Characteristics: This voltage converter uses a high-quality industrial grade chip with high conversion rate and stability. Supports 3 intelligent protections, including over-current protection, over-temperature protection and output short-circuit protection. Copper wire has excellent electrical conductivity, low temperature, low carbon content, and saves more energy. Fireproof plastic housing and organic silicone seal technology have high thermal conductivity, IP67 penetration degree, water resistance and shock resistance. Widely used for car stereo, radio, monitoring, LED display, electric fan, motors and other electrical appliances etc. Technical data: Type: non-insulated step-down voltage converter Output Connector: Micro USB Input voltage: DC12V Output voltage: DC5V Output current: 3A, 2.5A (no need to increase heat dissipation for long-term use) Power output: 15 W Max.
