Lcd Micro Usb Charger Battery Capacity Voltage Current Tester Meter Detector +Load Resistor 2A/1A With Switch Voltmeter Ammeter

Product features: 1. Simultaneously display voltage and current mAH data for easy viewing and detection of mobile power output mAH 2. Save multiple sets of detection data, and the power-off save function does not affect data transmission 3. With higher accuracy, the current parameters will not jump randomly, and the current sampling of 25 milliohms will result in smaller losses 4. With precise current calibration function, the current accuracy is higher 5. Safe charging, -time monitoring and mastering of your charging data Main parameters: Input voltage: 4-30V Voltage resolution: 0.01V Test current: 0-3A Current resolution: 0.01A Capacity range: 0-19999mAH Accuracy: plus or minus 1 Line loss: about 0.1 ohms Packaging list: Voltage Ammeter * 1 The merchant warrants that their products comply with all applicable laws, and are offered only if they comply with Joom's policies and EU Product Safety and Compliance laws.
