Aoteda Soft Start for RV A/C
The Aoteda soft starter enables a 2200 BTU air conditioner to start with a 15,000W generator, freeing you to run other appliances. Best for RV enthusiasts who want to avoid buying a larger generator and need dependable power for a fridge, heater, microwave, or TV while the A/C starts. It claims a 65–70% decrease in starting current, which helps prevent generator overload and reduces tripping risk.
Who this is best for: RV users with limited generator capacity who need reliable startup and support for other devices. Caution: proper installation is required to maintain compatibility with your setup. If using two A/C units on a single 30A hookup, two soft starters are recommended.
SoftStartRV Soft Start for RV A/C
This kit emphasizes compact size and waterproof design, suitable for low-profile RV A/C units. It supports starting two A/Cs on 30A or one on a smaller generator, enabling use with a 15A or 20A hookup. It’s marketed as capable of powering a 2200W generator while handling a total BTU load up to 36,000 BTU. It also targets quieter starts to reduce vibration and improve nocturnal comfort.
Who this is best for: RV owners seeking a robust, waterproof solution that can handle multiple appliances on a shared circuit. Limitation: installation requirements may vary by RV model; verify compatibility with your A/C unit and electrical setup.
TURBRO RV AC Soft Start Kit
The TURBRO kit advertises a 60–75% reduction in startup current, helping avoid breaker trips on a 30A hookup and supporting up to 15,000 BTU units. It is designed for non-inverter RV ACs and claims versatility across RVs, travel trailers, and campers. The kit includes indicators and supports running two A/Cs with soft starts on a 30A supply when used in pairs.
Who this is best for: RV owners with older or higher-current A/Cs on standard park power who want a reliable, broad-voltage solution. Limitation: best results are achieved with installations that match the described amperage and unit size; verify compatibility with your specific A/C model.
Soft Start for RV Air Conditioner – Toiwrudo
The Toiwrudo kit claims up to a 70% reduction in startup current, designed to be compatible with standard RV air conditioners and avoid tripping the circuit when used with a small generator. It is positioned for easy installation and broad compatibility, including use with 15,000 BTU rooftop A/C units and common RV power sources.
Who this is best for: RV travelers using compact generators or 20A/30A hookups who want a straightforward install and reliable startup. Limitation: explicit compatibility lists should be checked for your specific A/C model and generator capacity.
MICRO-AIR EasyStart Breeze 399
The EasyStart Breeze 399 covers RV A/C systems up to 13k–15k BTU and supports up to two units on a 30A supply with a 2200W generator. It emphasizes quieter startup and a compact installation design to save space in tight RV setups.
Who this is best for: RV owners seeking a compact, low-noise option with clear compatibility for two A/C configurations. Limitation: may not support very large rooftop units beyond its stated BTU range.
ZUCCIO 16-32A Soft Start Module
The ZUCCIO module reduces startup current by up to 70% and includes reverse motor protection to extend compressor life. It supports 16–32A circuits and is designed for home or RV use with DIY installation. The kit aims to prevent voltage dips and trips on older circuits while offering quiet startup.
Who this is best for: users needing a DIY-friendly soft start with protective features for older electrical systems. Limitation: DIY installation requires basic electrical skills to avoid miswiring or improper connections.
Buying Guide: Key Considerations for RV A/C Soft Starts
What size A/C do you run? Consider BTU ratings (e.g., 13k–15k vs. 20k–24k BTU) to select a soft start that can handle the load without tripping breakers.
What is your power source? If you rely on 20A, 30A, or small generators (like 2200W), choose a model explicitly designed for those limits to maximize performance without overloading your system.
Single or multiple A/C units? Some options support one unit on a generator and two on a 30A hookup. If you plan to run multiple devices, ensure the unit supports multi-appliance startup.
Installation and compatibility: Some products are plug-and-play, while others require wiring and professional installation. Verify compatibility with your A/C brand, RV model, and electrical configuration before buying.
Noise and vibration: A softer start often reduces compressor noise and vibrations, improving night-time comfort. Consider models that emphasize quieter operation if this matters for you.
Durability and protection: Look for waterproofing, reverse motor protection, and overcurrent safeguards to extend the life of your A/C and soft start components.
Warranty and support: Check what the seller covers and whether there is technical support for installation questions or troubleshooting.
Frequently Asked Questions
- What is a soft start circuit for an RV air conditioner? A soft start circuit reduces the electrical surge when the compressor starts, easing strain on generators, inverters, and the RV electrical system.
- Will a soft start work with a small generator? Yes, most options are designed to let a 2200W generator start a typical 13k–15k BTU A/C and run other appliances.
- Can I install a soft start myself? Many kits are DIY-friendly, but some require basic electrical wiring. Follow manufacturer instructions and safety guidelines.
- Do I need one soft start per A/C? If you have two A/C units on a shared 30A circuit, you may need two soft starts for optimal performance and to prevent overloading.
- Will a soft start reduce noise? Yes, many models advertise quieter compressor startup by limiting surge and vibration.
- Are soft starts compatible with all RVs? Most are compatible with a wide range of RVs, but always verify compatibility with your specific A/C unit and electrical setup.
