2016年7月15日 · The gist is that you hook a battery (or 2 for 24 V models) directly to the CPAP. Virtually all CPAPs these days actually run on 12-24 VDC, derived from the AC power line by a power supply module. If you can bypass the module, you can run much, much more efficiently from a variety of 12VDC sources without using an inverter.

2023年10月7日 · Other than the battery being obtained from a local auto parts store, all the rest were purchased from Amazon. The power supply is a KFD 12V 24V Car Charger Vehicle Power Supply 90W and is $30 USD. I've had real good luck using this brand of power supply. If you notice, the type of battery I chose has threaded terminals.

2017年10月3日 · But a second battery can be added to double that run time. The two batteries plus a cable to connect them will cost about $1200. However, it really can NOT be used as a backup power supply. In other words, you can use your normal ResMed power supply OR the backup battery (or, batteries as the case may be).

2021年10月17日 · Most important of those accessories is figuring out a battery backup for the Airsense. I have a Maxoak that's worked very well with my Philips CPAP, running for four nights if necessary on a single charge. But the Airsense 11 has a new gnarly proprietary (I'm guessing) DC power port that won't accept any of the power adapters with my battery ...

2024年9月24日 · They have one for the Airsense 10 and it comes with the proper cable so if you kept your Airsense 10, you can get the battery backup for power outages. The two things to keep in mind are: 1) Is the pressure the same or close between the two CPAP machines 2) The battery backup for the Airsense 10 is $300.

2023年1月18日 · I just got a airmini dc/dc converter # 38839 for $100usd shipped to canada and I plugged it into my cpap powerbox that has a brand new renogy 50ah 24v battery. I have a cig socket thats regulated with a buck converter to give out only 24.3v instead of the batteries 27v fully charged state.

2023年9月4日 · Make sure to test the Freedom 2 as a battery. (unplug it from wall and see if it will power your cpap). I bought one two years ago and used it as a ups. Worked fine to pass power through to my (ResMed) cpap. Had the first power outage a few weeks ago and found that the battery didn't work! It's supposed to switch to powering the unit if no wall ...

2021年10月18日 · If if looks just like the 12V AirMini DC-DC adapter, then this would be your battery backup solution during a power outage. You could plug this into any 12V accessory outlet on your backup battery and run the unit on DC power. The original AirMini AC adapter will not physically fit into the Airsense because of the way the receptacle is shaped.

2022年1月24日 · RE: ResMed Airsense 11 battery backup (01-24-2022, 08:43 AM) wiredupjax Wrote: I can only assume better with the DC adapter. From my tests, you can expect perhaps 8-10% more runtime using the DC/DC adapter, versus using an Inverter and AC/DC converter, given the same battery source.

2022年3月17日 · I’ve attached a screenshot of what I found for a battery backup. It uses a battery and an inverter that you plug your machine into. Not cheap by any means but it would work. Looks to me like it would work to hook the inverter into a 12 volt battery plug on a car or camper (Which is where I use the battery the most). Hope this is of help.
