Description
xCrystal-clear data at a glance
Meet FNIRSI FNB58, a compact USB tester that combines a bright 2.0-inch TFT LCD display with a versatile interface set. It delivers real-time readings for voltage, current, power, resistance, and more, so you can understand how a charger, bank, or adapter behaves in everyday use. The integrated USB-A, Micro-USB, and Type-C interfaces help you test across a range of devices, while the precise readouts are designed for quick checks and informed decisions in the moment.
- Integrated ports streamline measurement across devices
- Real-time readouts for voltage, current, power, and resistance
- Onboard temperature sensing adds context during testing
Comprehensive fast-charge protocol detection
Go beyond basic measurements with protocol detection that covers popular fast-charging ecosystems. The FNB58 can monitor activity across several standards, helping you identify compatibility and behavior without guesswork.
- Supports QC 2.0/3.0, PD 2.0/3.0, AFC, FCP/SCP, VOOC/WARP, and more
- Automatic monitoring and MTK-PE detection for effortless setup
- Protocol conversion QC2.0 to PD2.0 for cross-checking convenience
Precise data logging and waveform analysis
The tester is designed for longer sessions and precise analysis, offering a clear six-digit display and flexible storage options. It also provides high-speed ripple and waveform tracing to visualize power quality in real time.
