Features

  • Plug & Play RV A/C Soft Start No Installation Required: Skip the tools, wiring, rooftop access, and installer. Simply plug SoftStartUp into your power source, connect your RV, and help your air conditioner start smoothly from campground power, generator power, or another compatible power source.
  • Maximize Limited RV Power: Designed for travel trailers, Class B, and Class C RVs, SoftStartUp helps maximize your available power supply so you can run your RV A/C and multiple appliances with fewer nuisance breaker trips, less light flickering, and reduced risk of overload.
  • Works with 30A/50A Power Sources & Small Generators: SoftStartUp works with 30-amp and 50-amp power sources and small generators as low as 2200 watts, helping you get more from your existing power setup without expensive rewiring or upgrading to a larger generator.
  • Reduces Startup Surge and Helps Extend Equipment Life: SoftStartUp reduces startup inrush current by up to 50%, helping prevent power surges that can trip circuit breakers. Built-in overload protection helps reduce mechanical stress during startup, lowering wear and tear on your RV A/C compressor and connected appliances.
  • Weatherproof, Portable Design and Free Adapter Included Check ATS Compatibility: SoftStartUp is weatherproof, portable, and easy to use with multiple compatible RVs or in different locations. Includes a free 30-amp power adapter for added flexibility. Please note: SoftStartUp does not work with an Auto Transfer Switch (ATS).

    • Yes, you need this - it makes a real difference
My Coleman Mach A/C hit like a hammer on my 4500W inverter generator. The generator had enough running power, but the massive startup surge caused a brief "blip" that reset my sensitive Starlink and smart TV every single time. After plugging in the SoftStartUp, the difference is night and day. No more roof creaking from the violent kick-on. My A/C starts smooth and quiet. My Starlink works too. Worth the cost and effort. Highly recommended. ... show more

    • Buyers beware
Didn’t get a chance to try it until after the return window had closed. It did not work as described. generator surge and kicked the breaker. air conditions to short cycle. Wish I could get my money back.

    • Highly Recommended AC Soft Start
Highly recommend this product for RV’s. No more hard starts with compressor noise with AC start up and drastically reduced my electric bill.

    • It works!
Works as advertise. Now I can run my microwave together with the AC.

    • Is not as good as advertised in my 50am RV.
Buyer beware, I tried to use it on a 50 amp service and when you turn on the first colman Mac air you can hear the transfer switch drop out and it repeated a few times before it would run smooth. Added the second of three and it sounds even worse. I removed the box and it has no issue running all three on the 50 amp. I tried a 30 amp with one and same issues showed back up. I am not sure if the person who stated it doesn't work well on the two 120 volt legs, but it is an issue that I don't want to fry one of my air units. ... show more

    • WOW— big drop in inrush current!
Used it on my 2024 fifth wheel’s front low-profile Furrion 13k AC - not the Cube. Before: every compressor start slammed the roof with a loud “thud” and pulled over 33A inrush—making dual-AC use on 30A service nearly impossible. After plugging in the SSUP, super-smooth, quiet startup with less inrush. No more waking up to the thud. Excited for hot-weather camping without the noise or power ... show more

Seems to work fine. I use on my rv. Only difference is slight hesitation in microwave

    • Save your money
It may work on a 30 amp pole. But it definitely does not work on inverter/generator. My is a Westinghouse 5000 and it made my generator almost stop just turning on one a/c. Too late for me to send back to Amazon. But I’m with in 90 days from sortstart warranty. Went through steps by email and they said you got it from Amazon so pretty much sorry for your luck. ... show more
