Hi, I just got a new Airtel broadband connection with Beetel 110 TC1 modem (ADSL2+Router) with input 5v DC/1A. I would like to go for a UPS to work uninterruptedly due to power failures. I plan to use the UPS only for the modem. I need a UPS which keep the modem on for 3 hrs. Please someone suggest which capacity of UPS I should go for?
