Poniie PN2000 Plug-in Kilowatt Electricity Usage Monitor Electrical Power Consumption Watt Meter Tester

Meter is pretty easy to use. As mentioned in other reviews, the accumulated time (in minutes) is calculated only during the time the load is on (so if you you’ll measure the consumption of a lightbulb, the time only accumulates when the bulb is ON). This by itself is a logical and useful feature but it would be nice if there was also a second accumulated time display for just when the device is plugged in the wall. Now you have to record the time the measurement started when measuring a load that does not have a small standby current. But altogether this is not too big of a deal. Nice feature is that it keeps the measured data in memory so they can be viewed at another location. Another Pro is the fact that it’s possible to keep the backlight on all the time. Very handy if the device is plugged in a dark area (eg behind my refrigerator) and you want to peek in from time to time to see the progress. Haven’t check the accuracy but based on the readings it does for frequency (varying between 59.98 and 60.02 as expected) that seems pretty good. Con: The actual reading displayed is in easy to read large fonts. The indication of what it is unfortunately not. The indication kWh, Amps, Cur etc are in the tiniest fonts. Why not make that larger, would be a great help for half the population that needs reading glasses. Pro: The supplied extra cord is very handy. Excellent idea! All together I’m quite happy with this and would recommend it. Long term I don’t know yet, only had it for a couple of days.

Plug an electrical device into the Poniie watt meter to measure the wattage, current, or voltage flowing through. You can also set the Poniie to measure the amount of kWh used over a period of time, good for determining how much an electrical device costs you during usage. The display on the Poniie is of high quality and brightness, making it easy to read. Product also comes with an extension cable of about a foot long, so that you don't block multiple outlets in a wall or power strip. It additionally comes with an operation manual. Ultimately, the Poniie watt meter does precisely what you'd expect, and perhaps a little beyond that, at a high level.

The Poniie PN2000 is an easy to use and simple device after you read the instructions and various customer reviews in order to figure out the menu settings. The device is well made, the digital read out is easy to read, and it works just as described. From the owners manual: The device can measure Watts (active power), Current (true RMS), Voltage (true RMS), Frequency, Cumulative Time (with hold over circuit memory), Electricity Consumption (with hold over circuit memory) and Power Factor (as Watts/Vrms*Arms). The important numbers to figure power being used by an electrical device are the "cumulative time" and the "energy consumption". You plug the meter in line with the device you want to monitor and then simply divide the cumulative time (this being the "stopwatch" time that the device is pulling power - if the electrical device is turned off for a while the timer does not keep adding minutes to the clock and picks up again when the device is turned back on, by the electrical consumption. The time is given in minutes so we find it easiest to figure out how many kilowatts were used by "the minute" and then multiply times 60 to get the power used in a kWh (kilowatt hour). For an item like a refrigerator that cycles on and off constantly you might want to leave the device connected for a lengthy period (perhaps 24 hours or longer) in order to get a more accurate power use profile as it cycles on, then off, then through a defrost cycle, and so on. Simple "on or off" devices might only need to be monitored for a half-hour or even less to find out the energy consumption. Unfortunately, like many of Amazon's sellers these days, the Poniie PN2000 seller sends the buyer e-mail asking them to write a review of their product if they like using it. E-mail from sellers requesting the purchaser write a review is what has ruined Amazon's best feature, and those reviews are always suspicious as not only no. Too bad that the seller doesn't have enough faith in their product and has to prompt buyers to write a review. To make it simple we divide the monthly electric bill total by the number of kilowatt hours used found on the monthly bill to get a per hour kW price, and then multiply that number times the kWh for the device we were monitoring (we're currently paying 0.12 cents per kWh).

For me, a valuable feature is the ability to turn on/off the display backlight; I like to leave it on when testing, otherwise it will turn on when you select it and stays on long enough to get a reading then turns off. The light blue backlighting (when on) provides excellent contrast with the readings. The only negative comment about the display is the very small data identifiers (watt, cur, volt etc.) which makes reading them challenging more than a few inches away from the display. However in all fairness, this can also be said about many similar monitors. This monitor seems very accurate. I tested it using a resistive load (incandescent light bulb) of 100, 200 and 300 watts and the readings were constant so comparing the observed voltage, current and power correlated closely with the calculated power (voltage x current). If you are testing an inductive load such as anything with an electric motor, the displayed values were not as constant when viewed individually; they were constantly drifting within an expected range. If you attempt to measure reported verses calculated power under this circumstance, the observed voltage and current will not be correlated in time because you have to cycle though the selector buttons to read the values. The more the individual values vary the more the calculated power could vary and you might assume that it is not reporting accurately. Test it with a resistive load if you want to determine power measurement accuracy. It has other features that provide valuable information if you want to determine how much power a device is using over a protracted period of time, such as a refrigerator. From that you can determine the cost of the energy the device is using. Overall it seems to be put together well and I especially like the inclusion of a short extension cord that allows you to move it a bit closer to you when reading and as an aside, that also allows you access to both sockets on the receptacle when the monitor is plugged in. I found the instructions clear and easy to follow. If you are looking for a good electric monitor, I can easily recommend this model.

I only used it once, but if it holds up I'll be happy with it. I have a dedicated 20 amp circuit for an attic fan that broke years ago. (My house was built in 1959 so it was built with a furnace and and attic fan and not ac) I repurposed the switch in the hallway, reversed it into the ac closet and used it to power my subwoofers. I have a hifi stereo. I wanted to also run my 100 watt per channel vintage amp on the same dedicated circuit so it wasn't sharing a line with lamps, etc. I put a 15 amp GFCI and 3 prong outlet on the d. circuit, but the GFCI was popping. So I bought two 20 amp industrial spec GFCI's in there and wanted to see how much power my stuff was drawing. I used a wet/dry vac and a regular vac to make sure it was drawing lots of power and not popping. It worked great and I know my stereo equipment isn't drawing as much power as those vacuums. This thing has the highest power rating for the best price and reads watts, not just kwh's.

I got this initially to monitor voltage at various times of day. Over the space of a few days, I found it varied from 122 volts all the way to 126. Also learned that I wasn't getting 60Hz, which wouldn't be a concern for most folks because not many people have a turntable with a motor whose speed is dependent on line voltage and frequency, but I do. The variations this product revealed caused me to purchase a dedicated power regenerator designed specifically for the turntable. And yes, the turntable speed is rock solid now. Anyway, the meter is very easy to use, since you can just plug it into the wall or power strip and if you are intending to measure power consumption of a product, just plug it in to the meter. If there's anything about it I don't like, it's that the backlight has a timed auto shutoff I can't disable. I was taking photos of the readings and often had to hit a button just to bring up the backlight.

To start, because there are many of these for sale in many different price points, let me clarify that the 5-stars is for meters at this price point. If you are looking for the best quality meter available with every function, you'll need to look at companies like Fluke (and also expect to pay $2000 - $5000!). I highly recommend this product if you are looking for a meter to use at home that will measure the amount of electricity a particular device uses when it is plugged into an outlet. I've used it for a few weeks and it appears to be accurate for all the measurements it makes. It is of decent quality construction and I appreciated the inclusion of a short extension cord to make connections easier than needing to go straight into the outlet, or straight into the device (for odd locations or shapes, like a wall wart). Nice little freebie to make life easier and enough imo to put this above competing products. The buttons and functions all work and the display is easy to read. I'm confident in the quality because I have used it with high-power devices for long periods of time (longer than recommended once (by accident!)) There are a lot of competing products in this price range, so it was difficult for me to choose, but I'm glad I chose this. Upon receipt of the product, there was one little hiccup for me. I don't know a lot about electricity and there was one part of the instruction manual I found confusing. I moved on to other chores and hadn't thought much about it when I received a follow-up email from the Seller, Aaron, checking to see if everything was okay. I told him that I didn't understand one of the features and he quickly replied with an explanation of the feature. Being a little slow on this subject, I told him I didn't really understand, (still). Most sellers probably would have just offered a return or refund at this point, but Aaron really went out of his way in two more emails to help me understand and helped me learn how to get the most out of this product. So, in a market where there are a lot of choices and all of the products are of similar quality, features and price, I can recommend this one because of the great customer service. Let's face it, dealing with sellers of electrical devices on Amazon can often be frustrating due to language barriers and communication difficulty. That is not the case here and I received exceptional customer service and the product has worked exactly as advertised.

I bought four of the Poniie PN2000 because it has a critically important feature not found in similar products: It has non-volatile memory when totalizing kilowatt•hours. If you are going to be monitoring the total amount of energy consumed over a period of weeks, you want to be invulnerable to a two-second-long power failure (or longer) that would reset your reading to zero. This is a huge advantage for the PN2000. Unfortunately, all four of my PN2000s had receptacle contacts that were exceedingly weak; it was far too easy for slight tugging on the cords while handling equipment to partially pull the plug from the device. The receptacle contacts—even when brand new—have the retention of a 20-year-old plug in a cheap college apartment. This weakness in contact force suggests that the receptacle and a plug could overheat when carrying currents greater than the 1.5 amps I’m currently drawing but still under the 15-amp rating of the device. Also, of the four PN2000s I received, one, which was powering a 175-watt heater, was showing the correct amount of current and voltage, but strangely indicated zero watts even though I could feel that the heater being monitored was cooking away. Perhaps this was a temporary bug and all I needed to do was completely unplug the device… but then, I didn't want to tempt fate with a heating process that was critical to remediating some hazardous waste at my company.

Great power meter with lots of functions: Wattage, Current (Amperage), Voltage, Frequency, and others I'm not all sure of. I love seeing how much wattage I'm using in the moment and over time. It's able to keep record of that amount without power or needing batteries which I love. Comes with a 1ft 14 guage extension cable so you can use the meter anywhere you wouldn't normally be able to plug it in due to its size.

I mainly purchased this meter for the voltage and current (amps) readings. I rebuild vintage jukeboxes and there tube amplifiers. This is a great meter to hook up to an older variac to show how much voltage is being dialed in. It can be easily switched from voltage readings to amperage. A lot faster than hooking up two multimeters. The readings are very accurate. Great purchase. A handy meter to have.

seems to work great not sure on the accuracy

Gives you accurate readings of electrical consumption of any thing that runs on normal electrical current.

Thanks to this gadget, I now know how exactly much electricity (in kwh) my electric car uses each time its batteries are charged. Easy to use, clear display, different information display options available. I only wish it were weatherproof so I could use it outdoors without protecting it. But then it would prob be much more expensive. As it is I'm happy with it.
