Can't resist asking what you're doing. In most cases a few minutes outage
isn't a big deal, just wait for the Pi to reboot. I've depowered mine many
times with no ill effect, except maybe a prolonged fsck on restart.

Martin's answer seems to be as close to "no building" as is practical.

You could use something like Amazon's Jelly Comb car charger with a
regular 12 volt battery and a separate charger. You'd still have to buy
cables, wire the USB charger to the battery and hook up the battery
charger. By the time you're all in I'd expect the cost to exceed $100.
This approach avoids custom USB cables but certainly isn't plug and pray.
