Bests & Worsts Reviews from Amazon

The generator was delivered undamaged, despite the fact UPS left the box in my driveway all day in a rain storm (internal plastic and foam packing was sufficient to keep everything dry). I specifically purchased this generator to run on propane, but having the gasoline backup is a nice option. I'm very happy with the generator quality and performance, and I fully recommend the purchase. See below for my detailed review. What's included The generator comes completely assembled, except for the included wheel kit and handles that you need to assemble (and removal of a shipping block mounted under the motor). The kit also includes a couple tools (wrenches, spark plug wrench, screwdriver and funnel with clear tube). The generator has the propane regulator and connecting hose (about 3 ft long) incorporated into the engine, so the hookup is exactly like attaching LP tank to a BBQ grill. Assembly Wheel kit and handles were pretty simple to install- no issues, all hardware was included. One note on assembly- the generator is shipped with the negative battery terminal wire disconnected to prevent the battery from draining, but nothing in the assembly instructions explain you need to reconnect this cable. The negative battery cable is tucked up under the gas tank, so you'll need to dress the wire down to the battery and attach- also simple once you know. I actually called DuraMax technical support because I thought the cable was missing. To their credit, I wasn't on hold that long, and the tech support answered my question quickly and was pleasant- so my experience was good. My battery was nearly fully charged, but I charged it anyway with a battery tender float charger before I attempted start the engine. The generator ships without engine oil (and not included). You need to fill the motor with 20 oz of oil (I used 10w30 motor oil per the manual). Adding oil is a bit tricky because the oil fill is located on the lower side of the engine, but the funnel they included worked perfect, and has a clear plastic tube (about 12 inches long) that fits nicely into the filler opening. Starting and running performance I connected a standard 20lbs LP tank, primed the motor as instructed and it started and ran smoothly. I verified the 120VAC and 240VAC with a multimeter- all was perfect. I also connected a Connteck Y Adapter cable to the 240VAC (takes 240VAC twist lock into two 120VAC, 30A). I plugged in a 500W halogen lamp and let the generator run for about 1 hour, switching between 240VAC and 120VAC receptacles, flipping breaker on/off to verify load. All looks great. One note on the 12V DC output. This is for charging 12V DC batteries. The output actually measures about 20V DC, so if you're planning to run a 12V DC appliance, you could have trouble.
