Is also the
Dometec SmartStart but it is pricy.
I have the Easy Start in my camper and have a Sure Start for my 15kbtu test unit but plan to test when under 100 in the garage. Have heard it works well with a typical Coleman and a Predator.
Both work fine but the Sure Start requires one more wire than the Easy Start.
The manuals for both are on line.
I consider one to be essential for running a TM AC on a single lightweight generator.
