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.
