Any one use either of these 50000mAh batteries?

I have the used the Poweradd Pilot Pro 32000Ah Battery Power Bank with my Phillips System One APAP quite successfully. I want to add another battery to my camping gear and I noticed these on Amazon as I was about to order another Poweradd.

One is a MAXOAK 50000mAh 6 Port(5/12/20v) Portable Charger External Battery Power Bank (https://www.amazon.com/MAXOAK-50000mAh- ... Power+Bank)

and the other a Crave PowerPack 50000mAh Dual USB + Dual Laptop Ports Ultra-High Density Power Bank. (https://www.amazon.com/Portable-Charger ... 3M61ZGD1JA)

Wow, even more power for dry camping if it works OK. I have a fold out light weight solar panel so with 2 batteries I can charge one while using the other. BUT, I don't know anything about either of these batteries. Anyone with any experience with either of these or more knowledge so to understand if they will work from reading the descriptions?

If you can - thanks for helping out.

Is this the one your currently using? https://www.amazon.com/Poweradd-Pilot-P ... B00DN0KBXU
I would like to get a battery back-up for my Apap but didn't think these would work for that purpose.
How long can you power your PR system one with it?
I assume your not using the heated Humidifier with it when on battery power?
If this will actually work I would get one to cover me when we have a power outage.
Most sold for Cpap use are in the $250+ price range from what I have seen.

The one you have now can output up to 4.5 amperes at 12v DC.
The two others max out at 2.5A.
So, I'm not sure that one of these would be capable of supplying enough current for a CPAP by themselves.
(For example, a DeVilbiss IntelliPAP requires up to 5A at 12V I believe a PRS1 is about the same.)
By means of comparison, the Freedom battery sold on cpap.com has a max current of 8A out.
For camping, another Poweradd seems like a winner since it's on sale right now and you know it has enough "oomph."

As an aside, for airline travel there are actually capacity limits in the rules for carry-on Lithium Ion batteries.
Anything over 100 watt-hours technically requires airline approval. The Freedom battery is just under the limit.
The Poweradd is 118Wh and the MAXOak is 185Wh.

Thanks VinnieBarbarino - just the info I needed. I'll get another Poweradd 32000 like I have!

Yes that is the one I use. With my Phillips System One 60 set on a pressure of 10.5 - need to start at pressure of 8 and ramp of 5 min or the sudden demand trips the battery, - I can get about 3 8-9 hr nights. But I usually recharge, either by fold out solar panels or generator, after 2 nights, when dry camping, if I can.

Thanks Jagzoo for asking this question. I had been looking at those batteries also but noticed the 2.5A output so didn't think that was going to work. My PowerAdd Pilot Pro has been working for me for almost 2 years now so I think I will stick with it.

Jtravel, I use my battery for one night usually then recharge from my truck battery the next day while we are driving. The battery will give me 2 nights but I usually recharge daily. There was an earlier thread on this and some people didn't get this battery to work with their Cpap. But if you want to try Amazon has a good return policy. I guess Jagzoo and I were lucky ones. I run my PR 760 at set 11 Epap and 15 Ipap. I start right up at those pressures without a problem.

Have you considered a deep-cycle marine battery? If size and weight are not a consideration, it's cheaper and maybe safer for your application:

Most of the Li Ion batteries on Amazon are really intended for recharging phones or extending the life of a laptop battery.
Asking a small device to pump out (potentially) 60W is a bit much if it was not engineered for that purpose (Again, my humble opinion )
Being purpose-built (small, light, high-current, airline-friendly) may justify the higher price of the CPAP batteries.

*NOT* marine, just deep cycle.

I use these batteries in situations where a large heavy battery isn't feasabile for me I.e. camping with backpacking, overnight hiking etc. even for backup at home where one just stays in my bedside drawer! I do love my Poweradd - I can also easily use it to power other digital devices.

I'm with you - in JTravel's case maybe a heavy battery wouldn't be a problem. I think you did very well to find the Poweradd and give it a good workout.
That expands the options for everyone else who is looking for portable power. It's tips like yours that bring me here.

I agree with what you're saying about Lithium Ion packs which are not designed for cpap use. The Powerad seems to usually perform well but others have come up short, often because they shut down on a modest load.

However, the link that you post is rather dated and gives advice that by today's standards are rather suspect. For example, although traditionally deep cycle batteries were easily available in the marine market, that is now not the best way to get one - they will be either overpriced (i.e. from West Marine) or cheaply made (i.e. Walmart). The important thing is "Deep Cycle." It mentions up front testing the electrolyte, which is the proper way to measure charge on a traditional flooded battery, but completely unsuited to the cpap market, where the battery is located either next to the bed or being carried around. It also mentions prices that are about half of the current prices, and equipment that is not available. The "examples ofr solutions" listed are only marginally relevant to today's world.

Rather then a "marine" battery, users looking for a "lead based" solution (i.e. not our OP) should consider an AGM battery, as currently used in mobility scooters and UPS's. I like the U1 size, 24 lbs, 35 amp-hours, but they come in a variety of sizes from 7 AH to 100 AH. Being lead-based, they will be heavier than lithium, but otherwise they are full sealed deep cycle batteries that are commonly available at a reasonable price.

Yes! A much better option, thank you!

Thanks for the details, I will have to look into this.

I just finished living off grid for 3 months on solar. I found that I averaged 10AH a night without humidity. Be aware that many battery packs greatly exaggerate their AH capacity.

amp hour ratings are meaningless without an accompanying voltage spec.

10AH at 12v is hugely different than 10AH at 3.7v (which is what many lithium packs are spec'd at)
