Question 1

To how many decimal places does this one display for Watts?

Accepted Answer

This EZ model does NOT display how many Watts you device is pulling... It displays how may kwh have been used thus far, to the 1/10th decimal place.  So, when you first plug something in is shows ZERO, since not enough time has passed to show kwh used yet.  This is a HUGE feature left off this device.  For me, I want to plug something in to a meter like this and be able to instantly see how many Watts the device uses, and this EZ meter version does not do that.

Question 2

Can it be set for a period of time (such as 24 hours) and record usage only then?

Accepted Answer

Yes, this records the total power used by the device whether it is on or off or any mix.  You just need to go to the screen kwh used.  record the beginning # and at the end of time period (say 24 hours) record the end #.  that is how many kwh it used.  I used several of these for months to record the A/C use in our shared apt and paid the landlord for the a/c used so they don't complain about my electricity used.  great device.  now however, my apt has a 20a a/c wall unit.  while you could get converter to regular 3 prong, not sure if this unit will go to 20 amps.Others who said no are simply ignorant of this devices menu.  It ALSo shows, when on watts menu, the watts used when a device is running, or is off.  so you can see how much your a/c or toaster oven or giant screen tv uses when on, or off.It also keeps the power kilowatt hours used even if unplugged or power goes out in its internal memory.  so you can simply record the kilowatt hours at the begin of a month, then at the end of the month, subtract and multiply by your cost of electricity for the total $ / month the device uses.The dork who was our landlord at the time thought his electric water heater for tea was less expensive to use than nuking a cup of water for a minute to heat it up in the microwave.  popped this device on it and they were almost identical in total power used to heat a cup of water.The same idiot who was complaining about this left his rear projection tv on when he wasn't around, and they use alot more electricity than today's flat panel screens.If you want to record the power usage of some device over time, you'll want to plug this device into a short extension cord.  if you plug it directly into the wall then you have to lie down on the floor to read the kilowatt readings.  I just put the readings into a spreadsheet when I was recording monthly electricity usage.

Question 3

does this work on 220v 60hz house outlet

Accepted Answer

As others have said, no, it does not. However, the Poniie PN2000, which you can find here on Amazon for ~$25, WILL do 110-230V input up to 16A. That's the one I'm probably going with...

Question 4

Is this model 220v (Non US) AC compatible? If not, which model is? Thanks in advance

Accepted Answer

This is a 120-volt meter. I recommend that if you want a plugin meter than can handle 240 volts you look one for the appropriate electrical receptacle on the front. This one clearly has a standard 120-vold outlet receptacle.
