This is neat, but using an off the shelf power bank and keeping it plugged in is going to destroy the battery in a year or two. Those Li-ion pouch cells deteriorate rapidly at 100% charge, especially in a warm environment.
It's better to use a DIY DC UPS with some LiFePo4 cells, that only charges them to 80% or so. And you won't have any issues with power reset.
There's also much more of a fire risk when using Li-ion cells compared to LiFePo4.
