I also found out that Kill-a-Watts don't care which direction power goes through them. If you reverse the flow of electricity..... well, I guess that's the point of AC, it's ALWAYS going back and forth... the Kill-a-watt still works right.
However, by using a fancy plug coming out the back of the UPS, I can no longer just slap a Kill-a-watt on there and track the total energy going through it!
Doh!
