PN1500 Portable Micro Electricity Usage Monitor Electrical Power Consumption Watt Meter (110V, 1500W)

As a satisfied user of the Poniie PN1500 Usage Monitor for the past 2 years, I highly recommend this product for those looking to manage their electricity usage effectively. The monitor is light-weight and portable which allows for easy movement around the home, and its simple installation process makes it easy to use right away.One of the most impressive features of the Poniie PN1500 is its real-time monitoring capabilities. Its large LCD screen displays current electricity usage data, allowing for accurate tracking of energy usage and cost. The memory function also provides a great way to track usage over time and adjust usage habits accordingly.The monitor's overload protection shuts the unit off during energy surges. The cost calculation function is also incredibly useful, giving a true understanding of the cost of electricity usage and helping make informed decisions about energy consumption.While there are a few areas of improvement I'd suggest, such as the inclusion of a mobile app or compatibility with smart home systems, overall I am very satisfied with the Poniie PN1500. For those looking for a reliable and user-friendly way to manage electricity usage and reduce energy bills, I highly recommend giving the Poniie PN1500 a try.

I've bout 3 of these over the past few years, and had my dad buy one too. All of them are fantistic and reliable. Small too. These are super usefull for diagnosing issues, monitoring power, or if your just plain curious how much that one thing draws. Really like the cumulative KWh that does not get lost even in power outages. I started using these for switched circuits on a solar system and they work great to log long term usage.

Love these. Good functionality and price. Small footprint. Keeps track of KWh, time of use, until you reset manually. I can see W, VA, PF, A, VAC, and Frequency (one at a time). Screen lit so can see in the dark. Bought a second one so I can have one available for other uses.

This review is for the Poniie PN1500 Electricity Usage Monitor. First off a couple of nits regarding Amazon's processing of the order. The PN1500 comes in a manufacturer's box that's 2x2x4”. Amazon shipped this one item in a 6x5.5x9” box; could have held about 20 of the PN1500's. I really don't need more cardboard that I can't find places willing to recycle. Next, because of a delay, Amazon “upped” my order to UPS vs USPS shipping. That's fine for summer weather; but for rural folks during the winter, the UPS drivers are dropping off more and more packages at driveway entrances rather than risk going down a snow covered drive that they might get stuck in. I've noticed my local UPS delivery trucks no longer have true mud/snow tires on their rear wheels for the last few winters. However, a recent Fedex delivery showed up in small van with good mud/snow tires on it.Overall I like the Poniie PN1500. It arrived in excellent condition and it's been working as advertised for a number of days now; but there are a few things to be aware of:First, it is a very small unit; about 1/3-1/4 the size of the Kill-a-Watt product. With the outlet just below the control buttons a large heavy duty straight appliance plug (vs typical two wire lamp plug or a right angle appliance one) may interfere somewhat with your access to the buttons. In addition, I've found I need to use the tip of my finger nail to press buttons because the buttons are fairly close together. This situation is compounded by the very small, 1/16” tall, characters used to indicate what mode the display is showing. The number size is absolutely great; but definitely not the screen mode indicators. Several times now I was briefly confused when I thought I was reading the KWH/Hour value and it was actually the Amp display. I would also like if the unit provided an average power consumption (energy used divided by on time rather than only elapsed time) of the device being tested in addition to the existing measurements.Second, like most of these plug in monitors, the display faces straight forward which might be fine for the 30” height of washer/dryer, kitchen countertop, or refrigerator outlets; but it is really, really inconvenient to operate/view for the typical 12” height of common USA home wall outlets. I've always thought these monitors should use a “remote head” for the display/controls with a simple 3-6 ft phone/ethernet cable connecting the plug-in part to the head unit. True, there are bluetooth or even wifi versions out there; but really folks – for something you need to check just once in a while after the initial fascination has passed. And double extension cords to move the unit out so it can be used is annoying as well.Third, having the backlight on constantly as default seems a bit odd. Nothing like having yet another “night light” glowing from behind a refrigerator or washer/dryer. I reset it to the 10 sec auto-off feature within first few minutes of using the PN1500. However, keep in mind that by pressing the Watt/VA, Hz/PF, or KWH/Hour button to turn on the backlight, you will also be selecting the alternate choice on these selections. For example, if the backlight is off and you last had the unit displaying Watts; when you press the Watt/VA button to turn on the backlight to read Watt again, you will actually have switched the display to the VA reading. Get used to double pressing button operation or using a flashlight in dark areas so you don't have to touch a button. This isn't a problem with the Volt or Amp buttons since they only have one normal function. It'd be nice if a quick press/tap of any button just turned the backlight on and didn't change anything else.Fourth, beware the wattage/amperage ratings on the unit. Oddly, the wattage rating is based on 110Vac. Most American households tend to have 115-120Vac these days. The 1540W maximum rating at 110Vac yields the specified 14 Amp maximum current; but if you have 120Vac line voltage the maximum current should limited to no more than 12.8 Amps. So, check your line voltage first after inserting the PN1500 in the outlet and before plugging your appliance into the PN1500. Then calculate your situation so you won't be exceeding the wattage limits of the PN1500.Fifth, there are obvious errors in the manual. Section 2 for “Voltage” shows a display of 220.0V even though the text says the range is 100.0-140.0V and the spec section states the unit can display 110-140V. Section 3 for “Current” states range is 0.00-15.00A; but specs state maximum rated is 14A. The list continues...Finally, the watts and PF calculation is just a circular explanation citing formulas; VA=Vrms*Arms, Watt = VA*PF and PF=Watts/VA. There's no proper explanation of how PF or Watts are arrived at. Obviously the device measures VA directly just like a regular multimeter would. Watt measurements have often been done by custom IC's that measured a heating effect (the heating technique avoids PF and non-sine wave influence) and then PF is calculated by the formula above. Other techniques require timing the difference between the zero crossing (or peaks) of voltage and current waveforms; but results can be erratic with non-sine waveforms (which the PN1500 manual states no “inferior quality power supply”; i.e. modified sine wave inverters). While the method of obtaining PF or Watts is unknown in the PN1500; I haven't observed any significant errors with the Watts or VA measurements and the PF values are on par with heaters and appliances I've tested in the past.

We bought this to try to monitor our power consumption, we could not figure out why our electric bill was so high. Turns out its mostly just he way we are living. But we were able to figure out we were burning thorugh enough electricity on an ancient freezer that we really needed to buy a new one. The display in this thing is big enough and bright enough to read in the basement. Good way to check power consumption. And super simple to use.

Works perfect with my solar grid Tie inverter. Great value for the money and of good quality. Display is easy to read.

This is an easy way to identify how much power is being wasted by leaving your devices and appliances on. I was able to find several devices wasting hundreds of watts and increasing my electric bill. By identifying things that dont need to run 24/7 I was able to shave almost 100.00 off my monthly bill. I also found that my little mini fridge on the back patio was using 3 to 4 times the power that my main fridge is using, possibly a bad compressor ( which was making some noise) may have been the culprit. Leaving printers on standby eat about 12 -20 watts, a 55" tv uses about 115 watts while on and about 3 watts when off, turn off the tv's wifi and save another watt ( while tv is off).a desktop p.c. uses 185 watts+ while in use, setting the power settings to sleep mode when not in use and it only consumes a bout 3-6 watts while in sleep mode.Anyway, it's a great little device that can help you find out where you are wasting energy and money, mine has already paid for itself several times over!
