    I appreciate some clear comparison of these USB testers, in addition to your other comparison video. Saved me a lot of time trying to figure out what did and didn't support older USB A\2.0 tests. The AVhzy C4 looked cutting edge with EPR etc. but had no easily apparent old USB testing support which I needed.

    Heads up, when the PD Com switch is in the ON position, VBUS on USB A (IN and OUT) and USB C (IN and OUT) are all connected together. For instance in listening mode your laptop charger negotiated 20V, the type A connector at that instant was also being back fed by the same voltage. I also have the same Anker battery bank and I tried the same test you did and the Anker battery bank survived the test. We got lucky that the USB A on the Anker device has a high over voltage protection threshold. For listening mode power the FNB58 from the USB micro labeled “PC” instead, that bus is isolated from the main VBUS.
    Also I notice that in listening mode or trigger mode sometimes the FNB58 wasn’t finding my device or charger. Turns out that the for these tests the cable orientation matters, at least for the cables I was using. If you are having trouble connecting in these modes try disconnecting the type C mainly at the FNB58 and rotating it 180 degrees. I haven’t really researched this, I will later, but I think it has to do with the CC lines being only located on one side.

    • @ElectronicsComputers
      @ElectronicsComputers  Před 7 měsíci +1

      Yes, you're right, you should only use the PC port for PD listening feature. But all good-quality power supplies typically have protection mechanisms in place to prevent voltage from flowing back into the supply when connected in parallel or from causing any damage due to reverse voltage. This is somewhat analogous to the concept of a diode, which allows current to flow in one direction but not the other.

      @@ElectronicsComputers yea i agree, I won’t worry about a bench supply or a wall adaptor. But since USB A is an output only port a PC maker may only have a current limit IC inline with the 5V buck with an absolute maximum rating of 6V. If that’s the case applying more 6V on VBUS will definitely blow up the IC.

    Great video! What sort of functions can be used to test the quality of cables and usb wall plugs? For cables i would assume testing resistance would be best and maybe looking at ripples in the output of wall plugs. I generally never use quick charge and try to use the lowest output wall plugs to not degrade the battery on my samsung galaxy devices.

    • @ElectronicsComputers
      @ElectronicsComputers  Před 7 měsíci

      For your Galaxy devices, simply go to the battery settings and turn off quick charge. Your phone or tablet will then charge using only 5 volts instead of 9 volts. As for USB wall plugs, you can check the quality of the supplied voltage using a scope feature. If you have a load resistor, you can verify if the claimed charging current can indeed be drawn from the charger. When it comes to cables, you can check the resistance, but I've never encountered cables so poor that the difference between an expensive one and a generic one is noticeable.

    If you already have a PSU connected to the USB-C IN port, do you still need to connect the FNB58 to the built-in USB-A (male) port to a power source (in your case, it's a USB-A power bank)? Just wondering if I need to always power the FNB58 using that USB-A connector even though I'll be testing only USB-C PSUs/devices.
    Wondering because this seems to be the most versatile tester (also very nice interface), but if it needs to be powered by the USB-A male connector to test USB-C power sources, that's unwieldy and inconvenient.
    For now, I want to test the Baseus CCZX-100CO car charger I just purchased (let me know if you have any opinions on this charger as well) but I'd have to do it in my car.
    Here's a video I did just as a preliminary test to see it's capabilities between my Pixel 7 Pro and a laptop that can draw 65W.
    czcams.com/video/mogYzbiRtBo/video.html
    But I want to verify ALL of the protocols it claims to support. I'm a bit suspicious of a small car charger that claims to do 100W. Even if it does, I'm afraid of the heat it will generate.

      No, you don't need to use a second power source. There's only one feature that requires a second power source, which is PD listener, and it should be that way. Baseus makes pretty good stuff, but I always recommend using Anker chargers if you can't buy an original one.

      Some devices will work flawlessly, while others may fail. It depends on the charge controller. I wouldn't force any device to accept a higher voltage, even if it's one of the supported ones. All USB ports provide 5 volts initially, and only after establishing negotiation between the power supply/charger and the receiving device, then voltage change to 9, 12, 18, or 20 volts.

      That would be great if such a USB tester existed, but unfortunately, it's nearly impossible to create one because there's no communication about the battery state between the charger and the battery. In theory, if you charge a completely drained battery, you can set a limit on the milliampere-hours (mAh) that the charger can pump into your device to charge the battery and stop charging at 80% capacity. However, if your battery, for example, has 20% charge remaining, it will still be charged to 100% with the same limit, and so on.

The options are expensive for me to act on the "trial-error" scheme... I want a device with which I can test chargers, cables and power banks. I'm not too interested in graphs/curves, I want to be able to check also what protocols are supported by the tested devices (automatic check is better) by 2024. I only have basic knowledge of electrical and electronics, so "deep digging" and statistics are not my priority, as well as dangerous tests. At the moment I have ATORCH UD24 and J7-c - I guess they are not too bad but they are old, maybe not very accurate - not very up to date as of 2024. Thanks in advance to whoever gave advice.

      Thank you for the comment! Well, the ATORCH UD24 that you currently have is a pretty good option that covers most needs. However, the best USB tester as of today is still the Fnirsi-FNB58. It is the most feature-rich device, allowing you to trigger all power delivery and charging protocols individually and in automatic scan mode. You can also check the resistance of USB cables to identify the most efficient and high-quality ones. Additionally, it can read the specs of the chip in the cable (if it has one).
      The scope feature is also beneficial, showing how "refined" the voltage coming from the charger is. Some cheap Chinese chargers have terrible filtering, which is not good for charge controllers in phones, tablets, and other devices. This tester has a very user-friendly interface. I use it almost daily and have never had any problems with it. Moreover, Fnirsi regularly posts firmware updates for their equipment, which is something other brands usually do not do.

    I just bought this tester and wanted to test a "26800mah" power bank I bought from Amazon. I don't quite understand how to read the results that's right in front of me. Lol. Is it a 9900mAh or 19600mAH capacity?
    Screen says the following:
    Battery CAP Calculation
    Group: 01
    Time: 0 days 14:36:41
    CAP: 9.92364 Ah
    NRG: 80.5495 Wh
    BAT Vol: 3.7V
    Conv Eff: 90%
    Results: 19.5931 Ah
    Thanks!

      The battery capacity is about 19600mAh. If you performed this test with fully discharged power bank, then that result should be very close to the real capacity not advertised one.

    They should upgrade the micro USB port to a USB c port for firmware updates, micro USB ports and similar, are extremely annoying.

      You don't need to use the micro port. Just hold the button/wheel before plugging in a type C cable, and it works the same way. That's how I upgraded mine.

    i dont think the cable spec check is useful. its surely not testing it in real time, its just reading whats in the EPROM probably, which could just be manipulated.
    so you will know at least your cable went thru extra step, whether it is indeed that spec, without a real load and real testing, it is just as useless i think.

    • @ElectronicsComputers
      @ElectronicsComputers  Před 6 měsíci +1

      Unfortunately, there's no tester that can determine the real specs of cables. Yes, the device can measure the resistance of the cable, but without knowing the cable length or wire diameter, you can't calculate the power it can hold. So you have to either enter those specs manually, or it will be just an estimated value based on cable resistance and the average wire gauge.

    The .pdf manual is essentially useless. The website is likewise pathetic. How do you upgrade firmware from linux? Even if I used Windows, no way would I install software from some unknown CCP company. A tutorial that walks us through using it for usb port capabilities detection, then to other features would be useful.
