To update everyone. I finally opened up the Intex UPS and connected two wires directly to the battery points.
From that I connected a car 12v shell connector (female) such as this one: *www.earlybirdsavings.com/picture/GCR025/view-GCR025-12v-Female-Car-Cigar-Cigarette-Lighter-Socket-Plug-Connector-Plug-Cable-1.jpg
And then connected a car charger extender (*tse4.mm.bing.net/th?id=OIP.M59f2140ef8d750b99fbd201b5df00878o0&pid=15.1) to the same.
From the extender, used the 5v USB to power the ADSL router, by splitting a USB cable (*www.instructables.com/id/How-to-power-nearly-anything-off-a-USB-port/).
For the wi-fi router, which takes 12v, directly powered using cabled from the extender.
Still have 2 slots in the extender, will use them for charging laptop and mobile phone if needed.
So, the setup is complete and I am powercut safe, with 12+ hours of battery backup for most devices. This however, could have been done by any UPS and not just this Intex one.
