The product uses a highly integrated microcomputer chip and dedicated electricity metering chip in combination with highly precise current sensor and LCD display to recognize overall monitoring of electric equipment.
Simply plug the meter into the wall socket then plug the appliance into the power meter. It helps user in saving money and energy by identifying power consumption of each appliance. It has wide working voltage range of 100~260V.
Backlight function making it easy to read data even in the dark. Button is designed for easy operation and very convenient for daily monitoring of electrical appliances thus making the energy consumption clear.

I got this to monitor the power consumption of an appliance with a nema 5-20 plug. The contacts in the receptacle do not make contact with with the horizontally oriented blade of the nema 5-20 plug. I had to slightly modify the contacts by bending them to make contact but can't recommend others to attempt this as it is a fire hazard if not done properly. The receptacle worked fine with a standard 120v plug (nema 5-15). It will also not work with a nema 6-15 plug due to the same issues with the nema 5-20 plug. I live in the usa and can't test it with other international plugs.Tldr: works great with standard 120v plugs doesn't work with any other plugs found in the usa without potentially hazardous modifications to the socket to make proper contact with the blades of the plug.

一見すると200Vタンデム型をそのまま使えそうな形状ですがまずオス側コンセントは3Pであり200Vタンデム型等に適合しませんアタッチメントなども付属していません200Ｖ→100Ｖアダプターを使ったのですが今度はメス側に200Ｖコンセントを指してみるとグラグラしていて通電しませんでしたそこで写真のようにメス側にも100V→200Vアダプタを指してみると使用できましたしかし明らかに不格好であり安定性も欠き、万が一100Ｖ機器を繋いでしまうと怖いです常用はちょっと難しいのかもしれません尚100Vの電力量計としては正常に使えますがオスが3Pであり普通のコンセント機器に繋ぐにはやはりアダプタが必要です

Used to measure the power from my 230v 1.5hp air conditioner and the plug melted to the power meter. Meter went dead. I had to cut plug off and install new plug. Ac works fine without meter. With meter ac would turn off and on. Defective?

It does measure power and voltage quite well. The screen is easy to read as long as it's not in sunlight. And it works with high power outlets and international plugs, which many similar products don't. But its physical form factor is poorly built. It only fits into an outlet one way, and covers a large area around the outlet (e.g. the other plug in a dual outlet). In some places where I used it (measuring under the sink where a hot-water heater is plugged in) it could only be read upside-down. It would have been much better if it just came with a 6-inch extension cord between it and the power source. Then it would plug in anywhere, and the display orientation would be de-coupled from the plug orientation. If you want to use it outside the US, realize that the plug on the back of it is a 3-prong US plug, so you'll need a separate adapter to adjust it to the local outlets. The outlet on the front of it handles a myriad of different international plugs.

The device worked okay and seems to take accurate measurements. But the build is very flimsy and the plug on mine was barely functional and required a lot of force to get the device plugged in to it. Not super impressed but it does work

El medidor funciona bien aunque el contacto no es de buena calidad. Yo lo compré para medir lo que un micro inversor puede inyectar a la red, pero el medidor solo marca OL Overload.

It was the only option I could find on Amazon US that supported 220v. It does the job it's supposed to do, but the design is terrible.Why the US plug? I understand it's a US store but as far as I know the US plug isn't used with 220v. No problem, I used an adapter. Also, the way it's oriented forces me to plug it in upside-down.The way the UK style plug is connected forces the cable in front of the screen. See the picture above. Hilariously, the instruction manual and some of the pictures on the item description show it facing the "correct" position.In short, I needed an adapter to plug it in, had to plug it in upside down, and the plug for what I'm measuring can only be plugged in so that it obscures the screen. Otherwise, it performs the power meter function just fine...

Seems to work very well, the female plug holes seem to universal international fit, a bit weird

I use it primarily to see how much power my devices are using. It also measures current, voltage frequency, kWh used and co2 emissions. Plus it has a backlit display so it's easy to see the screen.

Multi functional in the front of meter. The back, however, has only the regular two prong 110V. This does not allow you to plug it into the original power receptacle for use. Totally useless item.
