In the temperature mode of Vaporesso Target Pro, the wattage is shown real-time. I set the temperature at 315C for SS coil. The wattage has fluctuations, like 17-22w. However, sometimes the wattage is way higher at the same 315C degrees with the same SS coil, like 30-38w. The vapor is hotter and tastes burnt. What causes the difference? Is it the box malfunction?

Generally, is it better for the coil to vape in temperature mode?
