USB-C Power Meter Tester 3-36V 0-12A — PD3.1 / QC4.0 / MTK, PDO Decoding, 2-Way Voltage/Current/Capacity Monitor (Tools & Hardware)

Compact, travel-ready USB-C power meter for chargers and cables that supports PD3.1, QC4.0 and MTK fast-charging protocols with automatic detection and PDO decoding. Measures voltage from 3-36V and current from 0-12A while providing two-way measurement of Voltage/Current/Capacity for accurate charging analysis of phones, tablets and laptops. Built-in cable testing evaluates data transmission rates and precisely reports voltage and current characteristics so you can verify performance of PD E-Marker 280W fast-charging cables and troubleshoot connectors or chargers. The unit features a 1.3-inch HD IPS rotatable display with three distinct viewing pages you toggle with a click — view real-time power numbers or inspect ripple curve measurements for deeper diagnostics. Housed in a CNC-machined metal shell, the tester is dust- and impact-resistant and sized at 54.9x24.4mm for easy pocket or bag carry. Multiple onboard safety protections guard against overheating and overcharging, and continuous real-time readouts help you maintain healthier battery charging behavior and maximize charging efficiency.
