Would really appreciate more videos on this device, even doing the firmware update. Your style makes it much easier to understand. Thanks.

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.

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 !!

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

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.

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!

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!

Excellent overview! Thank you!

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.

This is a very comprehesive device. Nicely done, easy to read display.

Super test, thanks a lot for test and link to the shop.

What a cool product. Just ordered one. Would love to see a video showing the PC and smartphone features, including how to update Firmware.

Interesting as I had one of these delivered today! Trying to decipher the manual is interesting.

Great overview, thank you! And you know pretty much about USB as well.

Beautiful. Thanks Julian.

Yes I want this. No I don't need this. If it had been under thirty quid I would have bought one.

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 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 💙💛💙💛

lost my old one ,,, somehow... but this seems so much better !!

all i was interested in was the battery capacity guage and cable resistance. I got 50% of results. thanks

Cracking little device. No idea why I want one but its ordered :)

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.

Cool gadget. Too bad the voltage rating is only 28v. The current PD standard allows up to 48v for 200 watt power.

Cool gadget

Had one for quite some time now, it got rid of so much bad cables ... 😃

A very handy gadget. I need to add one to my wish list.

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?

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.

@@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.

perhaps the device can work out the cable length if we plug the cable into both type C ports of the device

So how was the software and the BT?

With the current aliexpress sale, I might be able to get enough credits to get this model completely free.

Have you had the chance to compare it to Power-Z meters?

Great video, I love that tool, it will help vet the good from the bad.

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)

@RationallySkeptical

Incorrect. It has return ports on the opposite side for all the major usb connector types. It CAN do this.

Does this test all data wires in the cables?

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😊

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.

i have the 48 version

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.

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 ?

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.

How do you know? The power bank he used wasn't even shown on-screen. The Anker 737, for example, has no problem at all putting out circa 140W, so 100W certainly is attainable. What exactly are you objecting to?

USB-C, when charging gets difficult and a cpmplete mess of different specs and cables.......
