ITEM NAME:Multifunction USB Tester Digital Voltmeter Ammeter Voltage Current Detector Product Description Description: Features: It can conveniently measure the output voltage of the USB port and the working current of the device; 2. It is compact and needs no power supply and other ancillary equipment, plug and play; it can also detect whether the output voltage and current of the USB charger meet the standard; it is suitable for factories, laboratories and users. This electric energy tester adopts a new generation of 4-bit semi-dual integrated circuit with precise bandgap reference source. It has accurate measurement range, high accuracy, stable operation, reliable performance, strong anti-interference ability and high temperature resistance. It can be used to measure the power supply or power consumption of USB interface, mobile phone charger, U disk and other products. This product can measure the voltage when the USB power supply equipment is empty or loaded, and the voltage and current when the USB terminal equipment is working. The current and voltage cycle display is simple, convenient and practical. Specifications: Technical Indicators: Scope of Work: Current (0-2.5A) Detection of Cell Phone Charger Voltage to meet DC5V Standard Scope of work: U = 3-7.5V I = 0-2.5A Resolution: Voltage 10 mV Current 10 mA Error: Voltage
