Making sense of Kill-A-Watt readings
bought a P3 Kill-A-Watt meter, left town for a couple of days and left it plugged into my tech cluster to read kWh (380 watt P4 3.06 GHz desktop, 160 watt P4 1.6 GHz desktop, 19" LCD, 200 watt Klipsch 2.1 speakers, USB 2.0 hub, Epson inkjet, wireless router & cable modem all plugged directly into a surge protector that plugs directly into the meter).

after 5 days it read 28.50 kWh (and yes everything is left powered on including the two computers and printer and not used in those 5 days).

is 171 kWh a lot of energy for a month (28.5/5 = 5.7 x 30 = 171)??

(that's roughly $12 a month* just for this stuff running 24/7, in case u were wondering... i'm not sure if $12/month is a lot either cuz i just moved here, Seattle, and don't know yet what electricity runs here for a one bedroom apt)

TIA

* = got state's residential cost average from http://www.ppinys.org/reports/jtf/electricprices.html

What's the question? Your readings look reasonable, my main machine and the router, switch, and VoIP box chew up about 225W when idling, which would be 24KWH in the same five days.
