I don't really understand as much as I need to about this, but I think chimaera's idea of an adaptor to take Usb c (at 12 v) to a cigarette female connector (to the resmed dc to dc adaptor brick and then to the machine) seems a good idea especially for someone not well versed in electrical stuff.

Apologies I posted the low power versions. This USB C to female car 12V socket is rated for 65W which I think is well within the power consumption of the AIrMini?

Hi, Has anyone tried a USB to Car Power Socket Adapter connected into Resmed's 12-24V DC/DC converter? This should allow any power bank to be used.
