Upgraded Watt Meter Power Meter Plug Home Energy Monitor Electricity Usage Monitor, Electrical Usage Monitor, Energy Voltage Amps Meter Tester with Backlight, Overload Protection, 8 Display Modes

Absolutely love this product! The quality is top-notch, and it feels like it’s built to last. It’s proven extremely reliable so far, running smoothly without any hiccups. It also looks great—sleek and well-designed, definitely a nice addition to my setup. I've experienced a zero crash rate, which is impressive and speaks to the stability of the product. Every function works exactly as expected, and it delivers on all its promises. Best of all, the installation was a breeze—super straightforward with clear instructions. Easily a 5-star purchase!

They seem to work as intended, we use them to monitor usage on various household items to see how much energy they consume. This can help determine how important it is to us to operate that equipment given the high price of electricity which always increases.

No issues. Works well. Works in both directions. Works of your drawing power or pushing power. Used on solar panels providing power and used on normal outlets drawing power. Both were accurate

Claimed accuracies: Voltage: Plus or Minus 1%, Current: 2%, Power Factor: 2%.Results of my test: Voltage: Reads 1.5% low, Current: Reads 7-10% low, Power Factor 14-16% high.I bought a 2-pack, and both units agree within 1% of each other.Voltage was compared with an accurate multi-meter, my computer's UPS, and my old Kill-A-Watt tester, all of which agreed with one another within 1%. Current and P.F. were compared to the Kill-A-Watt tester only, using a pedestal fan, checking the 3 speeds (thus the ranges shown above).The voltage test is of high confidence (the 3 comparing devices), and the no-name tester is only slightly out of spec, so I have no complaints there. I have less confidence in the current and P.F. comparisons, since I only have the Kill-A-Watt device to compare it to, but since the K-A-W voltage accurately matches the multi-meter and UPS, I estimate it's current and P.F. readings are fairly accurate too.And to be fair, since the tested load was only 20 to 35 Watts, it's possible the no-name device's accuracy might improve with a higher load....I might test that in future. Bottom line, is that while the voltage is of acceptable accuracy, most folks buy this to check the current/watts, to monitor cost, and here it's of questionable accuracy. As to the Power Factor, as I understand it, power companies don't charge residential and small businesses for low power factors, so the inaccurate reading here is of little importance.So for ten bucks each, I cannot complain at all, just be aware you might want to calibrate your readings to a known good device before expecting the stated accuracies.

These plugs are sturdy and easy to use! Great if you wanna know your total kWh power output if you’re buying or renting a solar/gas generator for outdoor events.The two photos attached are from a recent 3.5 hour gig. 0.2kWh was just the DJ gear and the 1.12kWh was from the sound used. Both were plugged into separate surge protectors to get the data.

So good to know power useof various items.Always wanted one,does morethan I need at this time,but extra featuresare good!

Very useful. I use it camping to see power draw on my batteries.

The unit is so large it blocks the other outlet on a receptacle. Had to return.
