With note that their Max that is supposed to act as a battery for cells as well as a light is not yet in production, as far as I can tell.

The 5v and 12v formats are on a upswing for most electronics, to be sure. The utility of keeping a cell alive under circumstances where a cell network may not be up, though, eludes me. A power down thing, I can sort of see. A kessler/carrington/EMP chipkiller event... no. So I'm thinking the Novas or Maxs for lighting if I want to upgrade from my reliable old paklite 16s.
