I have a 120vac CPAP machine which is 15 years old. It draws 2A for the blower and 2A for the water heater.

I do not have an inverter in my new Lance 1040.

What make and model of CPAP machine operating on 12vdc with a standard plug have you used successfully? I know I will probably have to forgo the water heater.

I would look here.

I have been using a Repironics Bi-Pap Machine for as long as I have been on Cpap Therapy. Over 10yrs. now.
The company in that link sells everything you will ever need.

When I was diagnosed with severe sleep apnea 15 months ago, I told my HMO that I had to have a machine which could run on 12V DC. They provided one. I bought the matching DC cord from CPAP.com. This setup works fine in the camper. Just be sure that you get a cord which matches the make and model of your machine.

Before the cord arrived, I ran my CPAP setup with a small inverter. That also worked well. I have a Duracell Pocket Inverter, 100W size; other manufacturers probably make something similar. This inverter plugs into a 12V socket.

I nearly always dry camp, without generator or solar, so I monitor the condition of the battery bank. It recharges quickly when I drive the truck. If I plan to stay somewhere for a few days, I turn the heated humidifier part of the CPAP off or down to conserve power. If I will move camp soon, I run the whole thing. No problems so far.

If you also have a heated hose, watch the power consumption for that.

There are several online retailers that sell dozens of brands and models. Many of them offer either a self contained battery or dual voltage capabilities. Google search CPAP machines and youll be surprised at the variety.
