Customer Product Reviews

Rated 4.6 out of 5★ by 40reviewers.
Rated 5 out of 5★ by It helps to know What can you do with it? Figure out that your old chest freezer is costing you a fortune and the new energy efficient one is performing as advertised. That your LCD HD TV and direct Tv DVR runs even when off and that by making a few changes to your TV, like turning down the brightness level, backlight, and just playing with different configurations I cut almost 100 watts . That alone will pay for the Kill-A-Watt meter over time. 09/07/2011
Rated 4 out of 5★ by Kill-A-Watt does what it claims without a fuzz Received the Kill-A-Watt a few days ago. Simply plug into the wall outlet and plug the appliance into it - voila'; easy to use with simple instructions. Settings for voltage, amps, hertz, and Kilowatts per hour with a duration clock. I've set it to measure KWh and continue to monitor the daily usage of the appliance. This will help me determine if the appliance is a power hog or not. Recommended for those who want to understand their household's electrical usage and those who want to reduce their power consumption. 10/25/2012
Rated 5 out of 5★ by This thing works great, I found out my dvr pulls 35 watts with it turned off.I wanted to buy an inverter, and wanted to make sure it was big enough. 09/10/2012
Rated 5 out of 5★ by Excellent instrument for the money. The number of measurements it can do for the price is amazing. 08/30/2012
Rated 4 out of 5★ by Does what it claims & helped me save over $100/yr I found leaks electrical "leaks" all over the house. My FIOS HD box uses ~19 watts even when it's off! This isn't a DVR, just the box you need for HD. It only takes shutting down a few leaks like that to save the price of this Kill-a-Watt. 01/15/2013
Rated 5 out of 5★ by Bought this instrument to determine what kind of electrical load was being put on individual electrical circuits. I live in an old, old house that has some 14 ga. wiring along with 12 ga. wiring so it is essential to know how much of an electrical load overall is being put on individual circuits and how much power individual appliances are drawing.I am using it on mostly portable appliances right now. I was surprised to find on two different space heaters that are rated at 1500 watts each, one draws 1350 watts and the other draws 1630 watts. I certainly would not recommend either of these two heaters on 14 ga. wiring.I also have a wood insert stove with 4 fans. Again, I was surprised. This appliance draws only 1 watt of power. I was sure it drew more.Most people are not concerned with the electrical power portable appliances (or permenant ones) draw. That is why they will try operate a microwave and a toaster at the same time on the same circuit. This instrument can tell you quick how much load you are putting on a circuit.This instrument has 5 different settings: volts, watts, amperes, amp hours, and kilowat hours. No better educated than I am in this area, I can moniter my appliances and understand what is a better setting and placing for them and how to keep from overloading a circuit. 02/02/2013
Rated 5 out of 5★ by Great tool for learning about energy I've used these for years, both to learn what an appliance actually uses in electrical usage, and to teach people of all ages about electricity and power usage. The label on the appliance is often just an estimate; this is the simplest and least expensive tool for assessing its actual usage.They used to be $40 each and hard to find, to it's great to see them readily available and selling in volume! 09/06/2013
Rated 5 out of 5★ by They work great I'm using them in my solar system and they are giving me info on my system. 09/08/2013
