G'day from Australia.
Wife has had a CPAP machine for years - just ran on mains power - 240 v AC in Aust.
Just got a more modern machine which has an inverter for the 24 V [DC presumably] the pump runs on.
Question  - does an inverter use any power from the grid when the CPAP pump is turned off?
Or should I be 'energy concious' and turn it off at the wall switch?
Thanks in advance for the usual good advice.on NAT.
