You can get a SLA (Sealed Lead Acid) battery in various sizes, and they put out 12V. They could easily run for several hours on a single charge. Don't bother tying to make a charger (harder than you think!) just buy one, they're pretty cheap.
An example of a battery https://www.amazon.com/Verizon-PX12072-HG-Powerstar-Rechargeable-Terminal/dp/B00V93WVPO/ref=sr_1_54
which is rated at 7.5Ah, so it can deliver say 500mA continuously for around 15 hours.
Make sure you get a smart charger, like https://www.amazon.com/Battery-PeleusTech-1A-Portable-Maintainer/dp/B01822CSA2/ref=pd_sbs_23_2/132-4805477-2123568 which does trickle charging and has auto cutoff, etc.
That said (and I agree), here's a hypothetical for the EE crowd to ponder...
They all use AC Adapters. For example, the Kickr Snap uses a 12v 5A adapter, so couldn't you run it off of a $15 battery, like this? Yes, you would have to fit your own custom wire, and yes, you would have to recharge that periodically at the house (or maybe via solar).
And yes, I realize that this risks blowing up a $500 trainer, hence the hypothetical classification.
This is the charger
