Anyone used USB-C Riden TC66? banggood

It’s the exact same meter as the RD Tech TC66C reviewed by HKJ:

RD = RuiDeng, which appears to be transliteration of the Chinese company name , but it looks like they modified the brand name slightly to “Riden” so it’s likely easier to pronounce for the English world.

RD Tech (RuiDeng) has an AliExpress store (I’ve bought several of their items before) — it appears they now also changed their store name to “RD Riden Factory Store”

CT3 or YZ1280M? Someone help?

FL001

I think is good but it is not have Lightening port, so I choose WITRN-X-MFI.
I hope it is a good product

Is there any USB cable/cord straightforward resistance meter? Would be awesome if had these kind of connections:

Output:

  • USB-C
  • USB-A

Input:

  • USB-A
  • USB-C
  • Apple Lightning
  • Micro-USB
  • Mini-USB

Nice test

An interesting blog with posts about USB cable and connector resistance:

I think YK-Lab is the actual manufacturer. They call theirs the Shizuku by YK-Lab, and the outer case says Shizuku on it. I just bought the AVHzY CT-3, and if I look inside, the circuit board says Shizuku on it, and you can also see that in a picture of the UT18 on AliExpress. Also, the PC software and firmware are labeled as Shizuku, and AVHzY even has a couple links to yklab.org. I updated the firmware of my CT-3 using the software from yklab.org and it worked with no issues. I also found that in one of the information screens on the device that it lists AVHzY as the customizer, and their name appears in several other places within the software, so I think AVHzY, Power-Z, and ATorch are officially working with YK-Lab to sell customized versions.

Today is arrived WITRN X MFI…
Anyone knows if i can upgrade the Firmware?

Can anyone recommend a good USB -C charge for IPad gen 8 ( not an Apple product )

Would like to use it for Apple devices and Android devices and non brand name devices

Can anyone recommend a good USB - C battery pack that has a USB - C
output ( not a combination input / output )

Thanks

Anyone have any experience with FNRISI testers?

I’ve entered the USB-C realm, and am looking for something suitable.

I’ve been happy with my UM25C, so a TC66 naturally became a candidate, also helped by relative dearth of testers with male C connectors, especially moderately-priced ones. I don’t require the capabilities of those in the $50-70 range, but do want something better than bare bones basic, and can detect protocols.

Came across the FNRISI FNC88, which is comparable to the TC66, but priced more like the TC64.

After seeing a comparison photo in an AX review, I’m also actually kind of disappointed that the TC66 has reverted back to the smaller form factor, and is tiny compared to the UM2x series, with a small display. If that is going to be the case, the cheaper, comparable option looks more attractive.

One review has found both have their share of bugs, but the FNC88 has the advantage handling PD 3.0, which is my priority going forward. Don’t really care about the proprietary protocols. Spending less now and upgrading to something else after the market matures further also seems like a better plan.

At $14 it Seems like a good deal since it has all of the important features to look for in a usb c meter: bidirectional reading, PD switch, manual protocol enabling and multiple groups for offline data logging. I don’t find protocol detection very relevant these days, not like a few years ago. Maybe because I don’t have any device that uses Samsung, huawei or alike brands with high current fast charging. Most of my fast charge devices are now PD.

My AVHzy just died on me after testing two 100W PD powerbank. That one wasn’t designed to handle bidirectional current and I guess that’s why it failed.

Apparently 19 hours from now there will be a winter sale bringing the price down to $12.8, I will be ordering one to try.

Thanks for bringing the FNC88 to my attention, TheIntruder. :THUMBS-UP:

I couldn't resist to ordering one for $ 12.80. I will probably use it in my next reviews of flashlights with USB-C port for testing PD charging and reverse charging ("powerbank mode").

Yeah, it’s cheap enough to take a chance, so I’m going to order one as well.

It has a few issues, but there’s nothing else in that price range that’s comparable, and so does the RD.

USB-C, and its implementation, have had bumps, and is a moving target, but I’m glad to have at least hobbyist-level tools available, for not a lot of dough.

Oh that is a very interesting site, thanks for sharing!!

+1 :+1:
This is a good addition to HKJ’s tests and reviews. Thanks a lot for letting us know.

Received my FNC88. Two weeks from order to delivery, so not too shabby. Had read lots of complaints about Newgistics/Pitney Bowes, but it passed through their hands quickly, and bypassing the USPS system, except for the last mile, was probably a good thing, with its current delays.

My unit has firmware v2.20, so the screens conform to those pictured in the manual, and not the older ones used in some of the sales material.

Everything seems to function correctly, and the while I still wish the display was larger, it’s more readable than I thought it would be, and not like the similarly sized, but awful monochrome displays found on the cheap “J7” style meters.

The power adapter I’m testing claims to be PD 3.0 spec, but not PPS. However, the FNC88 does report PD 3.0 and non-fixed voltage APDOs, so it might actually support PPS, but given the loosey-goosey nature of these types of electronics, that can only be considered a guess.

It does what I needed it to do, and given the price, I’m happy, as long as it doesn’t crap out within a short period. The price actually dropped down to $12 even after that winter sale ended, but that’s AX for ya.
