When you look at the math (as you have) it seems almost certain to be a scam. ResMed has a Technical note [0] on powering one of their devices form a battery, while product efficiencies can vary they are recommending ~30 Amp hour batteries for the 20 cmH20 this device is claiming to provide. It amazes me that indigogo doesn't do something to stop this sort of thing when it gets to be such a well funded project (I'm sure other platforms are guilty of it too).
