12 volt output will eventually damage that router, better to go for 9 volt, i myself use that router by 9volt and also it has 12v and 5 volt usb output from my mini readymade ups.
Here is an example, make a video where you show people how to buy circutboards, batteries, enclousure and build top of the line power backup that they can sell online to charge their 5v products, then do one more with 20v for laptop charing.
