Why run an inverter to change 12VDC to 120VAC when you are going to use the AC to run a power supply to convert it back to 12VDC? Seems inefficient.

Apparently using the stationary concentrator like that won't work. But using the portable would. At 12 volts the portable uses 6.5 amps. The inverter was not for the portable concentrator, that is for the CPAP.
