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

Very handy gadget. Works every time--plug in get watts draw. Quite simple. Would buy again.

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.

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).

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.

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.

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.

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 don't have enough electrical outlets in my home office, so I've got multiple-outlet surge protectors plugged into almost every one. I started to become concerned that I might be getting close to overload on some of them and on the room's circuit as well and wanted a way to check. The Poniie PN2000 was the perfect answer. Plugging each surge protector, one by one, into the PN2000 and then operating all the devices connected to it gave me a clear idea on the current it was drawing. Printing a document while using the HEPA air filter and Humidifer on Max and the lamp turned on--you get the idea. I was able to determine that I was using only a few amps on each wall outlet and that I was well below the room's 15-amp circuit limit when all were in use. The PN2000 comes with a 1-foot heavy-duty extension cord that you can use to get the Poniie away from the outlet you're testing. Some of my outlets were pretty inaccessible and this was a great help. But even with that aid and the PN2000's illuminated LCD screen, if the wall outlet was behind a piece of furniture, I still had to bend myself into some uncomfortable positions in order to see the display. If I could make just one suggestion, it would be to provide a slightly longer cord, perhaps 2 feet, and with a flat plug. The printed user manual is clear, complete and easy to understand. I would like to have seen a certification from UL or a similar organization but none was present. The PN2000 is made in China.

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.
