So my power's gone out a couple of times in the last year for 2 to 3 hours. It always happened at the worst time when my phone was running low on juice, so was kinda sat like a lemon waiting for it to come back on. I've had a bit of warning this time that they're doing work on my power lines so the electric will be off for 8 hours for one evening next week, so bought myself a ups. I'm not expecting it to power my TV or anything, I just want it to power my router so I can watch things on my tab. It's still charging so haven't been able to test it out but am I right in thinking amps makes more difference to power consumption than watts? Never been able to find the capacity of the batteries online but I think it's a 7-9ah. The box says it'll run an entry desktop, 22"monitor and modem which is 40 watts for 80 minutes. I'm guessing 2 of those run at 1 amp each. I've done my maths on my router and it's 46 watts. So will my router run the ups down in less then 80 minutes even though it's only 0.2 amps?
