I have not tried any of them as I dont go on long enough flights etc to warrant getting one of these.

Thanks anyway. I got a good deal on an EX8000. This should work out fine. I still have a small, lower capacity Li Kennsington that I got as back-up for my phone but hand't paid attention to the beefier units. I'll still drag along another amp -- because only the paranoid survive.
Hello? I said I was looking for a way of extending battery life on a 12-20 hour flight(s). Plenty portable enough for my intended purpose. Run the power down and add another layer to the rig for the back-end of the trip. You evidently do not get out enough.

The recommendation was made based on very long travel when recharging is not see easy of an alternative. It is plenty portable.
It has absolutely no problem driving 32ohm phones to there peak performance.
