Bluetooth USB PD Tester Connects to Windows and Android/iOS Apps for Data Logging

We’ve written about USB-C PD power meters in the past such as Satechi USB Type-C power meter. Those allow you to measure (charging) voltage and current displayed on the screen part of the meter.

But thanks to Bluetooth and USB connectivity, Riden TC66C USB PD tester allows you to capture and log data over a period of time by connecting to a Windows program or Android/iOS mobile app. There’s also a version without Bluetooth – TC66 – that only works with the Windows program over USB.

We found out about the USB PD tester via Pete Scargill blog who tested both the Windows program and the Android app successfully as shown above. The USB PD tester not only measures voltage and current from which it derives the power but if I understand correctly, it can also detect if data pins are connected, measure/estimate cable resistance, as well as temperature.

Riden TC66 and TC66C USB PD testers are sold on Banggood for respectively $18.99 and $23.99, and you’ll find those on Amazon and Aliexpress.
