Good for using CPAP while camping

I purchased this because the Resmed 12Volt cpap adapter that i had previously purchased was big, bulky and heavy and I wanted something smaller for our compact RV. I had a moment when I first plugged in my Air Sense 10 because the light on top came on when i plugged it in then went off, then flickered. It took me a minute to realize there was nothing wrong with the adapter, the air sense unit alway does this even with 120volts. Plug it in, the light goes on, then off then flickers, then comes on and stays on until you use it. I wonder if the adapter would maintain voltage as the resmed unit does when voltage declines, but with lithium RV batteries, I don't think it's as much of a problem as it might be with lead acid batteries. We've used this over 23 nights without any issues. Good product.

We went to girl's camp for a week in tents. This worked fine to convert our 12v battery bank to power the Airmed without going up to 110v and back down to it's voltage. This saves a good bit of battery power. It was very humid at night so we were also able to turn off the water and heater with no dryness in the morning. All-in-all it worked well.

Works for my CPAP when I go camping. I plug this into my portable power supply and can go DC to DC allowing me three nights on one charge.

I've had a deep-cycle battery and some solar panels for a while. I use them while camping out at the farm where we don't have any power, to recharge battery-powered power tools (chain saw, brush cutter, lawn mower, etc). I had been using a 300W inverter to power my CPAP (never go a night without it!) and while that worked this seemed like a better solution. I use this and a DC Socket (NOCO GC018 15A 14AWG 12V Adapter, Heavy-Duty Cigarette Lighter Plug, and Female Socket with Eyelet Terminals - https://www.amazon.ca/dp/B00G8WLW2Y) connected to the battery. It worked wonderfully on Canada Day long weekend.

Makes it possible to be used with 12 volt battery it case the power goes out.
