Description: Simultaneous display of voltage, current, and mAH data for easy viewing. Can detect mobile power output mAH. Multiple test data storage, power-down save function. Does not affect data transmission. More accurate, current parameters will not jump. USB male and Micro USB ports take power twice to detect the quality of MicroUSB cable. Current sampling 25 milliohms, less loss. With precision current calibration, higher current accuracy. Specification: Support voltage: High voltage version 3V-15V Support QC2.0 fast charge technology. Voltage resolution: 0.01V. Test current: 0.05A-3.50A. Current resolution: 0.01A. Capacity range: 0-19999mAH. Accuracy: plus or minus 1%. Line loss: about 0.1 ohms. Test content: battery voltage, current, and discharge capacity (a total of 10 sets of data). Package Includes: 1x USB Digital Power Tester
