i'm bringing this solar powered/charged inverter to run the cpap machine.
the panel charges during the day and the inverter runs absolutely
silent all night. i ran my cpap machine for four days on one charge.
this particular model produces up to 500 watts and has a 1.2 kWh lithium battery.
the solar panel produces up to 220 watts for charging or use. the panel foldes up
into a small brief case size carrier.
cool!
