This multifunctional USB digital tester by Adafruit is a really handy tool that everyone should consider having for their workbench. You can easily measure voltage, current, power, charge time, and more. You can even gather data for coulomb-counting, or total power consumption over time.
It’s capable of working with USB Type-A, Micro-B, and USB Type-C. It has a full-colour display and can even do total power consumption. If you need a way to measure USB power, this is a great little tool to have.
They give it a 9 out of 10, saying it’s a “A great tester for a specific task.”
