Would really appreciate more videos on this device, even doing the firmware update. Your style makes it much easier to understand. Thanks.
I have had one of these for a while, and have YET to fully use all the great features! It is SO useful device in an easy to use device!
It really covers all the USB protocols and displays the quality of the power supply with the o'scope!
Thank you for the detailed review of this device!
i use fans on the PD mode (other brand) but to acces the high voltage part you had to disconnect and select the device countlessly clicking to the desired voltage :P this seems so easy !!
PE+ means "Pump Express". And you should do an update to your device. Then it can detect QC 4+, too.
With the Cable Resistance Detection I sorted out about 30 shitty USB cables and only keep the good ones. Most of the cables delivered with a device are just garbage, but there were some positive surprises, too.
Am I right in thinking that the 'resistance' is the sum of the resistances on the GND and Vbus lines?
@@Brian_Of_Melbourne No, it's just the resisitance of the wires 5 volt and ground. On the bus lines floats almost no current.
Very clever device. Showing the available charge rates is a quite useful function. The scope function is interesting. The ripple from various devices has in the past created problems with some of my MCU projects. Another very helpful video. This device is listed on Amazon, but at twice the aliexpress pricing.
Woah, this is the coolest and most feature rich USB tester I've seen. Not only good for testing voltages but would be very handy for sorting out my USB cables too. Love your channel mate!
I have one of these units and use it for measuring down to 10uA currents at 3-5V in a ATTINY85 using sleep mode and it works great.
I really recommend FNB58
Have zero clue why i need this, i just subscribed because you killed it with the topdon 04. Now i want this thing. If you did a video on eggs and bacon i think i would get hungry lol
Excellent overview! Thank you!
Boy I would be lost without mine I have one that I bought last year almost. And it is very handy. And the company definitely supports their products!
Yes I want this. No I don't need this. If it had been under thirty quid I would have bought one.
yeah 40-50 is pushing it a bit
I have this beauty since a few months but never really used it because I was not sure what stuff I can do with it besides measuring power flowing through it. But this could be also done by my older power meters. Now I know what I can do with it. Thanks Julian.
It's the best review of that tool in RUclips.
Thank you for your very informative review.
😊
Glad it was helpful!
What a cool product. Just ordered one. Would love to see a video showing the PC and smartphone features, including how to update Firmware.
This is a very comprehesive device. Nicely done, easy to read display.
Interesting as I had one of these delivered today! Trying to decipher the manual is interesting.
Beautiful. Thanks Julian.
Super test, thanks a lot for test and link to the shop.
Thanks for the awesome video. This is a very interesting tester. I love getting a no nonsense insight into cheap test equipment.
Would you be interested in doing a video on one of the "elejoy" branded PV panel testers that are all over aliexpress? I haven't yet found a good video on them and they look very interesting to me.
Great overview, thank you! And you know pretty much about USB as well.
That red powerbank looks like one I have, where you insert your own. 18650, or in my case 21700s.
Is it just me, or is the percentage calculation really unreliable?
It drops very quickly on an initial load, but lasts a lonnngggg time at the lower percentage readings.
Great device, just got one. That white power bank looks like it's got a bad filter capacitor in its circuit. I wouldn't use it. Shows you the kind of useful information you can get from this device!
This channel deserves 1M subs. Greetings from 💙💛💙💛 SWEDEN 💙💛💙💛
all i was interested in was the battery capacity guage and cable resistance. I got 50% of results. thanks
lost my old one ,,, somehow... but this seems so much better !!
Cracking little device. No idea why I want one but its ordered :)
So how was the software and the BT?
Cool gadget. Too bad the voltage rating is only 28v. The current PD standard allows up to 48v for 200 watt power.
perhaps the device can work out the cable length if we plug the cable into both type C ports of the device
Have you compared it to a accurate 6 1/2 dmm?
I would suspect that they could've settled for 2 or 3 decimals. I can't imagine the last digits are really that accurate, and who would need such data when checking cables/devices anyway?
BTW how would you measure cable resistance of a USB-C USB-C cable? Or USB-A USB-A? Not possible without some adapter, right? (which has an unknown resistance of its own)
The latest firmware version v0.68 removed the "USB-C E-Marker" function from the toolbox, So I had to roll back to v0.67. I've contacted Fnirsi but they've not fixed it yet.
I found the information when I had a USB C to C cable plugged in under USB-C Cable in toolbox, on v0.68. I think they just integrated the e-marker functionality into the USB-C cable test functionality.
@@alexa5231I tried updating it to v0.68 again and had a look in the "USB-C Cable" menu and sure enough the info is on the second screen after pressing the jog wheel. Not as obvious as before, but thanks for making me aware of it.
Hi, I tried to upgrade to v068 but I couldn't find how to put the device in bootloader mode, any hint please on how to to that? in the manual, the instructions only say to select the file and upgrade it !!!
@@cyrixone2771 To update it, you need a decent USB data cable. Press and hold in the toggle button, then plug the USB cable into a computer. This should then make the FN58 show up as a USB drive in your computer. Place the update file in the drive and it should update.
Hold the Jog wheel down while plugging in the micro usb cable@@cyrixone2771
Cool gadget
Does this test all data wires in the cables?
Have you had the chance to compare it to Power-Z meters?
What this device have more than other USB devices for mesuring current? I had two of this devices and i think they are total garbage because these devices limits the current that flow through the cable compared without this device.These devices have their own resistance and therefore distort the measurements.
A very handy gadget. I need to add one to my wish list.
Had one for quite some time now, it got rid of so much bad cables ... 😃
Hola porfavor necesito que alguien me explique que fallas detecta este usb!!! Si el movil por ejemplo carga correctamente aunque este apagado que significa ? O si no enciwnde ni hace nadq y carga normal que puede see ?
What, no teardown?
I have this one and am completely disappointed. Living in 2024 you would expect such a unit to support USB 3.0. It doesn't. No data is going through, so it is impossible to test USB3 buspowered devices, as without data they simply don't start up.
Very good "Executive Summary", could you please make a video of how to do the firmware upgrade?
14:00 PD 100W? That's BS. It can do only 20V 3A. Or maybe it's a cable issue: you need a cable with an Id chip to tell the PD system that the cable will handle 5A without melting.
And high-current cable is exacly one, that is used at this case. 18:13 - should be reading for it's e-marker.
@@volodumurkalunyak4651watch carefully, the cable used to test the power bank is not the 5A one tested later...
This is an expensive device. Not so much the rather hefty price in itself, but for all new cables I will have to buy after checking my current ones
I'm pretty certain most cables that came with devices are rubbish😊
i have the 48 version
USB-C, when charging gets difficult and a cpmplete mess of different specs and cables.......
Great video, I love that tool, it will help vet the good from the bad.
why does it say 'SUMSUNG'??
Fixed in later firmware
Heh, even on ali, 40 Eww Ess Dollahs. There aren't enough ways it can give me pleasure to justify that much when I can, for my own pedestrian needs, just plug a cheaper USB current meter in and see how something is charging. If my widget charges fast enough for my needs, purpose met.
have all the stuff you have.. dammit .. its like gambling... but worse :P
Yeah your firmware is out of date grandad, you live under a rock dude ? Julian be like 'I aint rocking down with the the kids Bruh'....cheers.
Hey there is nothing wrong with living under a rock, Cheese!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Squeak!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!@@fredflintstone1
I dream of living under a rock. I have to make do with a small patch of gravel.
@@JulianIlett Poor Andy has to do with a damp cardboard box 🙂
Your firmware is old 0.63
0.68 is most resent. 🙂
