Easy to FIY install, great support if any questions.
Was easy to install on 12 year old Dometic AC units. Worked great on both units. Only one issue- compressor on one ac was drawing normal 12-13 amps before install and 17 amps after. Removing easy start unit didn't change amp draw, still high. Reinstalled the Easy-Start and amp draw remained high. Possible the compressor is about to fail. Fortunately itโs simple to remove the Easy-Start and reinstall on a new unit, but in the meantime that AC seems to be running well. Later followup - problem solved - the run capacitor on that AC unit had failed. Replcaed the capacitor and all is well !! running at 14 amps as expected. Should have checked the run capacitor as part of the process to install the Easy Start !

Buy it and install it yourself! You need this!
Worked great. I installed it myself as it was not difficult. I now can bring a smaller generator. Iโm very happy with this product. It comes with everything you need. I would buy it again.

Super easy install
Super easy install!! They have a great video on YouTube. Keeps my generator from stalling out when the AC comes on now.

Great product with immediate and awesome customer service
Awesome product for my 30 amp RV. Prior to installation, my generator/inverter would shut down when the a/c turned on. My a/c unit would also throw the breaker when I plugged it into the house 120v-20amp outlet. We have no problems whatsoever now. Works as advertised. Easy starts and reduced amperage usage. We did have to call customer service for assistance because not every a/c unit is the same. That assistance was exceptional. Because I was hesitant to make a mistake, the service rep even used FaceTime and gave us step by step instructions to help during the installation. We appreciated the personal attention given to make sure we were able to use their product. Very happy with the product and will add one of these for each of our home units.

Worth the money!
Bought this and installed on my fifth wheel air conditioner so I could run it off my Honda 3200 generator without the startup spike. Came with installation instructions that were fairly easy to follow and got everything installed and up and running fairly quickly within about an hour. So far, works as promised with no issues and Iโm pretty happy with the results. I wasnโt sure if the results would be worth the price especially since there are cheaper knock off versions, but feels like one of those things youโre only gonna buy once and product seems very well built.

It works very well
I can run my rooftop air conditioner 15,000 BTU with a 2000 W Honda generator. And itโs not difficult to install. I would recommend this highly to anyone.

Great unit but so extensive homework
Product works great on our boat CruisAir unit. The reason for a 4 star is the directions or should I say the lack of clear instructions on how to install. What should have taken maybe an hour, took 4 hours. The unit is great and worth buying but be better prepare them you think.
