Pilot-12 Lite CPAP Battery for Respironics DreamStation and System One

Originally disappointed because the battery came having already been opened and I was unsure of what it had been through. Happy to say this battery is incredible, I use a Philips Dreamstation and I can report the following. After receiving it I brought it to a full charge and in both situations I ONLY used the battery and did not bridge wall power to battery then to CPAP#1. First test I used battery and my CPAP was set to air pressure = 5 and Humidifier = 1. I got 4 hours use out of the battery and had to wake up and connect the CPAP back to wall power.#2. Second test use after fully charging it again I set my CPAP to air pressure = 5 and set Humidifier to "0" - on this setting I got just over 3 nights (26 hours) CPAP use from it - incredible and far exceeded my expectations.The unit did come with a cord to get from the battery to your CPAP and I use the CPAP power cord to charge the battery. Also this battery DOES allow you to use the battery as a bridge in case of power outage i.e. CPAP power cord to Battery and Battery cored to CPAP - then if your power supply from the wall gets interrupted your battery automatically kicks in. I bought for an international trip to a country that has frequent power outages, but this will also be my new camping supply instead of a generator. There's also a USB on the front that allows you to charge other items as needed.

I've read lots of reviews but not a lot of them provide details about power usage but I have in this review. My configuration is a Dream Station 2 with the Pilot12 Lite power supply. When testing I used a fully charged Pilot12 Lite that was not plugged into wall outlet, meaning it was not configured as a UPS. This entire multi day test was on that single charge of the Pilot12. I turned off the humidifier and heated tube for this test as I wanted to see the best case performance of the Pilot12. I also only plugged the CPAP into the Pilot12 right before use and unplugged it when I woke up so it wouldn't drain the power unnecessarily. The first night my CPAP ran from 10:00 pm to 7:00 am with no problems. The second night it ran from 11:00 to 6:30 with no problems. The third night it ran from 10:00 to 4:50 at which time it ran out of power. So I essentially got about 2 and 3/4 nights worth of power out of the battery on a single charge. This was indoors in a house that's probably 50 degrees at night, no ac just open windows. I like it cold when I sleep. I am very pleased with the performance, this will absolutely work for an overseas red eye flight or a camping trip especially if you get the solar panel chargers which I plan on getting. One more fyi, the Pilot12 means 12 volts and the pilot24 means 24 volts. So make sure you get the correct one for your machine. Hope this review helps.

Update: Long story short. If you are overseas and it breaks down, you are out of luck.Background: It stopped working in August. Under warranty. They fixed it. I went to South Africa in November. It stopped working. Went into stand-by mode after 10 minutes of use. No longer under warranty. Their tech support page was "under construction." I sent multiple emails to customer service and the company. All were rejected. Luckily, my friends in South Africa were able to help me out with a UPS during the power outages.I travel a lot. Some places have stable power grids. Some places do not. I was in South Africa where we had to deal with "Load Shedding", which equated to almost daily power outages. I connected this to my CPAP machine, and it worked just fine during the entire trip. No issues. No problems. I keep it charged when we had power and life was good. Highly recommend.

The battery worked as advertised. Easy to install, charge, and operate. I've used it camping and it works great. Lighter than expected. I'm very satisfied with it.

Working

Ok this is exciting. I bought this for a flight to Europe and tested it out last night. Turning off the wifi, Bluetooth, heated pipes, and disconnecting the water chamber, I got six and a half hours use and the capacity lights only dropped from four lights (fully charged) to three. It is very, very expensive BUT it is small, light, and looks like it will provide someplace in the order of 24 hours of DreamStation use on one charge. If you can afford it it is worth every penny.

Battery works most of the time. But the level gauge is not accurate. During a test, the battery took 22 hours to used 50% of the charge. And then the remaining 50% under the same test load took 8 hours. For the cost of this item and the intended usage in medical, the usage gauge should be more accurate.

The battery does not come with a charger... but no problem! You use the same AC adapter as what you normally use for your CPAP. I love that. Next, the battery has a USB port. So, it also charges your phone. It can charge your phone and run the CPAP simultaneously. I just used the battery to run my CPAP on a plane... no problem sleeping for six hours, and the battery indicator only went down by one light. Then, I went camping in a tent. One night I slept a continuous 9 hours, and the battery charge indicator once again only went down by one light. If you hold down the on-switch, a small LED lights up, which helps with things in the dark (like tent camping). When you do have power, you can charge the battery and use the output simultaneously... so the battery works as an uninterruptible power supply (UPS). Fantastic product!
