Kill A Watt Electricity Usage Meter P4400

Kill-A-Watt Meter

It’s rare to find something as useful as a Kill-A-Watt meter at such a low price. Not only have I measured the energy use of every device in my home, I’ve also used it to keep track of the energy output of my photovoltaic system, and as a tool to help me plan for future upgrades.

Once you own one, you’ll be surprised at the number of ways you can put it to use. If you’re trying to squeeze every last watt out of a PV system, you’ll find yourself testing appliances under different conditions. You can find out how much energy you’ll save by moving your freezer from the garage to the basement, for example.

But the Kill-A-Watt meter’s uses extend beyond a PV system. With it, I learned that my old refrigerator was costing me over $200.00 per year to operate, and that I could replace it with a larger unit that would only cost me $50.00 per year in electricity. I replaced the refrigerator, and immediately saw a significant reduction in my electricity bill.

The Kill-A-Watt meter lives up to its reputation, and performs as advertised.
