Question - Duracell Powerpack Pro 1100 & CPAP Machine

Hello everyone,

I hope everyone is doing well. I have a question. It MAY have been answered, but I sometimes misunderstand things, so I want to have a clear answer for my specific situation, if anyone can help.

I have just purchased a Duracell Powerpack Pro 1100 - it is stated to run 300 watts, but has a peak of 1100. I hope I'm making sense. lol.It specifically states on the information included with it, that it powers 115v AC appliances, 12V DC appliaces, 5v USB, and jump starts vehicles, etc.

My CPAP machine is the Phillips Respironics Remstar Auto A-Flex, and does have a humidifier. I have it at 16 for pressure. (I'm in Canada). I get stuffed up, so I need this pressure to make sure I can breathe and not wake up too much.

I don't know how to figure out how long this item is going to work in the event of a power emergency. We have had some severe and long term power outages around here, lasting 10+ hours. Obviously at times if there is nothing else to do, I either want to sleep, or need to sleep depending on the time. I cannot sleep what so ever without my cpap. I cannot breathe properly when lying down when I'm awake, let alone when asleep.

I can of course fully charge the bank, then plug the machine in to it and turn it on, to see how long it would go, but, is that really the right way to do it? The CPAP machine is auto, so if I'm not there breathing in to it, would it be trying a little harder, or a little less? If the power went out, I would ONLY use the device for my CPAP, nothing else would be plugged in to it.

I hope I've included any necessary information. I have researched like I said, but I can't seem to find anything that definitively answers what I'm asking, at least not so that I understand it. lol. The electricity isn't usually gone that long, 10+ hours is in the more extreme circumstances, but I want to be sure. Being prepared is good lol. I also got a great deal on this item on amazon. $59CAD for the powerpack, brand new.

Users who own that pack report they get about 4 hours of runtime with a 40w load. I couldn't find any hard numbers on what the Auto A-Flex draws in terms of power, but with a heated humidifier it will probably be 60-100w, which would drain that battery faster.

I'd say look for something larger, this doesn't look like it would have enough capacity.

I couldn't find the specs for this particular unit, but similar power packs from DuraCell (and others) have a 15 to 20 Amp hour battery. The inverter in the pack is about 60% efficient, so it would be wise to use the 12V cable (about $25) for your pump. The use of your pump, without humidity, will be roughly 6 to 8 Amp-hours, so with the cable one long night should be doable. The humidifier, however, will add at least 4-8 Amp-hours even at low settings, and up to 30 at high settings, so this battery is really only good to run the pump without humidity.

This type of pack will probably work OK, but I generally recommend against them because they have a small battery and low quality inverter/chargers. And if one part fails, its all toast. For the same price you can get a battery twice as big and a high quality charger.

Some great information above in your posted threads CapnLoki. Thank you!

You may also want to check if your machine would run off a 12v adapter
or if it requires 24v.

I found the data on this, it has a 12 AH battery.

At 12 Amp-hours this is one of the smallest jumpstarters I've seen. Still, it should be able to run a cpap without humidity for one night.
