Hi guys, I payed Richard a visit to check this usb diag tool for my self. And I must say this is really a nifty tool that stands out. How many times did I connect a printer or a smartphone with a usb cable and it didn't show up on my laptop. And by trying different laptops and different usb cables they did show up leaving me in the dark for the reason why. Well thanks to this usb diag tool, now it shows me why ... a) usb cables seem to have different resistance b) some laptop usb ports deliver limited current c) some printers or smartphones have poor handshaking signals ... and this usb diag tool shows you exactly all these issues in a visual way. It even shows you the capacity and efficiency of your laptop battery, phone battery or used powerbank ... and so on. Thumbs up for this FNIRSI FNB58 USB Tool.
Very handy device. The feature that looks most interesting is the scope. It shows clearly the pulse modulation and amplitude which is helpful to see the efficiency and power of the charger. I am looking forward to seeing the capabilities and uses in your videos. I enjoy learning tips and tricks from your channel.
"on off. i wonder if this is it." best senior moment ever,
Yeah it was one of those moments LOL - but you see this channel is the real deal 😁
you have to flip the pd switch to check for usb protocols, you didnt read the manual on any of these procedures and are not helping anyone with this..
And he did the resistance cable measurement completely wrong
I have had one of these for a couple of months now and love it, you should read the manual, you can long side press on the toggle to change the time base of the scope.
It's resetting during certain tests, protocol detection attempts etc. etc. because it needs constant power supply, independent from devices being tested. You have to connect that independent power supply to microUSB "PC" port.
@LearnElectronicsRepair, Thank you Richard for the video, so I did watch someone do the PD Listener mode (dont remember who) but I do remember him saying that on this PD Listener mode ONLY you have to power the FNB58 with a different source than the one you are monitoring (He used USB A In) he then connected USB C(Input) to charger and USB C(Output) to a device to charge, and he was able to get PD Listener to work, Thanks for all your hard work
Cable resistance needs a reference to be set with a constant load on the power source, BEFORE attaching the cable. READ THE MANUAL!
Yeay, otherwise all cables will be 000 ohm / null
how to provide constant load?
@andrikurniawan531 use the meter to determine that. Charge a phone or something.
Amazon has a DROK for less than $15. GreatScott! builds one with not much more than an op-amp and an FET.
What a lovey useful device. I've just ordered one. Thanks for the review.
Thank you so much for the great practical review.
very good review :) looks like an interesting product :)
Fascinating! I'm tempted to swap my Eversame USB Voltmeter Ammeter, with this one
Great honest review,thanks
It’s not often that you see something which provides info that is so helpful and not obtainable otherwise! I have been using 12v from bench PS to a usb power converter (for car) to measure power draw but that is so primitive compared to this little thing.
Bring on the purchase link and we can purchase it and in doing so , support your brilliant channel
The link is in the video description 😉
Thanks for the review Richard. I like these little testers. And as I don't yet have this one, the wallet must come out again 😁.
I especially like the large screen on this model & also the fact that it seems to respond pretty quickly. I remember some of the early ones being pretty poor in that regard, so each click going through the menu options would take seemingly ages 🙄. Anyway this one looks much improved👍
Cheers mate

Did you ever read the manual? For checking cable resistance you need to do two measurements. One with the meter directly connected to the charger, one with the cable you want to measure the resistance between the charger and the meter. During both measurements a constant current load needs to be connected at the meters output with about 0.5 - 1 A.
1. Connect the charger directly to the meter and to the meters output connect a constant current load with current set to e.g. 1A
2. press the buttom, the current voltage value will be stored as reference for the 0 Ohms cable
3. connect the charger to the meters input with the cable you want to measure the resistance of (to the output the constant current load is still connected with the same load current)
4. now the cable resistance is displayed
Bought one recently....blimmin nice little thing.
Just picked up one of these a week ago to do some testing on my various wall plug USB supplies. It's quite interesting to run the Fast Charge capabilities test and see what they can actually provide to devices versus what some of them market themselves as. This tool certainly has its quirks but for something around 50 bucks, it's hard to complain about value for money. Plus, the physical build quality seems to be pretty good, with the metal case being nice for durability.
Were you able to calculate the current drawn by the device, and if so, does the displayed values reflect this, or do we need to allow for that? Great video as usual. Thanks
pretty sure the USB C with double arrow between it and micro USB are both inputs, the other C output with the single arrow head pointing toward it. I have one it is great
Just Bought One..lol...Wonder if could Mod it to Getto Scope...
I have the old version FNB48, you need read the manual (the manual for my version is bad) but they have a loot off config. In every screen iff you push to right and keep a few seconds open a menu if you do to the left open other menu .
There's is a function to make go to defaults every time you unplug what you are test (is bad if you plug a 12v and the device still in 12v after you unplug one device and whant to test other that work in 5v)
what is the different beetween this and fnb48p?
I got one of these....
Pretty good as it allows me to see why the battery goes down in PostmarketOS on a phone and now I know I have to bodge in a charge regulator for 88% (4.2v out of the 4.4v LiHV).
I've just started watching, so I'd see if there are features I missed.
Hopes that there'll be some open-source firmware in the future though for features.
Warp/Dash/Vooc/Super Vooc are charging protocols for OnePlus ohones, up to around 60 watts I believe.
Hey Rich, would be a great addition to your review content if you could blag an extra item off the supplier to give away to your subscribers and even better a nice discount code or voucher to save a few quid on said item? Just a thought....love the content👍
You know what that sounds like a really nice idea regards give aways - I will try it. Regards discount vouchers I sometime get and publish them but you are right, I should be asking for them if they are not offered already - watch this space 🙂
Do test real world wattages, do you need a USB load tester as well? But no additional PD trigger?
What cable should i use to connect laptops USB-C male to USB-C male (what standard)
Cool TOOL. 😁
It has lots of functions and PD/QC triggers for technicians. From your video, the difference between FNB58 and FNB48S is only that FNB48S has no outer shell.
I came across your video while doing research. I have a question for you. I want to test the 20 Volt/12 Amps 240W SUPERVOOC charging adapter and find out its actual values. I want to measure directly at the adapter output and I want to measure from the cable output after plugging the cable into the adapter. The adapter has a TYPE-C output, 240 Watts gives the value as 20 Volt/12 Amps. I have researched a lot of products, there are products that see 240 Watts and can reach much higher Volt levels than 20 Volts, such as ChargerLAB Power-Z KM003C - Power-Z C240 or PLUGABLE USB C Power Meter Tester 240W, but these testers are not in the Ampere range of the SUPERVOOC adapter (I need 20 Volts/12 Amps, but I could find a maximum of 6 Amps in the meters I researched), so I think a healthy measurement cannot be made. What can I do about this, how can I reach the correct measurement, is there a device you can recommend?
1:58 - The in arrows are pointing to both the USBC and the MicroUSB; maybe the microusb is in/out?
did you turn on the pd swicth on the bottom
Mine show error code 02 when power up with power bank. Is there a way to fix it?
I came for the tester video, I left wanting the S60 soldering iron...
I want something like that that can also test the capabilities of the cable... is it usb 3.0... 3.1 er 3.2 and 3.2 gen 2 and gen 2x2 (i think I got that right?)
bonus points if it can also tell if it can do thunderbolt 3/4 + USB 4
Can it check usb4, thunderbolt 3/4 cable?
Good good video, I like to see a USB-C cable connected direct to DC power supply to see the consumption. If anyone knows how to build that will be great for technicians. Thanks
This or ChargerLAB Power-Z KM003C ?
Dash one+one proprietary usb.
I just bought this tester and wanted to test a "26800mah" power bank I bought from Amazon. I don't quite understand how to read the results that's right in front of me. Lol. Is it a 9900mAh or 19600mAH capacity?
Screen says the following:
Battery CAP Calculation
Group: 01
Time: 0 days 14:36:41
CAP: 9.92364 Ah
NRG: 80.5495 Wh
BAT Vol: 3.7V
Conv Eff: 90%
Results: 19.5931 Ah
Thanks!
Kann der FNB58 mit aktueller Firmware nur 120 Watt? In den Spezifikationen steht maximal 120 Watt! Das schwächste PD3.1 Ladegerät kann 140 Watt! PD3.1 selbst geht bis 240 Watt.
so the bluetooth is there only to connect it to the app on the phone/pc?
I didn't try it as I was happy to just connect the USB to my PC, but I expect you can connect to any BlueTooth device and run an app to log the USB tester data etc, Maybe FNIRSI can comment here?
@@LearnElectronicsRepair For Bluetooth you would have to install their Chinese app which I won't do so I got the version without BT.
Heya, nice and handy tool but don't know if I would buy it
I want one.
Sent mine back. Just too many bugs and now the app is missing from their website.
What if the charger comes with USB c only, there's no USB c male on the tester
I saw theirs a firmware update to 0.67
No if only there was an adapter for the usb 3.0 micro b female to usb-c. There doesn't seem to be a way to test external hard drive cables.
Very good "Executive Summary", could you please make a video of how to do the firmware upgrade?
Bought it, tested. Impression: too faulty. USB-C (Apple PD3.0 charger in) to USB-C (iPad out) , PD switch OFF - does not show the charge on iPAd. PD switch ON - same. However, after numerous ins/and outs off the wall charger and PD switch positions the charge showed up, suddenly. I did switch the cord only and again - no charge. Same as it was a minute ago - no charge shown on iPad, no current on a device. Then, after dance around (btw, there is no manual whatsoever), it started working. I looked at the sequence what I just did (every sequence were started with everything plugged off) and it was much different then previous one. Then I repeated from scratch over and over again (same good certified cables), every time the sequence getting tester work was different.
This is why I'm stating - device is faulty. I've tested with iPhone and iPad.
Now I understand why there is no manual - to describe the steps to get to the point is impossible - no repo-steps whatsoever
Hi will the USb58 help to sort out my car usb a socket. Problem is when connected to iPhone 12mini and use car play the battery gets very hot. I want to send data collected to the car manufacturer. Thanks Alistair
the control wheel fell off mine after 4 days
Is this a sponsored video?
Edit: says at the end it's sponsored. Rich could you put the fact it's sponsored in the description so it's clear the item was sent to you?
It's an odd one - I had just composed an email to Richard as I didn't see a youTube banner as is usual with sponsored videos - but when I refreshed the page a small barely visible banner appeared for maybe 3 seconds. It seemed rather obvious that this wasn't the first time that he'd had hands on one of these - despite some poor bumbling - he knew his way around the controls, and which bits he wished to use, for the first use. A very clever guy, doesn't need to play silly buggers.
@@will_doherty Exactly.
@@will_doherty Actually you are quite wrong on that front - I never touched one of these (or any previous versions or competitors models) before. Prior to recording this video I had a quick look around on the net to see what others thought of it, how they used it, and then dived right in with my own take on it. And it really was intuitive to use and I am not faking that. When I published this video I clicked on 'this video contains paid promotion' which is required by YT T&C and it should say so clearly to any viewers at the start. Just to clarify, this product WAS sent to me by FNIRSI FREE OF CHARGE and I was asked to give an honest opinion. I was not paid to make this review other than receiving a free sample and I had full control over the actual video content and my opinion of the device. I chose to demonstrate which features I personally thought were the most useful for repair work. At the end I thanks FNIRSI for sending it to me for review, so there should be no misunderstanding about that. I'm sorry if I caused any confusion, in future I will go back to explicitly saying when I am sent a freebie to review, as I normally do.
@@LearnElectronicsRepair Thanks for your response - appreciated.
@@LearnElectronicsRepair Thanks for clarifying. Your videos are great, you're really funny and informative. Hope my comment didn't offend.
28 degrees c, you lucky so and so.
How do you buy genuine and avoid buying a Chinese copy?
Cheers.
Be better if you’d had a quick glance at the manual, rather than working by trial & error. (I could do that)
Any device still using Micro USB (for the PC connection) is a no for me
69.64 Canadian that's a little steep...
...five decimal place, microvolt resolution, better than a 5-1/2 digit multimeter 🤣🤣
You are setting the reference each time, not reading the resistance!
RTFM why do you give a review if you have no idea how it actually works.
I always take things 'as they are' and see if they are intuitive to use. A well designed device should not need a user manual and this one did not even include one. Sorry if you don't agree with this approach but it is my way of doing it. Let me ask you a question and please be honest with the answer, OK. Do you own a car Frans, and if so did you read the user manual? Because they all come with one as new. And they have more buttons to press than this little thing does 😉
@@LearnElectronicsRepair Yes I do own a car and yes, I did read the manual like I read any manual for the same reasons that I watch RUclips videos. This because I hope they will be informative and hopefully show me how they work and teach me something I might not yet know or otherwise have missed.
Felix Immler has hundreds of thousands of views on his tips for Swiss Army knives. You would think that everybody knows what they can do with a pocketknife right? He gets these views because he has clever tips and tricks and therfore his videos are very informative.
Your video shows incorrect information so your viewers will either learn nothing or they might not buy the device because they think it can not do what they need it for. Your video is sponsored so in my opinion just one more reason to make sure that you give accurate information.
Warning to potential buyers: The .pdf manual is as worthless as this video. This guy should have done all of this off-line, then produced a video describing use, rather than all this fumbling.
11:40 You dont know how to use it :D
Why would you want to know the current or voltage of a USB charger
Why does your doctor use instruments?
Recommend you stick to evaluating devices you understand in the future. Sooo frustrating watching a clueless fop. The device has a great variety of measurements, unfortunately you could not even recognize when it displayed them. Duhh.
Please shave your fingers before making videos, thats savage!
The incompetence here is painful to watch . . . RTFM!!!!
You don't know what you're doing
