Kill A Watt Connect P4498 Electricity Usage Monitor Power Consumption Meter with Two Piece Housing and 35 Inch Cord for Easy Use

My husband made fun of me when I first purchased this and now he is asking to move it into his office. 10/10 recommend. I am hunting down what appliance is causing my bill to be so high and the Kill A Watt Connect P4498 is perfect! Love the remote display, although it would be nice if it was maybe a foot longer. My suspicion that the fridge is broken was debunked, is not the cause of the bill, and it actually meet the energy star rating that it claims. Love it!!

It's not much larger than a regular plug. The cord between the plug and the meter is just long enough to get the meter out where it can be read but not so long that it gets in the way. The instructions were easy to follow and you can set the rate that the power company charges very easily. It does take a few minutes of use before it can give most of the cost for the device that is being measured.

We used these back in college (14 years ago) in an Electrical Engineering class as a test to their accuracy versus a traditional clamp meter, and they work pretty darn well. I was having an issue with my desktop computer pulling too much power too quickly and popping a AFCI Breaker for my room. I needed to confirm the power pull of my system, and using this device I was able to prove that it was well under the Circuit Breaker's capacity at all times - ultimately getting the breaker replaced in the panel!

Only 4 because the rate only goes up to $9.9999. Duke power is at $12.64 per kwh.

A nice way to monitor the instantaneous and long term power usage from a standard 110V US power socket. It's also a nice way to quick check power stability (Voltage and Frequency). Power usage can be viewed in multiple ways, current, kiloWatts and kiloWatt hours. Plus you can enter a cost per-kWh and with a few hours of monitoring can view the cost per-day/week/month/year. It is only a numeric LCD display so you have to judge trends, peaks and dips for yourself but it's fit for easy checking of power-usage for working devices.

Very easy to install and operate, the cord helps with monitoring appliances like your refrigerator. If you buy it, you will be running all around the house measuring everything that draws power. Strongly recommend purchasing this item, the price was reasonable as well.

Great gadget! I use it to monitor a small Bitcoin miner and it seems to work well. It’s easy to set up and the detachable screen is great for “remote” viewing.

I bought 3x of these to monitor the power consumption of 3x window Air Conditioner's plugged into a dubious circuit in an older home. Before buying these, I owned a typical Kill-A-Watt for a decade and I loved it. It had only ONE design weakness, and that was the need to to crawl behind furniture on your hands & knees with a flashlight just to read the LCD output. So the idea of a Kill A Watt with a detachable/extendable LCD monitor that could be placed in a visibly accessible location sounded to be the perfect solution. Ah but silly me. In all my excitement I did not read the product page well enough. About 8 years ago I purchased a competing product: The Rosewill RHSP 13001 Load Meter, which is just a rebranded TrickleStar PM_891EM-US-W. When I saw the P3 P4498 offered on Amazon, I assumed I'd be getting something similar; Not so. Turns out there were 3 subtle differences between the Rosewill/TrickleStar offering and the P3 Kill A Watt P4498, that made them seem like 2 different devices. (1) Aside from the advertising, the Kill A Watt P4498 has a 32" monitor cable (NOT 35".) This makes the Kill-A-Watt LCD monitor cable a full foot shorter then the Rosewill/TrickleStar. And that just-plain-silly short cable largely defeats the point of the monitor extension since it won't reach many table tops, let alone a dresser if the outlet is near the floor. (2) No surge suppressor. Albeit, this feature was not advertised, and not truly necessary, BUT the Rosewill/Tricklestar included surge suppression, and since I am guessing that many folks will end up using this device to monitor the power draw on sensitive devices, like computers and audio equipment, it seemed odd one was not included. (3) Price. The Kill A Watt P4498 seems pretty pricy for what it does. I found the competing product to be much more reasonably priced. This is MY subjective opinion; you can decide for yourself. But in the end... In-spite if this, with the use of some short extension cords and nylon cable ties, I have pressed all 3 of these into service, and they have been meeting my intended vision. I hate returning stuff, so I will learn to live with these guys and make them useful But honestly, had I known I could have acquired 3x of the TrickleStars at other sellers, I would have purchased those instead. Even though this is a pretty negative review, I really need to re-assert that all my previous experiences with P3 "Kill A Watt" products have been excellent. The P4498's were disappointing, but I guess no manufacturers can be expected have perfect batting average all the time.
