FNIRSI® FNB58 USB Fast Charge Tester

Avendo acquistato 2 prodotti della FNIRSI un modulo HT-P1B e un FNB58 devo dire che entrambi funzionano molto bene e sono di facile utilizzo. La FNIRSI è una azienda seria con prodotti validi e precisi a prezzi accessibili

Very good quality, a professional in his field.

The user manual leaves a lot to be desired, and does not make it clear what real-life uses the FNB58 has. Here are some of the most useful features I've found from my testing.

• Read USB-C Cable E-Marker Chips: Higher-end USB-C cables have an embedded IC chip that reports capabilities of the cable to the PD power source. This allows the power source to provide higher voltage and wattage through the cable for higher-powered devices, up to the limits of the cable. If there is no chip in the cable, your expensive new USB power adapter will only be able to supply up to 60W of power instead of the 240W you paid for! The “Toolbox” option “USB-C Cable” quickly and easily reads this chip, if present, so you'll know what that cable supports.

• Read Charger Protocol Capabilities: Use the “Fast Charge” menu and pick "Automatic Detection" to test for USB charger capabilities, like PD, Apple, Battery Charging (BC), Samsung, Huawei, or QC (Qualcomm) fast-charge protocols.

• Fast Charge Triggering: Higher-voltage power protocols from the above can then be triggered, changing the output voltage and current settings on the USB power wires. Some of the protocols (like the PD or QC 3.0) have variable voltage adjustments, so you can set the output voltage to anything between the protocol limits (like 3.3V-20V) in 0.02V increments. You can thus even use the FNB58 and an appropriate charger as a variable power supply for small low-power projects!

TEST RESULTS AND IMAGES

The "USB-C Cable" screen photo here shows the results of testing a USB Type-C cable that DOES have an E-Marker Chip embedded in the cable's connector. Plug the Type-C cable to be tested into either the Type-C “IN” or “OUT” port. Only one end of the cable needs to be plugged in for this test. Use the rocker switch on top to navigate to the Application page. Select the Toolbox option, then select “USB-C Cable” (or “USB-C E-Marker” on earlier firmware).
This will display the values embedded in the cable’s E-Marker chip, which provides the USB power source with the capabilities of the cable like cable speed (example: “USB 3.2 Gen2”), cable length specification, max cable voltage and current, hardware and firmware levels, and cable vendor ID. If the cable can handle it, the power source may select higher voltage and power for higher-powered devices. Without this chip and the resulting negotiation with the power source, output is limited to 60W (some USB power sources have the option of providing up to 240W).

The image here with three screen-shots shows the different capabilities between ports on the same charger. Chargers often support different USB power protocols and protocol values, depending on the port being used. For example, this photo shows three USB-C ports (C1 – C3, top to bottom) on the same charger, each with a different set of protocols and supported voltage/power values. Note the discrepancy between the label on the charger (last photo) and the values being read by the tester. When triggering the protocols (see below), what I was able to get out of the charger were the voltages listed on the tester, not always what was printed on the back of the charger. Some of the values are limited because of the standard for the protocol, like the BC 1.2 (DCP), which limits the output to 5V at 1.5A. But the labeling on the charger can mislead you about what output you’ll actually be able get from it! The FNB58 "Fast Charge" option's "Automatic Detection" feature displays the power source's supported protocols, and their voltage limits for each USB port. This also helps clear up some discrepancies between the charger's specs and the actual port output.

The image with the multi-meter at the top shows the results of one of my power source output tests. Once the available fast-charge protocols have been detected (like above), you can "trigger" any of the protocols with the FNB58, to set a specific output voltage. I did physically test the output of the charger after triggering the protocol, to verify the charger actually did change output voltage. My multi-meter tests correlated closely to the output voltages shown on the tester after triggering the protocol settings. The voltage manually selected in the tester is shown outlined on the left of the tester’s screen (10.00V here). The actual voltage as measured by the tester is shown with the green background on the screen in the upper right (10.239V here). The external voltage measured by the multi-meter here is fairly close, at 10.28V. Each protocol has different voltage selection options. To test these, navigate to the Application page of the FNB58, select the Fast Charge option, then the PD Trigger option.

I summarized much of what I learned and tested, and put it in a rudimentary task-based guide. My "FNIRSI FNB58 User Guide" PDF document is on my Google Drive at:

Device doesn't have support for PC - but fear not, I made some, and it works pretty dang well over USB and Bluetooth! Enjoy and ping me on github with issues you encounter.

FNIRSI® FNB58 USB Fast Charge Tester

I think the product is good. I like it.
1. It would be better if they sold or planned to sell a dedicated constant current load device.
Other companies sell dedicated constant current load devices, but if they don't sell the product, you will have to use a product like the HD35. It is still possible to measure, but the resistance of the cable is very small, so I doubt the reliability of the measurement results.
2. This time I paid by credit card, but the card company put the payment on hold. → It has now been restored.
3. When I download and install the software, it is displayed as "harmful software."
If this can be improved, I would give it 5 stars.
製品は良いと思います。気に入りました。
1．専用の定電流負荷装置を発売している、あるいは発売する予定があればもっと良いと思いました。
他社では専用の定電流負荷装置を発売している所もありますが、製品の販売がない場合HD35のような製品を使う事になります。それでも測定は可能ですが、ケーブルの抵抗値が微少なので、測定結果の信憑性に疑問です。
2．今回はカード決済で購入しましたが、カード会社から決済を保留されてしまいました。→現在は復旧している。
3．ソフトもダウンロードしてインストールすると「害を与えるソフト」と表示されてしまいます。
このあたりが改善できれば★5つです。

A very useful device to monitor the current draw of USB powered items and also check the capabilities of power supplies, especially USB C. The instruction booklet is not overly helpful, but the unit’s operation is fairly straight forward. I’ve not tried the computer link as yet (does it link happily to a Mac OS?) but seems good value overall so would recommend to others.

Unfortunately there was a problem at my local customs department. They refused to accept the customs declaration and tried to charge me extra fees. Thererfore I had to reject the package. The FNIRSI support team was very dedicated and helpful in this case. Even though the delivery did not work out, they were always friendly and courteous and even offered compensation, which I kindly declined. I have now had the chance to acquire the product through another means and am very satisfied with it. Therefore, despite the circumstances, 5 stars for the support and the product.

I have just received the FNB58.
The installed FW is 3 version old. To update it I need the USB App. Now, I have been searching for 2 hours, but I cannot find this app. I'll spend some more time searching, and if I cannot find it I'll send it back. I'll change my review if I fix this issue
UPDATE: PC App and FW installed
1) browse fnirisi.com + Download + Firmware + scroll down to the USB Tester section
2) click to FNB58_V0.68.zip + extract the directory
3) from the USB Tester, download also the USB_Tester_App_PC_Software.txt
4) open the file and copy the link with “PC Software”, and download the zip file, open it and extract the directory + run UsbMeter.exe. A small mostly black empty window appears in your screen.
5) keep the FNB58 powered off and disconnected. Press the wheel button on the device and keep it pressed while you connect the micro-USB marked as PC connection
6) at this point the App on your pc should show a populated window. Select the System tab (it is up on the left)
7) on the middle right there is Folder icon, click it and go to the dir where you saved the Firmware file. The box below should show that the file is valid
8) click the refresh icon on the bottom right. The firmware upgrade should start. Follow the progress on your device. My first attempt stopped at 6%, I disconnected/reconnected the cable and repeated the process. This time it worked
Fnirisi, better you put this explanation in the manual

Great quality and works great

Great little tester. I use it to check my power supply protocol (fast charging). The unit got here (CZ) in 10 days, which is very fast for a mail from China.

Works

Good store and seller, quality of item good ,well packaged and shipping was fast. I recommend the product and seller.very happy.Packaging was excellent.product smaller than what the picture actually display,but is ok

The product arrived very quickly (fnirsi fnb58 with Bluetooth), there was a problem with the device after the firmware to the new version, flashed and off when testing, (PD switch on and off, settings are all by default. Behaved the same way) reflash again, the problem did not go away.
Recorded a video of the problem, sent it to the seller. The seller immediately offered to send a new device, and pay only shipping, the price is 0,2 cents. (only in the order was the cable, not the device itself. In fact the device fnirsi fnb58 with Bluetooth arrived) agreed, I just tested the device that came just as quickly, everything works)))))

Thank you very much for your responsiveness to the seller! Big sales to you!
I advise the seller!
Very satisfied!!))

Good product. Do what we ask to do. English only instructions.

It's good if someone is in doubt whether to pay extra, do not hesitate. I asked the seller to download the latest firmware and he kindly did it to me, the tester came with the firmware 0.68.

The order came quickly, it works as it should😉
