new share
[very fast delivery and great packaged! The measurement of voltage and current ist very accurate and you can connect it over bluetooth or usb with your computer / handy and collect the values (for bar graph etc). The main rail ist usb-c and the connectors fits very well (after I removed some dirt from my cable connectors:) ). I can recommend both, Item and seller!]

I'm sure your product is nice etc., but I think this aggressive marketing - re-posting each review from Aliexpress almost ever single day just to bump thread, may be counter-productive. Those who want to read reviews will find them on your Aliexpress listing anyway.

Yeah, it’s a bit extreme.

Agreed. Please stop.

coupon topic:

Just got a TC66C yesterday. All is ok, pc communications included, i am very satisfied. But i cannot update the firmware (it shipped with 1.12 while there is 1.14 available).

I followed the procedure, pressing K1 while connecting it to the PC: the TC66C shows “BOOTLOADER 1.06” and the pc software says “inserted” but when i click on Update Now the software hangs and do nothing. The display on the T66C keeps showing BOOTLOADER line.

Someone could help?

Hi friend
thank you for your message, yes, I can help you , don’t worry, could you make a video to show the problem

well, my tc66 just stopped turning on when putting in to usb-c after 4 days. Yes, the pwr switch is on, have to hook up a powerbank to the microusb for it to light up.

That did not last long

Hi friend , could you make a video to show the problem and contact me by email 1749808860@qq.com

I got it up again. Did go through the process maybe 6-7 times and its working again.

-pd softswitch off and on
-pd swith on the back off and on

Did that 6-7 times and it finally detected it again. Was testing phone charge so had turned off pd, but seems to have been a bug turning it on again.
on fw 1.14

please use a video to show what you said and problem, i can see that clearly

Good Morning,
I bought my TC66C last week.

I live in Brazil and I believe it will receive around 40 days.

The post office in my country is very slow.

thank you for your support, and usually it takes 20-25 days to Brazil.\
recently it is fast, one year ago, it is very slow , sometimes it is more than 60 days

what should you do if TC66C cannot upgrade firmware:
if you see the interface below when upgrade the firmware, please delete the software and install it in another disk(DO NOT INSTALL IN SYSTEM DISK)

RD tech- Im curious as to which charger you are using on page 1 (C66C can test the maximum power of PD charger, so that we can know the quality of our charger)- It looks like it is capable of PPS 45 W
what is name/model number of it?
thanks

It’s XIAOMI ZMI HA832 65W charger :wink:

Thanks- I don’t mean to hijack the thread but have you come across any chargers that do pps 10v-4.5A (like the samsung 45w charger)? p.s. love the functionality of the TC66!

sorry for that, I don’t know that, usually I see 45W charger use 15V/3A or 20V/2.25A, you can ask someone else to see if they know such a charger
