Can this be used with USB-A chargers or only USB-C
This tester has both a USB-A interface and a Type-C interface, so it works with both USB-A and USB-C chargers. You can test older USB-A chargers as well as modern USB-C PD chargers with the same device.
Can I use this to test my laptop charger?
Yes,this tester supports DC 3.2–30V voltage range and up to 5A current, which covers most laptop chargers (typically 19–20V, 3–5A). You can connect it inline between your laptop charger and laptop to monitor charging voltage and current in real time.
How accurate is this tester?
The tester provides a resolution of 0.01V for voltage, 0.01A for current, and 0.1W for power. For typical USB charging measurements, the accuracy is within ±1%, which is sufficient for everyday testing and comparison of chargers and cables.
What does the multi-color backlight do?
The tester features a multi-color backlight that changes based on charging status. Different colors indicate different charging states (e.g., standard charging, fast charging, full charge)
