Check the voltages. USB might be 5V DC out. Is that enough to power your CPAP?
Oh really? I always assumed it was 12V. Never mind then...
Use your favorite mask. Eveything else is included. Power cord from battery is a direct fit into cpap. Battery set at 12v. All fits in spiderman lunch bag, padded for protection. This 32000 ma battery is about $90. Sorry the sae connector is not shown. it is on bike waiting for trip. dc charger is the excact size of AC.
That was a test run for a last minute camp trip. Lasted 2 nights (18 hours at 11.5 average pressure). As you can see above. I have got a smaller bike set up. It lasts 3.
Also, if you hold down the power button on the z2 for about 7 secs, it will let you set upper and lower pressure. I had to turn up min pressure to 6.5 with ramp off and pressurre relief at 1. Machine max is 20.
My setup exactly. Works very well and I'm getting better than three nights to a charge.
I discovered something last week at 8000' altitude; my Poweradd only lasted one night at that elevation when it normally lasts two. I remembered that they have issues at altitude but don't know why.
I live at 8300'. I have not had that experience. I would guess it might be your unit more then the battery??????? It will have to work harder to create pressure at altitude????
has anybody had success charging the Poweradd off their bike's 12v hela din/powerlet/cigarette socket? The combination of the Poweradd and Z2 looks hard to beat.
Well, I'll tell ya what. We will use them and report back on our results.
So far so good but it is early yet.
I reread what I wrote and it came across the wrong way. I meant to say that CPAP's in general have warnings about using them at high altitude as they have to work harder since one is breathing harder to make up for the lack of oxygen. Thus my battery pack only lasted one night at that altitude where it normally gives me two nights at much lower altitudes. Perhaps it would be good to have another qualifier of altitude along with pressure settings...
I get 3 nights from poweradd at 8320' @ 8.5 pressure
I read reports of the batteries being defective out of the shoot as well. Alot of those were older. If the battery lasts more then a year for the 85 bucks i paid i will be satisfied. I will recheck but i think the warranty is 2yrs.
There is a lady on the apnea board who is an avid back packer. She has 2 when she packs for a week. 3 years now, same 2 batteries. Another river rat with same experience.
Sorry, I missed the post where you were elected representative for all of us here.
My first Poweradd charger was DOA. Sent back and the second one worked great,,,until it didn't any more 7 months later. Wouldn't hold a charge and got very warm when plugged in. I've since moved on to a different manufacturer. YMMV.
You misunderstood - I was using the royal We - hope that clears things up.
OTH, you have contributed a useful anecdote regarding what may be a problem with the life expectancy of these batteries but failed to mention what other manufacturer you think might be better. Let us know how that battery works out.
One thing that hasn't been addressed is the finite number of cycles that all batteries are subject to. Nothing lasts forever. I was just happy to find a solution to power my CPAP while away from the AC outlet. I did test a couple of options before I found the Poweradd. If there is something better I'm sure other CPAP users would like to know.
Indeed, The Dude abides.
How long ago was this?
What battery are you using now?
Honestly, as easy as it hooks up to everything, for the money, if it makes it through my trip this month it will worth the money.
Here's a crazy thing, we both have CPAP's both use the same model (phillips dreamsonic)
We both have the phillips branded 12vdc power cords.
Now, in our truck camper we have a duplex 12vdc outlet, her machine plugs directly into the outlet, mine is on an extension cord.
I'm getting a low voltage message when mine is plugged into the 12vdc extension cord, but it's fine when plugged into the duplex outlet.
Does anybody know what the min voltage/milliamps are needed to run these?
My power is fine I have a decent (+210 amp-hour) battery set up with solar
