A Raspberry Pi Zero and Pi Zero W (abbreviated here as PiZ) is a small size computer tethered to the wall power outlet. It needs the power via the micro-USB cable to operate. When PiZ needs to be moved from one location to another, it needs to be shut down and rebooted. If the power fails, the PiZ shuts down without a proper shutdown sequence, sometimes with catastrophic after effects. PiZ-UpTime provides clean, stable, reliable uninterruptable (UPS) power to PiZ. Pi-UpTime provides power mobility for PiZ.
