The Micro Air typically reduces the 55-65a inrush/LRA current found on a typical 13.5 BTU RV a/c as much as 35-45a (down to 20-25a), sometimes even lower. This is a dramatic, 50-75% reduction in inrush/LRA current.
I have been watching this for some time. It would be nice to see some actual LRA numbers for the Coleman "soft start" vs no soft start. I suspect if they were impressive numbers that Coleman would publish them. I do not see them anyplace unless I am missing something?
A hard/soft start cap kit *may* net you a small 2-4a (<5%) reduction in inrush/LRA current. If you have a generator that's right on the edge of starting your a/c, a hard/soft cap kit can nudge your generator into successfully starting your a/c compressor. However, as soon as ambient temps rise (along with your inrush/LRA current) you may find your generator unable to start the a/c again.
Bottom line, the Micro Air Easy Start dramatically outperforms any hard/soft start cap kit.
