Notes:
1. If nothing displaying or no sound, which might fail to power up the USB meter, please check if the USB port is connected well.
2. If there were inaccurate tested capacitance, please note there are different capacitance computing methods for charging cell phone or discharging power bank.
- 6 IN 1 MULTI TESTER: This DMM USB meter is a practical USB tool for measuring voltage, current, temperature, capacitance, energy, power and time simultaneously; It is very handy to detect whether the output voltage or current from computer, home charger, USB car charger and wall charger are acceptable for your mobile device.
- HIGH QUALITY LCD PANEL: Our digital multimeter adopts 0.96″high quality LCD monitor is bright and clear, with great advantage of low power consumption. Four various display modes for choice, you can enjoy the whole using process.
- UNIQUE SAFE DESIGN: The multiple meter is equipped with sensitive auto alarm system (high/low voltage protection threshold and over-current protection threshold), and three alarm mode (buzzer alarm +double warning prompts +timing shutdown), hence safe for use.
- MULTIFUNCTION: The versatile USB Detector can be used for capacity storage and has over voltage and under voltage protection. It also support QC 2.0/3.0 fast charging and automatically cut off when the device is full charged, effectively protect your device.
- EFFORTLESS AND SIMPLE OPERATION: ONLY press one button can achieve the switch of multi functions, such as switch display, clear values. No complicated wiring or other tools, you can easily detect the quality of your power bank, USB chargers.
