Trying to use small inverter through cig. lighter adapter

I am trying to run my CPAP machine from a light fixture above the bed instead of through the main inverter. I wired a 12 v cigarette lighter outlet into the fixture. The voltage reads 12.5 v and I can run other AC appliances through the portable inverter at the new connection. This inverter, which says 175 w peak and 100 w continuous also works when I plug it into the cig lighter on the dash with the CPAP but not at the new connection. The CPAP adapter says it requires 90 w.

Why will my CPAP machine not run at the new connection?

Are you also using a humidifier? If so, that may be the issue.

Too much too small wire feeding the outlet.. The voltage is dropping under load.

you need to find a stronger wire in the bedroom.....

QUESTION, is there a slide out for the bed? and if so what is the make of the slide system,, Accu-Slice there will be a controller, likely either above the slide or below it a piece of fascia covers the area.. Tap the power to that, that lead can hauld hte freight just fine.
