Firman 2900W Running / 3200W Peak Electric Start Gasoline or Propane Fuel Powered Inverter Generator Gas and LP $629.99
$629.99
$779.99
Costco has this dual fuel inverter generator $150 off (valid til 21-Jan) with free shipping. Things I like about this:
1. Dual fuel - running mine on propane so it's clean and I don't have to worry about stale gas when I store it
2. Electric start
3. Costco 3 year warranty
The only negative for me was the noise but it didn't seem so bad in the youtube review.

2900/3200W when running on gas, 2600/2900W when running on propane.
The rated 9 hour runtime on gas is at 1/4 load (2900 / 4 = 725W) when in eco mode. Running higher loads will throttle up the engine and reduce run time.
Cannot use gas with more than 10% ethanol, also recommend the use of fuel stabilizers.
It is to me. I hate storing all that gas, since it goes bad so quickly. Propane does not go bad.
I think it ultimately depends on your preference. Is it worth an extra $130 to you?
Personally, I find gas to be more convenient and readily available than propane. I only use propane for my gas grill. I currently buy gas for my small engines (snowblower, lawnmower, weed whacker, etc) so it's already necessary to store gas.
I've had portable generators for 14 years and have never had issues with gas gumming up my carburetors in generators or small engines.
1) I always use fuel stabilizers. I used to use Sta-bil but recently switched to Star Tron enzyme gas treatment based on overall reviews.
2) My generators and lawnmower have a fuel shut off valve. I always shut it off and let it run *dry*. I know there's some fuel left in the bowl but in my experience, this hasn't caused any gumming problems when used with stabilizers. Knock on wood, I've had engines that have never need a carb tune up even after 15 years.
3) I switched to ethanol free gas which even though it costs more, it avoids the risk of gumming up that is associated with ethanol blend gas. Probably Overkill but I do add stabilizers to it as well. You can find ethanol free gas stations at www.pure-gas.org
Living in Michigan, I use gas year round for lawn equipment or snowblowing and gas will sit in the tank of my lawn/snow equipment for 5 - 8 months with no problems.
For my needs, I have three 5 gallon gas cans and typically have between 10-15 gallons available for emergencies at any given time, all are treated with stabilizers.
- two 5 gallon cans to store ethanol free gas (typically exhausted in 12-18 months). Refilled when any can runs empty.
- one 5 gallon can with regular ethanol 10% blend solely for extended emergencies. The gas is cycled yearly by dumping it in my car's gas tank and replacing with fresh gas.
I have two Champion inverter generators 1600/2000W through a previous SD, used for emergency backup. House is wired up with a generator interlock kit and a 30A power inlet so that I can power my furnace, lights, fan, fridge, freezer and even run laundry. I have the parallel kit and run it in single or parallel based on load requirements. I like the redundancy of two smaller units (in case one won't start). It's nice to have one running and another on standby so I just need to switch generators instead of refueling a hot generator (especially when it runs out of gas in the middle of the night). Also love the portability as the smaller units weigh around 45 lbs and can be stored on a shelf instead of on the floor, also portable for camping, etc.
I've already put them to the test, last outage was for 3.5 days due to bad storms and my combined generator use of approximately 60 hours burned through 10 gallons of gas. I feel that having enough gas to last over 3 days is pretty comfortable and in a pinch, I can always siphon gas out of my car or get more gas if any nearby stations have power and are open.
If you use stabilizers, gas will easily last up to 2 years. Not using stabilizers and using ethanol blend gas is what gums up your carb.

I did watch it, I think noise is somewhat subjective because it depends on what you're expecting. This Firman's "quietest" is as loud as the "loudest" of benchmark portable inverter generators.
This Firman is 58 dB at 25% load (725W) but doesn't mention how loud it is at higher loads, I'm going to guess that it's closer to 65 dB at full load since Champion has a similar sized inverter generator with a similar dB rating.
Honda and Yamaha make arguably the quietest inverter generators but they're pricey. A Honda EU2000i (1600/2000W) is 53 dB (1/4 load) - 59 dB (full load). The larger EU3000i (2800/3000W) is 50 dB (1/4 load) - 57 dB (max load). If you've seen and heard these in person, then use those as your reference.
My Champion 100565 (1600/2000W) is 53 dB at 25% load (400W) and probably closer to 59-60 dB at full load (1600W) by my best guesstimate. Subjectively, I would have no issues standing 3' away and having a conversation with someone when it's running or camping adjacent to a site with it when at 1/4 load (53 dB) but wouldn't appreciate being stuck to one overnight when running at full load (59 - 60 dB). Angling the exhaust away from people certainly directs the sound away but it's still going to be audible. Running two in parallel won't double the noise but probably increase it by around 3 dB.
So that said, the Firman is still going to be loud if you are restricted by the noise level. However, it is going to be quieter than a standard open frame non inverter generator that can easily be 65 - 75 dB which would irritate even the deaf.
Remember dB is logarithmic.
A 3 dB increase is about 25% louder, 6 dB is about 50% louder and 10 dB is about twice as loud.
So depending on how much you're loading it and how much it gets to idle or rev up will dictate how loud it'll be for your use.
