new battery technology for CPAP during blackout?

[CarlSam108]

Omnicharge is a company that just released a battery that has its own inverter, so you can plug a device into it and the device thinks it is plugged into 120 volt A/C wall power.
They claim the battery has the intelligence to adjust the power output to the needs of the device.

Some on this forum know may more about battery power characteristics than I do -- any idea whether an Omnicharge battery would work on a ResMed AirSense 10 Autoset? and how long it would last.

ResMed sells its own battery but it costs over $700 and from what I've read, only works for one night at most with heated hose and humidifier. The 20,400 mAh Omnicharge battery is $300 and has many other uses (like powering laptops) so even if it only lasted for half the time of the ResMed battery, it would still be a better value due to its other uses ... that is assuming it works at all.

I found the spec sheet for the ResMed battery but it does not disclose the mAh of battery storage, so it is not easy to compare the products

Alternating current is distinguished by its ability to adjust supply to meet demand.
Nothing new here.

My old AEIOmed Everest 3 CPAP had an integrated battery pack. It was no larger than my current DreamStation with the battery and the humidifier. It even had a pre-heat feature like the DreamStation. Unfortunately, that company went out of business after its factory in China burned down in 2011.

This unit was only available with a constant pressure, kept no data except for an "odometer," and did not support a heated hose. However, the modular design would have allowed for all these features to be added if the company had stayed in business. Maybe one of the current manufacturers can buy the patent and incorporate this design.

A 20,400 mAh Omnicharge battery is $300

If you are the least bit handy you can put together something for < half of that or less depending on what you wanted 100Ah or 35Ah Deep Cycle plus the cords which you would still need for your make/model cpap. The 100A could last for many days the down side is size and weight but then you could use 1 or more 35A batts.

fwiw - back in the day I worked on a IC chip making device called "Omni Etch".

Using a inverter is normally not a very efficient use of battery power.
You would be better off running the Cpap on DC voltage.

Assuming that follows the standard for lithium batteries, that is only 7AH, a small lead acid SLA. You can get a 50,000 li pack for around $100. Those will get you by without humidity.

I wondered the very same thing.

could be, but if so, he's not doing much better than the shills for so-crap do

That battery pack he's linking to isn't just a DC output (or even an AC inverter). Newer laptops (and my Respironics CPAP) have a third wire on the DC connector, which the device sends a pulse down to identify what it's correct voltage is, and the power supply then adjusts the voltage to suit the device. It's quite sophisticated technology compared to two crocodile clips on a car battery, but is pretty standard on powerbanks that are designed to charge laptop batteries (which is what that battery pack he linked to is).

What I don't know is whether the specific battery pack (or powerbank) has the correct programming to identify the CPAP machine. I'm personally looking at buying a laptop powerback to use as a travel backup for my CPAP (I've been stuck in hotels and B&Bs when they've had power failures before, and it gets pretty boring sitting there in the dark waiting for the power to come back on so I can go back to be). I've got a huge battery at home and an old Resmed that runs on straight 12V for when there's an outage at home. The plan is to find a brick and mortar shop, so that I can test whether the CPAP works on the device before buying it. They're not cheap so I don't want to take the risk that I get it and it works for my laptop (which is a luxury I don't really need) but gives an error on the CPAP. Romoss make some nice ones and I'm waiting for their new SoFun 9 Premium to come out later this month. http://www.romoss.com.sg/product/sofun-9-premium/

Better buy three, one for your laptop, one to power where you are staying's at internet, and one to power their WiFi. Jim

Where did you find that information?
I'm Curious as Some have looked at the Resmed 10 and PR dreamstation power adapters and found only a resistor between the + power side and the new third connector. This allows the machine to verify It has the correct manufactures power adapter connected and will not turn the blower on if it is not.
You will need to buy the DC power adapter Cables sold by both manufactures if you want to use a DC power supply.
If using the AC Inverter option you would need to use the included ac power brick that came with your Cpap.
