We we're thinking about going off grid and I have a cpap machine. I would like to get 12v power by the bed to run a small inverter or get a 12volt power supply for it. Any options of where to get power from?

I don't know how many amps or watts you need to power the machine. I added a 12V outlet over the nightstand by running wires to a reading light over the bed. All wiring is hidden within the cabinetry.

I don't know how particular a cpap machine is when it comes to its electrical supply, but be aware that some of the cheaper inverters don't produce true sine wave power and that may (or may not) cause an issue with your machine. Depending on how much power the cpap needs, it may be easier to connect the inverter close to the battery and run 110V wiring to a dedicated outlet near your bedside.

I have the C281BH, and have Cpap. while your question doesnt pertain to the trailer so much  CPaps can take a ton of power to not a lot depending on how you run it. I own a Batteries Plus Bulbs and get asked this type of question a lot. I hooked my machine up to a Kill-a-watt device to tell me exactly how much power I use. with the CPAP plugged in but not running it used .17AH With the unit On and the humidifier disconnected it used 1.67 AH with the unit on and the humidifier running 2of5 it used 6.1 AH I have another unit that has heated tubing, it used upwards of 9.4ah with everything on. . So my trailer which is a 2018 C281BH came equiped with a very small group 24 deep cycle battery. rated at 80ah you actually see about 60% of that in usable capacity if you do whats best for the battery as far as draining it down. which is 48ah on this battery. Think of the AH rating on the battery as how many gallons of gas you have in your tank. The Draw from devices hooked up to your battery as using that many gallons in a hour. so in my case I could go about 3 nights of dry camping on my one small battery if I unplug while not in use and only run it with the humidifier. (40a worth of draw sleeping 8hrs a night) I could go one night if I run my humidifier (48a draw sleeping 8 hours) my numbers I left do not account for inverter loss or any other appliances running. so if you do not have a way to charge like a generator make sure you know how much battery storage you need before you go. |
