How Much Runtime Do You Need To Support Your Attached Devices?

That depends on what you plan to back up with your Uninterruptible Power Supply(UPS). Runtime refers to the amount of time a UPS is able to power its attached devices in the event of a power outage. The more devices you plug into your UPS, the less runtime it will have, so it's important to make sure your UPS is only providing backup power to your most critical devices.
