A compact, multi-function USB tester with a 1.44" TFT LCD colour display. It monitors voltage, current, power, capacity, charging protocol, and cable resistance in real time, with support for fast-charge protocol detection and PD active triggering.

The tester integrates USB-A, Micro-USB, and Type-C interfaces, with an external 16-bit ADC and PD protocol chip for accurate measurements. It can also be used to decoy voltage from a protocol adapter to create a simple DC regulated power supply.
