A 20lb bottle will net 15 hours, and a 30lb bottle about 24 hours. the refill bottles at Walmart and etc aren't filled to the full capacity. Get your own bottles and have them filled at your local propane filling station.

Or you can just buy a Costco gift card which will let you in without membership just to use the GC.

Yes, if your local store has limited stock it is best to buy now and just bring the receipt to the CSR when it is on sale for price adjust, i have done many time... although I have not try to buy only and price match instore
Both my local stores show them as out of stock, but I called them and they both have 10-12 in stock. I think it's in my best interest to grab one now if I plan on getting one for $600, as I would imagine they would be OOS by the 9th if they only have 10 of them. I think it's worth the hassle!

NOTE: these are modified sine wave generators, not pure.
What? These produce pure sine wave. Where does it say that it is modified sine wave?

Looks to be only 120v from what their website states. I think you would need to go bigger to get 220v.

From all the research I have done, this is indeed a "pure sine wave" and that's why these cost more and produce less power per dollar paid. The standard generator is what would cause issues for delicate electronics, but this should work great. The article below is a good read for the differences between the two.

Quote from Ductyl :
I've read elsewhere that some of these dual fuel generators need to be run on gasoline for a few hours to help set the o-rings (I think the run hotter on gasoline than propane?) it sounds like you did try gasoline, but I wanted to leave the message here for others. Interesting that your Champion didn't need gas at. all, I wonder if they set the o-rings at the factory as part of the QC
That's interesting, I have not heard that. I wonder if it was in the instructions from firman and I just missed it? Oh well…

Yes all of these closed frame inverter generators produce pure sine wave.

This is just another example of someone talking out of their a$$ and spouting wrong information.

Just wanted to let people know that I purchased one of these today and it started on the first crank of the electric start, via propane. The unit is a LOT quieter than I had thought it would be, cause I recently sold my Ai-Power gasoline inverter and it definitely seemed louder and didn't produce as much output either. This product seem very well built and comes with everything you will need, including a cover! Very impressed so far, so buy with confidence. 👍

There are no instructions about connecting (2) of them together at all, but it does have connections to do so. I am assuming that if you look at the parallel adapter instructions online that it may tell you about that, but I have no idea.

Search firman 1201 it is a parallel kit runs about 100$ and gives you a 220 50 and a 30 amp receptacle. Be sure it is the 50/30 as there is a kit without the 50.

The parallel kits make it higher amp 120v not 220v from what I can see.

Would it be reasonable to install a transfer switch at my house and use this generator for the occasional power outage? I understand that I won't be able to go crazy with the appliances and all, but what about to run 2 gas furnaces, refrigerator, TV, some lights, and a few other small appliances/electronics?

I'm thinking this would be too small to run the AC, right?

Most, if not all, inverter generators in this size range do not provide 220V/240V output. There are some larger units do, but they are a lot more expensive.

Parallel cable would synchronize the inverter generators to increase current but not voltage. You can make your own cable too.
