not really recommendable for a permanent setup. with an ups and standard
mains equipment, you will waste battery (and carry dead weight) twice:
in the inverter that generates grid voltage from the battery, and in the
PSUs of your gear that will re-transform the precious grid voltage back
into low-voltage DC. throw out the middle man.
the nice thing about car equipment (as a previous poster has suggested)
is that all the gear is standardized to work at 12 volts dc. many car
radios have line ins these days (for file players etc.). it's easy to
hook up a small mixer here - you should be able to find a cheap one by
the Brand That Shalt Not Be Named or one of the other manufacturers they
steal their designs from - i've seen a few that take 12v dc.
