Real World Performance! - EDIT: I installed this item one week ago today. It has worked as advertised. While returning from running errands this morning I received a notification on my phone that the power was out at the house. The first real world opportunity to see if this piece of kit is worthy of the cheddar. I arrived home in about 10 minutes and confirmed much of the neighborhood was out. It's hot, DAMNED HOT, outside today and this will never do! It took about 15 minutes total time to get the gennie up and running and arrive at the moment of truth. I flipped the breaker for the gennie and powered the panel, then energized the furnace circuit (Ecobee thermostat controls), then energized the A/C circuit and waited. It took right at 2 minutes for the Ecobee to come online (wifi is on UPS) and call for cool. The fan on the A/C started first, seconds later the compressor started, the gennie shouldered the load like a CHAMP, and the A/C was running! I energized the rest of the circuits according to my emergency power plan and monitored cycle performance in cool air conditioned comfort. "I love it when a plan comes together!", Colonel John "Hannibal" Smith. Purchase with confidence! OE Review... Meets and exceeds expectations. Simple, straightforward four wire installation. Easy enough for a handy DIYer. They even have a short YouTube instruction video! I purchased this so I could have AC when the power goes out. I have a 4 ton HVAC that drew 106a inrush before installation. Too much for a modest portable generator in a power outage. After 6 learning cycles it only pulls 26.xxa! A bona fide 75% reduction in startup draw! It’s also much quieter now too. I highly recommend! ## Features - ADVANCED MICROAIR TECHNOLOGY WITH INSTALLATION KIT: Micro-Air EasyStart Flex is the most advanced and versatile soft starter, designed for all sizes of residential AC units up to 6 tons (72,000 BTUs).

Installing it took less than 10 minutes after watching Hutch Mountains install video, and my air conditioner starts up so much smoother now! I am currently running most of my house off of 3 Ecoflow delta pro ultras and about 15kw worth of solar panels. With this unit I was finally able to move my A/C system over to solar power. My air conditioner initially required almost 120a to start up which was overloading all three of those units. I found that the start/run capacitor in the unit had started failing. I replaced that and it dropped the startup down to around 60a. This Soft Start system cut that even further down to about 18a. With this unit you could actually use a generator to power your home AC if needed. It also features a bluetooth diagnostic system to let you know if something is wrong with the unit during startup. I've noticed that my running wattage is about the same (maybe slightly less), but starting surge is about 1/3 of what it was. So I would think this should cut a little bit out of my power bill. It is a little on the expensive side, but for something that is made in the US (and made with high quality components, it has nippon capacitors installed in it!), I was willing to spend a little more. It is also a fairly small unit that is weather sealed. It will mount just about anywhere with the included double sided tape, or you can repurpose the panel screws that covers the relay/capacitors on the unit like I did. The front cover is clear plastic, which allows you to see the internal status LED's for a quick check to see what the unit is doing. ## Frequently Bought Together - MICRO-AIR EasyStart FLEX 398 - Bluetooth Soft Start Kit for Home Air Conditioner, RV & Commercial Use, Works with Generators, Reduces Power Surge, Efficient Start-Up - Up to 6 Tons w/Installation Kit - Amlits 300 PCS Insulated Wire Electrical Connectors - Butt, Ring, Spade, Quick Disconnect - Crimp Terminals Connectors Assortment Kit - Klein Tools 3005CR Wire Crimper Tool, Ratcheting Insulated Terminal Crimper for 10 to 22 AWG Wire --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ie/products/672472995-micro-air-easy-start-flex-soft-starter-w-installation-kit](https://www.desertcart.ie/products/672472995-micro-air-easy-start-flex-soft-starter-w-installation-kit) --- *Product available on Desertcart Ireland* *Store origin: IE* *Last updated: 2026-05-03*
