Watt Meter

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%

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!

Excelent quality, ease to use.

This product works well, it helps me to know the amount of current flowing through my circuit. It is so easy to use, I just have to plug it in. The Readings are near to accuracy.

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!

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.

It works fine and as others noted it doesn't interfere with the 2nd socket. HOWEVER if you want to know how much power is drawn PER DAY (or other unit of time) this thing only accumulates actual running time. So after one day elapsed it might show 2 hours. So you can't calculate usage - such as if you wanted to connect the appliance to a solar generator - unless you track elapsed time yourself. I think this is a major shortcoming. My own fault for not noticing it doesn't perform what seems like a basic function. I would not have purchased if I realized it beforehand.

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).

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

Excelente producto, vendedor recomendado

Easy to use and analyze power consumption and cost. The readout display is very clear and bright. Very sturdy quality. Recommend to you.

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.

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.
