The Klein Tools ET910 is a USB digital meter and tester combination for most common USB-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 also test the maximum current delivery capability of the USB port with built-in fixed loads so user need not connect to an external load. It will 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.Warnings Do NOT use with ports that operate outside of the rated voltage and current. NEVER use on a circuit with voltage or current that exceeds the maximums specified for this device. Do NOT use during electrical storms or in wet weather. Do NOT use if meter appears damaged. Use caution when working with voltages above 25V RMS or 24V DC. Such voltages pose a shock hazard. This meter will NOT display current below 50 milliamperes, even if it is allowing this to pass through. NOTE: The display will show zero current. To ensure safe operation and service of this meter, follow all instructions. Failure to observe warnings can result in severe injury or death.
