Very good quality USB C tester, aluminum body, charging and data passthrough, very good display, charging stats, reverse charging, charging graph, ripple, protocol, e-marker, gyroscope for screen rotation, internal temperature, many buttons, easy controls, good settings, no internal battery, many functions I don't even know how to use.

Brilliant little device, even functions as a sort of oscilloscope and spectrum analyzer when measuring ripple, with different time window setting. Sounds like it can also act as a PD and even PPS trigger too, but would need much care as to what you connect it to! Would be good if they did a version with a larger screen and buttons, but that would also cost more 😀

The best usb-c tester. Most features for good price. Shows measurement immediately when plugged in. No boot delay, unlike the HiDANCE / Atorch 13 in 1 that takes 10 seconds to boot. It has built-in PD trigger, turned on by physical switch. It can show PD 3.0 and QC modes supported by power supply. It shows a chart of the measurements. It has voltage ripple measurement, outstanding feature.
