do you know how to compute elec consumption?

[woohoo]

This gadget would be handy but I think it only works on 110 volts.

It *is* handy. My neighbor has one. Too bad it only works on 110V (120V). All our efforts to search one that works on 220V only found us some INDUSTRIAL-grade ones.

... but today, this same neighbor showed me his newly-purchased VoltCraft Plus Energy Logger 3500. He bought it from Alexan for Php1,500.00 but their website doesn't list it.

But I found it on the internet anyway: http://www.conrad-international.com/?article=125323

I'll buy one myself later.

If my memory serves me right, here are the formulas:

1. number of watts / 1000 to get kilowatt per hour consumption
2. multiply by number of hours used in a day
3. multiply by number of days used in a month
4. multiply by cost per KWh (depends on the current rate established by your provider)
