Ever since I have a UPS, My pc have 30 minutes worth of energy so I can shut it down properly in case of blackouts.
Once I shut down my computer during the blackout, I will plug my router to the UPS and the router have 2 hour worth of electricity. So I can use internet for 2 hours with my tablet.
I heard if you connect your UPS to a car battery you can have 10 hours of electricity for your pc. Sometimes the blackouts in my area lasts for 7 hours.
