MECCANIXITY Dual USB Current Voltage Detector Meter USB Voltmeter Ammeter Red Blue LED Display for Computer USB, Home Chargers,USB Terminal Devices 1Pcs
What is this? This product can measure the voltage of USB power supply equipment when it is empty and loaded, and the voltage and current of USB terminal equipment when it is working. It is suitable for computer USB, home chargers, car chargers and other electronic products. What will I get? Input/output voltage:3V-9V Voltage resolution: 0.01V Input/output current:0-3A Current resolution: 0.01A Measurement precision:±1% Line resistance:about 0.1Ω Are there any advantages of the product? High stability;High precision;Display voltage and current data at the same time for easy viewing;It has a wide range of applications and can be used on any cellphone or any USB electronic product. It can detect a variety of power supply output voltages and currents;It can detect the quality of USB cables, and also detect the charging current and voltage of any USB device (computer USB, home chargers, car chargers) to determine whether the charger's performance meets the requirements;Compact and easy to carry, no need to connect to another power supply,just plug and play;With current calibration function. How to use it? Measure voltage and current: Plug the USB male plug into a charger, plug the female plug into a cellphone or other devices, and directly read the voltage and current parameters. What should I notice? It can only display the actual working voltage and current of electrical appliances, and does not have the function of a discharge meter, that is, it cannot set a certain voltage and a certain current to discharge.
