Multicomp Pro USB Tester 4-24V DC 3A

Multicomp Pro USB Tester 4-24V DC 3A is a portable load tester for USB Type A charging ports, measuring output voltage and current across a 4 V to 24 V and 0.05 A to 3 A test range.

The tester is designed to inspect the performance of USB chargers, portable power banks, data cables and other electronic charging devices. Its clear digital display shows measurements including output voltage, current, energy capacity (mAh), circuit equivalent resistance and the data line (D+ and D-) voltages of USB cables. This information can be used to verify charger specifications, diagnose faulty cables or confirm that a power source is delivering the correct output for connected devices.
