AVHzY Multi Testers Editorial Review
The CT-3 USB power meter is praised for its clear screen and accuracy. It allows users to test their USB chargers to ensure they are working as rated, and has options for PD and QC. The ability to provide external power to the device also allows for accurate measurement of the device under test. It can be connected to a computer for real-time data with Python or other scripting languages. However, the CT-3 has been reported to be finicky and has been described as "bad hardware and/or design" in some cases. Its single-button control system can also be problematic, causing accidental PD detection and risking damage to devices. Some users also find the menus difficult to navigate.
