USB-C cable tester for engineers and technicians

The POROMETISTO UT01C measures DC voltage from 3.3-40V and current from 0-12A, displaying real-time power up to 240W. It captures capacity in mAh and energy in Wh with power-off memory. The unit supports PD2.0/3.0/3.1, QC2.0/3.0/4.0+, PPS and BC1.2 protocols, plus PDO/QC spoofing and E-marker simulation for charger development and cable validation.

Passive operation with corded electric supply

The tester draws operating power directly from the circuit under test, so no separate battery or mains adapter is required. Its measurement circuitry adds minimal insertion loss while monitoring temperature alongside electrical parameters. The corded design keeps the probe fixed to the display, avoiding loose connectors during bench work.

Sustained load monitoring up to rated limits

Continuous logging tracks maximum voltage, current and power values throughout a charging session, while ripple analysis reveals supply quality under load. Protocol gear spoofing exercises the charger across its full operating range without external triggers. Capacity accumulation and temperature data remain stored after power removal, enabling post-test review of thermal behaviour during prolonged operation.

Questions about this item

How do I connect the UT01C tester between a charger and a device for inline measurement?

Plug the tester's USB-C input into the charger and its USB-C output into the device; the display then shows live voltage, current and power.

What ongoing care does the UT01C need to keep readings accurate?

Keep the USB-C contacts clean and store the unit dry; no calibration or battery replacement is required.

At what power level does the UT01C hit its measurement ceiling during a long test?

The tester measures up to 240 W, so sustained loads above that will exceed its range.
