USB Digital Meter, USB-A (Type A)

The Klein Tools ET900 is a USB digital meter for common standard USB-A (Type A) ports including Qualcomm Quick Charge® ports. It accurately and reliably measures and displays the USB port voltage, current, capacity, energy, and resistance simultaneously. It can function with any USB-A port that has the ability to deliver power. It requires NO batteries as it draws power from the power source to function.

• 3 to 20V DC; Current: 0.05 to 3A
• Continuously monitor up to 1000 hours of voltage, current, capacity/charge delivered, energy, and resistance (calculated)
• Tests most common standard USB-A ports, including Qualcomm Quick Charge® ports
• Store and recall up to 10 readings
• Voltage and current overload detection
• Hi-resolution LCD for clear visibility in environments with low ambient lighting
• Durable cable to allow easy access to hard-to-reach ports
