Ok, Some CPAP machines run fine on 12 volt Some (epically ones with heaters or humidifiers) do not.. Some models do not have 12 volt ability, some do.. I assume hubby already has one so it's too late to consider all this.
now.. SOME Inverters power outlets near the bed, some do not.. So you need to run a diriveway test. Here is how.
You need one of the following
A test lamp (This can be a trouble lamp, Table lamp, Floor lamp or one of those lamp sockets which plug into the outlet or a night light.
And that's all.. Just the test lamp Even a 3-outlet tester (Which by the way I highly recommend you have for other reasons) or a Kill-A-Watt meter can be used, So can a radio or Fan.
Plug it in and observe if it works.. If it does, Unplug from house power.. IS it still working? IF so, GREAT, that outlet will run Hubby's machine.
If not, find one that is still live... If you can.. IF not. get back with us for more suggestions.
When I went for my sleep study.. They said I did not need one.
Home is where I park it!
