When using those larger generators on 120v, they are limited to the same 15amp as this smaller unit, although are less efficient due to the size of the motor.
I found the Sportsman brand and after researching, waited patiently until a great memorial day sale came around for HD. I picked up a solo unit, and a package unit (2 generators and a parallel kit) for slightly more than I would have paid for the Champion 3100/3400 (now Champion sells a 2000w version).
I picked up and unboxed all 3 at the same time for observation and breakdown. Upon initial comparison, each generator had varying levels of tolerances between the chasis/frame and side panels, none of them looked identical upon extremely close inspection. One unit had a fairly damaged box and there was a gash in the side panel fairing but nothing major.
One note, I have only run these on propane and only plan to use propane unless in an emergency situation. Propane burns cleanly and does not gum up the engine. Starting the engine with propane will take anywhere from 8-10 pulls to clear the air from the propane line and "prime" the engine. The choke is unnecessary for propane but will not inhibit starting the unit. To reduce the number of pulls, you can start the threads of the propane line and then open the tank up to fill the line with propane and push out most of the air.
That being said, the unit has a feather light pull and recoil. A gentle and patient 8-10 pulls with fire it up every time with propane.
I purchased a magnetic dipstick and ran a fairly rigorous break in for each unit. I started with conventional oil and ran the generator for 20 minutes with no load, varying between economy and standard. At the 20 minute mark, I brought on approximately 200w on standard mode for 5 minutes, cycled off for 5 minutes, cycled on for 5 in economy/cycled off. At the 40 minute mark, I repeated this step but brought the wattage up to nearly 800w. For minutes 50-60 I let it run on econ/standard with no load.
I changed the oil after 1 hour. The oil was black, and there were significant metal shavings accumulated on the dipstick.
I switched to synthetic oil and used an additive (magic marvel oil) to aid in cleaning the engine. For 1-2 I repeated the above process but increased the wattage up to 1500w. I repeated this process for a total of 4 oil changes, for each unit. The final oil change was once the oil was no longer tinting black after 1 hour of use, and only full synthetic was put back in (no additive).
Was this overkill? Probably. However, it is proper engine break in to perform and I wanted to eliminate any concerns down the line with issues engine interference or failure.
THE BAD (let's get it out of the way first):
Much like the appearance of all 3 units not being the same; none of the units sound identical. Each unit has their own unique sound, or rather, rattle. I attribute this to the side panels not fitting perfectly and rattling in some form or fashion. I took the side panels completely off one unit and the rattles were lessened, but the engine noise was also not muffled and could have masked some of the rattles as well. At some point, I will take the panels off all units and tighten all screws and connections between engine and chassis/frame.
Also, the plastic faring on the side panels and front of the unit is very soft. If you are someone who cares that your tools look like they just came out of the box, these units will drive you crazy. For me, I don't mind that my tools look used.
THE GOOD:
PERFORMANCE - These units handled 1900w on propane without the overload sensor coming on. I threw everything from shop vacuums, air compressor, a rug doctor, space heaters, and the surge was not strong enough to overpower the unit (I did not hook these all up at once, obviously). The light did come on when starting the rug doctor but only briefly while the unit spun up to handle the load.
EFFICIENCY - Using a 20lb propane tank, I am continually amazed at just how efficient these units are. A 20 lb tank should easily cover you for a weekend of outdoor activities, or easily a days worth of heavy use at a job site.
NOISE - Even with the random rattles, the units are nearly as quiet as a Honda or Yamaha. That does not mean, "refined" as a Honda motor purrs, but as far as decibels are concerned - they are not much louder.
DUAL FUEL/PROPANE - Again, I cannot recommend propane enough. It is a solid feature to have the on-board fuel tank in case of an extreme emergency but I do not plan to ever use it. I understand why they do not, but it would be nice to see a straight propane offering in a compact design that eliminates the on-board fuel tank.
OVERALL - If you're enamored with name brands, or you're dead set on a Honda generator, skip the Sportsman as you will find fault in the fit and finish tolerances, rattles, and soft plastics. BUT, if you're in the market for a 15A/120V inverter generator for less than half of a Honda or Yamaha - you simply cannot beat the Sportsman.
