Upgraded Watt Power Meter Plug Home Electrical Usage Monitor Consumption, Energy Voltage Amps Kill Tester with Backlight, Overload Protection, 7 Modes Display

For those looking for a Kill-a-Watt type of device, this is a very good substitute. It's backlit, so it's highly readable when it's dark, fits into a wall or power strip socket snugly, is well-built, and has additional features, like tracking price over time. Overall, very easy to use and a great product to track power usage!

Got a pair of these to use for monitoring/measuring wattage consumption for various appliances and devices in our house, prior to having a generator switch installed in our house.In order to determine the branches to power through the generator switch box and how much each branch will consume for the total wattage and capacity of our generator, these two plug in monitors are proving to be worth their weight in gold!The display is crisp, the text sharp and easy to read and the backlight display, when needed, is a huge plus. The assorted options available for settings and view of volts, amps, watts, watt-hours, electrical cost factor, etc, are also excellent.Delighted with these and I might be ordering one more to monitor another major appliance we'd be using during a power-outage and generator use.My only regret is not being able to monitor 240 volt appliances like our oven/range and dryer, but, I'm searching for one specifically for this and if they're available, I'll consider getting one of those as well.As for these wattage monitors, delighted with their performance and the reasonable cost per unit. 5 Stars all around!

Nice, inexpensive device. Very useful. 4-5 stars except for these negatives:1. Some controls and settings are virtually impossible to access unless you have the instructions. Not intuitive at all.2. If you want to know how much power your device uses in an hour, day, week, month, etc you must write down when you plug it in and when you unplug it. The meter will not give you that information. It only tells you how many minutes, hours, days, etc. your device is running. e.g. If your fridge, AC, or heater cycles on and off, it will tell you how many minutes, hours, days, it's been running, not how many days the appliance has been plugged in. You might have it plugged in for a week and the meter might say "3 days" because that's how long your appliance ran since you plugged it in.I've been using two of these every day for a couple months. I love the large bright blue display. You can have the screen on all the time or turn it off. By default the screen turns off after 10 minutes. Good purchase if you want to measure electricity usage.

I use this power watt meter to track power usage for my work computer. It tells me not only how many watts it is using right now but how many kilowatt hours it uses over time and how much the electricity costs. It also keeps track of the minimum and maximum watts used. The backlight display is really nice. It comes on when you press a button and turns off after a certain amount of time. I am very happy with the functionality and ease of use. Time will tell how long it lasts.

Great product with a multi function display.Pros:- Very easy to read, large backlit display- Tracks power usage- Plug and play operation.Cons:- Bulky- not WiFi or BT capable.Summary: Ive owned this for just over a year. Originally purchased because my aquarium heaters built in light stopped working; with KillaWatt meter I could see an immediate power draw when the heater turned on; allowing me to set the water temp easier and more precise. Since then, I've used KillaWatt for other household and home shop items, to check and record power draw over time, to compare efficiency and power consumption with stated ratings.

This item works great, plug and play. Wanted to know how many kilowatts I use in my EV, and it records them perfectly. Even has a cost calculator if you know how much you pay per KWH.

These work great and I got two because the two-pack was not much more cost than one. The display is very easy to read and if you know anything about basic electricity these are very easy to use and understand. First thing I was curious about was how many amps & watts the electric heaters and window AC unit were using. I discovered that my electric heaters that are a few years old are not using 1500 watts, but less, and the AC window unit was more efficient that the specifications say it is. Now I know why one 1500 watt heater is giving off less heat than another 1500 watt heater. Most folks should have one of these in whatever type housing they live in. If some electrical device you are using is drawing less or more than it is supposed to you should check it carefully or have some experienced electrician check it out. I disposed of the 1500 watt (rated) heater than was using just 1000 watts and bought a new one that really does use 1500 watts. Big improvement in heating a bedroom with the new heater.

This works like a charm, the included power cable is really a nice add on that makes the application much more simple. Huge value for the money. Would buy again.
