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
Sample informative video:
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.
Just got my FNIRSI FNB28 and FNC88. These meters are tiny! Agreed with what TheIntruder said, and to add:
For the price I probably shouldn’t be complaining ($10 and $12 respectively), but the build quality is really lacking. The PCB are thin and flexible, the male USB port was wobbly from the factory, the screen on the FNC88 isn’t installed straight and the screws on both meters appear to be torqued down by a 1 year old infant. Soldering job on the components seem ok, but they used the least amount of solder possible for the masks.
Although they seem to execute the functions well: PD trigger, bidirectional read, output volt select, protocol detection, data line sensing and offline 5 group storage, these are very light duty meters to casual testing chargers and devices. Definitely not on the same level as compared to a YZXstudio or AVZhy meter. I wouldn’t test a 3A load for extended periods of time. They also give you a very cheap feel because of the generic times new roman font, which I believe is the default english font for chinese OS and programming platforms.
Surprisingly, they ship these in their own case and then inside a foam box, better packed than 95% of the stuff I’ve bough overseas, and arrived extremely quick given the current circumstances.
I don’t recommend these for any serious testing task, but again you shouldn’t be spending $10 if you needed real testing equipment. But for most people I guess these work just fine, one of the worst things with PD is the charge rate uncertainty, I have a HP spectre 14” laptop that is really picky with the chargers and even detects when the charger has something else connected to it and reduces the charge rate. This small meter is perfect for that task.
I didn’t disassemble my example for examination, but on the surface, nothing is askew, or loose.
Nor I have handled one of the higher end meters, so I can’t compare their build quality, but I do find it ironic that none of them can be bothered with even a rudimentary case molding, when the cheapest meters do. At least that would alleviate some of the need to handle the bare-PCB style meters with kid gloves, regardless of price. More than once, my fingers have slipped and done an LCD mashing like kids do when curious. Look at the neat effect when pressing on the screen!
USB-C and PD are a can of worms, so it’s nice to at least have a cheap way to help sort it out.
I picked up the FNB38 during the winter sale and it arrived a week or two ago. I’ll hopefully be able to put it through it’s paces soon.
