Answer: 
Yes; the true rms (root mean square) amperage is displayed by pressing the second button (labeled Amp). While "rms" amperage is calculated, it's easiest to just view it as an average value of amperage measured over time.
The monitor is rated at 15 amps maximum and 1,800 watts.

Answer: 
The tool will NOT directly display amperage however using the formula P= E x I where wattage equals voltage multiplied by amperage you can easily calculate amperage. This is very basic high school physics

Answer: 
Except for KWH and Elapsed Time, all readings are real time or what is happening at the moment. If it is plugged in to monitor something with a compressor (refrigerator, freezer, window AC unit, ...) and the compressor turns on, the unit will see the surge of the turn-on event, and only retains the values for purposes of calculating the total KWH over time, but not for individual parameter display once Read More

I don't believe so. I don't have the manual anymore. Its main function is kWh over time. I got it to measure usage from things that run intermittently like refrigerators and air conditioners. It failed though.

The Kill-A-Watt meter gives real time readings. You would only see a spike reading if you just happened to see the spike as it happened. It does not record low or high data to be retrieved later.

Probably not - the monitor is intended for use on a single, 120 V, plug-in device at a time. The monitor is rated at 15 Amps and 1,800 Watts maximum.
Typically, refrigerators & window air conditions: 1) require 15 or 20 Amp circuits, 2) are not powered by the same circuit, and 3) have warnings against the use of extension cords. Without knowing the details, to attempt a test as you ask about creates a Read More

Rated 4.5 out of 5 by 68 reviewers.
Rated 5.0 out of 5.0 by A small electrical tool every homeowner should have. This a small but great electrical tool every homeowner should have. You can really find out how much power each of your appliance or tool is using. It is good to test and make a note of the power each item is using. It will be useful in the event of power failure, and you want run the tools or appliances in your home with a generator. August 7, 2016
Rated 4.0 out of 5.0 by energy costs What a great way to research energy cost and drain your typical household appliances use. I tested mine on lights and power tools and really think this could be something to try throughout the house to see where my energy bill is going to and what simple things I could do to save electricity. Easy design and straight-forward operation. fairly quick reading during operation. April 28, 2016
Rated 5.0 out of 5.0 by Such a neat idea Honestly, I never knew how curious I could become about how my appliances use electricity until I gave this a try... One of the things I had been wondering around my home was with recent additions of two different aquariums, and noticing that each had around 4 or 5 things plugged into it, I was really concerned with the level of electricity they would use. This tool gives you several different ways to track and monitor usage and it is dead simple to use!! April 5, 2016
Rated 5.0 out of 5.0 by Fun and educational If you've ever wondered how much electricity an electrical appliance/tool/computer/light was actually using, this thing is the bomb. Just plug the appliance into the unit and it'll tell you the power consumption. I'm not sure you'd want to plug a high-draw tool like a skill-saw into it as that may be more than it's designed to handle, but go ahead and post your results. April 14, 2016
Rated 4.0 out of 5.0 by Helpful Tool to Determine Usage I was so excited to try this monitor on my refrigerator to see electricity usage. The monitor displays many different items, volt, amp, watt, Hz & KWH. This is a good tool to use to see what items in our home use the most KWH. The only downside is this cannot be used with an electrical extension cord. What refrigerator plugs into a socket you can see? You have to view the readings while the monitor is plugged in. That makes it almost impossible to use for a refrigerator without pulling out the refrigerator and taking readings while the monitor is plugged in. There is no memory, so when unplugged, you lose the readings. This is a good idea, but really only useful on items where you can get your face to the plug to read the output. February 3, 2016
Rated 5.0 out of 5.0 by Must have at home Electricity can become really expensive. I have a hunch what appliance eat up the electricity but there is no proof. This small unit can now tell you what the usage is. This will certainly tell the fact about electrical use. In my opinion, every one should have this. Just read all the instruction before you use it. As a real man, i skimmed the instruction and it cost me much time. Its simple operation will give you the fact of which appliance is the actual energy hog. March 4, 2016
Rated 5.0 out of 5.0 by Excellent Item for Saving Money This item does not require any tools or batteries. Just plug it in then plug and electric item into it. It will keep track of how long it has been plugged in and also record the electricity used. To reset it simply unplug it and plug it back in. We have used it on two refrigerators, a heated waterbed and all the other electronic devices in our home. Based on the changes we have made this item will pay for itself in about five weeks. This item also alerted us to a malfunction in an item that could potentially have caused a fire. July 6, 2013
Rated 5.0 out of 5.0 by Informative The display is on the front of the unit, is approximately 1" X 2" and easy to read. It would be a lot better if it had a back light. Also it would have been nice if the display was on the top. Most of the appliances I wanted to use this on sat in front of the outlet and couldn't easily be moved to read the display. If the display had been on top I could have read it. It measures and displays volts, amps, watts, volt/amps, line frequency, power factor, kilowatt hours and elapsed time. The kilowatt hours feature can be used to determine what each of your appliances cost to operate. December 28, 2015
