ResMed Power Station II Battery Kit for S9™ Machines

Used it two nights 8hrs each night before I got first alarm indicating 10% left.

I have used the S9 Autoset for almost four years and was delighted with the machine. It is ultra quiet, adjusts quickly and the exhalation relief was perfect. Unfortunately I had SN electrical problem with the S9 and my provider replaced ur with an Airsense 10. While it is technically a great machine it has quirks. It is slightly louder than the S9, emitting a slight hum when on but there is no wind or machine noise transferred up the hose. The exhalation relief lags behind you actual breathing and that takes some getting used to. Finally, I think the pressure algorithm is different from the S9 and that's a little more difficult to get used to. The humidification is easy and works as well if not better than the S9. Having the humidifier permanently integrated with the machine does make the 10 bulkier to travel with. The S9 had very good portability. I travel extensively and often travelled with just the S9 machine without the humidifier. In that configuration it was a very small and light package. The 10 does have better data displays but I'm a Sleepy Head user so I getting the same data that I got with the S9. I think this is a good example of how you can get a new product that isn't quite as good as the model it's replacing. If this is your first Remed machine, I think you would be very happy with it. If you were an S9 user your going to be a little disappointed.

I can only give 4 stars, since the first one I ordered did not work, but I give cpap.com 5 stars for their customer service. They shipped a new one over night while I was on vacation and I got it in 14 hours from TX to ME.

I should have purchased this a long time ago. Allows for 2 nights sleep without recharging while camping. made life much easier!

CPAP.com provides excellent service and quality products. The shipping package was secure and professional. I was truly impressed. The ResMed Power Station II Battery Kit for S9 Machines is a high quality product and easy to set up and use! First rate!!!!

The wife uses this with her Resmed S-9 when we go camping and have to use battery power. The unit lasts all night with out the humidifier.

Battery works OK, but for a $700 price tag it does NOT included discharge protection - it WILL become a brick if you do not charge it regularly if not in use. This is a simple, solved engineering issue, and it is unforgivable that ResMed does not include this in this expensive unit. Go for the CPAP lead-acid battery instead - this ResMed clunker is a money sink just waiting to bite you in the wallet.

Product arrived on time as expected. No complaints the battery works great. I have the ResMed S9 machine and it will run it through the night without issue. I just wish I could run the humidifer. Maybe if I bought the additional battery and combined I may be able to run both.

I used the Resmed Power Station II Battery with my Resmed S9 Elite CPAP (15 cm H2O) during a recent international travel (PR to New York and New York to Germany). Delta allowed me to turn ON my cpap unit inflight after calling them a week before departure for notification. Had a pleasant 7 hours sleep without consuming the battery power. The unit is extremely easy to operate and charges back quickly. To recharge, you need to use the S9 power supply - not included with the battery pack. Charged the battery in Germany with a power converter without issues. Battery comes with a quality travel bag. Based on this experience, I highly recommend this product.

I bought this battery to use when I went on a Safari trip to the Serengeti in Africa. It easily lasted one night with power to spare. My setting runs at 12.5. I was able to recharge the battery off the solar power units at the camp during the day when no one else was charging camera batteries, so I had a full charge every night. The only complaint I have is that you have to use a small adapter to hook the power cord to the battery for recharging. Keeping up with that little adapter was a bit of a pain. It would be much better if all the connectors were the same style. The battery is a little costly, but I was willing to pay the price to be able to travel comfortably. I definitely recommend this if you need to sleep, but don't have access to a power source.

This battery will last a couple of days which is perfect for me if there is a power outage or am camping or on a long flight. It is hefty, but lighter than some others I have used. Make sure you have the right machine or connections to go with this battery before you order.

This product is great, it can power my cpap for at least two 8hr nights of sleep before needing to be recharged. I only wish that for the price a power brick was included so I wouldn't have use the power supply from my cpap.
