While this may appear to be an electronic shuriken, it's actually a Multifunctional USB Digital Tester! This handy (pun intended?) 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 pops up when you plug in a power supply. Each click of the button gives you a different display and readout. A long press will reset the data for when it does Coulomb-counting (total power consumption). We like the simple display that comes up first with big Voltage and Current output, but you have lots of options.There's 4 connectors so you can go from type A to C, type A to A or type C to C.Works great with laptops, smartphones, tablets, what have you, it's perfect for testing any USB power setup but this model is a little nicer in that it is also good for USB C with its higher current and voltage capabilities - up to 32V and 5A!If you're using this to test USB C be sure to get a cable with E-Mark power negotiation chips inside so you get the proper current and voltage out - many cheap USB C cables skip this part and won't work well for high-current/voltage charging.Technical Details * Tester Dimensions: approx 68 x 60mm / 2.6" x 2.3" * Voltage Range: 3.6V~32V * Current Range: 0~5.1A https://elecena.pl/product/22716616/multifunctional-usb-digital-tester-usb-a-and-c 2023-03-07 https://elecena.pl/product/22716616/multifunctional-usb-digital-tester-usb-a-and-c 2023-12-27 https://elecena.pl/product/22716616/multifunctional-usb-digital-tester-usb-a-and-c 2024-09-19 https://elecena.pl/product/22716616/multifunctional-usb-digital-tester-usb-a-and-c 2024-11-29 https://elecena.pl/product/22716616/multifunctional-usb-digital-tester-usb-a-and-c 2024-11-30 https://elecena.pl/product/22716616/multifunctional-usb-digital-tester-usb-a-and-c 2025-04-10 https://elecena.pl/product/22716616/multifunctional-usb-digital-tester-usb-a-and-c 2025-11-28 https://elecena.pl/product/22716616/multifunctional-usb-digital-tester-usb-a-and-c 2025-11-29
