Resmed S8 DC-AC PSW Power Inverter Overview

An inverter converts DC battery power to AC wall power. ResMed humidifiers can become damaged if the battery power is not inverted into a clean AC power source. Most inverters do not generate a pure signal from a DC battery and the Humidaire heated humidifiers are susceptible to power spikes. The 'Pure Sine' refers to a signal wave with controlled peaks and dips. Power signals that rise or fall erratically are dangerous to electronics.
You will not need this equipment if you are just powering the ResMed S8 machine. Use the 400 Watt DC to AC Power Inverter or similarly basic inverter with a minimum of 150 Watts continuous when not connecting the Humidiaire heated humidifier.
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 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 is not recommended for most machines. Equipment like the Respironics M series and ZZz-PAP machines will use the simpler 400 Watt DC to AC Power Inverter .
We include information about the power needs and capacities on the CPAP.com pages our products. Please see the "POWER" tab on any machine product page for this information. You can also see a summary of the voltage range and whether it is DC capable on our Compare Charts.
Here is a video explaining differences in power cords and power supplies of various CPAP machines:
All CPAPs will operate on DC power with the use of an Inverter to change the current from DC to AC before it reaches the machine. However, many will operate on DC power without the need for an inverter, just a power cord that plugs into the CPAP and ends in a cigarette lighter plug.
Inverters do require a lot of power. If you need to use an inverter to run your machine on battery power, the inverter will probably take about half the life off the battery.
To determine if your CPAP will operate without an inverter, look for a DC outlet on the machine, either at the back or on the side, with a single opening directly in the center. It should be labeled "DC POWER" or similar term. You can also review our Compare Charts to see if your machine has a optional DC cable option.
Here is a video describing different DC cable and battery options for various machines:
All the models CPAP.com sell contain power converters that enable the machine to operate on any AC current from 100 to 240 volts without any adjustment.
All machines can connect to DC power. Some machines are configured to operate on DC Power and have a DC power outlet. Other machines require AC power and will need an Inverter that turns DC power to AC power.
Having the proper equipment is the biggest key to successfully operating the machine from a battery. For example, if your machine does have a DC outlet and you want to run your machine from a marine battery, be sure to get the correct DC cable for the machine, as well as an adapter cable with alligator clips that fits over the cigarette lighter plug.
CPAP.com sells complete battery kits with everything you need for many machines including the correct cables for those machines and batteries. If you have questions about the specific power needs of your machine, review the 'Power' tab found on the machine's product page, or give us a call at 1-800-356-5221.
There are small, portable battery packs that will operate a CPAP set at 10cm for at least one night, or about eight hours. CPAP.com sells full Battery Kits that come with everything needed to run your machine off battery power including the correct cables needed for your machine and a battery. You can find the battery kit for your machine Here. On each battery kit page, you can input your machine and pressure setting to see an estimate battery life for your machine.
Some machines have batteries created to be used specifically with them only. Here are some of the machines we carry with integrated or specialized battery options:
Transcend EZEX miniCPAP™ Machine
Z1 Travel CPAP Machine
Transcend Auto miniCPAP™ Machine with EZEX
Z1 Auto Travel CPAP Machine
CPAP.com sells Battery Packs to accompany your machine if an integrated battery is not available. Visit CPAPtalk for more advice specific to your needs, or view this past thread on the topic here.
I don't have an oscilloscope, so I didn't test its claim to produce a "pure sine wave" but this product powered my CPAP device and heated humidifier for two nights while camping.
I cannot wait to go to the back country now that I have a way to power my newly purchased battery pack. Traveling will be so much nicer now that I have this option.
The machine works great however the 12V ability via the RV we have didn't produce enough juice.
Worked excellent on a five day camping trip in a pop up camper using a 12 volt deep cycle battery. Did not use the humidifier this time.
The inverter was what I was looking. Thanks
I run my Inverter while camping from a 12V/20 amp deep-cycle electric scooter battery that weighs about 13 pounds. I get just about two nights of CPAP use from this setup before I have to recharge the battery with a Battery Minder / conditioner. Everything fits into my CPAP travel case (without the humidifier - which is a power hog anyway.)
Auto plug-in cord should be longer
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!
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.
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.
very happy with inverter. the only fault i see is the plastic nuts crack easily and when using humidifier the inverter fan seems to make the noise ramping up and down with my c-pap machine overall Im happy with the inverter
bought to run my S8 Auto Set II this summer. should do fine.
