Re: How to run a ResMed AirMini on a USB power bank

Where did you find the cable for the AirMini? All of the OP's original links are dead. It seems impossible to find those cables online anymore. I'm also curious as to why you and OP are talking about 20v batteries. Doesn't the AirMIni require a 24v input? Here's a current vendor for the cable: http...

Re: How to run a ResMed AirMini on a USB power bank

I can't 100% sure. But the white cable with "the most popular" DC port jacket (5.5 x 2.1 mm) that can plug and play to Omni Mobile battery. The black one from P__t 24 seems use smaller diameter head. I'm using the black cable with a 5.5 x 2.5mm jack in the power supply I built, no adapter needed.

Re: How to run a ResMed AirMini on a USB power bank

If you want even cheaper one, this website (https://lofta.com/products/airmini-pilot-battery-cable/?variant=9721633341487) selling for only $19. It is actually the same cable come with P__T 24 ( black color). But they are temporary out of stock. Moreover, their DC end is not the most popular 5.5x2....

Re: How to run a ResMed AirMini on a USB power bank

That may work for you, but that device can draw, at max, 27 watts, and few power banks can deliver THAT kind of power for long, and you're risking a fire if you draw that for any length of time. The average power consumption of the AirMin is spec'd at 6.3W, considerably less than the 27W peak ratin...

Re: How to run a ResMed AirMini on a USB power bank

I've just returned from a European trip, where I brought my AirMini and the home-made power supply. I carried the power supply in the same travel bag as the AirMini. It did not attract the attention of the TSA nor the airport personnel in several European airports. I wasn't sure I'd actually need th...

Re: How to run a ResMed AirMini on a USB power bank

Finally, I finished the project. Here are pictures of the front and back of the enclosure. The enclosure is much bigger than needed. I might build a new, smaller one at some point, but this works for now. The scuffing on the front is the result of me removing some nail polish that smeared. I decided...

Re: Fixing AirMini drawstring bag

Anyone know how to re-attach those bits? I fixed it! I used a knife to pry open the plastic nut. There's a hole in the nut where the two pieces of cord come in, that's where I stuck the knife, the other end is hinged. I used an unwound metal hanger and some Scotch tape to push the cord through the ...

Re: Choosing a Battery

You need a voltmeter, and the specs for your machine, also some machines use three wires not two. Jim The device expects 24 VDC which, yes, I can measure with a multimeter. The only unresolved question is the polarity of the input to the 5.5x2.5mm plug. It's likely center-positive, which is much mo...

could the "nut" be a spring loaded slider that holds the string tight when released?
No, it seems to be fixed in place.

The cable wiring should match what you are using it on.
Indeed, it should. I'm using a cable with a different source, so I want to know what input the cable expects.

Re: Choosing a Battery

I've asked elsewhere, but got no reply. So I'll ask in this thread: what is the polarity of the DC output of the Medistrom Pilot-24 Lite? Is it center-positive, or center-negative?

Re: Fixing AirMini drawstring bag

You're asking how to thread a drawstring through the bag? No, I'm not. There's a black plastic nut that's become detached from the string. It looks like it opens, somehow, but I don't want to break it. The nut on the other side is still attached. There's also a piece of string that was somehow thre...

Fixing AirMini drawstring bag

Today I acquired a ResMed AirMini for travel this summer. I put the unit, power supply, and hose in the provided bag, and gave the drawstring a good tug. Oops, one of the black plastic nuts on the drawstring fell off, and a piece of string came off the bag completely. Anyone know how to re-attach th...
