Also, it can monitor the voltage, current, power, resistance, capacity, temperature, D+/D- voltage, etc, and test the fast charging protocol of chargers. FNIRSI FNB48S Voltmeter Ammeter Current Quick charging tester protocol PD trigger Ammeter USB Tester QC4 PD3.

Then I repeated from scratch over and over again (same good certified cables), every time the sequence getting tester work was different.

This is an example of a camera charging from a PD source – to get this to work requires two USB-C cables and reversing one in case no negotiation is seen. The device claims the ability to monitor 4-28V, 0-7A, 0-120W and can integrate capacity/consumption. Wide Measurement Range: Capable of monitoring between 4-28V, 0-7A, and 0-120W, catering to a diverse range of USB devices. International products have separate terms, are sold from abroad and may differ from local products, including fit, age ratings, and language of product, labeling or instructions. High Precision: Boasts an impressive resolution of 10uV/uA/uW, ensuring accurate readings every time.

Volle Kaufempfehlung, zumal vergleichbare und ebenfalls genau anzeigende Tester mit ähnlichem Funktionsumfang teils weit über 100,- EUR kosten - aber bei kleinerem Display. Premier Farnell Ltd, registered in England and Wales (no 00876412), registered office: Farnell House, Forge Lane, Leeds LS12 2NE. With this device you can measure the power supply or power consumption of products or the charging power of cell phones and power supplies.

The main downside is the lack of good documentation about the recording file formats and the device interfaces, relying on reverse-engineered code to allow for more effective use in automation. It is a high-reliability, high-safety USB voltage, and current detection meter and a mobile communication terminal fast charging trigger. By pure coincidence, an element14 member by the name of scottiebabe posted a thread about the Fnirsi FNB58 USB Fast Charge Tester showing some rather good accuracy figures. Read more about the condition New: A brand-new, unused, unopened and undamaged item in original retail packaging (where packaging is applicable).

Using the PD Listener tool, we can “sit in” on a USB-C PD negotiation and see what is actually happening.
