Multifunctional USB Digital Tester - USB A and C

While this may appear to be an electronic shuriken, it's actually a Multifunctional USB Digital Tester!

This handy tool can measure voltage, current, power, charge time, and other measurements for USB A, Micro B, and USB C! It features a colorful display that activates when you plug in a power supply. Each button click changes the display and readout, and a long press resets the data for Coulomb-counting (total power consumption). The simple default display shows big Voltage and Current output, with multiple display options available.

The tester includes 4 connectors allowing for USB Type A to C, Type A to A, or Type C to C connections. It works great with laptops, smartphones, tablets, and is perfect for testing any USB power setup. This model supports USB C with higher current and voltage capabilities—up to 32V and 5A.

Note: For USB C testing, it is important to use a cable with E-Mark power negotiation chips to enable the proper current and voltage output, as many inexpensive USB C cables lack this feature.
