Help for a newbie wanting to travel/camp with CPAP

Hi...hoping someone out their in "apnea" land can help with this...

I am hoping to be able to take my unit (S9 Auto set) camping (at a non-powered site) & also have a back up plan if there is a power
outage at home. I did a bit of a search on google and apart from marine batteries which would be pretty heavy to cart around, I
came across the following options. Has anyone had experience using these or can you offer any other suggestions?

CPAP Battery, Inc. http://www.cpaptravelbatterypack.com/
Super CPAP Power Packs http://www.cpapbatterystore.com/testimonials.html
Respironics Battery Pack https://www.cpap.com/cpap-battery-power ... attery.php

I live in Australia and can purchase a DC converter here but we do not seem to have as many options available as far as portable batteries go as in the U.S.
Any feedback/advice would be much appreciated.

Thanks
Caro

Morning Caro
I am a camper too as a matter of fact I'm headed out on Monday for the week with a group of friends. I use a 12 volt deep cycle marine battery and a modified sine wave converter......and yes it weights a lot. You can hook up the same way to your car battery if need be or you can go with smaller lithium batteries...just like a lap top battery. I bought a little trolly cart to lug my battery around from the house to the motorhome and that works great. Now I can wheel it around instead of grunt and groan when lifting it...I'm an old lady so lifting isn't so much fun
Happy sleeping and happy camping.

Thanks nanwilson....appreciate your comments & suggestions. Enjoy your week out camping & breathe easy!
