    Comments about P3 Kill A Watt Ez:

    This Watt meter works great for checking the power usage and cost for any appliance or equipment using electricity. Hook up this meter and it will give you the time elapsed and KW hours used and the cost for the minute, hour, day or month any tool or appliance uses. It also will give you an accurate reading for the voltage coming out of the wall receptical. This meter will do all the calculations for you. I have used this on every tool and appliance we have in the house and garage. The meter results take all the guess work out of trying to figure out how much power a tool or appliance actually uses. This is a tool I am glad I bought. It is well worth the money. DON'T try to use this meter to check power usage in a line with voltage greater than 120 volt or greater than 15 amps. Use this meter in dry conditions only.
