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

This meter works perfectly. I plugged my old basement freezer into it and discovered it was costing me over $20 a month. The screen is clear and stays bright for 30 seconds. I love that it doesn't block the second wall outlet. It feels durable and accurately tracks watts, volts, and costs. Great tool to lower your electric bill!

Works Great, for the price this solves so many problems for me. No need to buy those more expensive ones, this one does more than enough for a Watt Meter. Great Deal, Buy them now!

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%

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.

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.

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).

Excellent. Need for Hvac. This can go to 220 volt, unlike others selling here online. Nice that it has a back light too. Tested it on my little toaster oven. It was showing 1500 watts as toaster stated from manufacturer. Great.

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.

Only used it for a couple days, but so far it's working perfectly. For the price it's an excellent product, highly recommend.

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.

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.

Works good! I just with there was an easier way to reset it for a new reading monthly instead of deleting everything and then inputting the KwH rates.

Great for balancing electrical loads on older home circuits. Checked readings with appliance ratings and found very accurate.
