How to protect RPi from abrupt power down?

Hi

RPi needs to be shutdown gracefully with commands.

However, in the case where power outage is frequent or if we intentionally want to allow users to plug off RPi at anytime, do we have any solution for it? For example, to have a power bank sit in between and when power outage is detected the shutdown command is immediately issued?

Have anyone tried to invent a system like this? Please share your ideas how you actually implement it?

Thanks,
Narin

What are you trying to protect?

I don't see why the Pi would be harmed by an abrupt loss of power.

It might cause SD card file system corruption if the card was been written as the power was lost. You can minimise the chances of that by minimising writes to the SD card.
