The 2UUL PW21 Mini Charging Mate Detector is a compact USB-C tester built for technicians who need fast, accurate charging diagnostics on the repair bench. It reads voltage, current, and power output in real time, identifies fast-charging protocols automatically, and logs multi-group data for later review. With bidirectional current testing rated up to 30V and 12A, you can check charging behavior on phones, tablets, laptops, and power banks without guesswork. The compact form factor fits easily into a technician's toolkit, making it a practical daily-use tool for diagnosing dead-after-flash charging faults, checking power bank output, and confirming whether a charging issue traces back to the cable, the port, or the device itself.
