TC66C-a powerful Type-C USB tester

thank you, you can use converter but the measurement values will not be that accurate, so it is better not to do that

Just make a limited run BLF edition with 2 female connectors :)

you can have a look at this:Elistooop 10Gbps USB 3.1 Type-C type c USB-C 24Pin Female to Female Extension Adapter connector for HUAWEI Chromebook Phone
it is not our product, but I think this one will not influence the result so much.

Now that is an idea! Id like to buy a BLF edition branded USB tester. I will also consider the coupler as well.

ok, friend
thank you

[Ordered 12.05, received 01.06.209 (21 days to kiev, acceptable) with delivery meest express. And then, the adventures began with delays, handed over to some “rosan”, he transferred to the usual post office at the place of residence, as a result, took in the mail only on june 10, t. e. It was only 300 days. The tester, very well packed in a sealed gold chinese seal :-)) branded plastic box with soft tabs, in turn, was placed in a foam box of two halves, t. e., to damage it would be difficult with any transport shipments. Turned on-works, high-quality color display, then we will test more in-depth. It is convenient that the link to download the user manual (in english and chinese) and software is indicated on the product page, very well and fully decorated and on the liner in a box with a tester! Good firm, good store-i recommend to everyone!]

TODAY’S SHARE
[Let’s look at the technical capabilities of the device. The coolest thing is that there is normal pd support (bidirectional), and the app for the smartphone. And most importantly, there are triggers. Can manually activate the output voltage of 9 v/12 v/15 v/20 v for qc and pd devices. This tester allows you to measure very accurately the capacity for example a poverbank with type-c output, because it measures voltage from 0 to 30 volts. Limit current measurement 5 amps. Resolution of as many as 6 digits: for measuring voltage 0.00001 v, and for current 0.00001 a. In addition, independent power via micro usb port. And a great opportunity, you can measure the power not only from the charger, but also back-from the type-c port of the smartphone or tablet. In this model of the tester, it is possible to update the firmware, this is undoubtedly a plus. The tester allows you to see the protocol used and switch it to another if it supports the power adapter In general, the tester perfectly copes with its functions.]

So, I have an interesting question.

Since QC 4.0 is based on USB PD, would it be possible to do a software update to see if a QC 4.0 charger is activated or not?

for now ,we don’t support
but later we will update it

[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.

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.
