Its not accurate. I tested with a known load over 100 hours. I plugged in a 100 watt bulb and left it on 100 hours, which should give me 10000 watts or 10 kilowatts. According to this meter, it said I used 80 kilowatts, that's that's 80,000 watts. I'd say that's just off alittle. They advertise + or - 2%. That's more then 2%.

Avoid this product. Its junk.

The user interface is bizarre - keep the manual handy, because random pushing of buttons can land you in some strange places.

Their customer service confirmed that there's no way to turn it off. Maybe you should just leave the battery cover off, and the battery out when not in use?

All I wanted was something to measure cumulative power usage. There are other meters that do this much more intuitively.

(as for calibration: I ran it for 2.5 hrs monitoring a light with a 60w lightbulb, it measured .163kWh, which comes out to a 65.2 watt bulb. Whether the bulb was straying or the meter, I don't know.)

I needed a power meter to locate the source of a hugh increase in energy consumption. I found this meter to be easy to use and accurate (me and my EE buddy ran a series of power factor tests on the unit and it's accurate within the stated specifications, even when measuring "lossy loads").

This is a handy tool to keep track you appliance's energy consumption. Your friends will likely want to borrow it.
