Review on ⚡ SunMilY 150W Portable Power Supply Inverter: Milwaukee M18 18V Battery Compatible | DC 18V to AC 110V~120V | Modified Sine Wave | AC Outlet & Dual USB | Battery Not Included by Ronald Lunn

I wanted to try this with my cpap to see if it works. I charged it last night with two 8Ah M18 batteries. I set my cpap to turn off the air conditioning and humidity and put it on airplane mode for the least consumption. I slept for 6 hours and when I woke up one battery was flashing and the other was fully charged so I'm guessing a constant draw. I only heard the fan once in blockspin. I will leave the batteries as they are and check again tonight if it lasts 2 nights with 2 fully charged batteries. I will amend this review if I have any oddities.
