Power connector for Airsense 10 Autoset?

[Kingsway]

Hi everyone,

Just wondering if anyone knows what DC connector is used for the Airsense 10 ? (I'm hoping to make up supply for running off battery)

Thanks - Yes, I saw those - but I could use my 24v Li on battery pack for my Disability scooter.

(Should keep it running for a week or two!) So all I really need is a connector and a bit of flex.

I don't recognise the connecor at all - I wonder if they've been 'clever' and used a proprietary one of their own design?

ResMed has always been notorious for going proprietary and not the least bit interested in cost savings.
There are some products on Amazon that say they will work for about 1/3 the cost.
Do they??? Or how well??? I dunno. I have never used a battery or needed to for that matter.

I believe:

• Connector is a (5.5 x 2.1mm barrel connector(DC7406??)
• Inner sense pin +3.3vdc
• Inner cylinder +24vdc
• Outer cylinder Ground

I ended up ordering one of these https://www.amazon.co.uk/KFD-Vehicle-Ch ... 77&sr=8-1 - not too expensive, and seems good quality and works well - on both 12v and 24 DC! Good for use in a vehicle or aircraft even.

I'm spending a few weeks in Cape Town later in the year, and our host has a small battery-powered backup system to carry over the constant power outages they have these days, due to the breakdown of public infrastructure ( mass corruption and siphoning off of government funds, apparently! )

Thought it might be good to not need to do a double conversion with an inverter up to 240v and then a 'wall-wart' back down to 24v dc
