Air mini dc adapter poorly designed

[Jeanpgene]

I have a lithium computer power supply that will last 5 nights at 8 pressure setting on my resmed 10 for her with no  humidifier using the resmed dc adapter. I wanted something smaller for traveling and camping, so I purchased the AirMi while nosier, with some adapations to the mask, I liked it enough to keep it and purchased the dc adapter for camping. Big mistake. The adapater only allows one night on the battery! Still d and talked to the dme and they called resmed. Apparently this us how it is designed. No more than one night no matter the size of the battery. It is ridiculous, but true.  completely fu

I assume you obtained the Resmed 12V to 24V DC-DC adapter 37297 and not an inverter for AC power?

HWell, yes. That is why I said resmed dc adapter. That I paid $89 for. Not inverter.

I don't know what's happening with your setup, but this just isn't how electricity works. According to the ResMed Battery Guide the AirMini takes about half the power at 20 cwp vs the AirSense 10 AutoSet for example (no heated tube or humidification).

I'm curious exactly which battery you have and the settings you use on the AirMini, but if you search for the ResMed Battery Guide you can see power requirements there and verify your battery is actually big enough.

If all you bought was the power cord/brick (and not a battery) it will run your machine for however long your battery will last, which is a function of it's size (Ah rating). Bigger battery, longer time.
