USB Power Meter for Voltage, Current, Capacity, Energy Resistance

The Klein Tools ET900 is a USB digital meter designed for common standard USB-A (Type A) ports, including Qualcomm Quick Charge ports. It is capable of accurately and reliably measuring and displaying the voltage, current, capacity, energy, and resistance of the USB port simultaneously. The device is compatible with any USB-A port that has the capability to deliver power, and it does not require batteries as it draws power from the power source.

For over 160 years, Klein Tools has been producing premium-quality, professional-grade hand tools that offer the performance, durability, and precision necessary to complete tasks effectively. With six generations of expertise, our team of engineers, workers, and craftsmen put their knowledge and skills into every tool we create.

The Klein Tools ET900 can handle voltage ranges from 3 to 20V DC and currents from 0.05 to 3A. It can continuously monitor voltage, current, capacity/charge delivered, energy, and resistance for up to 1000 hours and store and recall up to 10 readings. Additionally, it is equipped with overload detection for voltage and current, a high-resolution LCD for clear visibility in low-light environments, and a durable cable for easy access to hard-to-reach ports.
