## Customer Reviews

### ⭐⭐⭐⭐⭐ Great to verify USB-C power
*by P***5 on May 24, 2024*

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.

### ⭐⭐⭐⭐⭐ It is simple and effective, but don't expect ultra accuracy.
*by D***K on July 24, 2025*

It may not be very accurate, but it is accurate enough. It is also very simple to use. If you want ultra accuracy, buy Power-Z KM003C.

### ⭐⭐⭐⭐ Works well but expensive.
*by K***C on September 19, 2023*

This meter works well and is easy to read. Handy to tell if your device and charger are really fast charging. It is kinda expensive though. It does seem to pass data between my iPhone and the charger as I can watch the current ramp up over time.
