The 2UUL PW21 Mini Charging Mate is a professional-grade Type-C USB current and voltage detector purpose-built for mobile phone, tablet, and laptop repair technicians who need precise, real-time insight into the charging behaviour of any device during diagnosis and repair. Supports PD2.0/3.0, PPS, QC2.0, QC3.0, FCP, SCP, AFC, PE, DASH, VOOC, and Super VOOC fast charging protocols, allowing you to immediately identify whether the correct charging protocol is being negotiated between the charger and the device a critical diagnostic step for fast-charging faults.

Supporting bidirectional current testing up to 30V and 12A, it covers mobile phone charging measurement and power bank capacity recording, and supports detection across multiple devices. The compact inline design slots between the charger and the device without interrupting the charging session, displaying live voltage, current, power, capacity, energy, timing, and temperature simultaneously on its built-in display. Data is stored even when the phone’s power is disconnected, ensuring no measurement session is lost mid-repair.

It records the highest power in a single session, the maximum current in a single session, and the highest voltage — giving technicians a full picture of charging behaviour over time rather than just a snapshot. Compatible with iPhones, Android smartphones, iPads, tablets, laptops, and power banks, the PW21 is an indispensable tool for any professional repair bench dealing with charging port faults, battery replacement verification, cable quality testing, and charger output validation.
