The inverters exist, The multi chargers exist, every UPS on the planet has the tiny bit of switching technology to switch between charging the battery and smoothing voltage/providing backup power.
minimum 2 port UPS, Allows you to throw in another charged battery without loosing power. great for everyone these days relying on wifi/internet to keep us connected. plug in your router and/or modem or whatever else you need to keep going in a crises
