s a game-changer for boondockers, campers, and anyone who wants a smoother, quieter, and more efficient cooling experience on the road.
In this article, we’ll dive into the world of RV soft start kits, explain why they’re essential, and review 10 of the best options available today. Let’s get your RV air conditioning running like a dream!
What Makes an RV Soft Start Kit a Game-Changer?
Before we jump into the reviews, let’s quickly understand the benefits of integrating an easy start RV air conditioner solution into your setup:
- Reduced Startup Current: This is the primary benefit, cutting the initial power surge by 65-75%. This prevents your generator from bogging down or your circuit breaker from tripping.
- Smaller Generator Compatibility: Run your 13,500 BTU or even 15,000 BTU AC with a compact 2000-2200W portable generator – a huge win for boondocking!
- Run More Appliances Simultaneously: With the AC starting gently, you’ll have more available power for your microwave, fridge, lights, and other essentials.
- Quieter Operation: Soft starts lead to smoother, quieter compressor startups, eliminating that loud “thump” and making for a more peaceful environment.
- Extended AC Lifespan: Reducing the mechanical stress on your compressor motor during startup can significantly prolong the life of your valuable RV air conditioning unit.
- Flexible Power Options: Easily run your AC on a standard 20-amp household plug or even two ACs on a 30-amp RV hookup (with two soft starters).

Frequently Asked Questions about RV AC Soft Start Kits
Here are some common questions RVers have about these handy devices:
Q1: What exactly is an easy start RV air conditioner kit?
An easy start RV air conditioner kit, or soft start kit, is an electrical device designed to reduce the high “inrush current” that an AC compressor draws when it first starts. Instead of a sudden jolt of power, the soft start gradually ramps up the voltage, allowing the AC to start smoothly and with significantly less power demand.
Q2: Why do I need an RV AC soft start kit?
You need one if you frequently experience tripped circuit breakers when your AC starts, if your generator struggles to power your AC, or if you want to run your AC on a smaller generator (like a 2000-2200W portable unit) or a 20-amp household connection. They also reduce noise and extend the lifespan of your AC unit.
Q3: How does an RV soft start kit work?
Traditional AC compressors draw a massive amount of current (up to 7 times their running current) for a fraction of a second when they first start. A soft start kit uses smart electronics to manage this process, essentially “softening” the initial power surge by limiting the current gradually, instead of all at once.
Q4: Can I install an RV soft start kit myself, or do I need a professional?
Many soft start kits are designed for DIY installation and come with detailed instructions, wiring diagrams, and even video tutorials. Some kits are truly plug-and-play. However, if you’re uncomfortable with electrical wiring or working on your RV’s rooftop AC unit, it’s always a good idea to consult a certified technician.
Q5: What size generator do I need if I have a soft start kit?
With an easy start RV air conditioner kit installed, you can typically run a 13,500 BTU or even a 15,000 BTU RV AC unit with a much smaller generator, often in the 2000-2200W range. Without a soft start, you’d usually need at least a 3000-3500W generator for similar AC units.
Q6: Will an RV soft start kit truly reduce the noise of my air conditioner?
Yes, absolutely! The sudden “thump” or loud growl you hear when your AC compressor kicks on is largely due to the high inrush current. By smoothing out this startup, soft start kits significantly reduce both the mechanical vibration and the audible noise, leading to a much quieter and more pleasant RV experience.
Q7: Are RV soft start kits compatible with all RV AC units?
Most soft start kits are designed to be widely compatible with popular RV AC brands like Dometic, Coleman, Atwood, Advent, GE, and Airxcel. However, it’s always best to check the specific product’s compatibility list against your AC unit’s make, model, and BTU rating to ensure a perfect match.
Final Thoughts on Easy Start RV Air Conditioners
Investing in an easy start RV air conditioner kit is a smart move for any RVer looking to enhance their comfort and flexibility on the road. Whether you’re aiming for more peaceful boondocking, struggling with limited campground power, or simply want to extend the life of your RV’s valuable appliances, a soft start kit delivers undeniable benefits.
