YEREADW USB-C Tester Power Meter 2-in-1 | Digital Multimeter 3.6–32V, 0–8A | PD/QC Fast-Charging Compatible

Overview

Meet the YEREADW USB-C Tester Power Meter 2-in-1, a compact tool designed to bring clarity to your charging setup. It blends a precision volt-amp meter with versatile data readouts, helping you assess performance across wall chargers, USB hubs, and solar chargers. The crystal-clear IPS display reveals voltage (3.6–32V), current (0–8A), and essential metrics in a single glance, making it easier to understand how your devices draw power.

What you can measure

Capture real-time data as you plug in phones, laptops, portable batteries, and power banks. The tester supports both direct load testing and calculation-based capacity checks, so you can estimate how much energy a power bank can deliver and how efficiently your charger converts input energy.

• Voltage: 3.6V–32V range to accommodate USB-C and USB-A devices
• Current: 0–8A for faster chargers and high-drain devices
• Capacity and energy: Wh and Ah estimates based on measurements
• Power and impedance: quick insights into overall charging performance

Wide compatibility with fast charging protocols

This tester supports PD 3.0/2.0, QC 3.0/2.0, BC1.2. It covers a broad set of devices—from the latest smartphones to laptops and ultrabooks that use Type-C or USB-A ports.

• PD and QC protocol support across USB-C and USB-A
• Works with consumer devices including phones, laptops, tablets, and portable chargers

Safety first, with data resilience

Built-in protections guard against over-voltage, over-current, under-voltage, and low energy. If a fault is detected, the tester can automatically cut power to protect your devices. It also preserves data during unexpected outages, so you can resume tests without losing results.

Ease of use and a crisp, flexible display

The updated IPS color display offers eight color themes and intuitive navigation. Switch views to monitor voltage, current, capacity, power, load impedance, and more—dedicated sections help you compare scenarios at a glance.

Practical uses and tips

Ideal for evaluating new chargers, checking power bank health, and validating fast-charging setups. By measuring actual voltage under load, you can infer how devices perform under real-world conditions and adjust charging gear accordingly.
