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.MikeInPA wrote:So far:
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.
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.
