Yunsailing 2-Pack 200A High-Precision Watt Meter Power Analyzer – Backlit LCD, 100V Range

Two-Pack Power Insight You Can Rely On

Meet the Yunsailing 2-Pack Power Meter and Watt Meter — small, precise tools designed to illuminate how energy flows through your projects. Each unit features a bright blue backlit LCD screen that remains readable whether you’re testing in daylight or dim conditions. With two monitors in the box, you can set up one for a live test and keep the other ready for backup, sharing with a friend, or gifting to a fellow enthusiast.

What it Can Do

• Clear readability in any light: a backlit display ensures voltage, current, and power readouts stay legible in sun or night.
• Accurate energy tracking: it detects maximum voltage and calculates voltage, current, power, discharge time, and energy usage for quick assessments.
• High precision within a safe range: designed for 12–100V and 0–200A, with fine resolutions (0.01 for volts and amps, 0.01W for power, 0.001Ah for capacity).
• Versatile applications: suitable for evaluating RC battery charging efficiency, monitoring power consumption of battery-powered devices, and checking operating voltage across components.
• Durable, low-resistance design: tin copper core minimizes resistance, and an integrated exhaust vent helps dissipate heat for longer service life.
