SURAIELEC Watt Meter, Plug-in Socket Power Meter, Auto Cost Calculator, Backlit Large Display, Overload Protection, Kilowatt Wattage Voltage AMP Tester, Electricity Usage Electrical Energy Monitor

Essential Tool for Energy Monitoring!
I purchased the SURAIELEC Watt Meter as an aid to track the energy usage of my Level 1 EV charger, but it has proven to be invaluable for monitoring much more around my house, including my second refrigerator. This device is a must-have for anyone looking to keep an eye on their electricity consumption!From the get-go, I was impressed with the meter’s ease of use. The plug-in socket design meant I could get it up and running in seconds. Its backlit large display is a standout feature, offering clear visibility of the wattage, voltage, and ampere readings without squinting or needing to turn on extra lights.The auto cost calculator function is a game-changer. It not only measures the power consumption but also helps me understand the cost associated with running my appliances. This feature has been eye-opening, especially with my EV charger, as it allows me to optimize my charging times based on peak and off-peak hours.Using it with my second refrigerator has also given me insights into how much energy an older appliance consumes compared to newer, more energy-efficient models. This has helped me make informed decisions about potential upgrades and energy use management in my home.The overload protection feature gives me peace of mind, knowing that the device will cut off power if the load exceeds its capacity, preventing any potential damage to my appliances and the watt meter itself.The SURAIELEC Watt Meter is a robust, reliable, and user-friendly device that has made energy monitoring a breeze. Whether it’s for an EV charger or any other appliance, this meter provides accurate readings and useful insights into electricity usage. It’s an excellent investment for anyone serious about managing their energy consumption and reducing their environmental footprint.

Mostly good points, a couple not so good.
Overall I like the device. When plugged in, the display lights with any button press and remains lit for a while. I like that it shows the maximum watt draw. I wanted to know exactly that so that I could properly size an inverter to run a fridge and freezer on batteries during power outages. Each display has the cumulative time at the top. The “manual” states that this is the amount of time that the meter is connected to the power source. That is not correct, at least not on mine. It rather shows the amount of time that power is being drawn. So if this is connected to a cooler that runs intermittently, it displays the amount of time that the cooler is drawing power, not the amount of time that the meter is plugged into the outlet. So, you can’t know from the displays what the overall average power use is. You can only calculate the average power consumption while the cooler is actually running, which only occurs when the compressor is on. To know the average, I have to use a different KAW meter that keeps track of total watts consumed and total time the METER is plugged in. Other than that, it works well, but it’s not quite as useful as it could be. So, it’s a little bit of a letdown. But it does show the maximum power draw that occurred while in use, which my other meter doesn’t show. The time also shows the total amount of time that power is being draw, which my other meter also doesn’t show. It would be nice if it showed both how long the meter was plugged in AND how long a powered device was actually drawing power. Then it would be just about perfect.Setting the cost is slightly tricky. In the display with only the time and cost showing (no middle field), press the “cost” button for a few seconds. You are now incost entry mode, but you must press the “function” button so that the first digit starts blinking, and then the “up” or “down” key to change the value of that digit. Then press the “function” key again for the next digit and repeat for further digits. When set, press the “cost” button to exit the cost entry mode. You are now set. It seems that the first two digits should be for whole cents and the digits to the right of the decimal for fractional cents, so it is not a dollars and cents display. If your electricity rate is 33.14 cents per kWh (like if you live in California where they have cheap renewable power), the display, once set, will read 33.14, and if your electricity costs 6.04 cents per kWh (like where I live) then the display in setup mode will read 06.04. The actual total cost of electricity consumed will be in the mode 1 screen where time, total watts and cost are displayed.

2 year (sorta) review.
Sure it sat unused for most of the two years but it kinda counts.Pros:Good PriceAppears to be accurateGood featuresGood functionalityHasn’t started a house fireConsA few more decimal points in kWh would be nice. 99% of applications and users will never need/want to go beyond a thousandth of a kWh (aka a watt) but it would be nice regardless.Exact wattage range needs to be more clear. To me saying its wattage range is 0.0-3680w means that it can track a .5w nightlight’s power draw. It cannot. Most users will not need that but if you do or you want to know consider a different meter.

Very happy with the delivery.

I recommend this Suraielec Wattmeter. Initially this Wattmeter worked fine, but, about 5 to 6 months of no-usage, the Wattmeter’s display no longer worked. I contacted Suraielec Customer Support and the next day they contacted me to investigate the issue, and which proceed to the Wattmeter’s replacement.I would like to emphasize the rapid answer and the courtesy of the Surailec’s customer support people.Je recommande ce produit de Suraielec Wattmètre. Au départ ce Wattmètre à très bien opéré. Environ 5 à 6 mois d’inopérations, le Wattmètre, sont affichage n’opérait plus. J’ai contacter le Support Client de Suraielec et, le lendemain il me contactait pour explorer le problème qui finalement se conclut par le remplacement du Wattmetre. Je tiens à souligner la rapidité et la contoisie des gens de Surailec.
