I've never heard if a jackery before but they sound neat but for $600 and up they better work.
but how many amp hours do the various ones provide. Yes, they have some neat features however.

However what? The Jackery was just used as an example, there are many others out there for cheaper and I was just giving an example of what can be used. I have used a smaller battery on my Resmed 10 that lasted 8hrs on long flights without a problem of course without the humidifier and heated tube on.
You can easily figure out the amp hours they produce.
