Does anyone have a recommendation for an uninterruptible power supply (UPS) that meets the following requirements:
- Safely shut down a Raspberry Pi 4B following a mains power loss event (ideally with a configurable qualifying time) and transition to battery power.
- Automatically boot the Pi, following restoration of mains power.
- Can be a HAT or external, but must have a form factor smaller than say: 150 x 150 x 150 (mm)
- Optionally: something that won’t require the replacement/destructive-alteration of my Argon One case.
I’m pretty sure I could use an Eaton 5S to get all but the form factor requirement.
It seems like the DFRobot UPS HAT won’t meet the auto boot requirement.
