How long will this UPS power my system when the power goes out?

Runtimes of any UPS will vary based on the amount of power required by your connected devices. The LCD Screen on the Back-UPS Pro model will display the estimated runtime based on the current power load of devices plugged into the UPS.

Will the UPS automatically switch off from the battery backup when power is restored?

Yes, when adequate power is restored to the UPS and is within the operating voltage range of the UPS, it will restart online operation.

Will this UPS provide continuous power in the case of a power outage?

This Back-UPS Pro instantly switches to battery power, when the main power goes out. The average transfer time is 8 milliseconds, and most connected devices do not experience any interruption in power.

Can I plug the UPS into an extension cord or does it have to be plugged into a wall?

In order for your UP to get the best power available, you should plug it directly into the wall receptacle. Plugging your UPS into a surge protection may cause the UPS to go on battery more often, even if the main power has not gone out.
