12 volt adapters

[roadkingrick]

So ive been on a machine for 12 years or more and I love my machine, but... I bought an adapter ( 12volt ) cigarette plug for camping and travel. They are expensive. I am a resmed user so Ive purchased on for an s8 then an s9, now im on an s10 and so is my wife. There has got to be an adapter for the other power bricks so you can use them for different models, same brand. 85 to 100 bucks is crazy when ive already got two of these that have little to no use. Anyone got a solution or ideas?

There is no cheaper solution that I know of. This is simply an extra cost of dealing with ResMed. If you use Philips you'd still need a special cord, but its only $25.

You could possibly sell your old adapters to recoup some cash.
