Sleep apnoeia

I try to spend a week away camping each year, but have to have a vehicle close by and take several caravan batteries in order to have the CPAP machine working for the full time. Nothing lightweight has the capacity to power the converter for the necessary time.
 
@Resurgam - my machine lasts 3 nights on a charge and I check that I can recharge the battery at the campsite if I'm staying longer. I do a lot of camping/boating and would love to have a bit more flexibility/ less kit to pack! In the meantime, I'll keep scouring the ads for the elusive high power/long lasting/low volume/low weight power pack!
 
Have you investigated solar power possibilities?
 
Interesting - I'll have a go at that.
Thanks
I know there are solar chargers people attach to their rucsacs while walking during the day so as to have power at night, but I've no idea if they would be powerful enough for you. And of course walking in summer abroad might work better than here!
