Venturing out in your RV is all about freedom, but sometimes that freedom comes with power limitations, especially when you’re trying to keep cool. Running your RV’s air conditioner can be a real power hog, often tripping breakers or demanding a huge generator just to get started. That’s where an RV AC soft start kit swoops in to save the day! These clever devices drastically reduce the initial power surge (known as inrush current) your AC needs, letting you start it on smaller generators, 20-amp shore power, or even run multiple ACs on a 30-amp hookup.
If you’re tired of listening to your generator groan or dreading the flicker of lights every time your AC kicks on, investing in the best RV air conditioner soft start is a game-changer. It not only makes your RV life more comfortable but also extends the life of your AC compressor and protects your electrical system. We’ve scoured the market to bring you a comprehensive review of the top options available today.
What is an RV AC Soft Start and Why Do You Need One?
Imagine trying to push a heavy car from a standstill – it takes a huge burst of effort, right? That’s similar to what happens when your RV’s air conditioner compressor first fires up. It demands a massive amount of electricity, called “inrush current,” which can be 5-7 times its normal running current. This surge can overload smaller generators, trip circuit breakers at campgrounds, or put a lot of strain on your RV’s electrical components.
An RV AC soft start kit is a sophisticated electronic device that intelligently manages this startup process. Instead of an abrupt, full-power jolt, it gradually feeds power to the compressor, “softly” easing it into operation. This can reduce the startup current by 65-75%, offering numerous benefits:
- Run AC on Smaller Generators: No need for a massive, noisy generator.
- Use 20A Shore Power: Campgrounds with limited hookups become viable for AC use.
- Run Two ACs on 30A: If you have dual ACs, a soft start on each can enable this.
- Extend AC Lifespan: Less stress on the compressor means it lasts longer.
- Quieter Operation: Less noise and vibration during startup.
- Prevent Breaker Trips: Say goodbye to frustrating power interruptions.
- Boondocking Freedom: Maximize battery and inverter efficiency.

Buyer’s Guide: What to Look for in an RV AC Soft Start
Choosing the best RV air conditioner soft start involves a few considerations to ensure you get the right fit for your rig and needs.
- Current Reduction Capability: This is the most crucial factor. Look for units that promise at least a 65% reduction in startup current. The higher the reduction, the more flexibility you’ll have with smaller generators or shore power.
- Compatibility:
- AC Unit Type: Ensure the soft start is compatible with your RV’s specific AC unit (e.g., 13,500 BTU, 15,000 BTU, single-stage, two-stage, heat pump). Most are widely compatible, but it’s good to check.
- Power Sources: Confirm it works effectively with various power sources like generators, inverters, and different amperage shore power connections (15A, 20A, 30A).
- Ease of Installation: While most soft starts require some basic electrical wiring, some are designed to be more “plug-and-play” than others. Look for clear instructions, color-coded wires, and available video tutorials or customer support for guidance. If you’re not comfortable with electrical work, consider professional installation.
- Durability and Protection: Your RV soft start will be exposed to varying conditions. Look for features like:
- Waterproof/Dustproof Casing: Essential for units mounted near the AC.
- Overload/Short-Circuit Protection: Protects both the soft start and your AC.
- Temperature Resistance: Designed for extreme hot and cold.
- Noise Reduction: A great side benefit of a soft start is a quieter AC startup. If compressor thumps bother you, check reviews for mentions of noise reduction.
- Size and Fit: Especially for newer, low-profile RV AC units, a compact soft start is essential to ensure it fits inside the AC shroud.
- Support and Warranty: A good warranty and accessible customer support (phone, online guides, technician assistance) can be invaluable if you encounter any issues.
Frequently Asked Questions (FAQ)
Q1: How does an RV AC soft start work?
A1: An RV AC soft start uses internal electronics to gradually ramp up the voltage and current to your air conditioner’s compressor. Instead of the compressor kicking on all at once with a huge power surge (inrush current), the soft start delivers power smoothly over a few seconds, significantly reducing the initial power draw and protecting your electrical system.
Q2: Can I install an RV AC soft start myself?
A2: Yes, many RV owners successfully install soft start kits themselves. Most come with detailed instructions, wiring diagrams, and sometimes even video guides. However, it does involve working with electrical components inside your AC unit. If you’re not comfortable with basic electrical wiring, it’s always best to consult a certified RV technician.
Q3: Will an RV soft start allow me to run two ACs on a 30-amp hookup?
A3: Generally, yes! If you install a soft start on each of your RV’s air conditioners, it can often allow you to run both simultaneously on a 30-amp hookup. This is because each soft start significantly reduces the individual startup current, preventing the combined draw from exceeding the 30-amp limit.
Q4: Do I need a soft start for my RV air conditioner if I have a large generator?
A4: While a large generator might handle the inrush current, a soft start still offers benefits. It reduces mechanical stress on your AC compressor, potentially extending its lifespan, and creates a quieter startup. It also frees up more power on your generator for other appliances, making your overall power management more efficient.
Q5: How much power does an RV soft start save?
A5: A soft start doesn’t “save” power in terms of overall consumption during operation, but it drastically reduces the peak power demand during startup. This initial current can be lowered by 65-75%, which is critical for preventing overloads and allowing AC operation on limited power sources.
Q6: Is an RV soft start compatible with all AC units?
A6: Most RV soft starts are designed for broad compatibility with various RV AC brands and models, including different BTUs and single-stage compressors. However, some newer or more complex AC units (like those with two-stage compressors or specific smart features) might require specific soft start models. Always check the product’s compatibility list before purchasing.
Q7: How long do RV AC soft starts typically last?
A7: A high-quality RV AC soft start is built to be durable and should last for many years, often matching or exceeding the lifespan of your AC unit itself. Look for units with waterproof casings, robust internal components, and good warranties to ensure longevity.
