I was looking for a basic UPS which would allow a Pi to keep running for
a few minutes if power were lost or while the Pi was being transferred
from one mains socket to another. Ideally, it would tell the OS to shut
down, if necessary, and would restart the machine when the mains came
back online.

Well, I came across the following one which looks excellent. It seems to
do all I wanted and the battery can be upgraded to give longer life.

Any opinions on it? And as it is out of stock at the moment, would you
recommend any similar UPS?



Some of the description:

The UPS PIco will automatically shut-down your Raspberry Pi if there is
a power failure, and can be set to automatically monitor and reboot your
Pi once power has been restored!

When the cable power on the Raspberry Pi is absent, insufficient, or the
device detects a power failure, the UPS Pico automatically switches to
the unit’s battery source. The module then continues to check the
voltage on the Pi and switches automatically back to the regular cable
supply when power is once again available.

The UPS PIco is powered and the battery pack intelligently charged via
the GPIO pins on the Raspberry Pi, so no additional cabling or power
supply is required.
