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
