DC to AC Pure Sine Wave Inverter SG Overview
The DC to AC Pure Sine Wave Power Inverter Second Gen is an inverter for use with the S7 and S8 Series machines and humidifier by ResMed. When using an attached humidifier, the S7 and S8 series machines require the use of pure sine wave power obtained through this inverter.
This inverter is able to convert DC power to AC power with controlled dips and peaks in power. Other inverters do not control these dips and peaks, making the machine and humidifier susceptible to power related damage. To obtain this type of the power, this inverter must be used when connected to a DC power source.
If connecting a S8 machine to a DC source without the humidifier, the DC-12 Converter For S8 Machines may be used.
Former Version: This is an updated, slimmer version with only one AC outlet. The former version was larger and had two AC outlets, however it is no longer available. To view product information and reviews for the former version, click here.

After extensive product research, I just bought this INVERTER to power my CPAP breathing machine off the 12 volt deep marine battery that I use when backcountry camping off the grid. Unlike a growing number of CPAP machines, mine cannot directly use 12 volt power; thus, I must "invert" (not "convert") the 12 volt battery power from my deep marine battery to 120 volt household level power for the CPAP, whenever 120 volt power is not otherwise readily available. THIS INVERTER SHOULD BE THE SOLUTION. By having purchased this inverter directly from CPAP, I can trust that it will work well for my CPAP machine. This Inverter produces "pure sine wave" power, which most CPAP's require for best results. It has a 90% conversion efficiency, over/under voltage protection, overload and thermal protection, and uses advanced microprocessor control. In addition to the built-in 120 volt output plug, it also has a 5 volt USB port for powering your phone as you sleep. When backcountry camping in my trailer, a tent, or out on the ground, or inside a pickup or car, I can use this inverter to power my CPAP (and laptop computer?), and to recharge my phone, as needed. To save my car battery, I will power the inverter from a separate 12 volt deep marine battery, which in turn I will recharge by running the car engine, as needed (each morning or evening, I expect). In short, I believe this Inverter is a great product and a good value. I can't wait to use it for backcountry camping. Semper Fi, USMC Veteran more...
This product works wonderful
My review centers on the excellent support provided. With hurricane Irma on the way a needed to put in place a power supply backup but my CPAP is older and parts hard to find. These folks went the extra mile and then some to help me out! Thanks thanks thanks!!!!!! more...

Portable CPAP batteries are great for two days (maybe) but then what? This little device allows me to ride 7 days on my bicycle across Iowa with 15K to 25K other riders annually (4 years in a row). Finding a charging spot (ignoring the time to charge) in a town of 2000 is a challenge with this many riders. Finding a vehicle within reach of a 50 foot extension cord is much easier. Not only does this run my machine all night every night but it allows charging of my iPhone and Apple Watch as well. This is truly an enabling tool for me. The pure clean sine wave power gives me confidence my machine will not be harmed from usage. more...

This is what it appears to be, and I have had no problems with it to date.
