Would this run a 400 watt oxygen concentrator? If so how long?

Based upon a claimed 1250 Watt Hour capacity, barely three hours on a full charge.

James these cabs are only rated for 30 watts each so I don't think running a 400 watt head threw them would work very well but I am not positive.

All it requires is an outlet, mine runs 365/24 until it stops. My is in a 15 or 16 gal so it would be fine.

it needs to have about 2400psi up to 3300 max,,, also your gallons per minute need to be over 2.2 at least, for this to work the way it needs to

I had to take a look at the timer to answer. The rating on it is 15 amp, 1800 watt. So as long as you fall below those max ratings on the timer you should be ok. I bought it because it was the only basic timer I could find with this high of a watt and amp rating that would control a 1.5 HP pool pump, all the others had too low of a wattage and amperage rating. I am satisfied with this timer, its basic, affordable and will power larger items. I had a really fancy digital timer I paid 4 times more than this one for and the electronics in it went bad. I like the simplicity of this one without any electronics that can go bad again.

This has to be attached to a battery source (like a car battery). It would depend on how many watts is required to run the CPAP machine. I can't imagine it would be greater than this, but you would have to check what is the minimum wattage to run the machine. This is an 800Watt. There are 1000 Watt and 1200 Watt ones as well.

Mine will run a small 700 watt air unit in my shop just fine and it ran my old refrigerator just fine but it will not run the new energy star fridge. The new fridge would not even try to turn on. I guess it looks at the input to see if it is good and gave this inverter a fail.

This unit has about a 1620 watt draw. I have a 5000 one and it works great matatically it shout work when running. The problem u may run into is the start up wattage. Many a/c unit can go about 4 times higher to start up the unit which would be around 6400 watts. My inverter has a 10k start up and it fires it up. I would guess u will have less than a 50-50 shot the generator will fire it up. If is can then your generator will give it the power it needs

No, the manufacturers use several methods to artificially inflate the numbers. For instance running the tests at 16.6v in a system that won't be strained to run 4000 watts. In a real world scenario you'd be lucky to see this put out 2k watts @ 1 ohm stable. But for this money, you're not going to find much else putting that kind of power out.

400 watts is about right. it takes a while to come up to full temp but you can use the propane to speed up the process. I leave mine on full time. always have hot water.

Not sure - if it says it needs 350 watts then it probably does to run effectively or maybe even at all - I've used it with 400 watt and 550 watt power supplies and I know it works great with both of those... RH

Very difficult to find specs on these machines before buying, still waiting for mine to arrive but have seen somewhere indicating about a 5 amp draw... so that would make it around the 550 to 600 watt range.

It really depends on the amount of current draw, but I can tell you that generally you are going to get about 10-15 minutes of runtime from this unit on a standard computer. A gas generator is the only low cost option that will give you 3 days.

I doubt it will work at all. After about an hour of use it started to have problems sustaining a load for 350W, by the next morning, it was dead. Amazon gave me a full refund.

Any generator that is at least 1000 watts will operate this unit. We suggest getting on a little bigger incase you want to run something else.

Yes, it is a 3000 watt supply. It would take exactly half the power of the unit. Furthermore, there is a meter indicating how high the power that you are using from the unit as a safety if I am not mistaken. I use it to power a humidifier, air purifier, playstation 4, tv, and a computer at the same time. It is worth the money.

The most powerful R/V units could pull 2000 watts when cooling, 1800 when heating. It should run that and the refrigerator and a small TV, so it depends on what else you have to power for these it should be OK.
