You can add more gas to keep the generator running for days vs you can run a power station for hours until it need to be recharged with either AC or solar?
Despite what politicians will tell you, gas-powered generators aren't going anywhere. Power stations are fine for short term use, but they will never compete with a gas generator. I have several power stations and have used them to run a microwave during quiet hours at a campsite, but I could never run a microwave longer than 40 minutes before it would need to be recharged. Several months ago in CA, I ran a gas generator for three days when Edison shut the power off because there was a breeze. My power stations were good for running my WiFi router and charging phones, but they would not have been able to run my fridge and freezer for three days.
A gallon of gas has about 36 kilowatt hours of energy in it. If this thing is only 50% efficient that's 18 kwhr. To get near 20 kwhr of battery you'll spend thousands.

If you have room in your budget I'd consider the Firman 3200W dual fuel that's currently $360 on eBay. It's refurbished, but the one I got a year ago was like new. Should be quieter and running on propane eliminates many of the maintenance hassles. Note that it is over twice as heavy though (but rolls easily on wheels)

Legitimate question: Why would I purchase a gas powered over a portable power station of equal wattage?
For $300 you can get a refurbished 768 watt-hour battery and 800 watt inverter and maybe a 100 watt rigid panel.

Nothing comparable to the output of this.

Now the best is to have one of each. Use the generator for quick charging the power station and use the power station at night and to allow the generator to be off between charging runs. This drastically reduces the gas usage in the generators.

How long does gas stay fresh before you need to replace it, also is it better to keep gas in canister instead of generator?
Could anyone give examples of what this capacity generator can run for how long? I assume router and modems, phone chargers are no problem what about fridge, like one of those 3 or 4 cubic foot or maybe hotel size coolers, toaster, can they even run small portable heaters at all?
I was going to get Costco deal which is a much better buy at $700, and it's tri-source, but it's way too big and heavy and too many moving parts but thst should keep many items running much longer. What's the sweet spot between portability and power?
I only fill up the gas tanks closer to hurricane season - or if there's a known threat coming (a week in advance). I keep gas in the canisters for 3 weeks and then empty them into my vehicles. Then wait for the next potential storm.

I keep the generator in Long Term Storage (following the procedures per manufacturer) until it's needed. For now, I won't run it until it's needed as I expect it to be good to go. If I have issues starting it up, I may change my process to "wake it up" at the beginning of the hurricane season and run it every two weeks or once a month.

I've ran a water kettle, sandwich maker, "solar" generator (AKA large battery/inverter), and lights during a camping session.

I've ran internet, tv, ps5, fridge during the day and lights, window AC, and fridge during the night on a power outage at home. In my experience, it uses a gallon every 7-10hrs. Looking at the product feature list, it says 5.5hrs @ 50% load for 1.06 gallons. I guess I was using it closer to 25% based on my calculations.

As I mentioned earlier, the ideal situation will be to have a 200Ah "solar generator" (aka batter/inverter) which would power the internet, fridge, and other peripherals for 2-5 hours which this generator can then charge for 2-3 hours. So instead of running the generator 5-7hrs, you only run it to charge the battery which is 2-3hrs.

That's some setup! It's a neat idea to "chain" these together, and you also manage to earn extra few hours of quiet time with this arrangement Smilie

It's probably going to be 20-30% efficiency. However your point is still perfectly valid and correct.

Electric battery is fantastic, but it's expensive for long period of high power. However no maintenance!

Gas generators are much cheaper, store much more energy and drive bigger loads. However they need maintenance and more hassle (need to run outside the house, loud, need to store/rotate gas/oil)

Umm i bought a power station that wouldn't even hold a charge... i wouldn't call that maintenance free... a battery cycle depends on the battery it uses.. they vary but i definitely wouldn't call it maintenance free... they only last 3-5 years if your lucky

I don't think this is much of a savings off its regular price. The original price is inflated or using Honda equivalent.

You evidently didn't price a Honda version. 2200watt Honda is $1100

That's a great website, thanks for that.
However, one question. Is there a standard when it comes to running wattage in time like when we see a 2500W generator, is there a minimum these are required to run at 2500W consumption like 6 hours at full capacity with a full tank, or can they just run 1 hour because they have smaller tanks.

When I check some generators, for example one will be 5000 W running and spec will say 6 hours at 50% capacity, this means if I have it running at 2500 W consumption, it should run for 6 hours total, right? At full capacity consumption 5000 W (not counting the starting consumption which is a short period except for things like compressor etc) it would only run 3 hours.

Do some generators come with larger gas tanks to run longer even though they might list smaller wattage capacity?

Personally, I don't want to run a generator constantly. I've considered getting one, but weight and size is big, plus carrying a ton of gas. I know it's more equipment, but I'm considering a refurbished Bluetti AC200, I think it was, for $480 and a smaller generator if I need to recharge it, plus solar and my LiFePo4 200Ah battery and I can even charge it on the go if I run for groceries or something else. For my little camper with an AC, microwave and fridge. I want to live out of it, not just in it all the time for a week or two or more. I've been camping from my van or car, mostly. Lots of opportunities to see if it's worth upgrading later.

The B300 is more expensive and only about 300Wh more than another AC200, but over $200 more refurbished. Might be better to buy two, but it is more weight and size. Not a problem if you plan to be sedentary, and if the unit breaks you have a backup instead of a battery that's useless without anything else.

I don't know what politicians say but I can tell you for a fact that a power stations can power your whole house. Depends on how much you want to spend on them. They are 1000 times cleaner and easier to use than a gas powered generator. I have had both. I sold my gas generator and got an Ecoflow with 9000 watts hooked up to my house. I am considering using this little gas generator to recharge those if needed. I generally don't lose power for more than a day though.

My plan was to buy perhaps a larger gen and have a fairly large battery. Then use the gen to charge the battery(so battery would have to support UPS/passthrough). So then you can greatly extend your gen's gas supply. Guess you could also do natural gas but where i live during that huge storm that texas had even states that were not texas got warned natural gas usage had to be cut back so gasoline or propane was the only options. By having a decently sized battery you could charge it in say an hour or two and let most house hold things run off it for a few hours then turn the gen back on rinse and repeat. At least to me it sounded like a good idea but I'm probably missing something in all this tbh.

If your going to go all nutso try to be accurate. It's underaged kids from china, Brazil and Australia that's about 90% of the world supply.

Hate it when dumb people give environmentalists a bad name.

Efficiency???
It's not an air conditioner or a water heater that you are going to run for 10 years. Which would add up to to thousands.

It's about KISS. Put gas in it and go go go. Replace it for $300 and go go go
