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 !!

@DavidUnderhill 3 місяці тому

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 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

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.

@Brian_Of_Melbourne 3 місяці тому

Am I right in thinking that the 'resistance' is the sum of the resistances on the GND and Vbus lines?

@kapegede 3 місяці тому

@@Brian_Of_Melbourne No, it's just the resisitance of the wires 5 volt and ground. On the bus lines floats almost no current.

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.

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.

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.

@alexa5231 3 місяці тому

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.

@@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.

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)

@universeisundernoobligatio3283 3 місяці тому

Have you compared it to a accurate 6 1/2 dmm?

@bennylloyd-willner9667 2 місяці тому

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?

@francisdoll1253 2 місяці тому

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.

@cmuller1441 3 місяці тому

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.

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.

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.
