Best Electricity Usage (Power Cost) 2020 Detailed Review

Best Electricity Usage (Power Cost) 2020 Detailed Review.

Best Electricity Usage (Power Cost): Any time you’re using electric devices with high power draw, you may want a way to keep tabs on your actual power use.

Usually, this is hard to quantify. For example, many consumer electronics use what’s called “phantom power”. Even when they’re turned off, they’re still running up your power bill. It can be hard to find the source of phantom power. 


Additionally, you’ve probably got a number of appliances in your home that operate on a cycle. Sure, you know that your clothes dryer is 500 watts, but what does that work out to yearly, when you’re only running it for a few hours a week? 

Whether you’re just looking to take a quick at-a-glance reading or estimate your monthly bill, an electricity usage meter is a solution. These handy little devices are manufactured for a wide variety of purposes, each of them with their own specific design. 

P3 International ‘Kill a Watt’ EZ Electricity Usage Monitor 

P3 International ‘Kill a Watt’ EZ Electricity Usage Monitor 

The P3 International ‘Kill a Watt’ is perhaps one of the best known on the market. The manufacturer was one of the first to publicize issues such as phantom power draw and provide a solution for consumers who were concerned about it.


As you can tell from the design, the P3 International ‘Kill a Watt’ Electricity Monitor hasn’t changed in many years. While it might not be the most modern-looking power meter, it’s one of the most well-known and reliable devices on the market.

The design is simple and functional. It’s about 5 inches tall, 2.5 inches wide, and sticks out from the wall a little more than in inch when plugged in. On the top, you’ve got a large LCD display that gives you real-time readings about your power use, with a number of easy to access controls below it.

The bottom is occupied mostly by the standard 120V outlet. Other than that, this meter is pretty simple in design. Let’s see how it performs. 


Just below the LCD display, you’ve got four buttons. Each of these buttons changes the information that is displayed on the screen. Kilowatt-hours (kWh), the measure of energy consumption over time, are always being recorded.

The other buttons are handy if you want to have real-time information about the quantity and quality of electricity that is being used. You can measure voltage, amperage, watts, and frequency. 

Belkin Conserve Insight Energy Use Monitor

Belkin Conserve Insight Energy Use Monitor 

Belkin is a company that’s well-known for its high-quality products sold at a generally affordable price. With their power meter, they’ve taken a classic idea and put a modern twist on it.


The Belkin Conserve Insight is one of the most attractive energy use monitors that we’ve seen. It’s got an attractive, modern face that wouldn’t appear out of place on any desk or table.

But the best design element of this unit is the remote display. Often, our plugs are tucked in behind shelves or other furniture. In this case, how are we supposed to get our readings? With the Belkin Conserve Insight, it’s simple.

The display is attached to a long cable that allows it to be placed out on a desk somewhere. This way, your readings are just a quick glance away.

The display is much more compact than other units, although it’s still clear to see your readings. On the bottom of the display, you’ve got three buttons, each of which toggles a different reading. 


There are three types of information provided. Of course, your power use in kWh is going to be the most useful. By tapping the power button, you are able to scroll through a few different options.

You can see your actual measured use to date, estimated monthly use, or estimated yearly use. This meter is pretty smart, so this estimation will get more accurate over time.

For example, when you first plug it in, the meter is going to assume that whatever you have connected to it is in use 24 hours a day. But after a few days, it will know how long you use it for each day. This allows it to estimate your average daily, monthly, and yearly use.

In many ways, this meter combines the best features from the other two meters. You’ve got all the base measurements that you want from a meter. It tracks power (watts), energy (kWh), voltage, current (Amps), and Power Factor (Watt estimation).
