Fedi people who know electrical stuff: I have a UPS whose capacity is described as _both_ 650VA _and_ 390W. I have no clue how to interpret this: surely VA and W are the same thing? Also, how can I use these numbers to determine how long its battery can power a device with a given wattage requirement?
