Fnirsi FNB58 Voltage Tester
The Fnirsi FNB58 BT voltage and current tester is the ideal and compact solution for technology enthusiasts and service technicians who want full control
and advanced diagnostics of the charging process. Equipped with a generous 2-inch LCD screen with a remarkable resolution of 0.0001, this device
instantly detects the smallest fluctuations in voltage, current, or power and analyzes charger quality by measuring mains ripple.
The gadget offers extended universal compatibility, supporting the latest fast charging protocols such as Power Delivery 3.1
up to 28V, PPS, Quick Charge, SuperVOOC, or Dash, and has the ability to read data from E-Marker chips of cables up to 240W
to measure their internal resistance. With stable Bluetooth connectivity allowing data monitoring
through dedicated apps and smart functions such as offline recording of charging graphs for up to 9
hours or battery capacity calculation, this robust tester with 24-pin copper contacts
becomes a complete diagnostic center to prevent damage to your equipment.
