Please get a real profile picture, I thought my eyes had finally quit on me, but no, it was that crappy blurry mess. Please, think of the eyes you can save.
Power banks can be incredible depending on your needs. 1) I have a 100w capable one that can charge my laptop. 2) Same one can also power my soldering iron (though is overkill for it) 3) a BIG power bank I have with an AC outlet on it can power my desktop weed vape during a power outage
Network switch, two VM hosts, a raspberry Pi, wireless AP, Zigbee coordinator, and two NASes. 17 minutes, enough time to go "oh shit the power went out time to start turning everything off"
