Questions & Answers

Will this display the voltage available at an outlet?
ByApr 8, 2019
5 Answers | 
Answer This Question

Yes, simply plug it in.

By|Apr 10, 2019

    Yes it displays the voltage, amperage, wattage, VA. if you enter your cost /kw it will tell you the cost.

    By|Apr 9, 2019

      It does, yes!

      By|Apr 12, 2019

        Yes. This meter plugs into an outlet with its male prongs on its back side. The left MENU button can choose which reading you want on the meter. One menu option is Voltage. In that choice, it will measure the voltage of the outlet into which you plug it. Checking this voltage FIRST will prevent your accidentally exceeding the reasonable voltage for the device for which you are wanting to determine its power consumption. Many rural electrical supplies send higher than 120 VAC as a safeguard against brownouts, with the resident paying via early burned out light bulbs. When you plug another device (lamp, TV, small motor), then the voltage to the device will be the same as voltage supplied by the outlet. Menu allows you to enter a utility company rate for KWHR (typically about $0.10/KWHR). Menu will then provide (power)X( time)X(rate) to give you cost of operation of the device over that time period. Essentially, you "sub-meter" each device.

          Of course, and so much more, current, watts, watt hours, costs, etc. Displaying the voltage is a simple task for this meter.

              Can this meter measure the surge wattage of a device?

              6 Answers | 
              Answer This Question

              Maybe if you stand and watch constantly.

              By|Nov 25, 2018

                No, only measures kilo watts. You should use a power surge protector with it, I feel without one the meter can be damaged. I hope this can help.

                By|May 6, 2023

                  No, this meter measures voltage or wattage used.

                  By|May 6, 2023

                    No.

                    By|May 6, 2023

                      In response to the first answer, you make it sound like that is ALL it can measure, which is incorrect. According to the manual, it can display meter readings such as volts, current, watts, frequency, power factor, and VA. So yes, it can measure instantaneous amounts and not just cumulative. My question relates to how FAST the meter responds to changes, like surge wattage. If anyone has this and can try it, please let me know.

                      By|May 6, 2023

                        Nope. Continuous wattage only. Some other meters of this type offer a max capture feature, but how accurate they are would depend on their sampling rate, as inrush events tend to be quite brief.

                          Yes, as long as you plugged it into this meter and of course that your camper doesn’t draw over 15A. (Pay attention to the plug size/type, this is not a 20A, 30A or 50A device!!)

                          By|May 5, 2023

                            Only if the plug matches. Its a 3 prong 110.

                            By|Nov 25, 2018

                              Yes. You will need to plug the adapter into your home outlet then plug the trailer into this. That's what I used it for. It was costing me about $100 a month (somebody was living in the 31 ft. trailer at the time).

                                  so long as it has a normal 3 prong plug and does not pull more than 15 amps, yes.

                                    Less than a minute on items that are constant on and don't fluctuate, like a fan or tv left on 24 hours per day. A heater would kick on and off, so it wouldn't be accurate in less than a minute.

                                    By|Nov 25, 2018

                                      I would certainly leave it plugged in for at least 24 hours. As in their instructions, the longer you leave it plugged in, the more accurate. I will paste a few lines of their instruction manual below. You will need to personally look at variables as to what is plugged into the meter, and is it used consistently the same amount of time each day. If it is, I'd go with a 24 hour period to estimate the monthly usage. If you can leave it plugged in for a month into your meter, there will be no estimations, but rather the exact facts. Their information ... 4. Pressing the UP and DOWN key will cycle through the cost projection periods. “Hour”, “Day”, “Week”, “Month”, and “Year” will display on the LCD to indicate the selected period. The numeric display will indicate the projected cost to run the attached appliance for the selected period. For example if the display indicates $2.34 and “Month”, the unit is projecting that the attached appliance will consume $2.34 worth of electricity at the programmed rate in one month. 5. These projections are based on real time and historical measurements of actual consumption of the attached appliance. The longer the appliance remains attached to the unit, the more accurate the projection will be. This is especially true for appliances that cycle on and off. Examples include refrigerators, televisions, etc. Measurements conducted over long periods will accurately reflect true usage of the appliance. For example if a television is used 4 hours a day, it is important to measure the 20 hours a day the appliance is not in use to get a true projection of the cost. 6. For an appliance that cycles on and off, the projections cannot be accurate until the unit has measured some full on and off cycles. Otherwise the projection will be skewed. For example, if a connected television is powered on and you reset the Kill A Watt™ EZ, the unit will begin measuring the power consumption of a powered television. The only data available to the unit is power consumption when the television is turned on. Initial projections of cost will be high as the unit has not had the opportunity to measure power consumption during the off cycle. If you observe the cost projection while the television is turned off, you will see it decline over time. After the unit has been able to measure several typical use cycles, the cost projections will settle to an accurate projection based on real usage. 7. For a device that is never turned off (e.g. a computer server) the cost projections will take less time to settle. You can observe accurate cost projections within minutes. It is still best to let the unit measure power consumption over an extended period. There can be power consumption variations even in devices that are never turned off.

                                          it will calculate it immediately based on the current usage, it will get more accurate the longer its in place if the device cycles power consumption, for example a light that is on 24/7 will give you an immediate accurate result, but for a computer that is on 24/7 but used a few hours a day, it you should give it a week or so to get the most accurate info based on your usage.

                                          By|May 5, 2023

                                          How long depends on how accurate you want the reading when you are dealing with things like furnaces that shut off/turn on. If an item runs full time, without change, 10 minutes will get the answer calculated for a monthly basis. Pushing a button gets it figured for daily, weekly, monthly.

                                            You could use a power strip for multiple devices. Better to know the usage of each device though. Also it's possible to overload the breaker and or power strip.

                                              Yes you can but you are going to get the power that everything plugged into the surge strip is using as compared to individual devices.

                                              By|May 5, 2023

                                                In theory yes. However, I will only recommend using one item at a time. Use it for 24 hours, and then try the next device. Keep a log of what each item uses in a day and add them together when you've collected data for each item. With any electrical item, I never push it even close to the limits of what it's designed for. When in doubt, always choose safety over anything.

                                                    I bought this product about 1 year ago to see what my electrical usage was for my 50 inch plasma TV. Needless to say, plasma TV's use a lot of electricity verses the new LED TV's. Therefore I was able to convince my wife into getting a new 60 inch TV for the living room. So the Kill A Watt EZ Meter paid for itself in the electricity I saved with the new TV. I'm happy, and my wife is happy that I'm not complaining about the electric usage because I've used it on other electrical appliances around the house. This product is very useful if used correctly. The display is a little small, but what do you want for a product that is under $30.

                                                      Easy to use. Just plug in the appliance into it and see how much that appliance is costing you. Using this I was able to determine one portable heater was costing us twice as much as the other, even though the heater was advertised as being cheaper to run with the same BTUs. I took the most cost expensive heater back and replaced it with the other kind. What I like most is once you set the cost rate per KWH from your bill you don't have to keep resetting it everytime you unplug the device. It shows you how much your appliance cost hourly, daily, weekly, and monthly. If you want to save on your electric bill, this is well worth buying. It has paid for itself in one month of electricity.

                                                        Very handy for your budget and generator
                                                        I enjoy using this device around the house since I have received it. The manual is easy to follow and I quickly set my rate to 11 cents per kWh, which is what I pay. Once the device is plugged in, you get a reading quickly. It averages out as the device (like a fridge) runs then stops. You can easily scroll through the hourly, daily, monthly and yearly costs. If I charged my phone continuously for a year, it would cost $6.57 as seen in the photo. Other readings include Hz, watts and amps. All are important if you use a generator. I have a 2000 watt generator and can tell what my appliances, such as my fridge, draw so I know what I can plug in. Hz is important as well for sensitive electronics such as phones and laptops. My outlets and inverter generator read around 60 hz, where it should be. I plan to get a lot of use out of this device and recommend it if you are curious about cost, especially and extra fridge or TV. One downside is that the device is a little big so it won't fit well on a power strip.

                                                        Great way to kill those energy vampires in your home!
                                                        The kill-a-watt Es power monitor is super easy to use and understand. It gives you real time data on the power consumption of whatever device you plug into it. This unit had helped me identify several electronic devices and appliances that I thought were in a low-power or off mode, but we're wasting a ton of electricity! This u it paid for itself in the first month! Great addition to my toolbox!

                                                        Useful tool, I'm happy with it.
                                                        I read the other reviews. And, it does give an instantaneous reading of volts, amps, watts, frequency (Hz), volt-amps, and power factor. It's under 'measurement display' in the operating manual. It's only made for 120v appliances, hence the small plug on the front. It cannot check anything running off of a 240v circuit, like dryers and hot water heaters. Common sense tells you to dry more than one t-shirt at a time, and clean lint out of the vent to maximize efficiency. With water heaters, shorten your showers and use a timer if you are gone all day. It has a maximum power rating of 15 amps, so don't try to use it for big drills or large vacuums. That type of stuff you buy because you want powerful tools for the job, not to save power. One item I tried it on was my dehumidifier. I found that it used almost as much power (watts) with the fan on high, as it did on low. Most of the power is used by the compressor, not the blower fan. So, with this meter, I now know it is better for me to use it on high and turn it off, than to let it run all of the time on low. After running the device for a day or two, it calculated how much per day it cost to run it. It also showed how much for a week, month and year. But unless you are going to run something the same way every day, the long term calculations aren't necessary, but still available. It's a nice tool, priced reasonably. It will show you how much power your items use when they are not being used. When my computer was off, my power strip was using 25 watts still, because the printer, scanner and hard drives were sitting idle. Just like leaving a ceiling fan or light on in an empty room, it all adds up. This will show you how much. If you use your new knowledge this provides, and turn things off more when you leave, it will pay for itself and a lot more.

                                                        Works Great!
                                                        It’s Easy to read, tells you all and more than you need to know. If you plug it somewhere you can’t read it you can unplug it when you done and plug it in somewhere else and it will tell you how much it used and how much it cost. This is a great feature.

                                                          Simple directions, very easy to use. I used it to see how much energy my refrigerator uses and what it costs to run ($.01/hour) and now have it monitoring how much my TV/cable box uses/costs. I'd recommend it to anyone who want to know more about how much energy their plug-in appliances use.

                                                          Product is good overall. Screen is a little hard to read. letters could be bigger.

                                                          well worth every penny i have several of them
                                                          This meter is wonderful. I previously had an earlier model from the same company, and the kWh tracking feature would reset with any power loss. This one has a battery. It also has a VA meter in addition to the watts meter. With my older model I was struggling to understand why a 20A breaker kept tripping with only 1780 watts consumption when it should be fine until 2400 watts, but I learned that watts arent the whole story. Watts are the power used and what the power company bills you for. Volt-Amps is a term used basically for what i like to think of as “maximum instantaneous watts used” so an older appliance or cheap one might have a power factor of 0.7 meaning that if it really only uses 70 watts of power, the circuit needs to be designed (breaker, wire gauge, switches, receptacles, etc. ) assuming 100 VA because even though its averaging 70 watts, it reaches 100 instantaneous watts at a certain point 60 times per second during the AC cycle. Sorry, huge tangent. Anyways this thing pays for itself quickly being able to measure actual consumption on your appliances and devices and knowing when youre wasting money
