Can this device display the dollar cost of energy consumption over a period, if given cost per kilowatt hour, or do I have to do the math myself?

Yes, it will. You can enter your cost per kWh (to the nearest cent) and it will tell you how much that device will cost you since you plugged it in, for an hour, day, month, or year.

There's another version that does the math for you, I think. With this cheaper version, you do the math yourself. Once you put the formula in a spreadsheet, though, you can just copy-n-paste for each device you measure. And this way you can customize the math for exactly your electric rates, instead of some national average.

These will give you a total use of kilowatts in real time and you just multiply it by your Cents per KW the utility charges you on your bill. Simple. If your P3 measures 29.7 kw over a month, in example you would multiply it times your cents per Kilowatt like this: 29.9 X .12 ( 12 cents is example cost) and get $3.55 of power used for that item or items ( up to 1600 watts safely) you have used.

dont forget neighbors that might be pluging into an outlet you have out side while your away all day or night

I believe that should be possible, Just put the wireless transmitters to the lines on the sub panel and it should display the watts used only from the subpanel.

Once the device is removed from the power source, the data is lost. Our customers plug an appliance in for 24-48 hours, get the total kWh during that time and determine what percentage of their monthly utility bill is going to that appliance.

Yes. It will measure and calculate cost of only the electricity passing through the sensors. For example it could measure only the power used by an air conditioning unit if it was mounted on the wires going only to the AC unit. Power used by the rest of the house would not be measured.

I had the same question and looked up the wattage which stated 56. So if it ran on that setting 24 hours that's 1.3 KW or approximately 1,344 watts per day. I'm paying on average 17 cents per kilowatt, that would be roughly 22 cents per day, $80.00 per year.

Yes - As you repeatedly press the Meter button, the display cycles between (first for the connected device) Watts, Volts, Amps, Kwh, Elapsed Time, (then "Saved" quantities) Watts, Amps, Kwh, Elapsed Time. I'm not sure how the "Saved" quantities are calculated, so I ignore them.

My answer is probably useless... But I replied so you weren't left hanging. I hooked up my computer to it and set the cost for kW/h to what I think my service charges. After one month it cost me more to just run my computer than my entire cilco bill was. I am betting that is just me who did it wrong. I haven't tried very hard with it. I don't want to steer you away if you are planning on using it seriously and you are good at what you do. I would say it was of by 400%, but could have been me. THE DISPLAY IS VERY DIM.

The high setting on the heater is 1,500 watts which is equal to [1.5 kilowatts] - (kilo = 1000).Your electric company rate charge is based on "kilowatt hours usage" - the number of kilowatts of electric you use in one hour. What do you pay per kilowatt hour (usually around 9 - 12 cents per kilowatt hour is typical) - it should be listed on your bill? Multiply that "per Kilowatt hour rate charge" times 1.5 kilowatts (heater on high). Example: 1.5 X .10 = 15 cents "per hour."

Yes. the watt button gives you instantaneous power usage.The KWH kilowatt hour button gives you power consumption over time.For example, keep your refrigerator on it for 24 hours tells you how muchpower it uses on a typical day. The meter doesn't have batteries. It uses a small amount of current to operate. a power loss would lose the measurement.

It will be based on what your city charges for rates per watt. The company K and H advised me that it would be pennies per day.

I never programmed the cost per KWh so I never worried about resetting when moving from device to device. I have had the unit for a couple months and first used it for a month on my 30 year old fridge. It used 100 KWh during that month. My tier 1 cost is $.13/KWh so I know it cost $13/mo to run. It is now on a freezer in my garage for a month. Its a lot newer and so far used a lot less that the fridge. Sorry I couldn't help you but I never bothered programming because of multiple tiers of electricity cost. Now I have gone solar so I am always in tier 1.

Hi Mr. Hogan,I installed a Kill-A-Watt from Radio Shack tonight. While using an internal Seagate 500GB hard drive the meter shows usage is 5 Watts and .07 amp draw. The figures are different from one electric provider to the next. As an example, my local electric company charges me 12 cents per kWh during peak season and 11 cents during off peak season. It's costing me $5.26 per/year running 24/7/365.It's been running flawlessly since December 25, 2012. Yes, over a year and I share family pictures to lots of family members. Very easy to use.I hope this helps.Thanks,Terry Mundy Hi Mr. Hogan,I installed a Kill-A-Watt from Radio Shack tonight.

You'll have to ask this question to an electrical engineer who could calculate this for you if you provide him with enough data such as power consumption and the gage of the wire that you are planning to use.

That's a very tough math problem, James! Since you're using 0.015 kWh per day, that's 1 kWh every 67 days. Depending on your power company, 1 kWh probably costs you about 15 cents, so you'd be saving about $1.00 per year...not too impressive. The main reason I bought this was not to save money, but to make it possible to install a security light without needing an outlet.

It uses about 500 watts per hour. Utility departments usually charge by 1000 watts per hour (kilowatts per hour.) so it would take about 2 hours for 1 kilowatt rates per kilowatt ranges from 7 cents to 12 cents depending on your total electrical usage. In my case LADWP charges 7 cents for the first 350kwh 8 cents for the next 700kwh and 12 cents for the next 1050 kwh. So to find out how much your bill will increase multiply how many hours per day it will be use x the number of days in your electric bill cycle usually is 60 days x .08 cents (which is average for most people unless you use a lot of electricity. But check your bill statement) and then divide it by 2 as it takes 2 hours for 1kilowatt

Unbelievable. That's my take on the price point established for this device. $2k to charge a USB device? 100w? That's about .8 (eight tenths) of one amp of current for any device needing 120vac (w/v=a). I can certainly understand the utility aspect of this item, but not the price being asked for such anemic output or novelty of sun tracking. And sorry, Matt, but "600" watts doesn't even come close to a 'typical' refrigerator. Mine demands 9.7amps - that's (v x a =w) so that's 120 x 9.7 = 1,164 watts. The price point is ludicrous for what is being offered.
