Sugggestions for Battery Backup

Looking around for some suggestions for battery backup for a ResMed S9 VPAP Auto with H5i Humidifier.

I'm not really interested in a Deep Cycle Battery / Inverter Solution ... I'd like something smaller and more portable.

If anyone can suggest some that I should look at it would be appreciated.

Thanks .... Fredf

It's not cheap and I don't know enough about this stuff to look to see if there is something similar out there (very likely there is) but this would work. It says we can use the humidifier with it. That would be a huge plus for me.
Most of the DIY battery things don't offer enough power for using a humidifier and I would rather not sleep than not use my humidifier.

Smaller and more portable is good, but it's going to be considerably more expensive, and/or have a shorter lifetime.
