Re: Battery solution for Breas Z2 Auto and HDM Z1 CPAP offgrid (backpacking, camping) usage
Klarity You could try to place a usb-c power meter between the nb20000 powerbank and the usb-c pd 15v trigger cable to verify that pd trigger cable is asking the nb20000 powerbank for the correct 15v voltage? I think Amazon has one for about $12-$14 sold as "MakerHawk Type-C USB Meter Tester Power M...

Re: Battery solution for Breas Z2 Auto and HDM Z1 CPAP offgrid (backpacking, camping) usage
Schnuffelnase I had the same problem with a number of PD wall chargers. Some would drop power after a couple of hours and others would drop power once I turned on Z2 auto cpap for treatment. The only PD wall charger model that I have found so far that provides constant power was this Anker model. A2...

Re: Battery solution for Breas Z2 Auto and HDM Z1 CPAP offgrid (backpacking, camping) usage
Jas88, sorry to hear that you have been having problems. I agree with RobK that it sounds like the zen desk power banks may be having problems. Perhaps try another power bank like Nitecore nb20000 or Anker 26800 power bank I have also experienced random power cycling when running the z1 on a power b...

Re: Battery solution for Breas Z2 Auto and HDM Z1 CPAP offgrid (backpacking, camping) usage
litetrek, I have not seen that power cut out problem using some usb-c powerbanks like the A1376 Anker PowerCore+ 26800, Omni Mobile 25,600, NiteCore NB20000. However I have seen a similar power cut out issue when trying to run the Breas Z2 from wall power using some of the Anker wall chargers, speci...

Re: Battery solution for HDM Z1 CPAP offgrid (backpacking, camping) usage
I have the Omni Mobile 25600 and it does support USB-C output at 15V. I have used it with a usb-c pd trigger cable. You should check the specification pages on the Omni website for the other two Omni power banks you have to verify they support USB-C output at 15V. If they do then you should be good....

blue serotta Here is a list of items I have in my cpap bag when backpacking / thru-hiking. I used this setup for my 6 month thru-hike of the Pacific Crest Trail. Apologies for the delayed reply.

Re: Off grid RVing and the Z1 voltage dilemma
stevenal, great to hear that you found a solution for your z1 using a 12V to 15V car adapter and usb-c power delivery 15v cable.

Re: Battery solution for HDM Z1 CPAP offgrid (backpacking, camping) usage
Update: For 2021 I upgraded my off grid cpap machine from a Z1 to a Z2 Auto CPAP and Nitecore NB20000 batteries. I use the Anker PD1 30w charger to charge the batteries when in town. I can also use the Anker PD1 charger to power the Z2 when in a hotel / motel room with wall power. I have been using ...

Re: Battery solution for HDM Z1 CPAP offgrid (backpacking, camping) usage
Hey is correct in that the z1/z2 wall ac adapter takes in ac 100V to 240V 1A and outputs dc 15V 2A max. I also put a dc power meter between the wall adapter and the z1 and verified 15v output at 0.5A to 0.6A. I also tried to get the z1 to provide pressure treatment at 12v and 16v however was not suc...

Re: Battery solution for HDM Z1 CPAP offgrid (backpacking, camping) usage
Hi Jasper On the Omni mobile 25600 I tried both the DC output connector and the usb-c output connector to try to run the hdm z1. DC connector You are correct in that the omni mobile 25600 DC output connector supports 16V. This was the closest voltage to the hdm z1 15V requirement. I tried this howev...

Re: Trekking with Z1 APAP at high altitude 7 nights on battery $875, 5.85 pounds
I recently posted a battery solution for HDM Z1 cpap using battery power banks that output 15V via usb-c using a usb-c pd trigger cable. mech18's original post got me thinking and searching to see if recently technology improvements could reduce the number of parts needed. Battery solution for HDM Z...
