I wonder if someone else who owns a Duromax / Durostar 4400(E) could clarify something for me though... When I plug this into my generator (Durostar 4400E) on 120v mode, only one side of the adapter lights up. There's nothing wrong with this adapter, I checked it and the generator with my meter. I notice that of the two 120v legs on the generator plug, only one of them is a closed circuit in 120v mode. When I switch it to 120/240v mode, both legs have a closed circuit.
So my question is... Which way am I getting the "full" 120v 30a capacity of the generator? If I run it in 120 only, and only one side of the connector has power, does this mean both windings of the generator are engaged and I can theoretically run 30a (realistically 20a) from that one plug without tripping the breaker? And when in 120/240 mode I have one winding per adapter end so 15a each (and should balance the load)? I just don't want to screw something up, none of this seems to be well documented.

Is it unfair that you have to buy this somewhat (~$25) expensive (but very sturdy) "cord" to fully utilize your generator that you paid so much for in the first place ? Maybe so....but at least it solves the problem easily! You can check your generator's owner manual to see if all the 120V outlets are attached to only one winding. Some more expensive units may have 120V outlets on both windings. However, I have a fairly expensive Yamaha 6600, and all my 120V outlets are on one winding / one breaker. I had built a homemade cord to perform the same function, but this item looks more professional and is more sturdy. Spread the word to your friends and neighbors who may have bought themselves a nice generator, but may not be utilizing it to the fullest extent, or are facing damage by overworking just one of the windings.
I don't use it anymore as I had an electrician hooked up the generator to the electrical panel. However, I still the cable just in case it's needed again... Like if I need to use the generator for loads outside the house. Or if a relative borrows my generator.
