Using CPAP

I've been using CPAP for a long time but only RVing <3 years. Only a couple of times have I lacked power to use my CPAP. Once just the other day. Bad night!

I have a 12 volt outlet on the RVs bedroom. I think I can use with an 400 watt inverter to plug in my CPAP unit. It's an older one that used 110 volt only (110-240v, 50/60 Hz, 0.5-0.3A). It test out fine and has been my traveling unit for a long time and I don't use a humidifer.

I will get a modified or pure sine wave inverter. Since I rarely will use it on 12 v I won't have a inverter permanently mounted.

Am I being reasonable to approach using my CPAP this
way? I have 2 Centennial GC2200P batteries:

216 A/hrs
A/hrs @ 75A= 114 minutes
A/hrs @ 25A= 445 minutes
That's per each battery.

If I calculated right the unit will use 55 watts so 400watt inverter will be adequate . The label states it is 0.5 A ( per above).

If I made a mistake or something wrong put me on course! As always I appreciate all the help I can get and this forum is appreciated.
