Thread: Invertor Generator

Has anyone here had any experience at using an inverter generator, one of those small compact models around 800 - 1000 watt mark, to run a CPAP machine?
I ma thinking of getting one to take on a trip to Stewart Island to either run the machine at night while I am sleeping or charge the battery for it daily. As extra batteries are ridiculous prices.

4 stroke for sure

The Honda or Yamaha will be the quietest and the most frugal with fuel

I have used all sorts on hunting trips over the years and those are the two I would trust

I dread to think of the fuel costs on Stewart Is and transporting a quantity of it and what does one do if it breaks down?

@DavidGunn just gone to $3.04 / l for 91..... I think the ferry can only take 60l total on the deck due to h&s with passengers.

The good thing is you will be able to take a leckie blanket to tuck into your sleeping bag and a TV....no point wasting that power.

Only problem with them is the fuel cell usaly only holds enough for about a 4 hour run time. The older type aren't recommended for running electronics

I know a guy with a CPAP machine and he just runs it off a 12v battery while staying away in his camper. Has a solar panel he puts out during the day to charge the battery. Would be a better way of doing it than a generator.

This. A lot of electronics will run on 12 volt, have a look at the CPAP's manual. Hope you work something out.

As NZ32 says: somewhere on the CPAP will be the wattage draw (Google says between 30 and 60 watts). Thats a silly small draw on any generator. You may be better off with a decent deep cycle battery (or lithium, as it will last you forever, and can power a multitude bits of kit around base camp) and a solar panel (decent size)

Buy a Tesla and run it off the cigar lighter, go Honda, but there are a few good, cheaper ones around, Trade Tested isn’t one.

Have a look at one of these, basically a battery with a built in inverter. They have an even bigger one as well. They can be recharged off mains or with a solar panel as well. I use one for charging drone batteries on the go and it works really well. The only noise is the cooling fan comes on intermittently when you're drawing over 200w

One of the reviews for this unit says that they used it for CPAP machine. Used a 1/3 of the charge for one night. You’d only get three nights out of it
