I purchased the battery pack last year, for about $350 and get about three 8 hour nights with a full overnight charge, at home, beforehand.
My issue is that i want longer camping trips and do not have access to plug in power to recharge. I took my battery pack down to our local battery store and found that I can use a power inverter in my truck to plug the battery in to. What I also found out was that the battery in the special remed bag is only worth $37. A few more $ for the cords and inverter/converter (i'm not sure what it is) and that means I paid at least $250 for the nice bag the battery is in. I will use a power inverter in the future but i also bought another battery as back up and it was a bit smaller so it also conveniently fit into one of the pockets of my very expensive remed bag.

Will the one they make now not work? I would think it would, but the battery time would be decreased just as if you used the humidifier along with your cpap while on battery.

No it will not, not sure why but the PR 60s are listed as non-compatible. But Respironics have a dedicated 12VD DC cable for $25 which i can plug into my powerstation PSX-2, which i got at costco for $60

probably not going to run the humidifier but should do the odd night and much cheaper than the battery packs.

I just got my Powerstation PSX-2 and used it with my Respironics System 1 with humidifier on a camp out. I got a solid two 6-hour nights out of it, and I suspect I could have gotten a third night as well. For conversion, I just bought an adaptor for cigarette lighter input. I got one with a 75 watt rating, as my System One has a max wattage draw of 60 watts. Can't beat the $60 price at Costco!
