Shopping UPS Units - How do I calculate how long it will last?
I'm shopping a UPS unit for a generic device. Let's say the device pulls X amps. Is there a quick-and-dirty calculation that allows me to calculate how long a given UPS will supply my device?
I'm seeing units associated with UPS units of "VA" (volt-amps) and Watts. I'm a little confused, isn't a Volt-Amp equal to a Watt?
