    Thanks for your video! I tried it with my electronic load and discovered that it works only with 1 A load current, not with 2A. The current measurement of the FNB58 is precise up to 4 digits!

    Thanks for the great review!
    Can the FNIRSI FNB58 use, identify and test Thunderbolt 3 and Thunderbolt 4 cables?
    Thank you!

      No, it is strictly USB tester only, sorry. I searched Amazon for tester for your cables, but there isn't any tester for your needs. But in very short time, the apple products will have USB-C ports, so you will be able to buy a tester or two like the rest of the world! Personally I think there should be one cable and one charger for customers, so there is less waste and makes the devices compatible, again it is great for customers!
      Have you seen my other video that also test USB cables? ruclips.net/video/4jeWTULCkYA/видео.html&ab_channel=TonyFleming
      I searched for an a adapter for your cables, but couldn't find any that I can recommend.

    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!

      Good question. I do not know the answer. I tried to recreate what you did, but I'm not getting the same results you have.

    Kann der FNB58 mit aktueller Firmware nur 120 Watt? In den Spezifikationen steht maximal 120 Watt! Das schwächste PD3.1 Ladegerät kann 140 Watt! PD3.1 selbst geht bis 240 Watt.
