Function: Built-in US -A interface, Micro-USB, Type-C interface, using external 16-bit PD protocol physical chip. Real-time monitoring of charging voltage, current, power, capacity, charging protocol, curved waveform, etc. High precision: five-bit or six-bit display can be switched by a single button, with the maximum resolution of 0.0001. High speed: USB 3.0 interface, 9-pin design, backward compatible with USB 2.0, transmission rate 10 times that of USB 2.0. < p>Data logging: This product can save 10 sets of measurement data, you can use the data you get to calculate the battery capacity, fast and convenient. Easy to use and operate. High-precision 6 display: 5-digit/6-digit display one-key switching, maximum resolution of 0.00001, real-time monitoring of subtle voltage changes , current and power while charging, and also can detect low current when the original Apple data cable is empty. The interface is newly upgraded and the rate of transmission is doubled: FNB48 uses USB3.0 interface, 9-pin design, backward compatible with USB2.0, ten times the transmission rate of USB2.0. No need to have the original data cable provided, you can also directly detect the charger protocol of OPPO, Huawei, OnePlus and other brands. Multiple sets of charging capacity calculation data logging battery: FNB48 can save up to 10 sets of measurement data and can use the measured data for battery capacity calculation. Gravity sensing screen automatic flip: FNB48 has improved the screen flip function, through the gravity induction method, the screen can be flipped freely; it can also disable gravity direction recognition, and the screen can be flipped in time-lapse for a long time. the middle button. FNB48 directly puts the battery capacity calculation formula on the tester, and the calculation result can be multiplied by 1000 to get the battery capacity, which is more convenient and quick to calculate. Cable internal resistance detection: FNB48 uses the differential pressure method to measure the internal resistance of the cable, and is used with a constant current load to easily detect the internal resistance of the cable.
