Works as well as advertised

Move along, move along...
Do NOT bother with this item. It's a simple device and priced at a significant premium to similar devices so you expect a reasonable degree of accuracy - but it's absolutely miles out. Wish I'd read the other 1* and 2* reviews first! The seller must surely be aware there is a problem but when contacted was unhelpful. Functionality - very simple compared to others. Accuracy - very poor. Readability - decent screen but does not rotate so annoying. Value for money - zero.

Great little display
This has proved to be insightful in monitoring both problematic USB devices, and interesting to watch whilst using/charging other USB devices. I haven’t found anything it doesn’t work with yet.

Great device. With this I can see the power consumption of my ESP32 devices as well as charging power of my laptop and every device in between.

This is about as simple as it gets. Plug the monitor inline with your device and see how much power you're using in watts, amps, and volts upto 240 watts (the current maximum). Cumulative energy delivered in watt hours is also displayed. This information can be used to verify that your cell phone is charging at its maximum rate, or that your power supply is providing enough power for your computer to charge. If the display is off, no power is present. Did you plug in your power supply? Is it broken? Is the cable good? These questions can be answered with this simple device. It comes in a nice tin box for easy storage and protection.

I suspected motherboard damage but this awesome tool let me know it was a bad power supply. Easy to use and works great.
