Dreamstation Go portable power solutions

RE: Dreamstation Go portable power solutions
I'd just like things to be as efficient as possible. If I bought this and stuck a molex on the end, is this more or less efficient than an inverter?

Seems like it'd actually be less efficient with claims like these: "Efficiency >50-80%, depending on input, output, and power."

RE: Dreamstation Go portable power solutions
Probably wouldn't be much more efficient than in inverter.

But keep in mind, the problem with using the DC input on the DSGo is that you can't use the Humidifier/heated air. The Firmware disables that with the DC option. That's why I went with the AC option... I can use all the functions.

Honestly, the DSGo is a trainwreck of a device when you consider the DC options available (or not) and if you want to go DC, the DSGo is probably your worst choice possible. I wish I had it to do over again.

RE: Dreamstation Go portable power solutions
It's unfortunate that they did not provide a good DC option. It's unfortunate that they don't even allow passive / unheated humidification. It's also unfortunate that both the machine itself and the battery option contain separate AC-DC converters. It seems like that could have been architected better to avoid carrying redundant weight.

However, I did press the battery into service during a recent power outage, and I was glad to have it. I had tested with an HME for just such an event - not great, but better than nothing. Unfortunately, they're only good for a week once they are opened, and I had not ordered more yet. Oh well. The machine does work well, but it's really optimized for hotel travel, not camping.
