- The Kill-A-Watt P3 4400 is the ubiquitous energy measuring device for the last decade or longer. It can measure Volts, Watts, Amps, Power Factor, Volt-Amps, and more. It will record duration and overall usage as well. I'll show you how it works and how to measure two different kinds of lights.

@The Net Guy you say this is old tech and that there is something better but don't even say what it is.
Oh my apologies. This was a clip out of a larger show. Emporia energy makes smart wall plugs that can track and log usage over time - and give you on/off control. Love their stuff!!
Thank you for this video, can you make a comparison with Smart plugs that are wifi connection and app logger!
Good question. Check out emporia energy for their smart monitoring plugs - my favorite!
How do you check the inrush or The Surge of a device on this kilowatt unit
Unfortunately tools like this aren’t great for that. A more advanced meter is probably needed. This is more for average, max/min and values over time.
Do you know about the P4460 model also ?
I have questions about that one.
Maybe you (or someone) can answer my question...I have a very similar device I bought to calculate power needs of various items I might want to plug into my generator in a power outage. I have a 7 cu ft chest freezer that says on the label that it is 1.7 AMPs @ 115V. If you multiply AMPS x Voltage, you should get WATTS required. In this case that would be about 195wt. When I plug the freezer into the monitor, I get very different numbers (??) The monitor displays .65 AMPS (instead of 1.7 AMPS), and it displays 60 watts (instead of my calculated 195 watts). Where am I going wrong here?
That's the maximum it can pull, it should generally pull less than that (unless it's been completely defrosted?).
@@isaacressler8177 So...under certain conditions, the freezer may pull up to 195w continuous? But this has nothing to do with surge watts (when the compressor first kicks on)? Correct?
Power factor is your missing link. Volt-amps is not quite the same as power, despite the same type of unit.
I have a Corsair AX-760 760 W 80+Platinum rated power supply for my PC, and it features PFC iirc. Would this be able to show an accurate measure of what a PC using a PFC PSU is actually drawing? I know not every battery backup is usable w/this kind of PSU. Thanks.
Yes, it’s not going to be perfectly accurate for spikes due to capacitors and such, but I general it is very accurate at net usage at the wall and over time 👍
@@TheNetGuy Ok, thanks. I've been considering getting one of these for awhile and will use your link when I do shortly.
Can I connect my ups backup, with my 4090 pc, monitor, speaker, in this device?
