Review: 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.
Review: easy to use, works as expecteed. - Get a better understanding of how your electricity consumption is affected by each piece of equipment in your home. Put this on various appliances to see how much power is being used. Killers are the big screen TV and two freezers. Everything else is reasonable in comparison. Accuracy is unknown but seems to be tracking pretty well relative to current ratings of different items. Worth it to educate yourself and the family as to how much electricity is being wasted with things being left on etc...

## Questions & Answers

**Q: I have a toaster which occasionally trips my breaker. Will this respond quick enough to see amps drawn to determine if toaster problem?**
A: Thank you for your question.

You can get the below data with this watt meter:

Cumulative Value
√ Accumulated Time (only accumulate the time when the measured device is using power)
√ Electricity Consumption
√ Cost (need price setting)

Instantaneous Value
√ Watts
√ Amps
√ Voltage
√ Frequency
√ Power Factor

Peak Value
√ Max. Watt
√ Min. Watt

It doesn't record the instantaneous time so it doesn't work in your application.

Please feel free to let us know if you have more questions.

**Q: Can it read start up watts?  Up to 2000 W? Does it save the value?**
A: It does measure and track min and max wattage, but I'm not sure if it would read or track surge watts (as they are usually a fraction of a second)
Product description says the range is 0-3680W (30 amps at 120v), but after running my desktop computer (less than 700w) for a few minutes, it started to give off a burnt electronics odor.

**Q: Can I use to accurately measure inrush current? Does it register and save such brief spikes in current?**
A: Thank you for your question.
Here are some notices when using the watt meter.

1. This power monitor meter can measure 110-130 Vac & 200-240 Vac voltage; 0-16A AMP; 0-3680W wattage, and indicate overload when load up to 3680W, but the label on the product back only shows low volt range due to certification requirements.

2. This wattage meter only compatible with NEMA 5-15P plug & 5-15R outlet, so you will need an extra adapter to work with other plugs.

3. This wattage meter DO NOT work with AC inverter and solar panel inverter.

This watt meter is an improved version that can measure many data and has a class 1.0 accuracy standard. I hope you like it.
If you have anything questions, please feel free to contact us.
We will get back to you within 24 hours.

**Q: What values do I put in the “00.00” cost/kWh. I live in New York City. I am unsure what numbers go on the left side from the “.” & on the right side?**
A: You should check your electric bill to determine the cost of KWH in NY City. Whatever that cost is, this is what you will enter. If you unsure, contact your electric utility provider and ask them, as sometimes there are multiple billing plans that may exist within the same provider and depending on your location. As a rough approximation, you can also check your last bill and simply divide the total amount you paid by the total of KWH you consumed. This may not yield the exact cost of KWH as per your utility billing plan, but should be good enough an approximation to allow you to estimate costs with the Watt meter. As to what you should enter in the meter itself, let's say your local cost is roughly $0.14/KWH, so you would enter  "00.14" in the Watt meter.

### ⭐⭐⭐⭐ Mostly good points, a couple not so good.
*by T***R on March 12, 2024*

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.
