I want to use this as a sort of UPS for a Raspberry Pi to properly shut it down in a car. I was wondering if it’s suitable for this purpose and what else I’d need to accomplish it. Basically, when I turn off the ignition, power to the 12V outlet is instantly cut. I’d want the Raspberry Pi to continue to receive power for a few minutes while it can cleanly shut down. I read in the comments that the device can supply power while being charged at the same time (and I assume there won’t be a momentary drop in output power when the input is cut), but does it automatically start outputting power when it senses input power? I don’t want to have to manually push a button after I start my car, just instantly turn the Pi on.
Thanks!
