Key Product Information

    Manufacturer: Aims Corporation

    This is a pure sine wave DC to AC power inverter. Use this device to provide clean AC power to any CPAP. ResMed S8 machines are required to use a pure sine wave AC power source; particularly, the ResMed S8 Compact is not DC compatible and must plug into a wall socket. You will need this product to operate the S8 Compact or any other S8 machine using the standard AC plug.


    Returns Offered on Warranty Issues Only

CPAP.com Comments
The use of any inverter will reduce the battery life up to 50% because the inverter, itself, uses battery power.

You will not need this equipment For ResMed S8 models Escape, Elite, Vantage, or VPAP. These units are DC compatible and only require the DC-12 Converter For S8 Machines allowing you to use any battery without the Pure Sine Wave Inverter.

The Pure Sine Wave Inverter will not work with the CPAP.com Battery Pack. Please visit our Power and Batteries section to select an alternative DC battery source. If you want to use a CPAP.com Battery and need a means of charging the battery while camping outdoors, use the 400 Watt DC to AC Power Inverter.

The Pure Sine Wave Inverter will not work with ResMed S7 machines or Respironics M series machine.

Better than the previous version!   September 30, 2009

(5 out of 5) by Patrick

"I had been using the old AIMS 300 pure sine wave inverter. I paid about $180 for it 2 years ago. The previous model doesn't have a fan and it made some really loud noises when powering up a device. I came across this new AIMS 300 and was pleased to find that it does have a cooling fan. It still makes the clicking noise when it's supplying power to certain devices, but it's not as noticeable as the older model. And oh yeah, the model is cheaper too!"

AIMS Pure Sine Invertor   April 03, 2009

(5 out of 5) by Raymond G, Rockford, IL

"I had purchased other cheap 'modified sine' invertors in the past which made my sensitive electronics buzz and my laptop computer reboot and sometimes behave erratically. Each year, we drive from Illinois to Florida, with a stop in Georgia. We needed a way to keep our children occupied for the 22 hours and have found DVD's, video games, and a laptop computer provide variety. We are very plased with this invertor as our sensitive electonics work correctly and the buzz/hum is gone from our portable DVD player. I tested it with various electronics and even plugged in a meter which showed it was operating as clean or cleaner than home power. I will definitely buy another one again."

AIMS inverter   March 24, 2009

(5 out of 5) by Jay L, Pineville, LA

"I bought this inverter to use camping to run my Resmed Escape machine and humidifer. I've used it 3 nights so far and it has done just fine. I'm using a 75 A.H. deep cycle battery which also has a 750 watt modified sine wave inverter hooked up to it. Ran the pump 2 nights, made coffee in my 4 cup coffee pot and still had lots of power to go. I suspect it would give me at least 4 nights plus coffee every morning. I'm happy with it. I read where others cracked the little plastic nuts. Just don't crank down so hard.
I'm completely satisifed so far."
