Review: An Impressive and Accurate, Must Have Tool! - This Simple and Logical to use, brilliant bit of kit, allows you to check and confirm the output values (Voltage, Current, Capacity, Energy and Resistance) of USB A and USB C charging ports, whether that be USB Wall Sockets, USB Chargers or Battery Power Banks. The ET920 unit is a little smaller than I expected, being slightly smaller than a Credit Card and if it were just a cm or two longer and wider, it would be ideal but it's not the end of the world. The unit is robustly made, the screen is well lit and all data is clearly legible and accurate, albeit some a tad small. The attached input cables are a little stiff and if the USB Socket is 'the wrong way up' (if that makes sense), you have to twist the cable to be able to view the screen but I'd rather that, than suffer flimsy cables and the pluses outweigh the negatives. It does have its limitations, in that firstly, you cannot cross the cables i.e. USB A Input must be used with USB A Output (not USB C). Secondly and this could be a Major Issue for some users, if the Input Charge stops, due to, for example, a low input voltage value, which would happen if the device attached to the output port has become fully charged, the displayed values are NOT stored on the device and are therefore lost. Conclusion: To date, I'm impresses and Well Pleased with my purchase. It could be better but..... I'll update this review if necessary but to date, Highly Recommended!
Review: Useful addition to toolkit. - A well made useful tool from Klein. It will test the supply from a USB socket, show the supply voltage and how much current is being drawn from the item being charged. Well worth the money, and essential for troubleshooting phone charging issues: already found a dodgy wireless charging pad that was intermittent.

## Features

- 3 to 20V DC; Current: 0.05 to 3A (monitoring mode)
- Built-in test loads of 0.5A, 1A, 2A, and 3A; no external test load required
- Continuously monitor up to 1000 hours of voltage, current, capacity/charge delivered, energy, and resistance (calculated)
- Tests most common standard USB-A ports, including Qualcomm Quick Charge ports

### ⭐⭐⭐⭐ Nice tester
*by G***D on 21 March 2025*

A well designed USB power meter, it’s nice to have a unit with tails (cables) as it makes it easy to view the screen when plugged into difficult to reach sockets. Build quality seems good and measurement is accurate. I do wish however they included a power calculation and displayed the current load in Watts rather than just amps and volts with Energy.
