WEN Dual Fuel Portable Generator 4750-Watt

I purchased this generator primarily for its dual fuel capability and the claimed power output. My specific needs were around 1500 watts for my compressor and a few hundred watts for LED lighting at my construction site. Upon receiving the package, there was minimal external damage, but unfortunately, the generator itself had a broken motor stand (pic 1) and was missing the ignition keys. According to Wen support, the generator couldn't be used without the keys, potentially causing a three to five-day setback at the job site. Frustratingly, I expected the generator to be functional upon arrival, especially since we're not connected to grid power yet. Fortunately, I found a workaround from another manufacturer's guide, allowing me to start the generator without the keys. This involved disconnecting two cables to use the pull starter on propane, but it didn't seem to work with gasoline. Dealing with Wen's support was a letdown, as their tone was short and condescending over the phone. Additionally, the lack of instructions for replacing the motor stand surprised me. While I have mechanical experience, the process of dismantling and installing the new part took me at least an hour, and I had to use a steering wheel puller to remove the motor stand and a screwdriver to pry off the cover plate, resulting in cosmetic damage. There are a lot of wires in there and bolts to remove (pic 2). It seems unreasonable to expect the average buyer to address such issues on their own, especially if they have to hire a mechanic for assistance. If a company claims a "nationwide network of technicians," they should provide more substantial support. The electric start function works well, and the generator runs smoothly on propane. However, it struggles with higher settings on my 110v and 240v welders and my compressor, making me question its power ratings. Notably, the voltage drops significantly under a high load, raising concerns about its consistency. I've observed this under both propane and gasoline fuel types. After approximately 125 hours of use within its limits, mainly on the 240v side connected to my electrical panel, the generator has functioned without issues. However, based on the overall customer experience and the observed performance, I cannot recommend this generator. Considering the price range, there are likely better options from other manufacturers. Perhaps even a manufacturer who has a comprehensive support plan in place to either replace broken units or have them repaired at their expense.
