TC66C-a powerful Type-C USB tester

It’s useful and powerful, you can see detailed introduction by click Products link(very very long :laughing: )

Seems like good functionality for $21. Thanks for the test!

Does the PC software allow for logging and exporting as CSV/TXT file?

Why does the display and software report different voltages here, or is it just not connected:

I didn’t click “conncet” button so it is not connected at that moment, pc software can export data to an Excel file :crown: .

Great! Gonna get one.

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.

Same thing.

Will be ordering one.

Nice tester.

Since it can trigger PD, does it mean you could then connect HD35 to it and simulate a PD load?

Oh that would be amazing.

Seems like it is capable to do so.

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?

Yes,TC66 can be connected to PC in the same way, TC66/TC66C use the same PC software, but we cannot use APP to control TC66 or view data. :slight_smile:

yes,when connected to HD35, HD35 will be used as PD load, and you can choose PD mode at TC66C

almost forget that For this manufacturer, there is a big sale promotion for first publish from 28st-31st,

this is introduction vedio of TC66C

nobody wants to talk about it :question:

I’m in the market for one of those adjustable DC power supplies with a case. Any deals for those?

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!

Good question. I’d like to know the answer, too.

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:

Ah okay, thank you Pete7874! :+1:
Actually, I already have the UM24 that I like very much. :slight_smile:

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:

Where is the PC software?

The instructions refer you to this location:

But when you go to this location, there is only an .apk file there which is not a Windows executable.
