HBN Watt Meter Plug with Backlight, Plug-in Socket Power Meter Electricity Usage Monitor Consumption Home Electrical Energy Monitor, Voltage Amps Wattage Electricity Usage Tester, 9 Display Modes

I used this Watt Meter to determine loads for a generator, plugging it in between a generator and couple of space heaters to determine wattage and loads. There are several settings to choose and it worked perfectly. The blue-lit LCD is large and easy to read under all light conditions. It can be easily used to determine the real wattage any appliance is using. Simple, efficient, and fairly well priced.

This is insanely helpful. Some basic math you can do general estimates, but when it comes to devices that cycle, such as heaters. heaters heaters heaters its always the heaters, these don't just run 1500 watts constantly, they do it in cycles and this here is so helpful to learn how often they kick on, and their true cost that you don't see. I would buy this again, its been helpful. I juse wish the buttons were easier to use, I don't care for that. The UI isn't the best either but it still works fine. They should just make a dedicated button for certain tasks instead of having to long press other buttons.

2025-07-27. Watt meter plug by HBN. Backlight. Electricity usage monitor. Electricity usage tester. 9 display modes. Voltage. Amps. Wattage. This is advertised as an electricity usage monitor, but I can't see any real practical use for that purpose. So you know how much electricity your appliances are using, and you can even calculate the costs, now what? I suppose if you're on a really tight budget, you can cut off using electricity, but rather than cutoff something we essentially need for sustenance, I'd recommend you trim the budget elsewhere, carpool and share the costs of fuel, or eat out less, but don't cut off your power. Of course this doesn't mean you should leave all your lights on all the time, save where you can. If you're not in that room, turn off the lights, set your TV on a timer in case you fall asleep, or change your bulbs to energy efficient LED ones. So why did I order this? Well, I use it to test the capability of other devices. I already own a USB A/C wall block that is supposed to be capable of delivering "Fast Charging" which is technically 18W or greater (up to 100W). Wattage is a simple formula of Volts × Amps. My charging block is capable of up to 25W and I wanted to test that it would indeed draw more than 18W. Usage is super easy, it's essentially "plug n play" meaning all you need to do is plug it in and turn it on (if applicable). This unit does have some settings, but I was interested in the wattage, so that's the one I had set it to display. After plugging the unit it, it instantly powered itself on and setting the display was as easy a push of a button. The one notable I have really is the display itself. It does have a blue backlit LED but this is both good and bad. It's good in the sense that if you're in a dark place, the illumination will make it easier to read; however, the opposite effect is also true in lit environments. I had the light turned on and at certain angles, it was not so easy to read (see pics). This could have been easily combatted by a button for the light, but the good news is that the backlit LED display will turn itself off after about 5 seconds. Again, there's a flipside to this, and that's if you want it to stay on because you didn't quite read the readout yet. There's not much else to this unit, it can display Volts, Amps, and Wattage, which is what I really wanted it for, so it's very functional for my needs. The controls are very simple and easy to use with its plug n play interface, and the unit feels solidly built.

Delivered 3 days ago, and used with ease. Simple, well designed and works. For 3 days it has let me realize how much electricity I use and the cost of it has become. So far it's working as designed.

I purchased this device to determine my wattage on items I use in my 5th wheel RV when operating with an inverter so I know exactly what I can use combined without overloading the system. I also use it when fine tuning my generator to set the proper hertz for it. Great unit. One draw back is that the great blue light does not stay on while in use. It turns off and makes it difficult to see the panel if you are in low light conditions. Solved by unplugging and re-plugging the unit, but just annoying.

Lo use muy poco pero es una gran o opción para monitorear el consumo de energía. Muy recomendable si quieres cuantificar ciertos equipos

Bought this because my electric provider keeps saying I am having energy spikes when I am not using much of anything... The various features come in VERY handy to know EXACTLY how much electricity you are using with each electronic device & in a very detailed yet easy to understand manner. Honestly after using it I think that every household should have one quite frankly...

No cuenta con ninguna certificación o norma de seguridad, algo que esperaría que tuviera un producto de este tipo. La caja dice que el dispositivo fue diseñado en California, y hecho en China. Sin embargo, las instrucciones, que están en inglés, están tan mal redactas que dudo que ese sea el caso. No quise usarlo por mucho tiempo ya que temo que vaya a dañar algún aparato o prenderse en fuego (como lo mencionó una reseña de EUA).

I thought this would be a cheap plastic thing, but I was Very relieved to see how solid. It's a brick. It does everything as advertised and I like the fact it monitors voltage and frequency and amps too. I would and will buy another for sure. Recommended.
