DROK Digital Multimeter USB 2.0 and USB Load Tester

A Bundle of Digital Multimeter USB 2.0 and USB Load Tester

• Digital Multimeter USB 2.0 --- 7-Mode USB Monitor ---- With 7 mode, 1 button to operate. Voltage measuring range DC 3. 20~30. 0v; Current measuring range 0. 00~3. 00A
• Digital Multimeter USB 2.0 --- Multifunction ---- Can be used for capacitance checking, capacitance clear, over voltage and under voltage alarm, over-current, and short circuit alarm, easily test the power/quality of the chargers and USB cables.
• Digital Multimeter USB 2.0 --- Dual USB Output ---- Two USB output available, can be used simultaneously. Output I: be used for device charging and data transfer; output II: only for charging mobile phones, tablet PCS and etc. Output I Support QC 2. 0 9V & 12V charging, but don't insert any device in Output II when using QC 2. 0 Charging.
• USB Load Tester --- Easy Opeartion --- Set the load to resume normal operation manually or automatically after releasing the protection condition; can freely set the boot state to be on or off by default; 4-bit led digital display; check the load voltage value / current value / power value; intelligent temperature control cooling fan; Precision adjustable potentiometer.
• USB Load Tester --- Protection Function --- OVP overvoltage protection (25V-30V overvoltage protection, digital display OVP, permanent damage after more than 30V); OPP over-power protection (load temperature is greater than 80 °C, the device stops working, digital display OTP); OTP over-temperature protection (power greater than 25W, equipment stops working, digital display OPP).
