Product Information

Legacy proprietary fast-charging protocols are numerous and considered a ripe pain-in-the-butt to understand why certain combinations of chargers, cables and devices just work and others are slow. 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. Plugging it into power and a load, the initial screen functions as a basic meter with a hold feature. We don’t share your credit card details with third-party sellers, and we don’t sell your information to others. FNB58 USB tester is a high-reliability, high-safety USB voltage andcurrent detection meter and a mobile communication terminal fast chargingtrigger.

FNB58 also has many functions, including the internal resistance measurement of the wire by the differential pressure method, E-Marker cable chip reading, DASH cable data reading, the record of startup time, onboard temperature measurement, PD monitor, etc. Being USB-C PD capable, it would fill a capability gap of mine, so I decided to splurge as a “gift to myself”.A small switch allows for the isolation of USB-C PD communications – this feels slightly fragile, but depending on how it is used, it may only be needed very rarely. charger into USB-C PD, reading USB-C eMarker chips, reading DASH cables and emulation of DASH cables and Apple 2.

To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. It can be used to measure the charging power of mobile phones and the input and output of mobile power supplies. Trigger modes below that are protocol-specific, but allow for manual selection and activation of various current/voltage profiles. 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. Does the PC application show the communication packets on the CC lines, when a PD contract is messaged?Premier Farnell Ltd, registered in England and Wales (no 00876412), registered office: Farnell House, Forge Lane, Leeds LS12 2NE. The cfn log files generated by the USBMeter companion app can be converted by a python utility writtenby didim99 https://github. It was listed as having bluetooth and the delivered version did have bluetooth which is what I wanted.
