Airmini battery recommendation

I'm sure this has been covered before. But I'm looking for a battery that will power my Airmini when I travel. No long flights so I don't need anything that's airline approved. Just need something that's reliable. Thanks

try using Google along these lines-"CPAP talk.com battery for air mini" which is where I found the link I posted.

s/b more I just didn't pursue it past what I found above.

good luck!
