USB-C Power Analysis Tool

The T3 USB C Tester measures voltage, current, power, energy, capacity, ripple and line resistance on a single device. Its 2.5D touch screen presents live charging data for cables, chargers and power banks. The unit operates from 4.5 to 50 volts and handles loads up to 600 watts.

Diagnostics for Engineers and Builders

Technicians and DIY users gain instant visibility into fast-charge handshake behaviour and cable quality without a bench oscilloscope. The tester does not trigger USB Power Delivery contracts, so developers who need to negotiate specific voltage or current steps must use a different instrument.

Ripple and Resistance Measurement

The defining capability is simultaneous power-ripple analysis and accurate line-resistance testing, revealing noisy supplies or high-resistance cables that cause slow charging or device stress. This single function separates the T3 from basic voltage-only checkers.

Questions about this item

What type of USB-C power source do I need to connect for the T3 tester to display readings?

Any USB-C charger, power bank, or laptop adapter delivering between 4.5 and 50 volts and up to 600 watts will power the tester and show live data.

Will the T3 tester work with my older USB-A chargers if I use a USB-A to USB-C cable?

The tester only accepts a USB-C input, so a USB-A source requires a USB-A to USB-C cable; the T3 will then measure whatever voltage and current that legacy charger provides.

How can I confirm the T3 tester is measuring ripple and line resistance correctly after I plug it in?

Switch to the ripple and resistance screens on the 2.5D touch display; stable waveforms and a low resistance value indicate the tester is capturing those parameters properly.
