I especially like that it supports power going both ways. First I was worried that it’s not possible to measure a USB-C PD power source with a fixed cable, but you can just stick that into the “output”/female port and the “input”/male port to the device being charged.
Is the only difference between TC66 and TC66C the bluetooth board? Can you still use the TC66 to connect to a PC and log data and perform firmware upgrades?
almost forget that For this manufacturer, there is a big sale promotion for first publish from 28st-31st,

Stupid question: How can I use this nice device with USB-A ports (both in and out)? Can I use adapters (USB-A to USB-C, microUSB to USB-C) or is it not recommended to use adapters? Will adapters have any influence on the results measured by this device? Thanks for your feedback!
Using any kind of cables/adapters can certainly increase resistance and impact readings. If you want to avoid having to use those, for USB-A, look at the UM25C:
RD Technology also sell adjustable DC power supplies but you need buy case in their store and build up by yourself, It is 328 festival so you can buy that at a inexpensive price,just have a look at RD technology or other stores, buy the one fits you. :sunglasses:
you can use adapters but it will influence the accuracy of the result because of its resistance, the Micro-USB port of TC66C is used for independently charging, so this device is designed for Type-c port. hope it helps you :student:
they give me a product , then I test it and write an article so that I can get this beta TC66C for free, :laughing: you can just have a look at their eshop,they have their own factory. https://rdtech.aliexpress.com/store/923042
