USB cord to power eflow

[xosder22]

I am trying to figure out how to power my eflow with my mophie external phone battery. I have found a usb to DC 12v converter but I can't seem to figure out what size barrel plug is on the eflow. Anyone done this?

It's my impression that all eflow nebulizers run off 4 AA battery cells in addition to the external AC power unit.

Have never attempted this, but would be curious to know the outcome. Since starting to use (high quality) rechargeable AA batteries I have never used the wall adapter again, as it is 100% portable and I seem to get a few days' treatments before needing to swop batteries. If you need the recharging to be portable, how about a workaround - an AA battery charger that charges from external battery through usb?

I don't know what type of eflow you have, but every one I've seen has a built in chamber that holds 4 AA cells. I get at least 20 "treatments" from one set of Costco (Kirkland) AA alkaline batteries.
