About this deal

The first thing I chose to do was to update the firmware which requires holding a button during insertion to place the device into bootloader mode. Wide Measurement Range: Capable of monitoring between 4-28V, 0-7A, and 0-120W, catering to a diverse range of USB devices. The statistics page allows for reading the recorded energy integration statistics, clearing them, viewing offline recording records and making a simple battery capacity calculation based on nominal battery voltage and conversion efficiency. I tested with several USB-C cables (rated for PD 100W and over), using a PD 140W supply as a source. New: A brand-new, unused, unopened and undamaged item in original retail packaging (where packaging .

It can be used to measure the power supply or power consumption of products such as USB interfaces, mobile phone chargers, and U disks; measure the charging power of mobile phones and the input and output of mobile power supplies; test the fast charging protocol of chargers.

Using the PD Listener tool, we can “sit in” on a USB-C PD negotiation and see what is actually happening.This is probably not quite the protocol-decoder that some would have wished for in terms of being PC-connected, but it is serviceable for basic checks. PD E-MARKER CABLE DETECTION function makes it read data information of line with E-Marker chip, and DASH CABLE DETECTION function makes it read DASH cable chip related data, also support cable internal resistance measurement. FNIRSI FNB48S Features: FNIRSI FNB48S is an multifunction protocol capacity test tool, it integrated USB-A, Micro-USB, type-C interface, with 1. range, there is certainly a bug either in hardware or software that introduces a ton of noise into the readings. Real-time voltage and current curve for view recharging curve changes in real time Abnormal recharging is found immediately; 2.

Another useful feature is eMarker detection which allows us to examine whether a given USB-C to USB-C cable has an eMarker chip and if so, what capabilities it is advertising. Each one had an orientation where they would supply power to a device and, when flipped, wouldn't power a device (I checked with a Lenovo laptop, and a 100W PD battery that needed charging). Does the PC application show the communication packets on the CC lines, when a PD contract is messaged? Then you can connect to the device and then tap on the “enter” button to be able to view the device data.

The right is for a ZMI zPower Trio 65W and it actually supports 65W with 5 power profiles, but none of the legacy protocols. Likewise, these setups aren’t exactly convenient for a quick test, and while the Charger Doctor, USB Detector and Keweisi meters have been good enough for basic voltage and capacity checks, it is completely powerless to diagnose the quick charging protocol negotiation process.

While there is an oscilloscope-like display for ripple, it is somewhat frequency bandwidth limited and the vertical scaling is automatic which can result in unstable displays. Since we are now in a USB-C PD world, understanding the power profiles are similarly important to understand whether a given charger and device are optimal, especially given capabilities such as PPS. Acquired a FNIRSI FNB58 USB meter and made sure it was the BT version so I can connect via my phone. I think this makes it quite clear how useful it is to have around to see what a given port is capable of. High Precision: Boasts an impressive resolution of 10uV/uA/uW, ensuring accurate readings every time.

This tester allow for checking voltage and current, performing battery tests (to check for battery capacity), checking what charging protocols are supported by the charger (or battery pack) as well we checking the wattage raiting of a USB C cable. low resolution, real-time monitoring of the subtle changes in voltage, current and power during charging.
