I just received a DC female adapter for a small battery pack that I have had for some years now and I had success with it. It is the Tekkeon myPower ALL 3400 Universal Rechargeable Battery (now discontinued - but a newer model is available). http://www.tekkeon.com/downloads/UG_mpALL_33_3400.pdf

I connected the cables and set the voltage to 12v. The 60 series powered up and ran successfully. It also ran well when I bumped it up to 14v and also when I lowered it to 9v.

I am going to use this older 50Wh or so battery tonight and see how it holds up. If all goes well I plan to order the Tekkeon myPower ALL Plus MP3450 R3 External Laptop Battery Bundle http://www.tekkeon.com/products-mypowerall.html which will give me 100Wh in the two mated battery packs and I will also have my older model 3400 as backup. You can also carry as many of these as you wish when you fly since they are under the 101Wh International Dangerous Goods limit and these packs can be used to power multiple devices and voltages.
I did order and have used the Tekkeon myPower ALL Plus MP3450 R3 External Laptop Battery Bundle and it works very well. The dual battery pack is rated at 116Wh (58Wh each). Separated they are under the 100+Wh restrictions on some airlines so you can carry as many as you wish. I picked up the two batteries for $203 including shipping. I like it because it runs my 60 Series CPAP as well as being capable of running an endless variety of equipment at various voltages.

With the setting on the battery at 12 volts, I used my 60 Series CPAP with C-Flex at a pressure setting of 12 for 6 hours. There was about 25% battery capacity left. I would then think I would get about 2 more hours from it, for a total of 8 hours running time.

With the setting on the battery at 9 volts, the CPAP ran just fine at a pressure setting of 12 for 8.5 hours. There was about 25% battery capacity left. I would then think I would get about 2.8 more hours from it, for a total of around 11 hours of running time.

I have read that the machines work harder at airplane cabin pressure of 8000 feet, so I hope I will get 8 hours while flying and running at 9 volts. I plan to report back on this at the end of April.

On a side note:

When I tried to run the CPAP at 7.5 volts the machine was struggling and wouldn't run. When I bumped the battery voltage to 16 volts, I received the "service required" error message that I received when I used the fully charged CPAP.com battery. It's too bad I never checked the actual voltage of the CPAP.com battery before I sent it back.

MikeInPA: I believe the person you spoke with from Qantas did not understand their own policies. If you look at the link above you will see they only have limitations on Li batteries. In other sections they allow up to 300 Wh for wheelchairs. As a medical device, the airline is required to make arrangements.

For Non-Spillable Batteries:

Regulations require the batteries to be 12V or less and 100Wh or less and a maximum of 2 spare batteries may also be carried.

Unfortunately at 12V and 14.4Ah, the sealed lead acid battery pack exceeds this restriction at 172.8Wh.

Concerning a CPAPSupplyUSA battery: http://www.cpapsupplyusa.com/CPBPack-CP ... yPack.aspx the CPAPSupplyUSA rep stated that "it will not run the 60 series we have tried."

Some of the other companies that I have contacted are sure that their batteries work with the 60 series but are unwilling to waive the 15% restocking fee since many folks use the batteries for one trip and then return them. I am not willing to risk 15% every time I try a new battery. One company said they would waive the fee but they didn't have a smaller battery to fit my requirements.

I was able to use my 60 series in my car (engine off) and in an auto jumper cable pack DC sockets. I am not going to try using the 60 series in my running car because the instructions for the adapter cord state "When DC power is obtained from a vehicle battery, the device should not be used while the vehicle's engine is running. Damage to the device may occur."

I have been trying to follow this thread and I think the issue is the lithium battery packs. Having built a few lithium battery packs for my Transcend and learning some facts on the way. Some clarification, a fully charged 14.4 V lithium battery is 16.8 V. When you require a 12 V lithium battery pack it is really 11.1 V and fully charged its 13.1 V, there abouts. If the PRS1 60 has a problem with 16 Volts plugged into it you need to get a 11.1 V battery pack not a 14.4 V pack. Hopefully the PRS1 can handle that voltage level without doing any damage. I use a 12V 22ah SLA battery for my PRS1 460 and get three nights of use without overly discharging it (humidifier off). I would probably would have problems trying to get the lithium packs I built onto a plane, since they don't have any markings. The Transcend packs are pretty expensive.
