Detect problems before they damage your equipment

Advanced power supply ripple measurement allows you to quickly assess the quality of your charger. The device clearly indicates the ripple level, allowing you to assess whether the power supply is excellent, normal, experiencing high ripple, or even poor quality. This helps you avoid using inferior chargers that shorten battery life and compromise device safety.

Real-time and offline curve analysis

The FNIRSI FNB58 BT displays live voltage and current waveforms, allowing for immediate detection of improper charging. It also offers offline curve recording for up to 9 hours, allowing for analysis of the entire process after charging. Monitoring the D+ and D- curves provides full insight into charging protocol changes in real time, making the tester an expert tool.

Cable and Actual Performance Diagnostics

The device can read data from the CC line in PD cables with an E-Marker chip, detect DASH cable parameters, and measure their internal resistance using a two-stage method under constant current load. This makes it easy to check whether the cable actually meets the declared parameters and is suitable for high-power fast charging.
