realizing all of my stuff at home is going offline because there's a power outage while i'm away is making me wonder something
what if i cobble together a router UPS (server is already battery-powered laptop)
would a regular phone power bank outputting to a 5-to-9v boost converter work or am i being silly
(i do not want a bulky 110v ac ups)
@squirrel I tried something like this and it mostly worked, but the charge circuitry didn't like having brown outs, so sometimes it'd behave oddly during storms.
@ajroach42 i'm thinking about a very straightforward thing taking a 2-output power back, leaving it plugged into the wall, and plugging two of these into it, one for each router i have https://pt.aliexpress.com/item/USB-DC-5V-to-DC-9V-DC-5V-to-DC-12V-Step-up-Cable-Module-Converter/32832075077.html
