UT658 USB tester is a new equipment to test the quality of charger/power bank for 3C products. It can give a comprehensive detection for the charging equipment, such as output voltage, output current, output capacity, output voltage stability, etc. With this instrument, you can test charging current with different charging cable, allowing you to select the optimal charging cable and saving the charging time for you.

Features:
Real time detection: test voltage, current and charging capacity.
LCD display with multiple data, easy and clear for readings.
DC3-9V voltage test range, 0-3A current range, ±1% accuracy.
Voltage alarm function: when the voltage is higher than 5.3V(display "H") or lower than 4.7V(display "L").
With data storage function: memorize 10 groups of capacity data.
Quick capacity data review and zero clearing function.
U-disk current detection and USB interface voltage detection.
Improve the charging efficiency and protect the charging equipment.
