## Description

USB Tester Meter, USB C Power Meter, Current Meter, 2-in-1 Digital Multimeter, Voltage Voltmeter, Current, Charging Current, Power Capacity, Working Time Detector Ammeter with Type-C Adapter (A3)

## Features

- Multifunctional USB tester: This USB tester supports micro USB or Type-C port and fast charging mode detection, it can detect QC2.0/QC3.0, voltage/current/power/capacity detection, cable impedance measurement. A must-have gadget checks the charging performance (charging speed and quality) of the output wall/car and USB charging cable. It can also be used to test the capacity and electrical energy of the power bank. Measuring voltage: 4.5V-24.0V; measuring current: 0-8.0A
- Wide range of applications: Widely used in the quality testing of digital devices with USB-A and Type-C peripherals. Ideal for testing and determining the actual performance values of different chargers and devices, e.g. PC/laptop/desktop computer/mobile phone/power bank/charger/discharge charger/car charger/cable. With this tester, you can clearly see what happens when charging various USB devices, from iPhones to tablets to batteries.
- Flexible colour display interface: with a 1.44 inch LCD screen, 4 control buttons and 5 connection ports. Supports 360 degree rotation of the screen to allow reading at any angle. You can rotate the screen by pressing the button corresponding to the horizontal menu bar. When connected to different digital devices at any angle, positive readings can also be determined, making the measurement more comfortable
- Unbeatable design: this USB power meter with gold-plated USB contacts has a strong coating to prevent scratches, stains and damage. This upgraded USB Type-C tester can detect safety and maximally protect the devices from damage. The output is automatically interrupted while the data is saved in the event of a sudden power off.
- Important note: If the PD power supply is not connected to the fast charger, the power supply is not provided by default. Both the charger and charger must support fast charging. Since the tester is a one-sided protocol design, please try to turn the Type-C cable over if the display does not light up and try again.
