In the example you show here are the numbers.

The top line represents how many watts are being used, that is the total power of everything you have plugged in.
Once you have the total power drain on the UPS (batteries) the second line tell you how long until the UPS will last (under optimum conditions)

For a example, most hair dryers draw 1500 watts. If you look up 1500 watts...oops not enough power.

Another example: My laptop draws 120 watts, so that would be just under 7-1/2 minutes. Great...oops forgot the Modem...and the Wireless Router...hope I don't need to print anything!

So, you can see how it all affects the length of time you can stay on-line.
