Product Information

This suggests to me an ADC effective bit count of about 11- to 12-bits with oversampling used to create higher accuracy. Wide Measurement Range: Capable of monitoring between 4-28V, 0-7A, and 0-120W, catering to a diverse range of USB devices. 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.

Comprehensive Monitoring: Seamlessly measure voltage, current, and other vital parameters of USB chargers and cables. The top right shows the result from a USB-microB connection to an office desk integrated USB-A charge port which claims to support Samsung AFC as well but of course, none of the PD protocols. The FNB58 USB tester (with Bluetooth) is a comprehensive and very accurate USB voltage and current meter.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.

The cfn log files generated by the USBMeter companion app can be converted by a python utility writtenby didim99 https://github.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. You can change your choices at any time by visiting Cookie preferences, as described in the Cookie notice. I guess this is part of their “Power IQ” technology which means that both legacy and PD protocols are supported on the same port. When the PC port is connected, the device appears to enumerate as a USB-serial device, a USB mass storage device and a USB input device (HID class).

For many years, I have tested USB power consumption using lab-bench power supplies and electronic loads. Then I repeated from scratch over and over again (same good certified cables), every time the sequence getting tester work was different. Human-computer interaction, cell phone like intelligent operation, simple display interface; independent function menu; humanized operation. Bluetooth APP and upper computer, driver-free installation, synchronized data, efficient and convenient; Bluetooth APP over-voltage and over-current alarm.And how do I determine the orientation of every one of my USB-C cables, since many of them have no labelling on either end (so no "up" or "down").

These two cables are a little different – Vendor 0x2E87, Hardware 0x0000, Firmware 0x0000 is a Toocki 1m 100W cable which claims to be 2-3m.

inch LCD high-definition display, measurement data clearly visible; with 5P high-current USB-A, 24P full-pin Type-C input and output interface, charging detection, a step faster. The FNB58 USB tester is a high-reliability, high-safety USB voltage, and current detection meter and a mobile communication terminal fast charging trigger. 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.
