Specification: Item Type: USB C Voltage Current Tester Power Consumption: Operating Current: 0-6A (Short Time 12A) Power Display: 0-9999Wh Power Display: 0-600W Capacity Display: 0-99999mAh Operating Temperature: 0-45°C/32-113°F Sampling Resistor: 0.001R Product Size: Approx.43x25x10mm/1.69x0.98x0.39in Material: ABS Color: Orange How to Use: Function Key: Single click to cycle through different display interfaces; long press on different interfaces to clear data or clear no load data. Screen Rotation Key: Single click to rotate the display in four directions.(Pro tip: Long press the screen rotation key on the first or second interface to switch between black and white display and color display) Important Notice: When using a USB C charger, the display will only light up when both the charger and a connected device (e.g., phone) are plugged in simultaneously. packing list: 1 x USB C Voltage Current Tester 1 x User Manual 1 x Storage Box Note: Question 1: Why doesn't the product display when plugged directly into the charger? Answer: Most chargers Type C ports don't output voltage by default. In this situation, the product has no power and no display. The charger only outputs voltage when a load protocol is detected, at which point the product will display. Question 2: My charger is labeled 10A or 120W, why can't the meter measure 10A or 120W? Answer: The values ​​measured by this product are real time charging parameters during the charging process. The parameters labeled on the charger are the product's maximum power parameters, and it is not always the situation that it will output such a high value. Question 3: Why does it occasionally display a current of 0.01-0.02A when no load is connected? Answer: This product uses bidirectional current detection. A very small no load current is normal, but it can be cleared by quickly pressing and holding the function key in the current clearing interface. Question 4: Why is there a huge difference between the capacity value measured by this meter and the phone nominal battery capacity? Answer: The capacity values ​​measured in this table are the current voltage capacity values. If you need to know the capacity value of the phone's battery at 3.7V, please convert the displayed capacity value using the logical .
