Overview
The FNIRSI C1 BT is a specialized USB-C power meter designed for the modern electronics ecosystem. Unlike bulky testers that rely on USB-A adapters, the C1 features a “straight-through” Type-C design that minimizes signal loss and interference. With its vibrant 1.3-inch color LCD and integrated Bluetooth, you can monitor real-time charging curves, trigger high-voltage PD profiles, and identify the quality of your cables directly from your smartphone or PC.
Key Features
Native Type-C Specialist: Designed specifically for USB-C to USB-C testing. No extra cables or adapters required to test modern PD devices.
Bluetooth Connectivity: Wirelessly sync with the Android App or PC software for real-time graphing, data logging, and long-term capacity testing.
PD Protocol Master: Advanced triggering for PD 2.0/3.0, PPS, QC 2.0/3.0, FCP, and SCP.
6-Digit Accuracy: Uses a dedicated 16-bit ADC chip to deliver incredible resolution ($0.00001$ for voltage and current).
E-Marker Reader: Instantly check if your USB-C cable has an E-marker chip and see its rated wattage ($60W$ vs $100W/240W$).
Independent Power Supply: Includes a Micro-USB HID port to power the tester independently, allowing you to measure from $0V$ without the device shutting down.
