So you have TWO units ??

What I was referring to is a unit that runs internally on 12 V AND has a 12 V "brick" instead of a 24 V one.

Those can be used pretty much everywhere and the "extra" 12 V cord you need, that probably doesn't come with it, is inexpensive or easy to make yourself.

I asked for the 12 V type right up front.
They sent the wrong one.....but were quick to admit the mistake and exchange it for the right one.

No... One CPAP unit, but two "bricks". One of them is the original AC adapter. The "brick" that I purchased for travel has a cigarette lighter plug (and an adapter that terminates with alligator clamps for direct battery connection). It can operate off 12v or 24v input.

I bought the ResMed 12/24v "brick" because I'd rather spend $85.00 on a part that comes directly from the manufacturer and is guaranteed to work than take a chance that my dirty old Chinese inverter would damage the circuitry in my $1,300.00 CPAP.
