This device allows you to check the performance of your wall, car, or solar panel chargers, as well as USB charging cables. You can also use it to find out the maximum current of a wireless charger and test the capacity and electric energy of a power bank. It can also perform a wide range of tests on devices like PCs, laptops, desktop computers, mobile phones, power banks, chargers, discharge loads, car chargers, and cables.

Features of FNIRSI-FNB38 USB Voltmeter Ammeter USB Tester:

The FNIRSI FNB48P USB tester has a 1.77-inch full-color ultra-wide viewing angle TFT LCD display, integrated USB-A Micro-USB, and Type-C interface. This device is highly reliable and safe for measuring USB voltage and current, and it can also trigger fast charging on mobile communication terminals.

FNB48P uses an external 16-bit ADC, PD protocol physical chip. It can measure the power supply or power consumption of products such as USB interfaces, mobile phone chargers, and U disks. 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.

FNB48P supports trigger detection of various fact charging protocols, including GC2.0/QC3.0, FCP/SCP, AFC, PD2.0/3.0, VOOC/WARP, and supper VOOC 1.0/2.0 trigger. All of these protocols can be automatically monitored.

Additionally, this device offers the highest six-digit display of voltage, current, and power. The highest resolution is 0.00001 (V/A/W).
