The other day I looked at a USB Meter $25 that’s perfect for those who want to check if the USB ports and devices like chargers and power banks are working properly. It’s a great tool for appliance repair enthusiasts.

But if you are more serious about diagnostics and repair, and have a slightly larger budget, then you should get a complete USB multimeter packed with all kinds of features, from data logging to determine if your cable is suitable. Support high power charging.
This tool is Fnirsi FNB58 . USB Tester.

But this simplicity holds a lot of power, and I suggest download and get acquainted really with the user guide, because the utility is full of stuff and it’s easy to find yourself faced with some seemingly intimidating warnings.

One feature of the FNB58 that I really like is the real-time voltage and current waveform display which gives me a quick idea of what the meter is sensing, which can dramatically speed up diagnostics. tell. For intermittent faults, the meter can record waveform data for up to 9 hours.

Another useful feature is readability Electronic marking chip data found in higher quality USB-C cables. This chip allows the cable to communicate with the devices it connects to, providing information about the cable’s capabilities, power capacity, and supported features.

The Fnirsi FNB58 is a powerful, versatile and affordable USB test meter for just over $50. Not only does it give you information about typical volt/amperes power, but it can also view this information as a waveform and even log data for hours. It can read E-mark and DASH cable data, perform cable resistance tests (this can detect internal cable damage that would otherwise be invisible), display charging protocol which is being used, etc.

It’s an exhaustive list of features and is far from complete.
The display is one of the best I’ve seen on a USB watch, and the user interface is simple. But this watch is much more than that and I recommend reading it over and over, then re-reading the user manual and spending time testing the watch to get familiar with what it can do and what to expect. wait from it.
If you want a cheap meter, KJ-KayJI . 2-in-1 USB tester is a good option, under $25, but if you want more functionality and capabilities, Fnirsi FNB58 is a big step forward for less than double the amount.
