Note:
Data given are the average values, not the minimum values.
A UPS is not designed to provide continuous power, merely a window period that allows a computer or other user to finalise the work at hand and shut down. It's ability to do this is dependent on the number of devices connected to the UPS.
To establish what you can and cannot connect, calculate the total wattage you need to supply and ensure that the UPS you purchase meets that requirement.
