About this item
  • FASTER TRANSMISSION RATE WITH USB 3.0: FNB48 uses USB3.0 interface, 9-pin pin design, compatible with USB2.0, transmission rate is 10 times that of USB2.0, and more energy-saving.
  • HIGH PRECISION DISPLAY: 5-digit/6-digit display with one-key switching, max resolution 0.00001, real-time monitoring of subtle changes involtage, current and power during charging. Weak current can also be detected when the original Apple data cable is no-load.
  • MORE DATA LOAD: FNB48 can record up to 10 sets of measurement data. It could directly put the calculation formula of battery capacity on the tester, The calculation result is multiplied by 1000 to get the capacity of the battery, and the calculation is more convenient and faster.
  • PD E-MARKER, DASH CABLE INSPECTION: FNB48 supports reading the data of E-Marker and DASH cables. After connecting the data cable, it is easy to read the chips of E-Marker and DASH cables. With analog DASH cable and Apple 2.4A acceleration function, it can directly charge and detect voltage and current without the original data cable.
  • GRAVITY SENSING: The screen OF FNB48 can be flipped freely trough gravity sensing. Also the gravity direction recognition can be turned off, long press the middle button can realize the screen flip.

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.
