Suraielec Watt Meter, Plug-in Socket Power Meter, 90V-250V Wide Range, Backlit Large Display, Auto Cost Calculator, Overload Protection, Kilowatt Wattage Voltage AMP Tester, Electricity Usage Monitor

Been having this ammeter/combo for over a month now on my 21cu/ft Hamilton Beach deep freezer to monitor cost-to-run. I FREAKING LOVE this product!! Great screen options (I leave it on cost per kWh by default). I especially love that I can set the wattage for overload-shutdown for safety. Having taken a week-long trip recently, I felt perfectly comfortable with it managing a shut-down if the freezer had malfunctioned. Awesome display and about as small as one can expect in the feature-set and capabilities. Feels solid and stays put in the outlet just fine. HUGE comfort bonus. On "that note," I was most impressed with how it WAS NOT BULKY compared to other meters offering similar features. I couldn't even get this larger "competitor model" to stay in the outlet…even without the cord plugged in!!! I'm very pleased with this purchase! 100%

Great value! Works well. I used this for two purposes: 1) Tested voltage output, the breakers and load put in my little generator. 2) Showed my kid how much leaving the computer on all the time ACTUALLY costs us in Dollars! If you're an information nerd or need to monitor amps/watts/volts, this is great to have in the junk drawer!

Got this for a few reasons and let me say it works better than I expected. Its very easy to use and easy to read. It has a back light that makes it easy to see when its in a dark space. It has some great uses, definitely good to have.

I'm using it primarily to monitor real-time amperage draw. I have not checked the calibration by putting another ammeter on the same line but the values that it displays seem reasonable and repeatable. Overall, I think it offers good value for the money. The only reason I didn't give it 5 stars is because the display is LCD and can be difficult to read unless you're directly in front of it. An LED display would be a great improvement.

This power meter does what it needs to do and seems accurate enough for home appliances. One quirk I noticed with the cumulative runtime counter is that it will not increment when no power is actively being drawn by the plugged in device. For example, I was measuring how much power our kitchen water boiler uses over the course of the day, and was puzzled when the meter only read say 8 hours cumulative time when I know that I reset it over 12 hours earlier, before realizing that the timer does not count when the water boiler is idling with negligible power draw. So the timer will not necessarily be accurate for devices that do not draw power continuously. The other improvement that would make this meter easier to use would be if the reset button wasn't one that required a pin to reset. The meter comes with one of those little SIM card eject pins, but it's a bit too sharp for the rubber reset button, and a thicker plastic pin would be easier to use, or have a raised button that can be reset by hand. It's a balance between convenient reset vs preventing accidental resets, but there are other ways to reduce accidental resets without requiring the pin (eg. put the reset button on the side).

Have had it for a little bit now. I like it! Best? Illuminated screen. That is a game changer. Wish someone would come up with one that can be illuminated 24/7. I'm sure that would be a more expensive version, but it would be a great difference. Top question is would I recommend this Watt Meter? Hands down yes!

I bought the Suraielec meter and a similar-price Ketotek meter to compare them. Both are reasonably easy to use, but the Ketotek has somewhat larger buttons for switching between modes. The Ketotek is also MUCH easier to reset when you want to restart the power usage measurement. All the functions worked as advertised on both units. I did not test for accuracy against a known reference, but the voltage was 120 +- 0.2 as expected. All other measurements looked reasonable for our toaster oven. The back-lighting makes the data very easy to read on both units. The Suraielect back-lighting goes off after about 20 sec (my preference), and comes on again when you next push a button. The Ketotek back-lighting stays on for several minutes, and also returns when you push a button. The biggest difference is in how you reset the cumulative kWh and time measurements. To reset the Ketotek, you push the + and - buttons simultaneously for 3 sec. To reset the Suraielec, you have to stick a small clip (provided) or a paper clip into a small hole. That's a nuisance and requires you to keep a paper clip handy when using the device. Consequently I returned the Suraielec and ordered a second Ketotek.

Es un dispositivo muy práctico y con el se puede colocar en diferentes equipos y según el cobro de tu país del kilowatt hora ver cuanto consume cada aparato y ver el gasto real. Muy práctico y así ver que más consume en tu casa y racionarlo o pensar en cambiarlo

Man don't think twice. It works and I love it. Shows volts amps and watts at the same time. Plug my coffee marker in to it and was surprised to see 9 amps of draw at 119 volts. Anyway that said that is why I bought. I can now see what and how much is on one circuit with ease.

Amazing product and easy to use!

Been able to track the cost and live wattage usage of my 3d printers. I also plugged it into an portable AC and the readings were decently accurate for the price point. Saves values after power reset, and only resets values through manual process. The fourth photo is a built in setting to set an upper limit to power draw.

Very good watt meter, and it has the level of accuracy needed to test power stations and battery solutions. It has an internal rechargeable battery as well.

Easy to setup and simple to use
