FNB38 USB Tester - Voltage and Current Meter
The FNB38 USB Tester - Voltage and Current Meter allows you to check the performance of your wall, car, or solar chargers and USB charging cables. You can also use it to determine the maximum current of a wireless charger and test the capacity and electrical energy of a portable charger. It can also perform a wide variety of tests on devices such as desktop computers, laptops, desktop computers, mobile phones, portable chargers, chargers, discharge loads, car chargers, and cables.
Features
- The FNIRSI FNB48P USB tester features a 1.77-inch full-color ultra-wide viewing angle TFT LCD screen and integrated USB-A, Micro-USB, and Type-C interfaces. This device is highly reliable and safe for measuring USB voltage and current, and can also trigger fast charging on mobile communication terminals.
- The FNB48P uses an external 16-bit ADC and PD protocol physical chip. It can measure the power supply or power consumption of products such as USB interfaces, mobile phone chargers, and USB drives. This tester can monitor various parameters such as voltage, current, power, resistance, capacity, temperature, D+/D- voltage, etc. It can also test the fast charging protocol of chargers.
- The FNB48P supports trigger detection of various real-world charging protocols, including GC2.0/QC3.0, FCP/SCP, AFC, PD2.0/3.0, VOOC/WARP, and Super VOOC 1.0/2.0 triggers. All these protocols can be automatically monitored.
- Furthermore, this device provides a high-level six-digit display for voltage, current, and power. The highest resolution is 0.00001 (V/A/W).
