Less than 30 minutes if they’re both on. A fan sucks a lot of power
Sorry, there was a problem. Please try again later.How long it lasts is based on how much energy each of your devices consume. Look on the ID tags of each and look for "Amps" or "A". Add the two loads together. Then check the "Amp Hour" rating of your unit. Divide the unit amp hour by the amps consumed and you get how long (in hours) the loads will operate. For example, if you have a 100 Amp hour back-up and your loads add up to 10, then 100/10= 10 hours. It is not a bad thing to test once and a while to exercise the batteries. Unplug your ups and operate the loads. Then you will know for sure how long the UPS will run your stuff.
Sorry, there was a problem. Please try again later.Assuming your TV is 300 watts or so, I'd say 20-30 minutes.
