In a certain range, the better the heat dissipation, the greater the power. Low voltage products not only need to meet their voltage, but also need to pay attention to the current. If the power supply current can not meet the impact current of the product, the product will be slowly warming up, low temperature, or even short circuit. Cannot be directly immersed in water or liquid. .
