Why Coleman Mach Soft Start Kit Is Necessary
I found the Coleman Mach Soft Start Kit necessary because it makes starting the air conditioner much easier on my RV’s electrical system. Without it, the AC can pull a big surge of power when it kicks on, which can trip breakers or overload a small generator. With the soft start kit, that startup is smoother and more controlled, so I have fewer power issues.
I also like that it helps protect my equipment. That hard startup stress can wear on the compressor and other components over time, but the soft start reduces that strain. For me, that means better long-term reliability and less worry about costly repairs.
Another big reason I consider it necessary is convenience. I can run my Coleman Mach AC in situations where I normally might not be able to, like on a smaller generator or limited shore power. It gives me more flexibility and peace of mind, especially when I’m traveling or camping in places with weaker power sources.
