Using a UPS

[gumbloid]

Good day fellow CPAP users,

I had a quick question: have any of you had any success using a UPS (Uninterruptible power supply) in conjunction with your CPAP machine. Over the last couple of years, I have noticed (especially in the summer) sporadic power outages; some are minutes, others are hours. For those using a UPS is there a particular brand and model number? Any input would be greatly appreciated.

Yes they work. But not for long, especially with the humidifier on. There are threads that go into this in great detail if you search...

The UPS will save you from outages though.

If you plug it into the right slots, UPS make good surge protectors also. Had a UPS stop a surge from a near by lightning strike at work. The high dollar surge unit plugged into the other outlet fried itself and took the electronics that were plugged into it with it. Nothing happened to the units plugged into the UPS.

How about the ResMed dedicated BBU? Anyone use it? Claims to be able to run for 13 hours with the humidifier, but compared to a large UPS it is tiny. Something in the laws of Physics don't make sense here....

Most consumer grade UPS's these days are "standby" mode units and just connect the input to the output when the power is on. The UPS part of the unit provides no protection. Most consumer grade UPS's have a surge protector built into the box, but I suspect it's no better than separate surge protectors.

An online/double conversion UPS does give you a certain degree of extra protection, but they're more expensive.

As I understand it, a UPS would get you through short outages, but wouldn't power a CPAP through the night. There are rechargeable battery setups people have done with marine batteries, and there are also rechargeable battery products sold specifically for CPAP -- some of which can be used to automatically kick in when an outage is imminent.

Different CPAP machines have different power requirements -- so make sure whatever you do is appropriate for your equipment.

I have a number of UPS systems at home for a lot of electronic equipment.

Never thought of getting one for my new CPAP (just 5 days old).

APC has one model, their Power Saving Back-UPS Pro 1500 with an output of 865watts/1500va. Their Battery Run Times are 2hrs at 50w and 1 hr at 100 watts. My Resmed Airsense 10 Elite uses 53w at typical power consumption with up to 104W at peak power use.

The APC 1500 can use an external battery pack that will triple those runtimes.

Even without the extra battery pack, I would have enough run time to recognize the power outage and get on backup generators.

OH.. The BR1500G has AVR so it regulates your AC to the device to prevent spikes or brownouts from hurting equipment attached thereto.

PS. Just ordered that BR1500G from WallMart (store pickup)

Glad I searched "UPS AVR" here before I bought a UPS for my CPAP machine and read about your opinions on it. I got a current model Prolink 650VA/325W UPS solely serving my Resmed Airsense 10. I want to manually shutdown my CPAP machine during a power outage and I just need a few minutes of back up power.

I don't know about the power situation in your countries. But here in the Philippines most voltage disturbances occur during the monsoon and typhoon season in the second half of the year. I thought the price of a UPS protection (with surge and AVR features) is peanuts compared to the price of a Resmed Airsense 10.

I have read a number of threads about this topic here and elsewhere on the www, and generally people become convinced, after reading, figuring, or trying for themselves, that the UPS solution is going to end up costing about as much as a dedicated CPAP style standby battery, the Li ion variety.  This is because if one wants the garden variety UPS costing about EU100-ish, or about USD$130-ish, plus the cords/adapters, you'll need backups to THEM...or added potential by daisy chaining at least two of them to get the heavier users through the night.  One night.

This is not to say almost no UPS will suffice...some of the more costly ones will, but can you put them in your carry-on?
