   It's certainly the simplest solution from off-the-shelf parts.   
   Standard dc-dc converter, standard battery, standard charger.   
   No need for a handmade line power loss detector.   
      
   Efficiency won't be great. For one, or even several, Pis   
   that's not a problem. But it will likely be somewhere close   
   to $100 for a halfway decent battery and charger.
