Lowenstein Prisma 20A - how can I work out energy usage for camping? - JamesD0079 - 01-06-2024
Hi all, I recently bought a Prisma 20A and it has changed my life (upgraded from resmed airsense 10). I want to take camping but have no idea of the energy consumption and thus battery requirements. I would love to be able to use my humidifier while camping as find it very difficult to use without. Can anyway advise on how much energy the machine uses both with and without humidifier? I only use a low pressure most of night around 6.5 - 8.5. thanks very much!

Don't know what energy usage is but I was chasing down the same info last week for camping as well.
Found Medistrom on google search
- Löwenstein prismaSMART series supported
- Take it travelling and use it to power your compatible PAP device when the main power isn’t available.
- Pilot 24 Lite delivers 1-2 nights of continuous run-time on an average CPAP pressure, average breathing rate, optimal mask seal and with the humidifier, heated tubing and exhalation pressure relief all disabled.
- Delivers about 19,000mAh for your handheld electronic devices.
- It can be recharged with 12 v car socket

I think the Prisma 20A has a 37v DC power supply. So the Medistrom's are probably underpowered.
The Prisma Soft / Smart machines are 24v DC. I use a Medistrom Pilot 24 Lite with this model and it works fine. Don't know if they do larger versions for the higher voltage machines.

It is power hungry. It has a big pump, heats hose to higher temps than other machines. I run mine permanently through a power station and inverter in-case of power outage (which we get a lot of). It has 720wh capacity and I have run it flat on a 10hour sleep before. Obviously there is loss due to the conversion. There is a dc power option available somewhere for the Prisma's

Thanks so much for this, I bought a device which measures the watt hours and it uses about 400wh average a night apparently, so I'm going to buy this which will hopefully give me at least 2 and a bit night's sleephttps://www.bluettipower.com.au/pages/ac180 ...
If anyone comes across a DC cable for this device and knows how you might use with a station, please let us know!!
I love my Prisma, but definitely not the best for camping, having said that I need the humidification on any device so most will be power hungry in my case. Thanks
